Question 25

The Correct Answer is D **Explanation for Option D (100%):** Option D (100%) is correct because regulatory bodies, such as the United States Coast Guard (USCG) and international maritime organizations (IMO), mandate that all vessels and offshore drilling units must carry lifesaving equipment (including inflatable liferafts and lifeboats) sufficient to accommodate **100% of the total number of persons allowed aboard** (crew and rig personnel). This requirement ensures that in the event of an emergency requiring abandonment of the unit, there is capacity for everyone to safely evacuate, adhering to the fundamental safety principle of "a place for every person." **Explanation for Incorrect Options:** * **A) 20%:** This percentage is far too low and would be grossly non-compliant with safety regulations, leaving 80% of personnel without a survival craft upon abandonment. * **B) 30%:** Similar to A, this percentage is inadequate and violates the fundamental regulatory requirement for 100% accommodation in survival craft. * **C) 50%:** While 50% provides capacity for half of the personnel, it is still insufficient. Survival craft regulations demand capacity for all persons on board, not just half.
