70% to pass

While the DEEP DRILLER is loaded as shown in Sample Form #4 (Drilling), casing is accidentally dropped over the port side. Because the sounding level and port aft inclination are slowly increasing, you decide that tank 10P has minor damage. Among the possible corrective actions is _______________.

A dump the mud

B counterflood into 10P

C deballast from tank 9P

D counterflood into 2S

AI Explanation

The correct answer is C) deballast from tank 9P. When a casing is accidentally dropped over the port side, causing the sounding level and port aft inclination to slowly increase, it indicates that tank 10P has sustained minor damage. To correct this situation, the appropriate action is to deballast from tank 9P, which is located on the opposite side of the vessel (starboard side). This will help to counteract the listing and maintain the vessel's stability. Dumping the mud (option A) or counterfloooding into 10P (option B) or 2S (option D) would not be the correct corrective actions in this scenario.
