This study is implemented the impact analysis of leveling system used to maintain the level of jacket structure in construction of jacket structure for wind turbine which widely used in offshore wind power. The major problem during the construction of offshore wind power is that a tower or bottom structure which are supporting structures of the generator are passing above the jacket, and it is necessary to maintain its leveling by accurately measuring the level of the jacket while constructing. Due to its purpose, the level of jacket is adjusted with the leveling system which operates hydraulically, but the leveling system inevitably exposed to the impact load during the pile drive. This study interpreted the influences of impact during the design or construction of the leveling system by considering the interaction between the ground and the jacket structures.
