Damping ratios UMaine VoluturnUS-S FOWT

[andreowhite]

Hi everyone:
Does anyone know where I can find the damping ratios for UMaine VolturnUS-S FOWT?

Thank you.

Hi Andre, can you be more specific please?

Hi Matthew, I would like to find out what are the values of the damping ratios for the different degrees of freedom (surge, heave etc.) of the platform.

Hi @mattEhall just checking if I am now clear.
In the paper by Allen et al. (2020), which defined the UMaine VolturnUS-S platform, there is a graph of damping ratio vs initial cycle amplitude but I do not know if it possible to extract the damping ratio for each mode of vibration from that and I am not sure what initial cycle amplitude is. All I would like is to find out damping ratio for surge, heave and pitch DOFs.
Hope I am clear now.

Regards,
AOAW

@mattEhall @gbarter we never got back to @andreowhite unfortunately. is this issue still relevant, or shall we close it?
