Question 4574 Deck General

The correct answer is C) adjust tow line length. When a MODU (Mobile Offshore Drilling Unit) under tow starts jumping on its tow line, the most appropriate action to alleviate the condition is to adjust the tow line length. Increasing the tow line length can help reduce the tension and movements caused by the jumping, stabilizing the MODU and preventing potential damage to the tow line or the vessels involved. The other options, such as slowing down (A), changing course (B), or heaving to (D), may not be as effective in addressing the specific issue of a jumping MODU under tow. Adjusting the tow line length is the most direct and appropriate action to take in this situation.
