The Formosa 4 offshore wind farm, developed by Synera Renewable Energy (SRE), is a 495 MW project located off the coast of Taiwan and represents SRE’s third offshore wind development in the country. The project plays an important role in supporting Taiwan’s renewable energy targets and localization policy.
The First-Cut Ceremony signifies the transition of the Formosa 4 OSS project from engineering and procurement into full-scale construction. Under the EPC contract awarded in late August 2025, the Semco Maritime – PTSC M&C consortium is responsible for the design, procurement, construction, and commissioning of the offshore substation’s jacket and topside, with scheduled delivery by the end of 2027.
Semco Maritime is leading the engineering, procurement, and commissioning of the main MV/HV electrical systems and auxiliary platform systems, supported by its long-term partner ISC Consulting Engineers. PTSC M&C is responsible for the jacket EPC scope, procurement of remaining topside equipment and materials, as well as fabrication of the topside at its Ho Chi Minh yard.
The ceremony was attended by representatives from Synera Renewable Energy, senior management of Semco Maritime and PTSC M&C, along with project teams and key stakeholders, reflecting the strong collaboration and shared commitment to project excellence.
“Having progressed through more than a year of engineering and preparation, today’s first steel cutting marks the formal transition of the Formosa 4 project into the construction phase. From this point forward, our consortium is fully focused on delivering the project in line with the key milestones ahead,” said Mr. Frank Holm, Senior Vice President, COO Renewables, Semco Maritime.
“Commencing fabrication for the Formosa 4 Offshore Substation is a significant milestone for PTSC M&C. This project builds upon our established track record in Taiwan and our close cooperation with Semco Maritime. With the experience gained from previous offshore substation projects, our teams are fully prepared to execute this scope efficiently and responsibly, contributing to the long-term development of offshore wind in the region,” said Mr. To Ngoc Tu, Managing Director of PTSC M&C.
Following the successful delivery of the Hai Long Offshore Substation and the ongoing Feng Miao Offshore Substation project, Formosa 4 becomes the consortium’s third offshore substation project in Taiwan. This milestone further strengthens the position of the Semco Maritime – PTSC M&C consortium as a trusted EPC contractor in the offshore wind supply chain across the region.
About PTSC M&C, a subsidiary of PTSC Corporation which is in turn a member of Vietnam Oil & Gas Group (PetroVietnam), is the leading EPCIC contractor in Vietnam in the offshore Oil & Gas and Renewables Energy sectors. To date, PTSC M&C has successfully delivered more than 80 projects in and outside Vietnam.
