Jan De Nul Group cable laying vessel Willem de Vlamingh has completed installation of the four export cables at the 376MW Formosa 2 offshore wind farm in Taiwan.
The vessel was able to position itself close to the beach thanks to its shallow draft design thereby limiting the shore pull distance to around 1250 metres, the company said.
Cables totalling 34km have been installed at the wind farm.
At the beach landing, the cables have been pulled through four HDD ducts into the transition joint bays, Jan De Nul said.
Willem de Vlamingh also acted as the trenching support vessel which, together with TSHD Nina and a Starfish outfitted with an in-house designed jet-skid tool, completed the export cable burial works.
Jan De Nul Group relied on its local supply chain network for the performance of the beach pull assistance works, dive support, the installation of the HDD ducts, as well as the supply and operation of support vessels.
The local network was set up with the support of Jan De Nul’s long-standing partner Hung Hua Corporation.
Jan De Nul Group is also responsible for the foundation design, fabrication and installation, as well as for the design, supply and installation of the subsea cables.
Formosa 2 is a joint venture project by JERA, Macquarie’s Green Investment Group and Swancor Renewable Energy.
The project is located between four and 10 nautical miles off Miaoli County.
