Generate new mode shapes for the 5MW ITIBarge4 wind turbine

[Xin.Tong]

@Jason.Jonkman

Dear Xin,

I have not calculated this myself, but you could calculate it by hand by combining the mass and center of mass of the rotor/nacelle assembly of the NREL 5-MW turbine (from here: Using Aggregate Mass in ADAMS to Check NREL CS_Monopile.bmi - #2 by Jason.Jonkman), the tower, and the ITI Energy barge.

Best regards,

Dear Jason,

Thank you for your reply. I finally got the augmented (4,4) and (5,5) elements of the “mooring_K” matrix, which is -2.9153e+08 because for the ITIBarge4 turbine z is positive. Is such a large negative value reasonable? Thank you for your feedback.

Yours,
Xin
