Jan De Nul installs Formosa 2 export cables

Jan De Nul Group’s Cable Laying Vessel Willem de Vlamingh has installed the four export cables with a total length of 34 km on the 376 MW Formosa 2 offshore wind farm in Taiwan.

Willem de Vlamingh was able to position itself close to the beach thereby limiting the shore pull distance to around 1,250 metres. At the beach landing, the cables have been pulled through four HDD ducts into the transition joint bays.

Willem de Vlamingh also acted as a Trenching Support Vessel which, together with TSHD Niña and Starfish outfitted with an in-house designed jet-skid tool, in the meantime also completed the export cable burial works.

For the installation of the export cables, 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. This local network was set up with the support of Jan De Nul’s partner, Hung Hua Corporation.

For the Formosa 2 project, Jan De Nul Group is responsible for the foundation design, fabrication and installation, as well as for the design, supply and installation of the subsea cables.

Developed by JERA (49%), Macquarie’s Green Investment Group (26%) and Swancor Renewable Energy (25%), Formosa 2 will be one of Taiwan’s largest offshore wind projects. The project is located between four and ten nautical miles off Miaoli County and will consist of 47 turbines each with an 8 MW capacity. With an overall capacity of 376 MW, it is expected to produce enough power for up to 380,000 Taiwanese families with green energy.
