Question 13General Subjects - QMED

The correct answer is D) manually operated with one pump located in the engine room and the other in the shaft alley of the watertight door. This is correct because the illustration GS-0103 represents the typical arrangement of manually operated hydraulic pumps for watertight doors on vessels. Per Coast Guard regulations, these pumps must be located on both sides of a watertight door to allow for manual operation in the event of a power failure, with one pump in the engine room and the other in the shaft alley. The other options are incorrect because they do not accurately reflect the required location and operation of the hydraulic pumps as specified in the Coast Guard regulations for watertight door systems.
