An extensive code-to-code comparison of a modified version of IEA15MW-UMaine Floating Wind Turbine for H2020 HIPERWIND project

Abstract

International audienceAn extensive code-to-code comparison among DIEGO, DLW and HAWC2 has been performed on a floating wind turbine (modified version of UMaine floater with IEAWIND 15MW wind turbine). In total, 10 cases are compared, and a few key results of this comparison are reported in this paper. The load cases have been defined in the D1.2 and the results are presented in this document. From the comparisons, it is clearly seen that the results predicted by the three codes are in general good agreement despite some differences in specific degrees of freedom like sway and yaw for the extreme wind park case would require additional investigations
