Question 5076 Deck General

The correct answer is D) ballast down. When a semisubmersible rig under tow experiences pounding on the forward transverse brace, the surest way to alleviate the condition is to ballast down the rig. Ballasting down the rig will increase its draft and submerge the forward transverse brace, reducing the pounding motion. This is the most effective solution, as it directly addresses the root cause of the issue. The other options are not as effective. Slowing down the tug (A) or changing course (B) may provide some relief, but do not directly address the pounding on the brace. Adjusting the length of the tow line (C) may help, but ballasting down is a more reliable solution.
