Since a clevis-type joint has a assembly tolerance between bracket and sleeve, bolt size and fastening specification should be designed with consideration of a clamping load loss. Torque only tightening method shows a big variation of pretension load. Otherwise, torque and angle over the yield tightening method shows a reduced variation and increased minimum pretension load. This paper presents an effect of assembly tolerance on a clamping load loss and evaluates a variation of pretension load according to two different tightening methods. The theoretical modeling method to calculate a snug torque and angle for torque and angle controlled tightening is also introduced.

The 3MW OWEC demonstrator project in Korea will be the first offshore wind project with Korean turbine, Doosan WinDS3000, and constructed on the north-eastern sea of Jeju Island as the water depth of 15m. Integrated loadings of wind and wave are investigated to describe a design loads for both extreme and fatigue conditions using GH-Bladed. A dynamic behaviour of substructure strongly affects a substructure loadings. The jacket structure is designed in accordance with DNV guidelines. The results of this paper show overall design process of offshore substructure as a complex jacket concept and this design process can be implemented on a design of monopile and tripod structures.
