Multidisciplinary design analysis and optimization of floating offshore wind turbine substructures: A review

The development of novel energy technologies to meet net zero carbon emission is essential in the provision solutions realize an increasing worldwide demand for renewable energy. Floating Offshore Wind Turbine (FOWT) one emerging exploit vast wind resources available deep waters within offshore sector. However, as a result complexity FOWT system, bringing technology up speed requires detailed understanding different disciplines system and relationship between dynamics marine environment; hence, need Multidisciplinary Design Analysis Optimization (MDAO) system. This paper reviews MDAO substructures/platforms proposed literature. review covers overview floating turbine substructures’ concepts, design using geometric shape parameterization techniques analysis approaches (time frequency domain) response assessment It also provides comprehensive frameworks substructures. Regarding optimization aspect, some algorithms used substructure provided, i.e., from global search heuristic meta-heuristics local gradient-based algorithms. work further identifies research gaps main future areas address these are: space richness by adopting more advanced parametrization represent platform geometry (and other characteristics), utilize surrogate/meta models replace most computationally expensive high-fidelity needed quick sensitivity studies before analyses on selected are conducted, exploring upscaling parameters optimal parameterized platforms derived existing designs which can be coupled with new generation highly rated heavier turbines.
