Jan De Nul has completed an extensive project for the foundations, power cables and scour protection on the Formosa 1 (Phase 2) offshore windfarm
Jan De Nul Group engineered, procured and installed 20 foundations consisting of a monopile and transition piece with a grouted connection. Around the monopile foundations 56,000 tonnes of scour protection have been installed.
In addition, 17 inter array cables and three 33-kV export cables were designed, procured, installed, buried, terminated and tested. On land, the connection with the substation was made through 12 km of land power cables.
In addition to some international service and product providers, Jan De Nul Group engaged and contracted various service and subcontract agreements with local companies in Taiwan.
Using Port of Taichung as a marshalling harbour, Jan De Nul Group utilised the local supply chain for quarried rock production, rock load-out operations, storage and transport of the foundation structures, beach pull assistance works, dive support supply, various support vessels, installation of transition joint bays, HDD ducts, land cables installation, and other minor services.
The windfarm is owned by Formosa 1 Wind Power Co, a partnership of Ørsted (35%), JERA (32.5%), Macquarie Capital (25%) and Swancor Holding (7.5%), located in Miaoli County, Taiwan.
