Performance of barge-type floaters for floating wind turbine

Abstract

The hydrodynamic performance of barge-type floaters for floating wind turbine is analysed with and without moonpool. In the case of barge-type floaters with moonpool, the effect of moonpool sizes and its effects on the coupled dynamics of floater motions with waves and winds are studied and presented. The moonpool can be used as floating oscillating water column. The piston mode and sloshing mode are studied for the floaters with moonpool. The analysis is carried out for the floater’s motion responses in both regular and irregular waves. The wind turbine is positioned at the centre of the floater in all of the case studies. The numerical study on the coupled dynamic response of the barge-type floaters with the wind turbine support structure is conducted using aero-servo-hydroelastic simulation. The platform motion responses along with the power spectral density of the motion characteristics are analysed. © 2016 Taylor & Francis Group, London.
