O&M of Crew Transfer Vessels Against Floating Wind Turbines – Modelling the Water Run-up Effect During Personnel Transfer in Waves with Short Periods.

EasyChair Preprint 10759

Abstract

For floating wind farms in areas like in Mediterranean Sea where waves with short periods occur, it is important to make sure that the Crew Transfer Vessel main deck does not get flooded. Method description Water elevation at boarding point: • Calculate the water elevation downstream of the floating wind turbine boarding point, which is by accounting for the wave masking by its floater. Vessel heave at boarding point: • Calculate the Crew Transfer Vessel heave at the floating wind turbine boarding point. Relative range between ship heave and wave elevation at berthing point: • Calculate the wave height and periods where that relative range gets lower than zero, which is when the vessel deck becomes flooded by the waves. Main results and findings The benchmark is another reference which calculated the flooding risk while berthing the vessel against a fixed wind turbine monopile: it compares satisfacto-rily with the present calculation.
