The consortium between Denmark-based Semco Maritime and Vietnamese PTSC Mechanical & Construction has secured an EPC contract for the offshore substation of the Formosa 4 offshore wind farm in Taiwan.

The offshore wind farm, developed by Taiwan-based Synera Renewable Energy, is a 495MW project and represents the company’s third offshore wind initiative in Taiwan.

The consortium’s scope includes design, procurement, construction, and commissioning of the offshore substation’s jacket and topside. The work under the EPC contract is scheduled to be completed by the end of 2027.

Semco Maritime will lead the engineering, procurement, and commissioning of the main MV/HV electrical systems and auxiliary platform systems, supported by 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 the work will be done at its yard in Vung Tau.

Alongside the previously won projects, Formosa 4 marks the consortium’s third OSS project contracted in Taiwan, following the successful delivery of the Hai Long OSS project and the ongoing Feng Miao OSS project.
