INNOSEA (part of OWC) was instructed by EDF EN to perform wind turbine generator (WTG) integrated loads assessment work for the Provence Grand Large floating offshore wind project. The scope included setting up a numerical framework aligned with OrcaFlex requirements, developing and validating a DLL, and creating a pre-processing tool to automate OrcaFlex input creation for the integrated load assessment loop, supporting the coupled turbine–foundation engineering for the floating units.
