When people hear the word seafarer,nowadays also shefarer is popular word. They usually imagine endless oceans, beautiful sunsets, and traveling around the world. Others picture long contracts, isolation, and missing birthdays, weddings, and family gatherings.

The truth is that both pictures are correct.

As someone who has spent years working at sea, I often receive the same question:

“Are seafarers really happy?”

There is no simple yes or no answer because every seafarer has a different story. But there is one thing many of us have in common—we didn’t choose this career simply because we love the sea. We chose it because it offered opportunities we could never have found at home.

Imagine you are 18 years old.

You have never left your village. Your family works hard just to pay the bills, and finding a job that pays even USD 200 per month is considered a good opportunity. University may not be affordable, and supporting your family becomes more important than following your dreams.

Then someone tells you about the ships.

After completing the required training, you join your first vessel as an Ordinary Seaman. Suddenly, your monthly salary may be three or four times higher than anything you could earn back home.

Your accommodation is provided.

Your meals are provided.

You don’t pay rent.

You don’t pay electricity or water bills.

Even internet access, although often limited, is usually available onboard.

Your contract may last around six months, and if you manage your money wisely, you can return home with significant savings—something that would have been almost impossible in your previous circumstances.

For many people, shipping is not just a profession.

It is a way to completely change the future of an entire family.

If you have the opportunity to study at a maritime academy, the possibilities become even greater. Graduating as a Third Officer or Third Engineer can lead to starting salaries of around USD 3,000 or more, depending on the company, vessel type, and nationality. With experience, promotions to Chief Officer, Chief Engineer, or Captain can provide incomes that many people in developing countries could never imagine.

That is why countries such as the Philippines supply one of the largest numbers of seafarers in the world.According to International Chamber of Shipping 1,9 million seafarers exist all around the ships and 460.000 of Filipino men and women work onboard merchant ships because the profession offers financial stability not only for themselves but also for their families waiting at home.

This pattern is repeated across many countries in Asia, Eastern Europe, Africa, and South America.

Many of us come from modest backgrounds. Shipping became our opportunity to build a better life.

But there is another side to the story.

Every dollar earned at sea comes with a price.

You miss birthdays.

You miss anniversaries.

Sometimes you miss the birth of your own child.

You spend months away from your partner, parents, and friends. You celebrate holidays through video calls, and sometimes poor internet means you cannot even do that.

People often ask whether life onboard is difficult and sometimes it really is , lonely , exhausting.

But sometimes, at two o’clock in the morning, when your watch is quiet and the ocean is completely calm, you look up at a sky filled with thousands of stars. There are no city lights, no traffic, no noise—only the sound of the sea.

In those moments, you realize that very few people on Earth will ever experience what you are seeing.

That feeling is impossible to describe unless you have lived it yourself.

So, are seafarers happy?

Some are.

Some are not.

Most of us simply accept that this career is a trade-off. We sacrifice time with the people we love in exchange for opportunities that can transform our lives and the lives of our families.

For many of us, the sea is not our dream.

It is the bridge that allows us to reach it.

This article is the first in my Life at Sea series, where I’ll share real experiences, honest opinions, and untold stories from the world of merchant shipping.

If you’ve never worked onboard, I hope these articles help you understand what life at sea is really like.

And if you’re a fellow seafarer, you may find parts of your own story here as well.

In maritime transportation, one of the most fundamental concepts is navigation. At its core, good navigation means getting a vessel from its departure point to its destination as safely and efficiently as possible.

In conventional voyage planning, this usually means finding the most efficient route between the port of departure and the destination while maintaining an acceptable level of safety. For shipowners, charterers and operators, every additional nautical mile can translate into higher fuel consumption, longer voyage duration, additional crew costs and increased exposure to operational risks.

This becomes even more important on long-distance trades connecting Asia with Europe and North America. When a vessel spends several weeks at sea, even a small change in voyage duration or routing can have a significant financial impact.

For decades, the Suez Canal has been one of the most important shortcuts connecting Asia and Europe. However, geopolitical instability, attacks on commercial shipping, the Houthi threat in the Red Sea and wider tensions across the Middle East have fundamentally changed the economics of this route.

As a result, some shipping companies have chosen to avoid the Red Sea and instead sail around the southern tip of Africa via the Cape of Good Hope.

The decision seems obvious.

The Cape route is much longer.

The vessel consumes more fuel.

The voyage takes more days.

So why would any shipowner voluntarily choose it?

The answer is much more complicated.

---

Suez Canal vs Cape of Good Hope: The Basic Question

Imagine a tanker sailing from Hong Kong to Rotterdam.

Should the vessel:

1. Sail through the Suez Canal and Red Sea, or
2. Avoid the Red Sea and sail around the Cape of Good Hope?

The answer cannot be determined by distance alone.

A professional voyage comparison needs to consider:

• Sailing distance
• Voyage duration
• Fuel consumption
• Bunker prices
• Suez Canal transit fees
• Charter hire
• Crew costs
• Additional operational expenses
• Insurance
• War-risk exposure
• Security risks
• Waiting time
• Cargo delivery requirements

This is where the economics of maritime transportation become particularly interesting.

Our Example: A 32,000 DWT Oil/Chemical Tanker

For this comparison, let’s use  32,000 DWT oil/chemical tanker with the following characteristics:

Vessel Parameter	Assumption
Length overall	180 m
Beam	28 m
Deadweight	32,000 DWT
Average speed	12.5 knots
Fuel consumption	22 MT/day
Fuel type	VLSFO
Departure	Hong Kong
Destination	Rotterdam
VLSFO price assumption	$806/MT

The vessel has two realistic routing options.

Route 1 — Via Suez Canal

Hong Kong → Indian Ocean → Red Sea → Suez Canal → Mediterranean → Rotterdam

Approximate distance:

10,077 nautical miles (18,662 km)

Route 2 — Via Cape of Good Hope

Hong Kong → Indian Ocean → Cape of Good Hope → Atlantic Ocean → Rotterdam

Approximate distance:

13,741 nautical miles (25,448 km)

That means the Cape route adds approximately:

3,664 nautical miles

or about 36% more distance than the Suez route in this scenario.

---

Voyage Duration: Suez Has a Major Advantage

At an average speed of 12.5 knots, our vessel would require approximately:

Suez route

33 days 14 hours

Cape of Good Hope route

45 days 18 hours

That creates a difference of approximately:

12 days 4 hours

In other words, using the Suez Canal could theoretically get the cargo to Rotterdam almost 12 days earlier.

That is a huge advantage.

But time is not the only variable.

---

Fuel Consumption: How Much Does the Cape Route Cost?

Our tanker consumes approximately 22 metric tonnes of VLSFO per day.

Using the voyage durations above:

Suez route

33.58 days × 22 MT/day

≈ 739 MT of fuel

Cape route

45.75 days × 22 MT/day

≈ 1,007 MT of fuel

Using the assumed bunker price of $806 per metric tonne:

Cost Item	Suez	Cape of Good Hope
Voyage duration	33.6 days	45.8 days
Fuel consumption	~739 MT	~1,007 MT
Fuel price	$806/MT	$806/MT
Fuel cost	~$595,000	~$812,000

So the Cape route consumes approximately:

268 additional tonnes of fuel

or roughly:

$217,000 more in bunker costs

That sounds like a strong argument for Suez.

But we haven’t included the biggest variable yet.

The Suez Canal itself.

Note: the $806/MT figure is retained as the article’s scenario assumption. Actual bunker prices vary significantly by port and date; recent Hong Kong VLSFO assessments have been around the $800+/MT range.

---

The Hidden Cost of the Suez Canal: Transit Fees

The Suez Canal is not a free shortcut.

The Suez Canal Authority (SCA) charges vessels for transit, with normal dues calculated primarily according to the vessel’s Suez Canal Net Tonnage (SCNT) and vessel type. The SCA also maintains an official toll calculator and updates its toll structure periodically.

For our hypothetical tanker, we can use an estimated Suez transit charge of approximately:

$438,000

This changes the calculation totally.

Before the canal fee, the Suez route appeared cheaper by approximately $217,000 in fuel.

After adding the canal transit fee:

$595,000 + $438,000 = ~$1.033 million

Suddenly, the financial advantage is much smaller.

And we still haven’t considered the cost of the additional 12 days required by the Cape route.

---

The Cost of Spending 12 Extra Days at Sea

A vessel does not operate for free.

Every additional day at sea generates costs.

For our scenario, let’s assume:

• Additional crew-related costs: ~$30,000
• Additional operating expenses: ~$50,000
• Additional charter hire: ~$300,000

That gives the Cape route approximately:

$380,000 in additional non-fuel voyage costs

Add this to the Cape route’s bunker bill:

$812,000 + $380,000 = ~$1.192 million

At this point, it appears that Suez is still cheaper.

But this is where the modern Red Sea shipping environment changes the equation.

---

The Biggest Variable: Security and War-Risk Insurance

The problem with the Suez route is not simply the canal.

A vessel sailing from Asia to Rotterdam through Suez must also enter the Red Sea and pass through the Bab el-Mandeb region.

That creates an entirely different category of risk.

In normal circumstances, insurance is simply another operating cost.

In a high-risk war zone, however, the cost of insurance can change dramatically.

Recent market conditions demonstrate how quickly this can happen. In July 2026, Reuters reported that war-risk premiums for vessels operating in the southern Red Sea had increased sharply following attacks on commercial tankers, with some quoted rates reaching several percent of vessel value depending on the voyage and risk exposure.

The wider Middle East situation has also pushed marine war-risk costs substantially higher, with S&P Global reporting in July 2026 that additional war-risk premiums for some voyages through the Strait of Hormuz had reached 7.5–10% of hull value.

This is why simply comparing fuel consumption is no longer enough.

---

Why Insurance Can Change the Entire Calculation

Let’s use a simplified scenario.

Suppose the additional security and insurance exposure associated with the Suez/Red Sea route adds approximately:

$500,000

to our voyage economics.

This is not intended as a universal insurance quote. Actual war-risk premiums depend on vessel value, flag, ownership, charterer, cargo, route, security conditions, insurer and the precise area entered.

But for our scenario, adding $500,000 makes the comparison much more interesting.

Suez Route

Cost	Approximate Amount
Fuel	$595,000
Suez Canal transit	$438,000
Additional security/insurance exposure	$500,000
Total	~$1.533 million

Cape Route

Cost	Approximate Amount
Fuel	$812,000
Additional crew costs	$30,000
Additional operating costs	$50,000
Additional charter hire	$300,000
Total	~$1.192 million

If we then assume approximately one day of waiting time associated with Suez and deduct around $25,000 from the Cape route’s incremental time-related cost, the Cape option remains around:

~$1.17 million

That produces a difference of roughly:

$360,000 in favour of the Cape of Good Hope route.

---

So, Should Every Ship Avoid Suez?

Not necessarily.

And this is the most important lesson from this comparison.

A route cannot be judged solely by:

“Which route is shorter?”

The real question is:

Which route provides the best combination of cost, time, safety and reliability for this particular cargo and vessel?

For a tanker carrying relatively time-insensitive cargo, accepting an additional 10–14 days at sea may be economically rational if it substantially reduces exposure to war risk and unpredictable insurance costs.

For a container ship carrying high-value or time-sensitive cargo, the calculation can be very different.

---

Why Do Container Ships Still Care About Transit Time?

Imagine a container ship carrying:

• Smartphones
• Computers
• Tablets
• Cars
• Machinery
• Spare parts
• Clothing
• Consumer electronics
• Industrial components
• Perishable goods

The cargo inside a container ship can represent an enormous amount of economic value.

For many of these products, time has a financial value.

A retailer waiting for a shipment does not necessarily care that a vessel saved $200,000 in bunker costs.

They care about receiving their inventory on time.

A manufacturer may be waiting for a critical component.

A supermarket may need perishable products.

An automotive plant may need spare parts.

This creates a completely different economic equation.

---

The Cost of a Longer Route Eventually Reaches the Consumer

This is where maritime transportation becomes directly connected to everyday life.

When a shipping company chooses the Cape of Good Hope instead of Suez, it may have to pay for:

• More fuel
• More crew time
• More vessel operating days
• More charter hire
• Additional maintenance exposure
• Additional port and scheduling complexity
• Higher inventory costs
• Longer cargo transit times

Those costs do not simply disappear.

They are distributed throughout the supply chain.

A shipping company may increase freight rates.

A freight forwarder may adjust its charges.

An importer may increase its landed cost.

A distributor may adjust its pricing.

And eventually, part of that additional transportation cost can reach the final consumer.

This is one of the reasons why disruptions to major maritime chokepoints can have economic consequences far beyond the shipping industry itself.

Research on maritime chokepoint disruptions has shown that rerouting can create wider network effects because longer voyages delay vessels and reduce effective shipping capacity elsewhere in the network.

So when consumers notice that imported goods are becoming more expensive, the explanation may sometimes be much further away than the local shop.

It may begin thousands of nautical miles away.

---

Suez Canal vs Cape of Good Hope: The Real Winner

Our 32,000 DWT tanker produces an interesting result.

Factor	Suez Canal	Cape of Good Hope
Distance	10,077 nm	13,741 nm
Voyage time	33.6 days	45.8 days
Fuel consumption	~739 MT	~1,007 MT
Fuel cost	~$595k	~$812k
Canal fee	~$438k	$0
Additional time-related costs	Lower	Higher
Security exposure	Higher	Lower
War-risk exposure	Higher	Lower
Estimated total in our scenario	~$1.53M	~$1.17M
Best advantage	Speed	Predictability & security

So, despite being almost 3,700 nautical miles longer, the Cape of Good Hope route can become economically attractive when the cost of security, insurance and geopolitical risk is included.

That is the real lesson.

The shortest route is not always the cheapest route.

And in modern shipping, the safest route can sometimes be the most economical route—even when it takes nearly two weeks longer.

A note on the calculations

The figures in this article are illustrative voyage-planning assumptions, not a commercial quotation. Actual results will vary according to vessel particulars, SCNT, draft, cargo, weather, speed, fuel consumption, bunker prices, canal tariffs, charter terms, insurance conditions, waiting time and geopolitical risk.

The Suez Canal Authority itself states that canal dues are calculated using the vessel’s SCNT and that its toll calculator provides an estimate; therefore, an actual vessel’s official Suez invoice may differ from the simplified figure used in this example.

As the entire world continues to expand digitalization, the maritime industry has also entered the digital age. With the younger generation becoming increasingly dependent on social media and the internet, one of the most important questions for people considering a career at sea today is whether they will have internet access onboard.

So, do modern ships really have internet access? If so, how fast is it? Is it good enough for everyday use? And are there any data limits?do you have to pay for it ?

In the past, when seafarers began a voyage, they could generally only receive messages through satellite communication systems in emergencies or communicate through radio waves. Once a ship left port, staying connected with the outside world was extremely limited.

Today, however, modern merchant ships can provide internet access through satellite communication systems, allowing seafarers to remain connected even when they are thousands of miles away from land.

How Common Is Internet Access Onboard?

The popularity of internet access at sea began to increase significantly after 2015 and has now reached a very high level.

According to the 2019 ICS/ECSA survey, which covered 11,655 ships, approximately 85% of the vessels surveyed provided internet access for crew use. Those vessels represented around 14% of the global fleet at the time.

Today, this figure is believed to be considerably higher, with some estimates suggesting that around 95% of merchant vessels may now provide internet access to their crews.

I personally know hundreds of seafarers working in different ships of companies including European,Asian and American based companies, and based on my experience, only around 2–3 out of every 100 seafarers I know are currently working on ships without crew internet access.

These vessels tend to be older, smaller-tonnage ships, often operating under flags or in regulatory environments where requirements for crew welfare and connectivity may be less demanding.

If we assume that there are approximately 70,000 merchant vessels above 1,500 gross tonnage worldwide, this could mean that around 66,000 ships may now have some form of internet access onboard.

For a newly graduated maritime student preparing for their first contract, or a cadet about to begin their sea training, probably will have internet access onboard.

But having internet access is only one part of the story.

How fast is it? How reliable is it? How much data are you allowed to use? And is it actually good enough for everyday life?

How Fast Is Internet at Sea?

Looking at the world’s merchant fleets, Starlink has become one of the most widely discussed and increasingly popular connectivity solutions.

Satellite internet existed long before Starlink entered the maritime market. However, Starlink has extremely changed the competitive landscape by making high-speed satellite internet considerably more accessible.

For example, older satellite internet systems could cost around $25 for a very limited amount of data up to 100 Mb, while modern Starlink-based systems can provide higher speeds and much greater data allowances.

This can be seen as one of the major changes Starlink has brought to the maritime industry.

As competition increased, seafarers gained access to much better connectivity at a significantly lower cost compared with traditional satellite communication systems.

Today, Starlink is operational across a large part of the world’s oceans and, depending on the vessel’s location, service configuration and network conditions, can provide speeds that are more than sufficient for normal social media and communication.

TikTok, Facebook, Instagram, WhatsApp and many other apps can generally be used without the frustrating experience that was common with older satellite systems.

However, there is one major problem.

Fast internet can make your data allowance disappear extremely quickly.

How Much Internet Do Seafarers Get?

There is no single standard across the maritime industry.

Every shipping company can have a different policy regarding crew internet. Some companies provide extremely generous or even unlimited access, while others impose strict daily or monthly limits.

For comparison, if you purchase a residential Starlink service for your home, plans such as those available in Europe can offer unlimited data.

🏠 Starlink Residential

Plan	Speed	Data	Monthly Price*
Residential 100 Mbps	Up to 100 Mbps	Unlimited	$55/month
Residential 200 Mbps	Up to 200 Mbps	Unlimited	$85/month
Residential Max	400+ Mbps	Unlimited	$130/month

*Prices are provided for comparison and may vary depending on country and service conditions.

On ships, however, the situation can be very different.

🚢 Starlink Maritime – Global Priority

Plan	Monthly Data	Starting Price*	Typical Use
Global Priority 50 GB	50 GB	$250/month	Small usage / backup
Global Priority 500 GB	500 GB	$650/month	Small crew / moderate usage
Global Priority 1 TB	1 TB	$1,150/month	Higher usage
Global Priority 2 TB+	2 TB+	Higher	Large vessels / heavy crew usage

*Prices are indicative and may vary depending on the service configuration, country and commercial agreement.

However, shipping companies do not necessarily purchase a plan and simply divide the entire allowance equally among crew members.

Most companies need a significant portion of the available bandwidth for operational purposes. Ships continuously exchange reports, emails, documents and other information with their offices, charterers, agents and other parties.

Therefore, assuming a vessel has a 1 TB monthly allowance, a company might reserve approximately 500 GB for operational and business communications.

If there are 20 crew members onboard, this would leave approximately:

500 GB ÷ 20 crew members = 25 GB per person per month.

Some companies manage this through an IT-controlled system where each crew member receives a daily allowance.

For example, a company could provide 1 GB per day, with the allowance resetting every 24 hours.

This is actually a very effective system because even if a seafarer accidentally consumes their entire daily allowance, they do not lose their entire monthly quota. They simply wait for the next daily reset.

What Can You Do With 1 GB Per Day?

Based on my own experience at sea, 1 GB per day can actually provide a reasonable level of connectivity if it is managed properly.

Depending on video quality and network conditions, you could potentially:

• Make several hours of WhatsApp video calls every day.
• Spend hours browsing X, Reddit or LinkedIn, where video consumption is generally lower.
• Use Instagram for roughly 30–45 minutes.
• Watch around 20 minutes of YouTube in Full HD.
• Stay connected with friends and family through messaging apps.

The important point is to make sure that there are no large background downloads or automatic updates running on your device.

If you disable automatic app updates, cloud backups and other background data-heavy services, 1 GB per day can be surprisingly useful.

Some Companies Offer Unlimited Internet

Of course, there are also highly competitive shipping companies that provide unlimited Starlink access to their crews.

In these cases, a single seafarer can consume more than 100 GB per month without paying anything extra.

With such a connection, you can download and upload videos, use social media freely and, during periods when relatively few people are online, you may even be able to play online games such as Counter-Strike 2 or League of Legends.

For seafarers, this is an enormous improvement compared with the internet experience of previous generations.

Not Every Company Provides Free Internet

Unfortunately, some companies also see crew internet as an additional source of revenue.

Instead of providing internet as part of the crew welfare package, they may sell data to their employees.

In some cases, seafarers can be charged as much as $10 per GB.

This means that the company may pay for the Starlink service while recovering part of the cost directly from the crew through individual data charges.

Because there are thousands of shipping companies operating different types of vessels under different management structures, the range of policies is extremely wide.

You can find everything from almost no internet at all to completely unlimited high-speed Starlink access.

Does Internet Access Have Any Disadvantages?

Despite all of its advantages, onboard internet connectivity also has a negative side.

Some companies have introduced restrictions on internet use on the bridge because of concerns that excessive connectivity could increase the risk of distraction and accidents.

A bridge is a workplace where situational awareness and concentration are critical. Social media notifications, video calls or messages from shore can easily become distractions if they are not managed properly.

There is also another problem.

Having high-speed internet onboard means that a ship’s crew can potentially remain in constant communication with the company’s shore-based office.

Instead of waiting until the next port or communicating only through scheduled reports, crew members can now receive messages, requests and instructions almost instantly.

For seafarers, this can sometimes feel like having the office sitting in your pocket 24 hours a day.

And that is certainly not always a good thing.

The New Reality of Life at Sea

When we consider all of these factors, one thing is clear: being completely disconnected from the outside world is no longer a normal part of modern seafaring.

For today’s seafarers, social media, video calls and instant messaging have become a normal part of life onboard.

A cadet joining their first vessel today is far more likely to be able to speak with their family regularly than a seafarer from previous generations.

This is particularly important for seafarer welfare.

Being able to see your family, speak with your children, follow world events and maintain relationships while working thousands of miles from home can have a significant positive impact on life at sea.

However, internet access should be treated as a tool rather than something that controls your life.

Modern ships need to adapt to the digital world, and internet connectivity is now one of the most important aspects of modern seafarer welfare.

But like everything else onboard, balance is essential.

The internet can help us stay connected with the world, communicate with our loved ones and improve our quality of life at sea.

At the same time, we should never allow it to make us forget why we are onboard in the first place: to work safely, fulfill our responsibilities and return home safely.

Seafarers Are Paying the Price While the World Watches: Why Maritime Safety Can No Longer Wait

The global economy depends on maritime transportation. Nearly 85% of international trade by volume is carried by sea, making merchant shipping one of the most essential components of global commerce. Every day, thousands of merchant vessels transport crude oil, LNG, grain, food, raw materials, vehicles, and manufactured goods across the world’s oceans.

Yet despite this critical role, commercial ships are increasingly becoming targets in geopolitical conflicts.

During the past two months alone, dozens of security incidents have been reported in and around the Strait of Hormuz. In the Black Sea, the ongoing war between Russia and Ukraine has also exposed commercial shipping to repeated attacks, with more than 50 merchant vessels reportedly affected since June 2026. These incidents have resulted in the deaths and injuries of numerous seafarers whose only mission was to transport cargo—not participate in war.

Once again, the maritime industry has witnessed a troubling reality: civilian seafarers continue to bear the consequences of conflicts they have no part in.

IMO Condemns the Attacks, But Practical Solutions Remain Limited

Following the recent escalation in the Strait of Hormuz, the International Maritime Organization (IMO) convened its 137th Council Session to address the growing threat to international shipping.

The Council strongly condemned attacks on civilian commercial vessels operating in and around the Strait of Hormuz and called for an immediate de-escalation of regional tensions.

In its adopted resolution, the IMO reaffirmed that the right of transit passage through international straits must not be threatened, obstructed, or suspended. The Council also stressed that any measures affecting navigation should remain fully consistent with international law and the International Convention for the Safety of Life at Sea (SOLAS).

Furthermore, the IMO requested its Secretary-General to work with coastal states, member governments, and the shipping industry to explore practical measures that would support the safe and uninterrupted movement of commercial vessels through the Strait.

While these statements reaffirm important legal principles, many seafarers continue to ask a simple question:

Who will protect the crews sailing through active conflict zones today?

Fear Is Changing the Shipping Industry

The impact is no longer limited to damaged vessels.

Across the maritime industry, many seafarers are becoming increasingly reluctant to accept contracts on ships trading to high-risk areas. Reports from within the industry indicate that some shipowners have struggled to recruit crews willing to sail through the Strait of Hormuz despite significantly increased wage offers.

No amount of additional salary can fully compensate for the possibility of becoming the next civilian casualty of a missile or drone attack.

A similar situation is developing in the Black Sea.

Commercial vessels operating near Ukrainian ports have repeatedly been exposed to missile, drone, and explosive attacks. Regardless of flag, nationality, or cargo, merchant ships navigating near conflict areas now face unprecedented risks. Civilian shipping has effectively become caught in the middle of geopolitical confrontation, leaving innocent seafarers to pay the highest price.

The Human Cost Behind Global Trade

Behind every merchant vessel are ordinary people.

Captains, officers, engineers, ratings, cooks, and cadets leave their families for months at a time to ensure that fuel reaches power stations, grain reaches countries in need, and global supply chains continue functioning.

These men and women are not soldiers.

They are civilians performing one of the world’s most essential professions.

Yet they continue to sail through regions where missiles, drones, and armed attacks have become increasingly common.

What Should Be Done?

The international community should move beyond statements of concern and begin implementing practical protective measures.

One possible solution would be the establishment of internationally coordinated maritime safety corridors in both the Strait of Hormuz and the Black Sea. Such corridors, supported by coastal states and protected through coordinated naval security arrangements under international law, could significantly reduce the risks faced by commercial shipping while preserving freedom of navigation.

Without meaningful action, the consequences will extend far beyond the maritime industry.

Disruptions to oil exports, grain shipments, LNG deliveries, and raw material transportation could drive up energy prices, food costs, insurance premiums, and freight rates, affecting economies and consumers around the world.

The World Cannot Afford to Ignore Seafarers

Seafarers are the invisible workforce behind global trade.

Every day they keep supply chains moving despite increasingly dangerous conditions. Yet many within the maritime community believe that their safety has not received the level of international attention it deserves.

Organizations, governments, industry leaders, and international institutions all have a role to play in ensuring that civilian merchant ships remain protected under international law.

Freedom of navigation is more than a legal principle—it is the foundation of global commerce.

Protecting commercial shipping means protecting the people who make global trade possible.

If the international community fails to act decisively, the next victims of geopolitical conflict may once again be innocent seafarers simply doing their jobs.

Who is the Captain.

Many people imagine a ship captain standing on the bridge, giving orders while sailing across the ocean also movies often show captains as the absolute authority on board who make every decision independently.

The reality is quite different.

Modern merchant shipping has changed dramatically over the past two decades. Today, a captain remains the highest authority on board, but many decisions are closely monitored by shipping companies through strict Safety Management Systems (SMS), regulations, and shore-based management. In many situations, the captain acts as the link between the vessel and the company’s office, ensuring that every operation complies with international regulations and company procedures.

Although the captain is the person ultimately responsible for the vessel, a ship operates because of the teamwork of every crew member on board.

In this article, we will explore the real responsibilities of a merchant ship captain, what a typical working day looks like, and how much captains earn in today’s shipping industry.

---

What Are the Duties of a Ship Captain?

The captain (also called the Master) is the highest-ranking crew on board and carries ultimate responsibility for the vessel, its crew, cargo, and the protection of the marine environment.

---

1. Leading the Crew

A captain is responsible for leading everyone on board, from deck officers and engineers to ratings and catering staff.

Leadership is far more than simply giving orders. A good captain creates discipline, maintains morale, resolves conflicts, and ensures that every crew member understands their responsibilities.

Ultimately, the captain is responsible for creating a safe and professional working environment.

---

2. Supervising Voyage Planning

Although the navigation officers prepare the voyage plan, the captain reviews and approves it before departure.

The captain must verify that:

• Navigation routes are safe
• Weather conditions have been considered
• Environmental regulations are followed
• Required publications are updated
• The voyage complies with company policies

If an accident occurs, the captain is responsible for the decisions made during the voyage.

---

3. Communication with the Company

A captain is the official representative of the shipowner.

Every important matter involving cargo operations, crew issues, port authorities, inspections, or emergencies is normally communicated through the captain.

Accurate communication is essential because incorrect information can lead to delays, financial losses, or legal problems.

---

4. Implementing the Safety Management System (SMS)

Every merchant vessel operates under an approved Safety Management System.

The captain ensures that company procedures are followed correctly and that all required documentation is completed.

This includes:

• Maintenance records
• Safety meetings
• Risk assessments
• Permit-to-work systems
• Emergency drills
• Internal audits

In many ways, a modern merchant ship functions like a floating company office.

---

5. Improving Safety Procedures

A captain does not simply follow company procedures.

If a procedure is ineffective or creates unnecessary risks, the captain can recommend improvements through safety reports or the Master’s Review.

These recommendations help shipping companies improve safety across their entire fleet.

---

6. Reporting Accidents and Emergencies

Any accident, near miss, pollution incident, equipment failure, or security issue must be reported immediately to the Designated Person Ashore (DPA).

The captain works closely with shore management to resolve emergencies while protecting the crew, vessel, cargo, and environment.

---

7. Monitoring Planned Maintenance

Every vessel follows a Planned Maintenance System (PMS).

The captain oversees maintenance activities carried out by deck and engine departments, ensuring that critical equipment remains operational.

Typical maintenance includes:

• Crane greasing
• Winch inspections
• PV valve overhauls
• Lifeboat servicing
• Firefighting equipment inspections
• Navigation equipment testing

The captain monitors maintenance progress and explains any overdue jobs to the company.

---

8. Training the Crew

A well-trained crew can prevent accidents and save lives.

The captain ensures that all crew members participate in regular training, including:

• Fire drills
• Abandon ship drills
• Oil spill response
• Enclosed space rescue
• Lifeboat launching
• Emergency generator operation

Modern inspections such as SIRE 2.0 place significant emphasis on crew competence, making continuous training more important than ever.

---

9. Ship Security

The captain is also responsible for implementing the Ship Security Plan in accordance with the ISPS Code.

This includes:

• Controlling visitor access
• Monitoring restricted areas
• Preventing unauthorized boarding
• Conducting security drills
• Preparing for piracy risks
• Responding to security threats

Nowadays vessels also carry security alert systems that can notify authorities in emergency situations.

---

10. Safe Navigation and Maneuvering

The captain has overall responsibility for the safe navigation of the vessel.

Although local pilots assist during port arrivals and departures, the captain remains responsible for the vessel’s safety throughout the maneuver.

Good communication between the bridge team, pilot, tugboats, and port authorities is essential.

---

11. Cargo Documentation

The captain signs numerous legal documents during cargo operations, including:

• Bills of Lading
• Cargo Manifest
• Notice of Readiness (NOR)
• Letters of Protest
• Statements of Facts
• Time Sheets

These documents have significant commercial and legal importance.

---

A Typical Day in the Life of a Ship Captain

Imagine your vessel is arriving in Rotterdam to load cargo.

The day begins around 0900 when the captain takes command on the bridge during the final approach. After contacting Vessel Traffic Services (VTS)in that case Maas Approach, the vessel is instructed to proceed to the anchorage because no berth is currently available.

Once the ship reaches the anchorage, the captain completes the End of Sea Passage Checklist and submits the Notice of Readiness (NOR) to the charterers, confirming that the vessel has arrived and is ready to load cargo.

Several hours later, the berth becomes available.

The anchor aweigh, the vessel proceeds to the pilot station, embarks the pilot, and safely berths alongside.

Cargo loading begins after all inspections and documentation are completed.

During loading, officers monitor cargo operations while the captain communicates continuously with the terminal, agents, charterers, and the shipping company.

After loading is completed, cargo calculations are verified, documents are signed, and the vessel departs for Southampton UK.

Upon arrival, the entire process is repeated for cargo discharge before the voyage is officially completed.

While this appears easy on paper, the captain spends the entire voyage making decisions, answering emails, communicating with the office, supervising operations, solving crew issues, preparing for inspections, and ensuring compliance with international regulations.

How Much Does a Ship Captain Earn?

Average monthly salaries in 2026 vary depending on vessel type, company, trading area, and experience.

Vessel Type	Average Monthly Salary
Bulk Carrier	USD 5,000–11,000
Ro-Ro Vessel	USD 6,500–10,500
Oil & Chemical Tanker	USD 10,000–15,500
LNG/LPG Carrier	USD 15,000–22,000

These figures are approximate industry averages.

---

Why Do Captain Salaries Differ So Much?

Many people wonder why captains performing the same rank receive very different salaries.

Several factors influence a captain’s earnings:

• Type of vessel
• Cargo carried
• Trading area
• Size of the vessel
• Company reputation
• Years of experience
• English proficiency
• Specialized training
• Difficulty of recruitment

For example, captains working on LNG carriers or large chemical tankers usually earn significantly more than those working on small coastal cargo vessels. This is because these ships require advanced technical knowledge, stricter safety procedures, and experience operating in highly regulated environments.

Shipping companies compete for experienced captains who have demonstrated strong leadership, excellence

Although the profession offers attractive salaries, it also carries enormous responsibility and pressure. In today’s shipping industry, captains are expected not only to navigate safely but also to manage people, comply with international regulations, communicate effectively with shore management, and make critical decisions under challenging conditions.

Behind every successful voyage is a captain who balances experience, leadership, and responsibility to ensure that both the ship and her crew arrive safely at their destination.

Learn what merchant shipping is, how commercial ships work, different vessel types, cargo operations, navigation systems, and why shipping is the backbone of global trade.

Every product we use in our daily lives has a journey behind it.

The fuel that powers our cars, the food we consume, the raw materials used to build our homes, and even the devices we use every day all depend on one of the oldest industries in human history: merchant shipping.

For thousands of years, humans have searched for the easiest, safest, and most efficient ways to transport goods from one place to another. Among all transportation methods, ships have always provided the greatest advantage: the ability to carry enormous quantities of cargo over long distances with the lowest cost and energy consumption.

Ancient civilizations already understood the power of maritime transportation. The Egyptians used boats on the Nile River thousands of years ago to transport massive stones used in the construction of pyramids. Even with primitive technology, waterways provided the most efficient method to move heavy materials.

Today, this same principle continues on a global scale.

Modern merchant ships transport approximately the majority of global trade by volume, carrying billions of tons of cargo every year across oceans. Without shipping, international trade as we know it would not exist.

A single large tanker can carry hundreds of thousands of tons of crude oil in one voyage. A large container ship can transport tens of thousands of containers connecting continents. Bulk carriers deliver raw materials that keep factories operating around the world.

Shipping is not just an industry.

Shipping is the foundation of the global economy.

---

Why Is Merchant Shipping So Important?

Many people see ships only as large vessels moving on the ocean, but their real purpose is much bigger.

A ship is essentially a floating transportation system designed to move massive amounts of cargo with maximum efficiency.

For example, a large oil tanker may carry around 300,000 tons of crude oil.

To understand this capacity:

• Density of crude oil: approximately 0.85 tons per cubic meter
• 300,000 tons of oil equals around 350,000 cubic meters
• This represents approximately 350 million liters of oil
• If one car fuel tank holds around 60 liters, this amount could theoretically fill 5,8 millions of vehicles at the same time which means can fill all tanks of cars in Los Angeles,United States.

Transporting this amount of cargo by air or road would be practically impossible and extremely expensive.

Aircraft are fast, but their carrying capacity is limited. Trucks are flexible, but they cannot compete with ships in terms of volume and cost.

A ship can travel thousands of miles carrying hundreds of thousands of tons while consuming relatively low energy per ton of cargo.

This is why maritime transportation remains the most economical and environmentally efficient method for international cargo movement.

---

What Is a Merchant Ship?

A merchant ship is a commercial vessel designed specifically to transport cargo or passengers for economic purposes.

Unlike naval vessels or private yachts, merchant ships operate as businesses. Their purpose is simple:

Carry cargo from one location to another safely, efficiently, and profitably.

Modern merchant ships are designed around one main principle:

Maximum cargo capacity with minimum operating cost.

As ships become larger, they can carry more cargo with fewer voyages, reducing the transportation cost per unit.

A simple comparison:

Instead of using your own car to transport one bag, imagine using a bus that can carry thousands of bags at the same time.

The bus requires more fuel than your car, but the cost is shared between thousands of passengers.

Ships work with the same logic.

---

How Big Are Modern Ships?

Ship sizes today are beyond what most people imagine.

The largest container ships can carry more than 20,000 TEU (Twenty-foot Equivalent Units).

A single voyage can transport:

• Cars
• Electronics
• Machinery
• Clothing
• Food products
• Industrial materials

These ships connect manufacturing centers in Asia with consumers in Europe, America, and other regions.

Large bulk carriers can transport around 200,000 tons or more of raw materials such as:

• Iron ore
• Coal
• Grain
• Fertilizers

These materials are essential for industries such as steel production, agriculture, and energy.

Oil tankers transport the energy resources that keep cities, factories, and transportation systems operating.

Without merchant ships, modern civilization would stop functioning.

---

Why Are Ships More Efficient Than Other Transportation Methods?

The biggest advantage of ships comes from physics.

Ships use buoyancy to stay afloat. The water supports a huge portion of the vessel’s weight, meaning the energy required to move cargo is much lower compared with land transportation.

A plane carrying cargo must overcome the full force of gravity throughout its flight.

A truck must overcome road friction and carry its own weight.

A ship mainly needs propulsion power to overcome water resistance.

This allows ships to transport enormous quantities of cargo with relatively low fuel consumption.

For example:

An aircraft may burn tens of tons of fuel during a flight while carrying only a limited amount of cargo.

A commercial ship may travel thousands of nautical miles carrying tens of thousands of tons of cargo with similar fuel consumption.

For an example from Hamburg to London it takes around 45 minutes by flight and total consumption of 15 tons of Jet-A1 , per ton appr. 1500 usd,same destination can take 20 hours by ship with cost of 30 tons of fuel ,per ton appr.750 usd, so flight can carry max 50 tons but vessel can carry 30.000 tons of cargo with almost same amount of consumption.

This efficiency is the reason shipping will remain the backbone of global trade for generations.

The Different Types of Merchant Ships

Because global trade involves thousands of different products, the shipping industry developed many specialized vessel types.

Each ship is designed according to the cargo it carries.

The main categories include:

• Bulk carriers
• Oil tankers
• Chemical tankers
• Container ships
• Ro-Ro vessels
• General cargo vessels
• Gas carriers
• Specialized vessels

Every vessel has a specific purpose, and choosing the correct ship type is critical for safe and economical transportation.

Bulk Carriers: The Giants Carrying the World’s Raw Materials

Bulk carriers are among the most important vessels in global trade because they transport the raw materials required for modern civilization.

Unlike container ships that carry packaged goods, bulk carriers transport cargo directly inside large cargo holds.

Typical bulk cargo includes:

• Coal
• Iron ore
• Grain
• Wheat
• Sugar
• Fertilizers
• Copper concentrate
• Aluminum products
• Scrap metal

These materials may not look valuable individually, but they are the foundation of industries worldwide.

For example:

A steel factory cannot operate without iron ore and coal. Agricultural production depends on fertilizers transported by bulk carriers. Food industries rely on grain shipments arriving from different continents.

Bulk carriers are categorized according to their size:

• Handysize: Smaller vessels designed for ports with draft limitations
• Supramax: Medium-sized vessels with flexible trading capability
• Panamax: Ships designed to fit through the original Panama Canal dimensions
• Capesize: Large vessels that transport massive quantities of raw materials
• Very Large Ore Carriers (VLOC): Specialized vessels carrying extremely large amounts of iron ore

Depending on size, age, and condition, a bulk carrier can cost anywhere from several million dollars to over 100 million dollars.

---

Oil Tankers: Transporting the World’s Energy

Oil tankers are designed to transport petroleum products from production areas to refineries and consumers.

Since oil is one of the most important energy sources in the world, tanker ships play a critical role in maintaining global energy supply.

However, not all tankers are the same.

Different cargoes and trade routes require different ship designs.

The main tanker categories include:

• VLCC
• Suezmax
• Aframax
• MR Tankers
• Chemical Tankers

---

VLCC (Very Large Crude Carrier)

VLCCs are among the largest commercial vessels ever built.

Their main purpose is transporting crude oil from oil-producing countries to large refineries.

Typical characteristics:

• Capacity: approximately 200,000–320,000 tons of cargo
• Length: around 300 meters or more
• Mainly used for long-distance international voyages

These vessels usually carry unrefined crude oil, which is later processed inside refineries to produce:

• Gasoline
• Diesel
• Jet fuel
• Lubricants
• Other petroleum products

Because of their enormous capacity, VLCCs provide one of the lowest transportation costs per ton of oil.Since the hormuz strait crisis increased daily rate of these tankers massively increased in 2026 February to May, now on the market highest rate is 400.000 usd for a day of renting price of VLCC tanker.

---

Suezmax and Aframax Tankers

Not every port can accept the largest tankers.

Many terminals have limitations regarding:

• Water depth
• Loading equipment
• Port infrastructure

For this reason, smaller tanker categories were developed.

Suezmax Tankers

The name comes from the Suez Canal.

These ships are designed to carry the maximum size allowed through the canal.

Typical capacity:

• Around 120,000–200,000 tons of cargo

They are commonly used for crude oil transportation between major oil-producing and consuming regions.

---

Aframax Tankers

Aframax vessels are smaller than Suezmax tankers.

Typical capacity:

• Around 70,000–120,000 tons

Their advantage is flexibility.

They can access more ports compared with larger vessels, making them valuable for regional oil transportation.Generally a VLCC brings cargo from UA to US and can not enter to port due to draft restriction then these tonnages go to anchorage conduct STS operation with VLCC then come to discharge in port.

---

MR Tankers: The Flexible Workhorses of Petroleum Transportation

MR stands for Medium Range tanker.

These vessels are among the most common and versatile ships in the tanker industry.

Typical capacity:

• Approximately 30,000–50,000 tons

Unlike crude oil tankers, MR tankers often transport refined petroleum products such as:

• Diesel oil
• Gasoline
• Jet fuel
• Fuel oil
• Vegetable oils
• Biofuels

Their size provides a major advantage:

They can access thousands of ports around the world where larger tankers cannot operate.

This makes them extremely valuable for charterers and cargo owners.

For example, an MR tanker can transport fuel from Europe to Africa, Asia to Europe, or South America to China.

Their flexibility makes them one of the most important ship types in modern petroleum logistics.To be honest these are the best tankers you can work on, firstly worload is less compare to bigger or smaller ones and your system is not so complex , pumps are framo and all lines on deck , less technical issues , if you like port visits and less problems with long stay compare to chemical tankers and less job including tank washing,this is the vessel you should work on.

---

Chemical Tankers: The Specialists of the Maritime Industry

Chemical tankers are some of the most technically advanced vessels in shipping.

Their purpose is transporting liquid chemicals safely across oceans.

Unlike crude oil, chemical cargoes often have:

• Higher value
• Greater risks
• More complex handling requirements

Chemical cargoes include:

• Alcohols
• Acids
• Solvents
• Fertilizer products
• Paint materials
• Additives
• Pharmaceutical chemicals
• Industrial raw materials

Examples include:

• Methanol
• Ethanol
• Styrene Monomer
• Fatty Acid Methyl Ester (FAME)
• Vegetable oils
• Various chemical derivatives

---

Why Are Chemical Tankers Smaller?

A common question is:

“If chemicals are valuable, why not transport them on huge tankers?”

The answer is efficiency.

Chemical products are usually produced in smaller quantities compared with crude oil.

A refinery may produce millions of tons of crude oil products, but specialized chemicals are often manufactured in smaller batches for specific industries.

Therefore, using a 300,000-ton tanker would be inefficient.

Chemical tankers usually range from:

• 2,000 DWT
• 10,000 DWT
• 20,000 DWT

Some chemical tankers can earn higher revenue than much larger vessels because they transport extremely valuable cargoes.

For example:

A tanker carrying 30,000 tons of fuel oil may transport cargo worth millions of dollars.

However, a chemical tanker carrying only a few thousand tons of a specialized chemical product may carry an equal or higher cargo value.

This is why chemical shipping requires advanced knowledge, strict procedures, and highly trained crews.

---

Ro-Ro Vessels: Floating Car Parks

Ro-Ro means Roll-On/Roll-Off.

These ships are designed to transport vehicles with wheels.

Instead of loading cargo using cranes, vehicles simply drive onto the vessel through large ramps.

Ro-Ro vessels carry:

• Cars
• Trucks
• Buses
• Construction machinery
• Agricultural equipment
• Military vehicles

Inside the ship are multiple vehicle decks with different heights.

Some decks are designed for:

• Passenger cars
• SUVs
• Trucks
• Heavy machinery

A large car carrier can transport thousands of vehicles during one voyage.

For example, transporting a luxury SUV internationally may generate significant revenue per vehicle, and thousands of vehicles together create a highly profitable voyage.

Because of their specialized design and complex internal structure, Ro-Ro vessels are expensive to build but essential for the global automotive industry.

---

General Cargo Vessels: The Flexible Transporters

General cargo vessels are designed to transport a wide variety of goods that do not fit into standard categories.

They may carry:

• Machinery
• Railway equipment
• Industrial components
• Project cargo
• Large construction materials

Many industries depend on these vessels because some cargoes are too large, heavy, or unusual for container transportation.

For example:

Aircraft components, including parts manufactured for major aviation companies, may be transported by specialized general cargo vessels.

Their flexibility allows them to serve ports that larger ships cannot reach.

---

Specialized Ships: When Cargo Requires a Unique Solution

The shipping industry constantly changes according to global demand.

As new industries develop, new vessel designs appear.

Examples include:

• LNG carriers for liquefied natural gas
• LPG carriers for liquefied petroleum gas
• Livestock carriers
• Fruit carriers
• Banana carriers
• Wine carriers
• Heavy-lift vessels

Every cargo has different requirements.

The ship must be designed around the cargo, not the other way around.

This is one of the reasons merchant shipping remains such a complex and fascinating industry.

---

Understanding Ship Design: How Is a Ship Built?

Although ships have different purposes, most vessels share the same fundamental components:

• Hull
• Machinery spaces
• Deck areas
• Accommodation
• Cargo spaces
• Bridge

Each part has a specific function that allows the vessel to operate safely.

The Main Structure of a Ship: Understanding How a Vessel Is Designed

A ship may look like a simple floating structure from the outside, but inside it is an extremely complex engineering system.

Every part of a vessel has a specific purpose. The design must consider:

• Cargo capacity
• Stability
• Safety
• Strength
• Fuel efficiency
• Crew living conditions
• Environmental regulations

A modern ship is not only built to float. It must survive extreme weather conditions, carry thousands of tons of cargo, operate continuously for months, and protect the lives of everyone onboard.

---

Hull: The Foundation of Every Ship

The hull is the main body and structural foundation of the vessel.

It is the part that provides:

• Buoyancy
• Structural strength
• Protection for cargo and machinery
• Hydrodynamic efficiency

Unlike a simple steel box, a ship’s hull is carefully designed with complex shapes and reinforced structures to withstand enormous forces from waves, cargo weight, and the movement of the vessel.

A ship at sea is constantly exposed to pressure.

Imagine a vessel sailing through heavy weather where waves can reach 10–12 meters in height. Every wave creates massive forces trying to bend, twist, and stress the steel structure.

For this reason, ships are constructed using special marine-grade steel with carefully calculated:

• Frames
• Longitudinal strength members
• Keels
• Bulkheads
• Reinforced areas

The keel is often described as the backbone of the ship because it provides the main longitudinal strength.

A simplified way to understand ship construction is:

First, engineers create the strongest structural foundation.

Then they build the remaining systems around it.

Just like a building needs a strong foundation before adding floors, a ship requires a strong hull before adding machinery, cargo spaces, and accommodation.

---

Machinery Space: The Power Center of the Vessel

The machinery space is where the ship’s main propulsion and supporting systems are located.

The most important equipment inside this area is the:

Main Engine

The main engine is responsible for producing the power required to move the vessel.

Unlike cars, which use relatively small engines, commercial ships use enormous marine engines designed to operate continuously for thousands of hours.

A ship engine can operate for months without stopping except for maintenance.

The required engine power depends on:

• Ship size
• Vessel type
• Required speed
• Operating conditions

For example:

A large container ship prioritizes speed because schedule reliability is critical.

Therefore, it may have a very powerful engine producing tens of thousands of horsepower.For better understanding Maersk Triple E class megaships have 85.000 horsepower engine.

A chemical tanker may prioritize fuel efficiency rather than speed.

For this type of vessel, a smaller but highly efficient engine may be more suitable.

---

Two-Stroke and Four-Stroke Marine Engines

Commercial ships mainly use two types of diesel engines:

Four-Stroke Engines

Four-stroke engines operate using a similar principle to automobile engines.

The cycle consists of:

1. Intake
2. Compression
3. Power
4. Exhaust

They are commonly used for:

• Generators
• Smaller vessels
• Auxiliary machinery

---

Two-Stroke Engines

Most large commercial vessels use two-stroke engines.

These engines are completely different from car engines.

Advantages include:

• Extremely high efficiency
• Large power output
• Long operational life
• Ability to directly drive the propeller

The piston movement is slower but much more powerful.

A modern marine engine can have:

• Pistons taller than a person
• Turbochargers larger than a small vehicle
• Individual components weighing several tons

These engines are specifically designed for moving enormous ships through difficult ocean conditions.

---

How Does a Ship Actually Move?

Producing engine power is only the beginning.

The engine must transfer this power into movement.

This happens through the propulsion system.

The basic process:

Main Engine → Shaft → Propeller → Thrust → Ship Movement

The engine rotates a long shaft connected to the propeller.

The propeller pushes water backward.

According to Newton’s Third Law:

Every action has an equal and opposite reaction.

The water pushed backward creates a force that moves the ship forward.

---

Types of Ship Propellers

Commercial vessels mainly use two types of propellers.

Fixed Pitch Propeller (FPP)

A fixed pitch propeller has permanent blade angles.

To change speed:

• Engine RPM increases
• Propeller rotates faster
• Ship moves faster

This system is simple, reliable, and commonly used.

---

Controllable Pitch Propeller (CPP)

A controllable pitch propeller allows the blade angle to change.

The engine may maintain a constant RPM while the propeller adjusts the blade position.

Advantages:

• Better maneuverability
• Faster response
• Improved control during port operations

CPP systems are common on vessels requiring frequent maneuvering.

---

Generators: The Ship’s Electrical Supply

The main engine moves the ship, but many other systems require electricity.

This power is produced by generators.

Generators supply electricity for:

• Accommodation
• Navigation equipment
• Cargo pumps
• Lighting
• Communication systems
• Refrigeration
• Safety equipment

A ship is basically a floating city.

Even when the vessel is not moving, electrical systems must continue operating.

---

Boilers: Producing Heat for Ship Operations

Many ships also have boilers.

A boiler produces steam used for various purposes, especially onboard tankers.

Applications include:

• Heating cargo
• Heating fuel oil
• Hot water production
• Machinery systems

Some cargoes become too viscous at low temperatures.

For example, heavy fuel oil may require heating before it can be pumped or burned.

Without heating systems, cargo operations could become impossible.

---

Rudder: Controlling the Direction of the Ship

A ship needs a steering system to change direction.

This is the role of the rudder.

The rudder is located behind the propeller.

When the rudder changes position:

1. Water flow from the propeller changes direction
2. A force is created on the rudder
3. The ship changes course

However, large ships do not turn like cars.

Due to their enormous size and momentum, turning a vessel requires planning and time.

---

Bow Thruster: Helping During Maneuvering

Large ships have limited maneuverability at low speed.

To improve control in ports, many vessels use bow thrusters.

A bow thruster is a small propeller installed at the forward part of the ship.

It helps:

• Move the bow sideways
• Assist during berthing
• Improve maneuvering ability

However, bow thrusters are effective only at low speeds.

They are mainly used during port operations and not during normal ocean passages.

---

Accommodation: Life at Sea

The accommodation area is where the crew lives.

Modern vessels provide:

• Private cabins
• Officer and crew mess rooms
• Recreation areas
• Gym facilities
• Internet access
• Common spaces

Life onboard can last several months, so crew welfare is extremely important.

Unlike older ships where several people shared cabins, many modern vessels provide single-person accommodation.

This gives seafarers:

• Privacy
• Rest after working hours
• Personal space during long voyages

Although life at sea is challenging, modern ships provide much better living conditions compared with previous generations.

---

The Bridge: The Ship’s Command Center

The bridge is the navigation and control center of the vessel.

It is similar to the cockpit of an aircraft.

From the bridge, officers:

• Navigate the vessel
• Monitor traffic
• Communicate with other ships
• Plan routes
• Control speed
• Conduct maneuvering operations

The bridge contains advanced navigation systems that allow ships to safely cross oceans.

Modern Ship Navigation Systems: How Ships Find Their Way Across the Oceans

A ship may be thousands of miles away from land, surrounded only by water, with no visible landmarks to guide the crew.

So how does a vessel safely travel from one continent to another?

The answer is a combination of advanced navigation technology, professional knowledge, and careful planning.

Modern ships are equipped with highly sophisticated systems that allow officers to monitor:

• The vessel’s position
• Surrounding traffic
• Water depth
• Weather conditions
• Planned route
• Potential dangers

However, technology is only a tool.

A safe voyage still depends on the experience, decision-making, and attention of the crew.

The main navigation systems onboard commercial ships include:

• ECDIS
• Radar
• AIS
• Echo Sounder
• Gyro Compass
• Magnetic Compass
• Autopilot

---

ECDIS: The Electronic Chart System

ECDIS stands for:

Electronic Chart Display and Information System

It is one of the most important navigation systems onboard modern vessels.

Before electronic navigation, seafarers used traditional paper charts.

These charts required constant manual updates whenever there was:

• A change in navigation warnings
• New underwater hazards
• Buoy position changes
• Port information updates

Officers had to apply corrections manually using official publications such as Notices to Mariners.

Today, ECDIS has transformed navigation.

Electronic charts can be updated digitally, allowing officers to receive the latest information quickly and accurately.

---

What Can ECDIS Show?

ECDIS provides essential information such as:

• Ship position
• Planned route
• Safety depth
• Water depth
• Navigation warnings
• Restricted areas
• Buoy positions
• Traffic information

Before every voyage, officers prepare a detailed passage plan using ECDIS.

This plan includes:

• Departure point
• Waypoints
• Courses
• Safety margins
• Arrival route

The system continuously monitors the ship’s position and warns the crew if the vessel approaches danger.

For example:

If a vessel accidentally approaches shallow water or crosses a restricted area, ECDIS can immediately provide an alarm.

This makes navigation safer and more efficient.

---

Radar: The Eyes of the Ship

Radar is one of the oldest but most important navigation systems onboard.

The word radar comes from:

Radio Detection and Ranging

Radar allows the crew to detect objects even when human vision cannot.

This is especially important during:

• Night operations
• Fog
• Heavy rain
• Poor visibility
• Congested waters

Radar sends electromagnetic waves toward the surrounding area.

When these waves hit an object, they return to the radar antenna.

By calculating the return time, the system determines:

• Distance
• Direction
• Movement of targets

---

What Can Radar Detect?

Radar can identify:

• Other ships
• Land formations
• Islands
• Buoys
• Floating objects

With correct settings, radar can even detect very small targets.

In calm conditions, experienced operators may observe small echoes such as birds or marine life.

However, radar interpretation requires experience.

Poor settings or incorrect understanding can create dangerous situations.

The officer must understand:

• Weather effects
• Sea clutter
• Blind zones
• Target movement

Radar is powerful, but human judgment remains essential.

---

AIS: The Identity System of Ships

AIS stands for:

Automatic Identification System

AIS allows ships to automatically exchange information with each other and with shore stations.

Every commercial vessel transmits important details, including:

• Ship name
• IMO number
• Position
• Speed
• Course
• Destination
• Vessel type
• Draft information

This system helps ships understand the movements of surrounding vessels.

For example:

If two ships are approaching each other, officers can see:

• Which vessel is changing course
• The expected closest distance
• The other ship’s destination
• The vessel’s identity

AIS greatly improves situational awareness.

However, AIS is not a replacement for radar.

A vessel may have:

• AIS turned off
• Incorrect information entered
• Technical problems

Therefore, officers always use AIS together with radar and visual observations.

---

Echo Sounder: Measuring the Depth Below the Ship

A ship cannot safely navigate without knowing the depth of water beneath it.

This is the purpose of the echo sounder.

The system works similarly to how dolphins use sound waves.

A sensor located under the vessel sends a sound pulse toward the seabed.

The pulse travels downward, hits the bottom, and returns.

By measuring the time required for the signal to return, the system calculates water depth.

---

Why Is Depth Measurement Important?

Large vessels may have drafts of more than 10 meters.

In shallow waters, a small error in depth calculation can create a grounding risk.

Echo sounders are especially important during:

• Port approaches
• Channel navigation
• Anchorage operations
• Shallow water passages

Modern systems continuously display depth information on the bridge.

---

Gyro Compass: The True Direction Finder

A compass is essential because a ship must know its direction at all times.

Modern ships mainly use gyro compasses.

A gyro compass provides:

• True north reference
• Accurate heading information
• Reliable navigation data

Unlike a magnetic compass, a gyro compass is not affected by Earth’s magnetic field.

This makes it more accurate, especially for large steel vessels.

The gyro compass provides information to:

• ECDIS
• Radar
• Autopilot
• Other navigation systems

---

Magnetic Compass: The Emergency Backup

Although modern vessels use gyro compasses, every ship still carries a magnetic compass.

Why?

Because safety systems require redundancy.

If there is a major electrical failure, the magnetic compass can provide a basic heading reference.

It works using Earth’s magnetic field and does not require electrical power.

Simple systems can become lifesaving during emergencies.

---

Autopilot: Automatic Steering System

Imagine steering a ship manually for several days during an ocean voyage.

It would be extremely difficult and exhausting.

This is why ships use autopilot systems.

The officer selects a desired course.

The autopilot automatically controls the steering system to maintain that heading.

Advantages include:

• Reduced workload
• Improved fuel efficiency
• More consistent steering
• Better voyage management

However, autopilot is not completely independent.

Officers must always monitor:

• Traffic conditions
• Weather
• System performance

In restricted waters, heavy traffic, or port approaches, ships are usually manually controlled by officers.

---

The Human Element in Navigation

Although modern ships have advanced technology, navigation is not simply pressing buttons.

A professional navigator must understand:

• Weather patterns
• Ocean currents
• Ship behavior
• Collision regulations
• Equipment limitations
• Emergency procedures

A computer can calculate a route.

But a skilled officer decides whether that route is safe.

Technology supports seafarers.

It does not replace them.

The Purpose of Every Ship: Carrying Cargo

All these systems exist for one main reason:

To transport cargo safely from one destination to another.

A ship without cargo capability cannot generate revenue.

Cargo operations are therefore the heart of merchant shipping.

Especially on tanker vessels, cargo handling requires extreme attention because ships may carry thousands of tons of:

• Flammable liquids
• Toxic chemicals
• Petroleum products
• Dangerous substances

A small mistake can cause:

• Pollution
• Fire
• Explosion
• Loss of life
• Financial damage

For this reason, cargo operations are among the most important responsibilities onboard.

Tanker Cargo Operations: How Thousands of Tons of Liquid Cargo Are Controlled Safely

Among all merchant ships, tankers require some of the most complex cargo operations.

A tanker is not simply a vessel that carries liquid inside tanks.

It is a highly specialized system designed to transport dangerous and valuable cargo safely while protecting:

• The crew
• The vessel
• The environment
• The cargo itself

A modern oil or chemical tanker may carry tens of thousands of tons of petroleum products or chemicals.

Imagine having 30,000 tons of flammable liquid inside a vessel surrounded by nothing but ocean.

The responsibility is enormous.

Every operation must be carefully planned and controlled.

---

The Cargo Planning Process

Before a tanker starts a voyage, the vessel receives detailed voyage instructions from the company or charterer.

These instructions include:

• Cargo type
• Cargo quantity
• Density
• Loading temperature
• Discharge port
• Special requirements
• Compatibility information

The vessel’s officers must analyze this information and confirm whether the ship can safely perform the operation.

Before loading begins, the cargo officer prepares a:

Cargo Plan

The cargo plan determines:

• Which tanks will be used
• Cargo distribution
• Loading sequence
• Maximum filling levels
• Stability condition
• Stress limitations

The plan must consider the ship’s:

• Draft
• Trim
• Stability
• Structural strength

A tanker cannot simply fill tanks randomly.

Every action affects the vessel.

---

Loading Operation: Bringing Cargo Onboard

When the ship arrives at the loading terminal, communication begins between:

• Ship officers
• Terminal operators
• Surveyors
• Cargo representatives

Before cargo transfer starts, both sides agree on a:

Ship-Shore Safety Checklist

This confirms important safety points such as:

• Correct cargo connection
• Emergency shutdown procedures
• Communication methods
• Fire protection readiness
• Mooring safety
• Pollution prevention measures

Only after all safety requirements are completed can loading begin.

---

Cargo Lines and Loading Pressure

Cargo transfer happens through large pipelines connected between the vessel and terminal.

The loading rate depends on:

• Pipe diameter
• Terminal capacity
• Ship system limitations
• Tank pressure

The ship must inform the terminal about its maximum allowable loading rate.

If cargo enters too quickly:

• Pressure can increase
• Cargo lines may fail
• Tank ventilation systems may become overloaded

A simple example:

Imagine filling a closed bottle with liquid while air is trapped inside.

The trapped air creates pressure.

A cargo tank works with the same principle.

If pressure is not controlled, dangerous situations can occur.

---

Cargo Tanks: The Heart of a Tanker

Unlike bulk carriers that use cargo holds, tankers use enclosed cargo tanks.

These tanks are specially designed to transport liquid products safely.

Depending on the vessel type, tanks may have:

Coated Steel Tanks

Many oil and chemical tankers use special epoxy coatings.

These coatings:

• Protect the steel
• Prevent contamination
• Resist chemical reactions

Stainless Steel Tanks

Chemical tankers carrying highly aggressive cargoes may use stainless steel tanks.

Advantages:

• High corrosion resistance
• Better cargo compatibility
• Longer lifetime

The tank material depends on the cargo requirements.

---

Tank Cleaning: Preparing for the Next Cargo

One of the most important tanker operations is tank cleaning.

A tanker may carry one cargo today and a completely different cargo on the next voyage.

For example:

A vessel may transport fuel oil and later need to load vegetable oil or chemicals.

The cargo tanks must be cleaned according to strict procedures.

Tank cleaning may involve:

• Fresh water washing
• Sea water washing
• Chemical cleaning
• Ventilation
• Drying
• Inspection

Modern tankers use fixed tank washing machines installed inside tanks.

These machines rotate using water pressure and clean internal surfaces.

The cleaning standard depends on the next cargo requirement.

Some sensitive cargoes require extremely high cleanliness standards.

---

Cargo Monitoring Systems

A tanker cannot depend on manual measurement for thousands of tons of cargo.

Imagine trying to manually calculate:

• 10 cargo tanks
• 30,000 tons of liquid
• Different temperatures
• Changing levels

This would be impossible.

Therefore, tankers use advanced monitoring systems.

---

Tank Radar System

Tank radar is an automatic level measurement system.

It uses radar technology installed on the top of cargo tanks.

The system sends signals toward the cargo surface.

By measuring the return signal, it calculates:

• Cargo level
• Volume
• Quantity

The information is displayed in the:

Cargo Control Room (CCR)

From the CCR, officers can monitor:

• Tank levels
• Cargo temperatures
• Tank pressure
• Loading progress
• Discharging progress

---

Cargo Temperature Monitoring

Temperature is extremely important for tanker operations.

Some cargoes require specific temperatures because:

• They become too thick when cold
• They may react at high temperatures
• Their quality can change

Cargo tanks usually have multiple temperature sensors:

• Bottom level
• Middle level
• Top level

This allows officers to understand the complete condition of the cargo.

---

Cargo Tank Pressure Control

Every cargo tank has a ventilation system.

Why?

Because liquid cargo creates vapor.

During loading:

• Liquid enters the tank
• Vapor space becomes smaller
• Pressure increases

During discharge:

• Liquid leaves the tank
• Pressure decreases

Without proper pressure control:

• Tank deformation
• Equipment damage
• Cargo release
• Explosion risk

could occur.

Tank pressure is continuously monitored.

---

Inert Gas System: Preventing Fire and Explosion

One of the most important safety systems on oil tankers is the:

Inert Gas System (IGS)

The purpose of inert gas is simple:

Reduce oxygen inside cargo tanks to prevent combustion.

A fire requires three elements:

1. Fuel
2. Oxygen
3. Ignition source

This is known as the fire triangle.

Remove oxygen, and combustion becomes extremely difficult.

---

How Does Inert Gas Work?

The inert gas system produces gas with very low oxygen content.

On modern tankers, the oxygen concentration of inert gas is approximately:

Below 5%

In some systems, nitrogen generation can reduce oxygen levels even further.

The gas is sent through:

• Inert gas main line
• Deck water seal
• Isolation valves
• Tank distribution system

into cargo tanks.

This creates a safe atmosphere above the cargo.

---

Why Is Oxygen Control So Important?

Petroleum vapors can become extremely dangerous when mixed with air.

If oxygen concentration reaches a flammable range and an ignition source appears, an explosion can occur.

By maintaining low oxygen levels:

• Explosion risk decreases
• Cargo operations become safer
• Tank atmosphere remains controlled

This system is especially important during:

• Loading
• Discharging
• Tank cleaning
• Voyage periods

---

Discharging Cargo: Delivering the Product

After arriving at the discharge port, the process is carefully repeated.

The vessel communicates with the terminal and confirms:

• Discharge plan
• Cargo quantity
• Pumping rate
• Safety procedures

Tankers usually use their own cargo pumps.

These pumps are extremely powerful and designed to transfer thousands of tons of liquid efficiently.

Cargo pumps can be driven by:

• Electric motors
• Hydraulic systems

After completing discharge:

• Tanks are checked
• Cargo figures are calculated
• Documentation is completed
• The vessel prepares for the next voyage

---

Ballast Operations: Keeping the Ship Safe Without Cargo

A ship cannot operate safely without proper stability.

When a tanker is fully loaded, cargo provides weight and keeps the vessel correctly positioned in water.

But what happens when the cargo is discharged?

The ship becomes lighter.

To maintain safe navigation, ships take seawater into special tanks called:

Ballast Tanks

Ballast water helps control:

• Stability
• Draft
• Trim
• Propeller immersion
• Structural stress

A large tanker may carry thousands of tons of ballast water.

Ballast Operations, Stability, and Environmental Protection: How Ships Stay Safe at Sea

A ship is designed to operate in many different conditions.

It may sail fully loaded with cargo, partially loaded, or completely empty.

However, a vessel cannot simply float safely without proper weight distribution.

One of the most important systems that allows ships to remain stable is the ballast system.

Ballast operations are a fundamental part of ship management because every change in weight affects:

• Stability
• Draft
• Trim
• Structural strength
• Propeller efficiency
• Safety during navigation

---

What Is Ballast Water?

Ballast water is seawater taken onboard into dedicated tanks to improve the vessel’s condition when cargo weight is insufficient.

When a tanker discharges its cargo, it loses thousands of tons of weight.

Without ballast:

• The ship may rise too high out of the water
• The propeller may not be fully submerged
• Stability may become unsafe
• The vessel may experience excessive movement in waves

By taking ballast water, the ship increases its draft and returns to a safer operating condition.

---

Where Are Ballast Tanks Located?

Ballast tanks are specially designed spaces separated from cargo areas.

They are usually located:

• Along the sides of cargo tanks
• Below cargo tanks
• In forward and aft sections

Many tankers use a design called:

Segregated Ballast Tanks (SBT)

This means ballast water has completely separate tanks from cargo tanks.

The advantage is:

• No contact between ballast water and oil cargo
• Reduced pollution risk
• Safer environmental operation

---

Why Is Stability So Important?

Every action onboard changes the ship’s balance.

Loading cargo, discharging ballast, transferring fuel, or moving liquids between tanks can affect:

• List (sideways inclination)
• Trim (difference between forward and aft draft)
• Stability
• Hull stress

A ship is not a rigid object.

It is a flexible steel structure floating in water.

Improper weight distribution can create excessive forces on the hull.

Over time, this can contribute to:

• Structural cracks
• Leakage
• Damage to tanks
• Reduced vessel lifetime

Officers continuously monitor stability calculations during cargo and ballast operations.

---

Understanding Ship Stress

Large vessels experience different forces while sailing.

The most important structural forces include:

Bending Moments

A ship can bend because of uneven wave support.

Imagine a ship sitting on two waves:

• The bow and stern supported by waves
• The middle section unsupported

This creates bending stress.

The opposite situation can also occur when the middle of the vessel is supported by a wave.

---

Shear Forces

Shear forces occur when different sections of the ship experience different loads.

Incorrect cargo distribution can increase these forces.

For this reason, cargo loading is not only about filling tanks.

It is about maintaining the correct balance.

---

Ballast Water and Marine Pollution

Ballast water creates another environmental challenge.

Imagine a ship loading ballast water from one region and later releasing it thousands of miles away.

That water may contain:

• Small organisms
• Bacteria
• Marine species
• Parasites
• Microorganisms

When introduced into a different ecosystem, these organisms can become invasive species.

They may:

• Damage local marine life
• Compete with native species
• Create ecological problems

Because of this risk, international regulations require ships to treat ballast water before discharge.

---

Ballast Water Treatment Systems (BWTS)

Modern ships are equipped with Ballast Water Treatment Systems.

The purpose is:

Remove or neutralize harmful organisms before ballast water is released.

There are several treatment technologies.

The most common systems include:

• UV treatment systems
• Electrolysis-based systems

---

UV Ballast Water Treatment Systems

The first method uses:

Ultraviolet Radiation

The process:

1. Seawater enters the ship through the sea chest
2. Filters remove larger particles
3. Water passes through UV chambers
4. UV radiation damages microorganisms

UV treatment does not add chemicals into the water.

Advantages:

• Environmentally friendly
• No chemical storage required
• Simple operation

UV systems can eliminate a very high percentage of microorganisms when operated correctly.

---

Electrolysis-Based Ballast Water Treatment Systems

Another common method uses electrolysis.

The process:

1. Seawater passes through filters
2. Electrolysis creates active substances
3. These substances destroy microorganisms
4. Treated water enters ballast tanks

The principle is similar to how chlorine is used to disinfect drinking water.

Advantages:

• Effective against many organisms
• Suitable for large volumes of water
• Provides strong treatment capability

However, the system requires careful monitoring because chemical levels must remain within approved limits.

---

The Importance of Environmental Regulations

Modern shipping is heavily regulated.

The industry must balance:

• Economic efficiency
• Safety
• Environmental protection

International regulations cover:

• Ballast water management
• Oil pollution prevention
• Air emissions
• Garbage disposal
• Cargo handling

Shipping has changed significantly compared with previous decades.

Modern vessels are designed not only to transport cargo but also to minimize their impact on the environment.

---

Ship Safety Systems: Protecting Lives at Sea

Safety is the highest priority onboard every commercial vessel.

Whether the ship is:

• An oil tanker
• Chemical tanker
• Container ship
• Bulk carrier
• Ro-Ro vessel

every crew member must be prepared for emergencies.

A ship is a self-contained workplace operating far from immediate assistance.

If an emergency occurs at sea, help may take hours or even days to arrive.

Therefore, ships must be capable of responding independently.

---

Why Are Safety Systems So Important?

A vessel contains many potential hazards:

• Large machinery
• High temperatures
• Electrical systems
• Heavy equipment
• Fuel
• Chemicals
• Dangerous cargo

Possible emergencies include:

• Fire
• Explosion
• Flooding
• Collision
• Grounding
• Machinery failure
• Man overboard
• Abandon ship situations

International maritime regulations require ships to carry approved safety equipment and conduct regular emergency drills.

---

Fire Safety Systems Onboard

Fire is one of the greatest risks at sea.

A ship contains many sources of ignition:

• Engines
• Electrical equipment
• Fuel systems
• Hot surfaces

For this reason, ships use multiple layers of fire protection.

These include:

• Fire detection systems
• Fire alarms
• Fire pumps
• Fire hoses
• Fixed firefighting systems
• Emergency shutdown systems

The objective is not only to extinguish fires but to prevent them from spreading.

---

Life-Saving Appliances

Because ships operate far from land, every vessel must have equipment to protect human life during emergencies.

Examples include:

Lifeboats

Designed to evacuate crew if the ship cannot remain afloat.

Life Rafts

Inflatable survival equipment used during abandonment.

Immersion Suits

Protect people from cold water exposure.

Life Jackets

Provide flotation and survival support.

Regular inspections and drills ensure crew members know how to use this equipment.

Advanced Ship Safety Systems: How Modern Ships Protect Lives During Emergencies

A ship at sea is isolated from immediate assistance.

Unlike a building on land, where firefighters, hospitals, and emergency services may arrive within minutes, a vessel may be hundreds of nautical miles away from the nearest support.

For this reason, ships must be prepared to handle emergencies independently.

Modern commercial vessels use a combination of:

• Communication systems
• Fire protection systems
• Emergency equipment
• Life-saving appliances
• Crew training and procedures

The goal is simple:

Prevent accidents whenever possible, and survive if an emergency occurs.

---

GMDSS: The Global Maritime Distress and Safety System

One of the most important safety systems onboard is:

GMDSS

Global Maritime Distress and Safety System

GMDSS is an internationally recognized communication system designed to ensure that ships can send and receive emergency information anywhere in the world.

Before GMDSS, ships mainly depended on traditional radio communication and visual signals.

Today, modern technology allows vessels to quickly communicate with:

• Other ships
• Coastal stations
• Rescue coordination centers
• Company offices
• Authorities

---

How Does GMDSS Work?

GMDSS uses several communication technologies, including:

• Satellite communication systems
• VHF radio
• MF/HF radio
• Emergency position transmitters
• Digital selective calling systems

Each system has a specific purpose.

---

Satellite Communication

Satellite systems allow ships to communicate even when they are far from land.

They can transmit:

• Distress messages
• Safety information
• Weather updates
• Operational communication

For example, if a vessel experiences a serious emergency in the middle of the ocean, satellite communication can immediately send information about:

• Ship identity
• Position
• Nature of emergency
• Required assistance

---

VHF Radio Communication

VHF radio is one of the most commonly used communication systems onboard.

It is mainly used for:

• Ship-to-ship communication
• Port communication
• Pilot communication
• Emergency situations

VHF has limited range compared with satellite systems, but it is essential during coastal navigation and port operations.

---

MF/HF Radio Systems

MF and HF radios provide longer-range communication.

They are especially useful in areas where satellite communication may not be available.

These systems allow vessels to communicate over very large distances.

---

Emergency Position Indicating Radio Beacon (EPIRB)

The EPIRB is a critical emergency device.

If a ship has to abandon the vessel, the EPIRB can automatically transmit:

• Ship identity
• Emergency signal
• Position information

Rescue authorities can use this information to locate survivors.

---

Search and Rescue Transponders (SART)

SART devices help rescue teams locate survival craft.

When activated:

• It responds to radar signals
• Creates a visible indication on rescue radar screens

This helps rescuers find:

• Lifeboats
• Life rafts
• Survivors

during difficult conditions.

---

Fire Protection Systems Onboard

Fire is one of the most dangerous emergencies on any ship.

A vessel contains many possible sources of fire:

• Fuel
• Lubricating oil
• Electrical equipment
• Machinery
• Cargo vapors

Especially on oil and chemical tankers, fire prevention is extremely important because cargo may be:

• Flammable
• Toxic
• Explosive

---

Fire Detection Systems

Modern ships use automatic fire detection systems.

These systems monitor areas such as:

• Engine rooms
• Accommodation
• Cargo pump rooms
• Storage spaces

Sensors detect:

• Smoke
• Heat
• Flame

When abnormal conditions are detected, alarms are activated immediately.

---

Fixed Firefighting Systems

Some areas require special firefighting systems because normal water hoses are not suitable.

Examples include:

CO₂ Firefighting System

Used mainly in machinery spaces.

Carbon dioxide removes oxygen from the fire area, stopping combustion.

However, because CO₂ is dangerous to humans, strict procedures must be followed before activation.

---

Foam Systems

Foam is commonly used for:

• Oil fires
• Fuel fires
• Cargo deck protection

Foam creates a layer that separates fuel from oxygen.

---

Water Mist Systems

Water mist systems use very small water droplets.

Advantages:

• Rapid cooling
• Lower water consumption
• Effective heat absorption

---

Emergency Shutdown Systems

On tankers, emergency shutdown systems are extremely important.

During dangerous situations, cargo operations can be stopped immediately.

Examples:

• Closing cargo valves
• Stopping pumps
• Isolating systems

The purpose is to prevent a small problem from becoming a major disaster.

---

Abandon Ship Procedures

The decision to abandon a ship is one of the most serious decisions at sea.

A vessel is abandoned only when remaining onboard becomes more dangerous than leaving.

Possible reasons include:

• Uncontrollable fire
• Severe flooding
• Structural failure
• Sinking risk

Every crew member must know:

• Emergency signals
• Muster station location
• Lifeboat procedures
• Personal duties

---

Lifeboats: The Last Line of Survival

Lifeboats are designed to keep people alive after leaving the vessel.

Modern lifeboats include:

• Engines
• Navigation equipment
• Emergency supplies
• Food and water
• Communication equipment
• Protection from weather

They are regularly inspected and tested.

Crew members perform drills to ensure everyone understands their responsibilities.

---

Man Overboard Safety

A person falling into the sea is one of the most urgent emergencies onboard.

Immediate actions include:

• Raising alarm
• Throwing lifebuoys
• Marking the person’s position
• Turning the vessel
• Coordinating rescue operations

Time is critical because survival depends on:

• Water temperature
• Weather conditions
• Visibility
• Response speed

---

Emergency Drills: Training Saves Lives

Equipment alone cannot guarantee safety.

People must know how to use it.

Therefore, ships conduct regular drills, including:

• Fire drills
• Abandon ship drills
• Man overboard exercises
• Security drills

During these exercises, crew members practice:

• Communication
• Equipment use
• Emergency roles
• Decision-making

A trained crew reacts faster and makes better decisions during real emergencies.

---

The Human Factor: The Most Important Safety System

Despite advanced technology, the most important safety system onboard is still:

The human being.

A modern ship can have:

• Powerful engines
• Advanced navigation
• Automated systems
• Emergency equipment

But poor decisions can still create dangerous situations.

Professional seafarers must combine:

• Knowledge
• Experience
• Discipline
• Teamwork
• Continuous learning

Safety culture is built by every person onboard.

---

Life at Sea: More Than Just a Job

Merchant shipping is not only about machines and cargo.

It is also about people.

Thousands of seafarers around the world spend months away from home to keep global trade moving.

They operate ships through:

• Storms
• Long voyages
• Difficult conditions
• Remote areas

Behind every product transported around the world, there are crews working silently at sea.

---

Final Thoughts: Why Merchant Shipping Will Always Matter

Merchant shipping is one of humanity’s oldest industries, but it remains one of the most important.

From ancient boats transporting stones along rivers to modern vessels carrying hundreds of thousands of tons across oceans, the purpose has remained the same:

Move goods safely and efficiently from one place to another.

Ships connect countries, support economies, provide energy, transport food, and supply industries.

Without merchant shipping:

• Factories would stop
• Energy supplies would decrease
• International trade would collapse

The ocean is not an empty space between continents.

It is the highway of global civilization.

With more than a decade of experience working at sea, my goal is to explain this world from the inside — beyond the images shown in the news and movies.

Here, we look at maritime reality.
