As the installation water depth of offshore wind turbines increases and their capacity is enlarged, the construction cases of XL monopiles has been growing in Europe. In addition, the development of installation systems has also increased to ensure the safety and workability of XL monopile installation. In this study, an upending system for XL monopiles was developed to secure the construction safety and workability of XL monopiles. The upending system is a temporary structure that can improve workability and prevent buckling and deformation of XL monopiles when a crane upends a XL monopile. The upending system is designed for the diameter, length and weight of XL monopiles, and in this study, it was designed to take into account D= 7 m, t= 100 mm, L= 41.6 m, and total weight of 1,000 tons. Rigid dynamics analysis was carried out to check the upending operation, and the interference of members was confirmed. In addition, the structural performance was examined with static and dynamic structural analyses of the upending system. Based on this study, it is expected that safe and economical installation will be achieved by applying the XL monopile upending system.

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 %.
