What Are the Checks to Be Performed If the Lifeboat Engine Is Not Starting?

Introduction: The Importance of Lifeboat Engine Checks at Sea

Out at sea, safety is always the top priority for every seafarer. Whether you’re navigating through clear, calm waters or stormy weather, knowing that your lifeboat engine is in top working condition brings much-needed peace of mind. But what happens if you run into a situation where the lifeboat engine just won’t start? Panic is not an option—quick thinking and the right troubleshooting steps are essential.

Lifeboat engines are a lifeline during maritime emergencies. That’s why the International Maritime Organization (IMO) and flag states require regular inspection and testing according to SOLAS regulations. As a seafarer, being familiar with lifeboat engine trouble is a must; even minor oversights can put your crew’s safety at risk. In this article, we’ll break down what to do when your lifeboat engine refuses to start, using simple, real-life examples and shipping know-how.

Why Might a Lifeboat Engine Refuse to Start?

Let’s face it—engines are mechanical beasts, and various issues can come up if maintenance is skipped or if they just haven’t been used in a while. Lifeboat engines are designed to be robust, but common reasons for failure include simple oversights (like empty fuel tanks) to more complex mechanical or electrical problems.

Here are major culprits:

• Lack of fuel or fuel contamination
• Air in the fuel system
• Battery-related issues
• Seized engine or moving parts
• Faults in starting systems (manual or electrical)
• Clogged filters
• Improper lube oil levels
• Faulty engine controls or linkages

But how can we pinpoint the cause—and more importantly, fix it?

What Checks Should a Seafarer Perform? – Step by Step Troubleshooting

1. Initial Safety Precautions

Before diving into any checks, always think safety first.

• Inform your duty officer about the issue.
• Wear appropriate PPE—lifeboat areas can have sharp edges, hot surfaces, and moving parts.
• Ensure the lifeboat is secure in its davit or cradle.

2. Checking Fuel Supply

It may sound simple, but an empty or contaminated fuel tank is one of the most common reasons for engine trouble.

• Check that the fuel tank has enough fuel. Top up if necessary.
• Inspect the fuel shut-off valve—it must be open.
• Look for any visible fuel leaks in the piping or connections.
• If the fuel looks dirty or milky, there might be water contamination. Drain and refill with clean fuel if so.

3. Bleeding the Fuel System

Did someone recently change the fuel filter? If so, there could be air trapped in the fuel lines.

• Use the fuel primer pump (if fitted) to remove air.
• Open the injector bleeding screws and pump until fuel flows clear—this removes air bubbles that prevent starting.

4. Battery and Electrical System Checks (if fitted)

Most modern lifeboat engines are started electrically, though some still use hand cranks.

• Check that the starter battery voltage and charge is sufficient (usually at least 12V or 24V, as per the engine manual).
• Inspect battery terminals for corrosion or loose connections.
• Ensure the starting switch and cables are intact.
• If the starter motor clicks but does not turn, the battery may be weak. Try charging or replacing the battery.

5. Testing the Manual Starting System (Hand Crank or Hydraulic Start)

If the electric starter isn’t working or the boat uses manual start:

• Ensure the decompression lever is in the correct position—see the engine’s instructions.
• Try gently moving the hand crank; if it’s jammed, don’t force it as internal damage may occur.

6. Lube Oil Level and Condition

An engine low on oil can seize or refuse to turn over.

• Check the dipstick for correct lube oil level.
• If the oil is very dirty, milky, or smells burnt, consider an oil change before trying to start.

7. Cooling Water Supply

Most lifeboat engines are cooled by seawater once running, but some have a header tank.

• Check that there is sufficient coolant or water in the header tank (if fitted).
• Open all relevant inlet and outlet valves as per operational procedures.

8. Air Filter and Breather Check

A choked air filter can suffocate the engine.

• Remove and inspect the air filter. Clean or replace if dirty or blocked.
• Check for obstructions in air intake pipes.

9. Engine Moving Parts and Controls

Seized moving parts can be another reason for failure.

• Check that the throttle linkage, gear lever, and stop lever are all in neutral/start positions.
• Try rotating the crankshaft by hand (if possible), to confirm nothing is jammed inside the engine.

10. Examine Fuel and Oil Filters

Clogged filters can starve the engine of fuel or lubrication.

• Check both fuel and oil filters—replace if they look dirty or clogged.

11. Follow the Engine Start-Up Procedure

Every lifeboat engine comes with a start-up checklist:

• Put all control levers in correct positions (e.g., throttle at about one-third open).
• Pronounce the area clear, call out “Starting!” per your shipboard procedure.
• Attempt to start using primary method (electric or manual).

If it starts, monitor for irregular noise, vibrations, or leaks.

12. Further Checks – When All Else Fails

If, after going through the above, the engine still doesn’t start:

• Inspect the injector—there could be a blockage or fault.
• Check the compression by feeling for resistance during hand cranking.
• Listen for any strange noises, which could indicate internal damage.
• If available, refer to the lifeboat engine manual for specific troubleshooting.
• Report to the vessel’s technical superintendent or contact shore support.

When and How Should Checks Be Performed?

Regular checks, not just in emergencies, are crucial for ensuring the lifeboat engine’s readiness. According to IMO standards, lifeboat engines should be tested weekly with the boat launched as per manufacturer requirements. Additionally, checks must be included in every planned maintenance schedule onboard.

Here’s a practical schedule:

• Weekly: Start and run the engine for at least 3 minutes.
• Monthly: Carry out full checks and run under load if possible.
• Before Port State Control (PSC) inspections or drills: Perform all basic readiness checks.

Always document every check in the ship’s logbook—as this is essential for compliance and safety records.

Best Practices and Maintenance Tips

Let’s turn to some practical advice from seafarers:

• Use only approved fuel and lube oil suitable for lifeboat engines.
• Replace filters and fluids according to manufacturer recommendations or when visually dirty.
• Keep batteries fully charged. Some ship types provide an independent charger for the lifeboat battery—ensure it’s working!
• Train all crew members in lifeboat starting procedures—the life you save could be your own.
• Consult the official IMO guidance on lifeboat appliances for technical and regulatory updates.

Real-Life Example: Learning from the Deck

In my time as an engine cadet, we once found our lifeboat engine wouldn’t start during a routine drill. After some troubleshooting, we realized air was trapped in the fuel line following a recent filter change. Bleeding the system solved the issue—reminding me how even small steps make a big difference.

Have you ever faced a similar situation? What was the culprit? Sharing experiences helps all of us learn and improve maritime safety.

Conclusion: Stay Prepared, Stay Safe

No seafarer wants to discover a lifeboat engine won’t start when lives are on the line. By following these systematic checks, documenting your work, and staying updated on international standards, you can be confident your lifeboat is always ready for an emergency. Simple routine care, a watchful eye, and readiness make all the difference out at sea.

Remember: A working lifeboat engine could be the difference between rescue and disaster. Make regular checks a habit—not just a checkbox on the list.
