🔍 Key Concepts

• Effect of wind and sea from the port quarter on a floating drilling unit’s heading and heel • How mooring line locations (numbered 1–8) relate to the direction of environmental forces • Difference between a local tank problem (single ballast tank leak) and a global stability/position problem (mooring load changes, unexpected equalizing)

💭 Think About

• First picture the rig from above and mark where the port quarter is. Which numbered mooring lines would be taking the greatest load with strong wind and seas from that direction? • Ask yourself: would a single ballast tank leak or equalizing typically create both a starboard and forward inclination that matches the direction of the environmental forces? • Consider whether failure of lines on the upwind side or downwind side is more likely to allow the rig to move and heel in the direction described.

✅ Before You Answer

• Verify which side is port vs starboard and which way forward is on the mooring plan associated with Sample Load Form #4. • Check the numbering pattern of the mooring lines (1–8) to see which lines are roughly forward/aft, port/starboard, or on the quarters. • Confirm whether the described inclination direction (starboard and forward) is with or against the direction you’d expect if tanks on the starboard side were flooding or equalizing.
