On an offshore drilling unit, inflatable liferafts must accommodate what percentage of persons?

• A. 100%
• B. 80%
• C. 60%
• D. 40%

Answer: (A)

The key point is that life-saving equipment on offshore drilling units is sized to protect every person on board. Inflatable liferafts must collectively have the capacity to accommodate all personnel on the unit, so in an abandonment scenario no one is left without a raft. That means the total liferaft capacity equals 100% of the people on board, ensuring universal evacuation capability. If the capacity were only 80%, 60%, or 40%, some individuals would not have a liferaft to board, which would violate safety requirements and the unit’s muster plan. In practice, the on-board liferafts are arranged so their combined capacity matches the full complement of crew, contractors, and visitors.
