A validated numerical model is a powerful tool that enables the simulation of a
plethora of LCs, where the behaviour of the offshore wind turbine can be studied in order
to optimise the design of the WT, the support structure (fixed or floating) and
auxiliary equipment.

TECNALIA works in all the main aspects related to floating offshore wind, from site conditions analysis to new generation Wind Turbine, supporting structure, mooring
systems, and underwater electrical equipment design, and it is particularly involved in coupled numerical simulation tools for calculating dynamics of offshore wind turbines
(OWT). In order to calculate motions and loads through multiphysics analysis, an OWT modeling has to consider support structure hydrodynamics, tower mechanics, station
keeping system, rotor-nacelle assembly and control system behaviour. TECNALIA is working in different floating offshore wind projects using and testing aerodynamic and
hydrodynamic coupled tools performing time domain simulations, which are also validated with experimental testing.
