OC6 semisubmersible response to waves in offset positions caused by constant thrust loads

Abstract

In 2019, a semisubmersible floating wind foundation was tested in the Concept Basin of MARIN in waves and under several levels of constant thrust. This paper compares the motion of the floater and the tensions in its mooring lines in waves under different levels of thrust. The end goal of this work is to present experimental results of the response of a floating wind turbine semisubmersible under the combined effects of waves and constant thrust. As these new experiments were focused on the hydrodynamic response of the floater in its offset position, their results represent reference data for the validation of numerical tools that account for this offset in the calculation of the hydrodynamic loading and response.
