This work provides a benchmark study regarding the open-source panel method codes of two floating wind turbine platforms. HAMS, NEMOH, and WAMIT are compared in terms of their results, computational performance, user-friendliness, and, flexibility. WAMIT’s data is sourced from previous publications for the OC3 Hywind Spar and OC4 DeepCWind Semisubmersible. These reference values are compared to NEMOH and HAMS for wave excitation forces, added mass values, and potential damping. The study aims to help researchers to choose an open-source alternative to a validated commercial code.
