Energy is a basic need that cannot be separated from human’s life. Almost all sectors in life require energy to meet human needs. One of the renewable energy sources is wind energy. Offshore wind turbine is a renewable energy source that recently has developed rapidly. Wind turbines built offshore have several advantages over onshore. To support the offshore wind turbine, there are several structural options that can be used. The jacket structure can be used for medium to deep seas. The jacket structure that supports the offshore wind turbine is composed of steel tubular members that are joined together by welding will then receive various loads acting on the jacket structure that finally will dictate the integrity of the structure. The purpose of this study is to investigate local stress distribution of critical tubular joint of an offshore wind turbine jacket by using finite element model. Normally, there are two conditions of operation on wind turbine, which are operating when the environmental conditions are normal, and parked when the environmental conditions are extreme. The result showed interesting local stress distribution due to all three types of loading which are axial, in-plane bending moment (IPB), and out-of-plane bending moment (OPB) loading conditions.
