In case of major damage to column C1P while the DEEP DRILLER is on location, you should pump from port-forward lower-hull tanks using __________.

Correct Answer: Option D — both port-side ballast pumps

Major structural damage to column C1P impairs primary ballast capabilities, necessitating maximum redundancy. Operating both port-side ballast pumps concurrently ensures adequate suction head and discharge volume from the port-forward lower-hull tanks to maintain necessary stability and list control.
