As part of the national off-shore wind power development project by the government of Korea, the very first off-shore wind turbine utilizing tri-pod suction buckets for its sub-surface foundation has been successfully completed. This off-shore wind turbine with a capacity of 3MW has been designed, constructed, and installed in late 2016. It is located approximately 200 meters offshore with a water depth of approximately 10 meters. Sub-surface soil consists of interbedded clay and sand layers. Details of the design, construction, and installation of this wind turbine with tripod suction bucket foundation system are described and discussed.
