Question 4363 Deck General

The correct answer is D) both port-side ballast pumps. In the event of major damage to column C1P while the DEEP DRILLER is on location, the recommended procedure is to use both port-side ballast pumps to pump from the port-forward lower-hull tanks. This is because the port-side ballast pumps are specifically designed and positioned to handle the ballast system on that side of the vessel, making them the most effective and appropriate choice for this type of emergency situation. The other options are not correct because: A) the drill water pump is not intended for ballast system operations, B) the saltwater service pump may not have the capacity or positioning to effectively manage the ballast system, and C) using all four ballast pumps would be unnecessary and potentially overkill for the specific issue at hand.
