Jan De Nul has completed the installation of all export cables for the 376 MW Formosa 2 offshore wind farm in Taiwan.
The company installed four export cables with a total length of 34 kilometres using its cable laying vessel (CLV) Willem de Vlamingh, which was able to position itself close to the beach and limit the shore pull distance to around 1,250 metres, according to Jan De Nul.
At the beach landing, the cables were pulled through four HDD ducts into the transition joint bays.
CLV Willem de Vlamingh also acted as trenching support vessel which, together with the trailing suction hopper dredger (TSHD) Niña and a Starfish vessel (outfitted with an in-house designed jet-skid tool), also completed the export cable burial works.
For the beach pull assistance works, dive support, the installation of the HDD ducts, as well as the supply and operation of support vessels, Jan De Nul relied on the local supply chain set up with the support of Hung Hua Corporation, Jan De Nul said.
Jan De Nul was selected as the EPCI contractor for the wind farm’s foundations and subsea cables in October 2019. The company started construction in June last year, when the onshore and nearshore works for the landfall site commenced.
Formosa 2, located off the coast of Miaoli County in northwestern Taiwan, is scheduled to be built and put into operation this year.
The 376 MW wind farm, developed by a partnership between JERA, Macquarie’s Green Investment Group, and Swancor Renewable Energy, will comprise 47 Siemens Gamesa 8 MW turbines installed in water depths of up to 55 metres.
