Abstract
To estimate the characteristics of the substructure of jacket type offshore wind turbine, this research was studied on European offshore wind turbine models and its related systems. In the study, the substructure types of offshore wind turbine in the coastal region can be divided into two ones such as a monopile or gravity and a jacket or tripod, which are strongly related with the water depth. The gravity or monopile type is constructed in the area of shallow water depth less than 20m, however the jacket type is in relatively deep water depth as the 30~40m. Two types also were considered to a structure stability and economical feasibility since the construction budget and structure safety for the construction of offshore wind turbine were important things. In the study, the jacket type was analyzed to apply it to 35m and 45m water depth of Jeju island coastal area based on the theoretical and technical approaches of the substructure because the island coastal region has deep water depth. In the analysis procedures, this study also considered the ocean environmental conditions such as wind waves, tide and wind forces effecting to the jacket. To estimate the jacket structure safety, the jacket structure stress and displacement and other deformation items were calculated. From the calculation of the jacket structure, this research found that the selected parameters of the ocean environment conditions and wind force were reasonable, and the jacket structure analysis results by numerical model were very useful for constructing offshore wind turbine in 35m and 45m depths of Jeju coastal area. Therefore, this research found that the offshore jacket structures proposed by the paper can be applied to the real coastal environmental conditions in Jeju ocean.
