Boskalis to deploy 4 heavy transport vessels for Greater Changhua OSS and foundations transport

Boskalis will transport 66 suction bucket jacket foundations and one offshore substation (OSS) for Ørsted’s Greater Changhua 2b and 4 offshore wind farm in Taiwan. The activities are to start at the end of this year.

Boskalis will deploy four of their semi-submersible heavy transport vessels – Black Marlin, Blue Marlin, Mighty Servant 3 and Transshelf – to transport the foundations and the OSS (supplied by Engineering company Seatrium) from Singapore/Batam and the port of Taichung to the offshore wind farm in the Taiwan Strait.

Boskalis: “For many years, our vessels have sailed around the world with impressive cargoes ranging from huge offshore structures and drydocks to fish farms and even cruise ships. In recent years, cargoes have increasingly been destined for the realization of offshore wind farms, such as monopiles, jacket foundations as well as kilometers of power cable that transport the generated power at sea to the mainland. For the latter, we equipped the Transshelf with three modular cable carousels.

Prior to the Greater Changhua 2b and 4 project, these will be removed to create space for the transport of the OSS topside. Another example of our versatile fleet demonstrating that we are able to transport a wide variety of cargo, thereby contributing to the energy transition in multiple ways.”

Ørsted took the final investment decision for the 920 MW Greater Changhua 2b and 4 offshore wind farms, located some 35-60 kilometers off the Changhua coast in Taiwan, in March 2023 after having won the developments rights in 2018. Construction started in Q3 2023 and is set to be completed by the end of 2025. Another Dutch company involved in the project is Van Oord. The marine contractor will be responsible for the transport and installation of three export cables, with a total length of approximately 175 kilometres.
