Abstract
Floating offshore wind turbines (FOWTs) may offer a solution to exploit
resources at deep-water sites, but there are still many design challenges
to overcome. Numerical modelling enables developers to explore these
challenges with reduced risk. However, available tools typically simplify
critical hydrodynamic interactions and so, here, a model, including highfidelity hydrodynamic simulation, is presented and compared against
existing solutions to two IEA OC4 load cases, which use lower-fidelity
approaches. Two mooring models are investigated: a quasi-static
approach that predicts a near-sinusoidal response in phase with the surge
motion; and a dynamic approach which predicts considerable
nonlinearity and a phase shift.
