Hello everyone,
I am currently researching the buoy with mooring lines. The configuration of the setup is below. The buoy is connected with a sonar sensor and mooring lines.
The mooring line includes 4 components. The 2nd component of the mooring line consists of a buoy. How can I define the mooring lines with 4 sections and a buoy?
I hope to receive your advice.
Thank you so much.

Hello,Â
The nonlinear caternary allows you to do this; you can create for the same cable definition different sections with the same (or different) section types, length and specify whether this particular part of the cable is expected to touch down on the seabed.
I hope this helps.

Dear Ingrid M,
Thank you so much for your response. I defined it following the AQWA manual. However, it has a problem with the weight/Unit length input. One of the mooring line sections has a lightweight cable with a Mass/Unit Length of 0.478 kg/m in section 2. And I can define this section's properties. Is there any way to create a lightweight cable?

Hi,
for catenaries, the weight should be at least 1.025 kg/m2 (your density devided by 1000). You can also increase the equivalent cross-sectional area so that the overall buoyancy is correct.
I hope this helps.
