For traditional o -shore structures, there is an almost direct correlation between the environmental loads and the derived structural loads. For a wind turbine foundation, on the other hand, loads are driven not only by the severity of the environment but by how the turbine is being operated. It has been possible to validate the accuracy of the analysis programs for floating offshore structures as well as for bottom-fixed offshore turbines. Unfortunately, this same luxury has not yet been extended to FOWTs. First of all, there are only two commercial scaled floating offshore wind turbines in the world, and it is di cult to perform a model test that accurately reflects the floating body response and the turbine induced response at the same time. Highly spe- cialized software has been developed to capture these e ects. The American Bureau of Shipping (ABS) worked with Texas A&M University to develop software that combines the well-known FAST program developed by the United States National Renewable Energy Laboratory (NREL) with CHARM3D, a time domain global perfor- mance analysis program for integrated oating hull-mooring/cable systems that was developed for global performance and For consistency, the assumption was made that the NREL 5 MW baseline o shore wind turbine would be installed on each conceptual design studied.
