The emergency power system for the DEEP DRILLER should be placed in operation when the weather forecast predicts winds greater than 90 knots and when _______________.
AI Explanation
The correct answer is B) evacuating the unit.
The emergency power system for the DEEP DRILLER should be placed in operation when the weather forecast predicts winds greater than 90 knots and when evacuating the unit. This is because the emergency power system is critical to providing backup power during an emergency situation, such as when the crew needs to evacuate the offshore drilling unit.
The other options are incorrect because they do not directly relate to the conditions that would require the emergency power system to be activated. Unexpected list and trim (A), deballasting (C), and ballasting (D) are not directly linked to the need to evacuate the unit, which is the key factor that would necessitate the use of the emergency power system.
