Aobserving the operation of the over speed trip
Bchecking the manual trip device for proper operation
Cassuring that the turbine casing drains are wired closed
Dopening all governor oil relay drains
AI Explanation
The correct answer is B) checking the manual trip device for proper operation. This is the correct answer because checking the manual trip device for proper operation is a critical precaution to observe prior to starting a turbine-driven cargo pump. The manual trip device is an important safety mechanism that can quickly shut down the turbine in the event of an emergency, and it is essential to ensure that it is functioning correctly before starting the pump. The other answer choices, while potentially relevant in other situations, are not the primary precautions that should be taken for a turbine-driven cargo pump. Options A, C, and D are not the most important steps to take before starting the pump.
