Question 5108 Deck General

70% to pass

The COASTAL DRILLER, while operating with minimal wave clearance, is inclined 0.5 degrees bow down. Lowering the stern may place the hull in the wave action. The recommended course of action is to _______________.

A jack the hull down on the aft two legs
B jack the hull up on the bow leg
C transfer weight, such as drill water, toward the stern
D prepare to take action in case inclination increases
AI Explanation

The correct answer is B) jack the hull up on the bow leg. When a vessel is operating with minimal wave clearance and is inclined bow down, the recommended course of action is to jack up the hull on the bow leg. This helps to increase the stern draft and reduce the likelihood of the hull being submerged in the wave action, which could be dangerous. The other options are not recommended in this scenario. Jacking down the aft legs (A) would further decrease the stern draft, exacerbating the problem. Transferring weight to the stern (C) may not be sufficient to counteract the bow-down inclination. Merely preparing for increased inclination (D) does not directly address the current situation.
