The provider of specialized services for the offshore trade, Jan De Nul Group said that its cable-laying vessel Willem de Vlamingh has completed set up of the three export cables on the 120MW Formosa 1 phase two offshore wind farm in Taiwan.
The maritime infrastructure main focus is dredging has an engineering procurement construction and installation (EPCI) contract for the overall balance of plant at the project.
These three export cables have been successfully put in within one week. Due to its shallow draft design, the Willem de Vlamingh was able to place in water depths of not more than 7 meters, thus limiting the shore pull distance to around 1,750 meters.
On the beach landing, the cables have been pulled through three HDD ducts into the joint transition bays. The Willem de Vlamingh can be acting as Trenching Support Vessel for the jet-trenching of each the export as well as the inter-array cables.
For the setup of the export cables, Jan De Nul Group relied on its native provide chain network for the efficiency of the beach pull help works including setting up of the HDD ducts, dive support and supply and operation of the help vessels.
Formosa owns the wind farm I Wind Energy Co. Ltd., a partnership of Orsted – 35%, JERA – 32.5%, Macquarie Capital – 25% and Swancor Holding – 7.5%.
The offshore wind farm is positioned around six kilometers off the west coast of the Miaoli district in the Taiwan Strait, with water depths ranging between 15 and 30 meters. The first demonstrator venture, comprising two wind generators with a total capacity of 8MW, is at the moment being extended. This second phase will add 20 offshore wind generators with a total capacity of 120MW to Formosa 1’s present 8MW capacity.
