For floating tidal turbine platforms, the turbine forces and resulting platform motions have a direct impact on the lifetime of its moorings and cables. Toward this end, the tidal sector has a requirement to predict accurate tidal turbine loading on floating platforms such that mooring life and cable longevity can be determined. This project will investigate the coupling of wind-turbine modelling software FAST with the cable dynamics software ProteusDS to more accurately predict the fatigue life and loading on cables. The expected outcome is the development of a feature in ProteusDS which enables more accurate turbine modelling. This FAST turbine modelling feature will enable tidal developers to more accurately predict mooring and power cable loading, which is critical for reducing their project operational risks.
