Question 5069 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. This allows the MODU to better respond to the motion of the towing vessel, reducing the stress on the tow line and preventing further issues. Slowing down (A) or changing course (B) may not be as effective in stabilizing the tow, while heaving to (D) is not the most appropriate action for this situation. Adjusting the tow line length is the recommended response to address a MODU that is jumping on its tow line, as it helps to better match the motion of the towed vessel with the towing vessel, alleviating the stress on the tow line.
