Outline of Final Research Achievements

Researches have been carried out on development of the CFD method for predicting maximum wave loads and maximum wind loads on floating offshore wind turbine systems. The CIP based Cartesian grid method has been improved and a wind turbine model and a mooring line model have been implemented. Model experiments on the floating wind turbine platform under strong wind and large wave conditions have also been carried out for validation of the CFD code.
