Jan De Nul has completed an EPCI scope for foundations, power cables and scour protection on the Formosa 1 Phase 2 offshore wind farm, located in Miaoli County, Taiwan.
The wind farm is owned by a partnership of Ørsted (35%), JERA (32.5%), Macquarie Capital (25%) and Swancor Holding (7.5%).
Jan De Nul engineered, procured and installed twenty offshore wind turbine 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, seventeen inter array cables and three subsea export cables of 33kV 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 engaged and contracted various service and subcontract agreements with local companies in Taiwan. In addition to using the 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 many other minor services.
Peter De Pooter, manager Offshore Renewables at Jan De Nul, said: “Our local integration in Taiwan has been ongoing for the last 20 years thanks to our various maritime activities throughout the region. In the past year, we have signed different agreements with local suppliers for this project in Taiwan. Leveraging the local supply chain fits perfectly in our philosophy of involving local companies as much as possible in offshore wind construction.”
