Abstract
The rapid development of offshore floating wind farms poses ever strong demands for technical innovation within wind turbine installation operation. A low-height lifting system was, correspondingly, conceptualized to improve the installation efficiency for a pre-assembled offshore wind turbine onto a SPAR buoy. However, before putting into practice, the performance of such complex system on the operation should be further verified and optimized by the integration of sub-systems, such as mechanical, hydraulic, and control sub-systems, in a simulation workbench. Benefited from the development of coupled simulation, the technical difficulties in the monolithic simulation for such a multi-domain system can be alleviated by a co-simulation approach based on functional mock-up interfaces (FMI) standard which allows modularized subsystems to be modeled independently in a high-fidelity level but simulated together. Therefore, here we develop a preliminary modularization solution based on FMI-based co-simulation for the simulation workbench of offshore floating wind turbine installation operation by low-height lifting system. The commercial simulation tool specialized for marine operation is adopted as subsystem simulator. Each simulator is packaged as a functional mock-up unit (FMU), and then parameterized and connected with each other based on system structure and parameterization (SSP) standard. Finally, the co-simulation performance is tested in Vico platform. The modularization solution is discussed for the basis of future investigations.
