Description

In recent years, single-point mooring (SPM) concept is widely employed in several branches in the naval architecture and marine engineering field, such as FPSOs, offshore oil rigs, etc. In the present work, we perform some numerical studies on the DeepCwind semisubmersible wind turbine, using the state-of-the-art open-source tool Fatigue, Aerodynamics, Structures and Turbulence (FAST). Results show that the SPM layout affects the natural periods of the wind turbine in rotational modes, as well as the mooring stiffness in the diagonal rotational and crossing rotational-translational terms, especially with relation to the yaw mode. Comparisons of the Response Amplitude Operators (RAOs) elucidate that the presence of wind affects significantly the sway, roll and yaw motions of the SPM layout. Finally, the weathervane test shows that an asymmetry exists in the free-yaw motion response when the semisubmersible wind turbine is moored by an SPM system.
