Measurement point used in NREL model test results

Dear Dr. Jason.

I am comparing the simulation result to model test results in nrel.gov/docs/fy13osti/57697.pdf.
Could you let me know the exact measurement point used in the model test results.
If the measurement point is different from our reference point, our results has to be transferred to the measurement point.
It can be either the free surface point or center of mass.

Thank you for your help.

Sincerely,
Daniel Kim

Dear Daniel,

I’m assuming you are referring to the platform motions. Regardless of where the platform motions where actually measured from, the comparison of motions (between measurement data and FAST simulations) in that OMAE paper was made at a reference point corresponding to the intersection of the tower centerline and still water level for the undisplaced system.

Best regards,
