Taiwanese offshore vessel operator Dong Fang Offshore (DFO) has won a landmark 15-year contract with Synera Renewable Energy (SRE) to provide a service operations vessel (SOV) for the Formosa 4 offshore wind project.

The deal is described as the longest SOV fixture seen to date in Taiwan’s offshore wind sector. The Taiwan-flagged vessel will be custom-built to support both the construction and long-term operations and maintenance of Formosa 4 and SRE’s broader asset base.

Formosa 4 is located off the coast of Miaoli County and represents SRE’s third offshore wind project in Taiwan. The wind farm secured 495 MW of capacity in Taiwan’s Phase 3 Zonal Development auction in late 2022 and received its establishment permit in 2024.

DFO, a subsidiary of Hung Hua Construction, was established in 2019 as the Asia-Pacific region’s first dedicated offshore wind vessel operator. The company has a fleet of 18 vessels, including several under construction. It has three SOVs currently being built at Vard in Norway — all earmarked for work in Taiwan’s offshore wind market.
