Regular maintenance of lifeboat fuel systems is essential to ensure the lifeboat can be relied on in an emergency. Fuel left in lifeboat tanks can deteriorate, develop water or sediment, or become contaminated over time. Changing the fuel on a set cycle helps keep the fuel clean and the engine and related components in good working order when needed.

On offshore drilling units, the standard interval for emptying the lifeboat fuel tanks and refreshing the fuel is every two years. This two-year cycle provides a practical balance: it minimizes the risk of degraded fuel while avoiding unnecessary frequent handling and waste. If there were signs of contamination or fuel quality problems, maintenance would be done sooner, but the default requirement is a biennial refresh.

So the appropriate interval is at least once every 24 months.
