Question 5107Deck General70% to pass
The COASTAL DRILLER is operating with a wave clearance of about 20 feet. The out-of-level alarm sounds and the unit is found to be inclined 0.5 degree bow down. The recommended course of action is to _______________.
AI Explanation
The correct answer is A) jack the hull down on the aft two legs.
The reasoning is that with a wave clearance of 20 feet and the unit inclined 0.5 degrees bow down, the recommended course of action is to jack the hull down on the aft two legs. This will help to level the unit and restore the proper wave clearance, reducing the risk of the unit becoming further inclined or unstable.
The other options are incorrect because: B) transferring weight toward the stern would not address the root cause of the inclination; C) preparing for increased inclination does not actively correct the problem; and D) jacking up the bow leg would further increase the bow-down inclination, which is the opposite of what is needed.
