Formosa 4 is developed by Synera Renewable Energy and is located around 20km off the coast of Miaoli County. 

Once operational, it will generate 495MW of renewable energy and is expected to play a significant role in Taiwan’s transition to green energy. 

The contract will see the deployment of several vessels from DEME’s fleet, including Green Jade, a floating offshore installation vessel, designed and built in Taiwan by CDWE.  

DEME has been active in Taiwan since 2019, co-founding CDWE, the country’s first offshore wind contractor, and contributing to projects such as Zhong Neng, Changfang Xidao, Hai Long, and the Greater Changhua offshore wind farm project.

DEME Asia-Pacific Offshore Energy general manager Frank Jonckheere said: “The Formosa 4 contract builds on DEME’s strong track record in Taiwan. We are proud to play a significant role in advancing Taiwan’s clean energy transition and supporting its long-term vision for renewables.  

“Through our joint venture CDWE, we provide integrated solutions that help our clients successfully develop their projects. In addition to bringing decades of knowledge and experience to Taiwan, we are nurturing local marine engineering talents and seafarers specialised in offshore wind who will help drive the industry forward for years to come.”  

The foundation installation works are expected to begin in the first half of 2027, subject to the final investment decision. 

DEME operates as a global contractor in offshore energy, environmental remediation, dredging, and marine infrastructure, and is active in concessions across offshore wind, green hydrogen, marine infrastructure, and deep-sea mineral harvesting. 

With a workforce of 5,800 professionals, DEME achieved a turnover of €4.1bn ($4.78bn) and an earnings before interest, taxes, depreciation, and amortisation of €764m in 2024. 

Last year, DEME secured a contract in the Netherlands for the OranjeWind offshore wind farm. This contract involved the transportation and installation of inter-array cables and secondary steel.
