AB Since wind turbine is located offshore, transportation and installation of an offshore wind turbine have high capital costs. The method of preassembly is used to optimize the use of the transportation vessel that is chartered to transport and install the wind turbine on an offshore remote location. Until this study is conducted, there is no offshore wind farm in Indonesia. This study uses the methodology of annual average wind velocity and bathymetry data to determine a possible location for an offshore wind farm on the Indonesian sea. The total duration of transportation and installation of wind turbines to construct a wind farm in Indonesia is calculated using scenarios of different preassembly methods and transportation vessels. By doing a comparison of different scenarios, the optimal combination of total duration and costs can be seen. The determined transportation vessel on this thesis is a jack up barge and Self-Propelled Installation Vessel (SPIV). The least time spent to construct a wind farm on the Indonesian sea of both transportation vessels is by using the preassembly of the “Bunny-Ear” method with the wind turbine tower in one piece and the remaining blade. It can be concluded that to optimize the transport cost of offshore wind farm installation on Indonesian sea is by using the combination of said preassembly method and by using jack up barge with the total duration of wind turbine transport and installation of 34 Days. 6 Days longer than the other scenarios of using SPIV with the same preassembly method.
