Uzunoglu, E., Liu, Y. and Guedes Soares, C. (2023), Performance of the open-source potential flow solver HAMS in estimating the hydrodynamic properties of a floating wind turbine, Trends in Renewable Energies Offshore, Guedes Soares, C. (Ed.), Taylor and Francis Group, London, UK, pp. 619-630
This work evaluates the use of an open-source potential flow solver in the hydrodynamic analysis of floating wind turbine dynamics. The platform in question is a free-float capable TLP design. It performs as barge in the towing condition, and it is a TLP when installed. In the barge mode, it has moon-pool type openings that improve towing dynamics, leading to a complex geometry. The hydrodynamic properties are evaluated in both conditions (i.e., installed and transport) using WAMIT and HAMS. Added mass, potential damping, and wave exciting forces are compared in the frequency domain. Then, the dynamics of the platform in the installed condition is evaluated in time domain, using FAST. The time domain evaluation clarifies whether the differences between solvers affect the estimation of coupled motions resulting from the hydrodynamic and aerodynamic loads.
