Question 3716 Deck General

The correct answer is A) landing area and sources of vapor ignition. This is because the regulations for offshore drilling units require that any helicopter fuel storage tanks must be installed as far as practicable from the landing area and potential sources of vapor ignition, such as the engine room or the drill floor. This is to minimize the risk of fire or explosion in the event of a fuel leak or spill near the helicopter landing zone or other ignition sources. The other options are incorrect because the engine room, main deck, and drill floor are not the primary considerations for the placement of the fuel storage tanks. The primary concern is to isolate the tanks from the landing area and ignition sources.
