The steel wall thickness of the buoyancy column is problematic as it is excessively thin.

Dear @Jason.Jonkman,

I hope you are doing well.

In the paper titled “Model Development and Loads Analysis of an Offshore Wind Turbine on a Tension Leg Platform, with a Comparison to Other Floating Turbine Concepts,” Table 4 mentions that in the MIT paper “Parametric Design of Floating Wind Turbines,” the diameter of the TLP buoyancy column ranges from 17 to 44 meters, with a steel wall thickness of 0.015 meters. The structural stiffness is notably low, and the MIT paper does not mention the steel wall thickness. The table is shown as follows. Could you provide some optimization recommendations?

Thank you in advance for your help.

Dear @JiaZhuang.Qin,

I agree that this thickness sounds low, but at the time this work was performed, I don’t recall that any structural analysis was performed. If I recall correctly, this thickness was only used to identify the contribution of steel versus ballast mass and the floater was treated as one lumped rigid body in the analysis anyway.

Best regards,
