초록

The offshore wind jacket substructures at the Tam-la and Southwest Project were built in Korea according to two-body separated construction. The installation of jacket substructures according to two-body separated construction is not economical due to an increased marine construction period. In this study, integrated construction is developed to install offshore wind jacket substructures quickly in order to reduce marine construction costs. In addition, the basic design of a jacket substructure with 5.0 MW turbine is made considering all environmental loads in the southwest sea off Korea such as wind, waves, current, etc. Finally, marine construction costs according to integrated construction are compared with two-body jacket separated construction. As a result, if jacket substructures are built using integrated construction, marine construction costs could be reduced by approximately 20 %.
