What is the mandated interval for emptying the fuel tanks and changing fuel in lifeboats on offshore drilling units?

• A. Every 12 months
• B. Every 18 months
• C. Every 24 months
• D. Every 36 months

Answer: (C)

Regular maintenance of lifeboat fuel systems is essential to ensure the engine will start and run reliably in an emergency. Fuel in lifeboat tanks can degrade over time, absorb moisture, and collect contaminants. If stale fuel, water, or sediment are present, the engine may fail to start or run poorly when it’s most needed. Emptying the fuel tanks and replacing the fuel at a set interval removes these risks by ensuring the fuel is fresh and the tank is clean for the next deployment.

The mandated interval of every two years aligns with standard safety equipment service cycles and keeps the lifeboat fuel system in good condition without imposing excessive downtime. Shorter intervals would add unnecessary maintenance and downtime, while longer intervals increase the risk of fuel quality issues and engine problems when the lifeboat is finally used. Always follow the manufacturer's maintenance manual and the vessel’s safety management system for specifics.
