Mooring line parameters for OC3-Hywind OFWT

Dear Jason,

Our lab is planning to conduct a model test using the OC3-Hywind OFWT concept. I’ve noticed that for numerical calculation, FAST uses a simplified model adding a yaw stiffness instead of the original delta-line concept described in your report “Definition of the Floating System for Phase IV of OC3”.
So I would be very appreciated if you could help me find the original mooring system configurations and the original mooring line parameters.
Thank you very much.

Best regards.

Dear Yu Ma,

When the OC3-Hywind specification document was originally published, I was able to obtain information from Statoil regarding the specifications of the delta connection and multisegment lines; however, at the time, Statoil requested that I not redistribute those details to the entire OC3 group. I’ve recently heard from others that they were able to obtain information regarding the delta when they contacted Statoil. I suggest you contact Finn Gunnar Nielsen of Statoil from which I obtained the original data.

Best regards,
