The Formosa 4 offshore wind farm, developed by SRE, is a 495 MW project and represents SRE’s third offshore wind initiative in Taiwan. It aligns with Taiwan’s localization policy, advancing the nation’s renewable energy ambitions.
Following extensive negotiation rounds, the Semco Maritime and PTSC M&C consortium was awarded the EPC contract in late August 2025 with scheduled delivery end of 2027. The consortium’s scope includes design, procurement, construction, and commissioning of the offshore substation’s jacket and topside. Semco Maritime will lead 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 will oversee the jacket EPC scope; procurement of remaining topside equipment and materials, and fabrication of the topside, all at its yard in Vung Tau, Vietnam.
“Semco Maritime and PTSC M&C are excited to be awarded the Formosa 4 substation. We are proud that SRE has entrusted our consortium with this project, and we will draw on our joint experience in Taiwan to deliver a stellar result and contribute to the continued development of the Taiwanese offshore wind industry”, says Mr. Thomas Thomsen - Senior Vice President Renewables of Semco Maritime.
“This project marks another successful milestone for PTSC M&C and Semco Maritime. It is our honour to be trusted by SRE to contribute to such an important project in Taiwanese offshore wind industry. Our strong partnership and collaborative spirit will remain as the key to ensuring the project’s success”, says Mr. To Ngoc Tu, PTSC M&C’s Managing Director.
Alongside the previously won projects, Formosa 4 marks the consortium’s third OSS project contracted in Taiwan following the successful delivery of Hai Long OSS project and the ongoing Feng Miao OSS project. With all projects on track, the Formosa 4 contract solidifies the consortium as a trusted contractor in the offshore wind supply chain and sustainability in the region.
