In deballasting to survival draft because of extreme wind and wave loads, thrusters or propulsion, if available, should be used to __________.

Correct Answer: Option C — reduce windward mooring line tensions

During adverse weather and deballasting operations, utilizing thrusters or propulsion counteracts environmental forces, specifically reducing windward mooring line tensions to prevent parting lines, structural overload, and potential snapping hazards under extreme hydrodynamic loads.
