360. 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 __________.

To address major damage to column C1P, use both port-side ballast pumps to dewater port-forward lower-hull tanks, as these pumps are specifically connected and approved for emergency dewatering and provide maximum controlled response on the damaged side. The ballast system is designated for ballast tank management, and the port-side pumps directly serve the relevant tanks. Using other pumps or all ballast pumps is inconsistent with procedures and could compromise stability.
