Deck General USCG Question #5236 (Set 163)

For a semisubmersible moored in heavy weather conditions, the weather lines should be adjusted so that several lines carry about the same tension, and the leeward lines are __________.

Official USCG Answer & Rule Citation

Correct Answer: Option B — paid out to reduce weather mooring line tensions

Heavy weather mooring management for semisubmersibles requires maintaining weather-side line tension while paying out leeward lines. This deliberate action prevents excessive line overloading, reduces peak dynamic tensions, and accommodates vessel offset without overstressing the mooring winch and windlass brake holding capacities.
