The total length is 34 km (21 mi).
Thanks to her shallow draft design, the Willem de Vlamingh was able to position itself close to the beach thereby limiting the shore pull distance to around 1,250 m (4,101 ft). At the beach landing, the cables have been pulled through four HDD ducts into the transition joint bays.
The Willem de Vlamingh also acted as a trenching support vessel. The trialing suction hopper dredger Niña and a Starfish outfitted with an in-house designed jet-skid tool completed the export cable burial works.
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 Macquarie’s Green Investment Group, JERA, and Swancor Renewable Energy, Formosa 2 will have 47 Siemens 8-MW turbines on jacket foundations in up to 55 m (180 ft) water depth. The project is between 4 and 10 nautical miles off Miaoli County.
