Yaw rotating platform

Dear @Pere.Palacin,

Yes, at this time, the platform-yaw motions are limited to about 15 degrees. We have an upcoming project starting soon that will upgrade ElastoDyn (as well as associated changes in SubDyn, HydroDyn, and the mooring modules) that will enable large floater yaw motion, but at this time, platform-yaw motions must be limited.

Best regards,

Dear @Jason.Jonkman ,

Iā€™m sorry to bring back this topic, but I wanted to ask you the right way to introduce the Yaw rotation of the platform. Should it be due to the torsion of the mooring system or there is a proper way of creating a pin joint between the semisub and the mooring system?

Thanks!

Dear @Pere.Palacin,

See my post dated Dec 6, 2016 in the following forum topic for information about how to model a mooring system with a turret in OpenFAST: Modelling of a two-bladed FWT with leaning tower and guy-wire.

Best regards,
