Question 1 of 2066636ee728f7522a1c518b21

In storm conditions, with the wind and waves from the port bow of the DEEP DRILLER in 400 feet water depth, the tensions in mooring lines 1 and 2 are 400 kips. Completely slacking the mooring lines 5 and 6 reduces the tension in mooring lines 1 and 2 to about __________.

🔍 Key Concepts

• Mooring system load sharing between opposing lines in a spread moor • Effect of slacking opposite (leeward) lines on the tension of windward lines • How environmental forces (wind, wave, current) are balanced by the mooring pattern

💭 Think About

• Visualize the rig from above with lines numbered around the compass. If wind and waves are from the port bow, which lines are most directly taking that load? • If you completely slack the lines on the opposite side (5 and 6), what happens to the ability of the mooring system to share and balance the load? Does that generally make the heavily loaded lines carry more, less, or about the same tension? • Compare each answer choice to the original 400‑kip tension. Which values represent a significant relief in load, and which are closer to the original storm load?

✅ Before You Answer

• Identify which lines (1,2 vs. 5,6) are on the weather side vs. lee side relative to the port‑bow seas. • Check whether removing opposing restraint (by slacking 5 and 6) should cause a large reduction, a small reduction, or an increase in the load on 1 and 2. • Ensure your chosen value is physically consistent with how tension redistributes when some mooring lines no longer share the load.
