The installation was carried by the vessels Seaway Yudin and Siem Barracuda.

The first batch of pin piles was manufactured and offloaded at the Port of Taichung in July 2020.

Each of the pin piles – produced by EEW Korea, EEW KHPC and EEW Malaysia – is up to 78.9 metres long, has an outside diameter of 2.4 metres, and weighs up to 280 tonnes.

In October 2019, Jan De Nul was selected as the EPCI contractor for the project’s foundations and subsea cables.

The company later subcontracted EEW to produce the pin piles, Saipem and Sembcorp to deliver the jacket foundations, and Seaway 7 to install both at the Formosa 2 project site, located off the coast of Miaoli County in northwestern Taiwan.

That same month, Saipem completed the fabrication of 32 wind turbine jacket foundations for Jan de Nul.

The 376 MW offshore wind project will comprise 47 Siemens 8 MW turbines installed in water depths of up to 55 metres.

Formosa 2 is being developed by JERA, Macquarie’s Green Investment Group (GIG), and Swancor Renewable Energy. Once fully commissioned, the wind farm is expected to provide enough renewable electricity to supply power to approximately 380,000 households.
