PO076: A Study for the effect on a dynamic power cable influenced by the motion of a floating offshore wind turbine

Abstract
Floating offshore wind turbines(FOWTs) can be broadly divided into four main parts: superstructure, substructure, mooring line, and power cable. The mooring line is an essential device for stationkeeping of FOWT and experiences significant tension due to environmental conditions and the motion of the substructure. Electricity generated by the wind turbine is transmitted to the mainland through power cables, which are closely related to the mooring lines influenced by environmental conditions and the motion of a FOWT. Although these power cable is designed in a lazy wave shape to be relatively free from tension loads, fatal tensions and bends can occur due to the effects of strong currents, wind, and waves. Currents have a direct impact on the configuration of the power cable, while wind and waves induce motion in a floating offshore wind turbine, affecting the power cable. A fully coupled dynamic analysis of the mooring-power cable was performed in this study, considering their interrelation. Additionally, this research organized environmental data from the southwest sea of South Korea to design the mooring tension of FOWT to meet the standards in both Serviceability Limit State (SLS) and Ultimate Limit State (ULS) conditions. During this calculation process, the effects of shape, tension, and curvature on safety were analyzed to ensure the safety of the power cable. This research concludes that understanding the behavior of the mooring-power cable is crucial for reliable operation of FOWT, particularly considering the variability of environmental conditions in the southwestern sea of South Korea.
