This paper presents results of numerical computations for \ud floating off-shore wind\ud turbines using, as an example, a machine of 10-MW rated power. The hydrodynamic\ud loads on the support platform are computed using the Smoothed Particle Hydrodynamics method, which is mesh-free and represents the water and \ud floating structures as a set\ud of particles. The aerodynamic loads on the rotor are computed using the Helicopter\ud Multi-Block \ud ow solver. The method solves the Navier-Stokes equations in integral\ud form using the arbitrary Lagrangian-Eulerian formulation for time-dependent domains\ud with moving boundaries. The motion of the \ud floating off-shore wind turbine is computed\ud using a Multi-Body Dynamic Model of rigid bodies and frictionless joints. Mooring\ud cables are modelled as a set of springs and dampers. The loosely coupled algorithm\ud used in this work is described in detail and the obtained results are presented.
