In storm conditions, when the environmental conditions are such that the DEEP DRILLER has disconnected the marine riser, the two leeward mooring lines should be __________.

Correct Answer: Option B — completely slacked

Upon disconnecting the marine riser, station-keeping requirements change. Completely slacking leeward mooring lines prevents excessive structural counter-bending moments and fatigue when the vessel moves off-center, allowing the windward lines to absorb environmental forces safely without over-tensioning the system.
