Question 3363 Deck General

The correct answer is B) 3 months. According to the regulations set by the US Coast Guard, the lifeboats on offshore drilling units must be lowered to the water and maneuvered at least once every 3 months. This is to ensure the proper functioning and readiness of the lifeboats in case of an emergency. Lowering and maneuvering the lifeboats on a regular basis helps to verify that the equipment is in good working condition and that the crew is trained and prepared to launch the lifeboats effectively. The other options are incorrect because they do not align with the Coast Guard's regulatory requirement. Lowering the lifeboats every 2 months, 6 months, or 12 months would not meet the necessary standard for ensuring the safety and preparedness of the offshore drilling unit.
