Question 5102Deck General70% to pass
While drilling loaded as shown in Sample Load Form #4 (Drilling), the DEEP DRILLER suffers a sudden unexpected inclination to port and aft. Strong winds and high waves are from the starboard bow. Among the possible causes, you should consider _______________.
AI Explanation
The correct answer is B) failure of mooring lines 3 or 4.
The sudden unexpected inclination to port and aft, combined with strong winds and high waves from the starboard bow, suggests a failure of the mooring lines on the starboard side (lines 3 or 4). This would cause the vessel to shift in that direction, leading to the observed list.
The other options are incorrect because: A) Equalizing ballast tanks would not cause a sudden inclination, C) a leak in a single ballast tank would not lead to this degree of instability, and D) failure of mooring lines 1 or 2 on the port side would not result in a list to port and aft.
