Question 1 of 27070

Given the same water depth and line tension, the catenary length of a 90 pound/foot mooring chain in comparison to the catenary length of a 19 pound/foot wire rope mooring line will be __________.

🔍 Key Concepts

• Catenary curve behavior and how weight per foot of a line affects its sag for the same horizontal tension • Relationship between unit weight of the mooring line and how much of it must be paid out to reach a given water depth • Difference in behavior between a heavier chain and a lighter wire rope when suspended under the same conditions

💭 Think About

• For two lines under the same horizontal tension and spanning the same depth, what happens to the shape of the curve if one line is much heavier per foot? • If you increase the weight per foot of the mooring line, do you need more length, less length, or the same length to reach from the bow down to the seabed? • Visualize both lines from the vessel to the anchor: which one will hang with more sag, and how does that sag change the total length needed?

✅ Before You Answer

• Think about how increased weight per foot affects the amount of sag for a given tension and span • Make sure you distinguish between scope (length paid out) and vertical depth (which is held constant here) • Confirm whether a heavier line needs more or less horizontal reach to connect the same two vertical points at the same tension
