Question 3440 Deck General

70% to pass

For a semisubmersible moored in heavy weather conditions, the leeward lines should be paid out, and the windward lines adjusted so that _______________.

A at least 1,000 feet of chain lie along the bottom

B several weather lines carry about the same tension

C the unit remains as close to the hole as possible

D the vertical component of chain tension at the lower fairlead is not excessive

AI Explanation

The correct answer is B) several weather lines carry about the same tension. In heavy weather conditions, it is important to adjust the lines on a semisubmersible to balance the tension across the windward lines. This helps maintain the stability and position of the unit. Paying out the leeward lines allows the semisubmersible to weather the storm, while adjusting the windward lines to have similar tension ensures the forces are distributed evenly. The other options, such as having 1,000 feet of chain on the bottom or keeping the unit close to the hole, do not directly address the need to balance the line tensions in heavy weather.
