VERIFICATION OF LOAD CALCULATION BASED ON SITE MEASUREMENTS OF A 7MW OFFSHORE WIND TURBINE ON V-SHAPED SEMI-SUBMERSIBLE FLOATING STRUCTURE

抄録

In this paper, the measured and calculated load of 7MW offshore wind turbine on V-shaped semi-submersible floating structure installed off the coast of Fukushima prefecture is presented. Simulation model is established taking account of literatures, in-house CFD and water tank test results. Numerical simulations have been carried out for both fatigue and extreme load and compared with the measurement results which have been obtained throughout the measurement campaign. From the comparisons, it is concluded that the analytical model and methodologies used for the evaluation are appropriate and suitable for the floating offshore wind turbine on V-shaped semi-submersible floating structure.
