Jan De Nul has finished installing foundations, power cables and scour protection on the 120MW second phase of the Formosa 1 offshore wind farm off the coast of Taiwan.
The contractor took four months to complete the engineering, procurement, construction and installation contract, which included installing the project’s 20 turbine foundations.
The foundations comprise monopiles and transition pieces with a grouted connection.
Around the monopiles 56,000 tonnes of scour protection have been installed.
Seventeen array cables and three subsea export cables of 33kV were also designed, procured, installed, buried, terminated and tested as part of the EPCI contract.
Jan De Nul offshore renewables manager Peter De Pooter 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.”
In addition to using the Port of Taichung as a marshalling harbour, Jan De Nul Group used 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, ducts, land cables installation, and other minor services.
The wind farm is owned by a partnership between Orsted (35%), JERA (32.5%), Macquarie Capital (25%) and Swancor Holding (7.5%).
The second phase of Formosa 1 is located around 6 km off the west coast of the Miaoli district in the Taiwan Strait, with water depths ranging between 15 and 30 metres.
The first, operational, phase consists of two 4MW wind turbines with a total capacity of 8MW. The second phase is due online in 2020.
