Question 4476 Deck General

The correct answer is B) 20 feet. Before deballasting to survival draft in preparation for heavy weather, the DEEP DRILLER Operations Manual recommends that the mooring lines be slacked 20 feet. This allows the vessel to ride higher in the water and be more responsive to wave action, reducing the risk of damage to the mooring system or the vessel itself during the heavy weather event. The other options, such as 10 feet (A), 30 feet (C), or 40 feet (D), would either not provide enough slack (10 feet) or potentially create too much slack, which could lead to the mooring lines becoming tangled or the vessel drifting excessively (30 or 40 feet).
