Q

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 __________.

🔍 Key Concepts

• Leeward vs. windward mooring lines and how wind and seas load each side of the mooring system • Behavior of a moored drilling unit after disconnecting the marine riser in heavy weather • Risks of having mooring lines too tight or too slack in storm conditions

💭 Think About

• Think about which side (windward or leeward) is carrying most of the environmental load in a storm and what that means for safe line tension on the opposite side. • If the rig is being pushed strongly in one direction, what could happen to the leeward lines if they are kept very tight? What if they are completely slack? • How would you adjust the leeward lines to reduce shock loading and prevent line failure while still maintaining control of the rig’s position?

✅ Before You Answer

• Confirm what leeward means in relation to the direction of the prevailing wind and seas. • Consider the consequence of over‑tensioning leeward lines when the rig is already being pulled hard toward the windward side. • Consider the danger of zero control on the leeward side if lines are allowed to become completely slack in storm conditions.
