A consortium comprising Denmark-based Semco Maritime and Vietnam’s PetroVietnam Technical Services Corporation (PTSC) has been selected to supply two offshore substations for the Hai Long 2 and Hai Long 3 offshore wind projects in Taiwan.

Semco described this deal as the largest offshore substations contract awarded in Taiwan to date, adding that it is also the consortium’s first contract.

The consortium — along with ISC Consulting Engineers — will execute the project, starting in the fourth quarter of 2021, with offshore installation planned in 2024 and completion of commissioning activities in 2026.

The contract includes the design, engineering, procurement, construction and commissioning of the two offshore substations including jackets, which will be manufactured at PTSC M&C’s yard in Vung Tau in southern Vietnam.

The Hai Long 2 and Hai Long 3 projects will be established off the Taiwanese coast and deliver more than 1 gigawatts of green wind energy when the projects are commissioned in 2025 or 2026, said Semco.

Felipe Montero, project director of Hai Long Offshore Wind Project, said: “With Semco Maritime and PTSC M&C as preferred suppliers for our offshore substations, we’re certain we’ve found the best possible partners for delivering a hugely important part of our Hai Long projects.
"The signature of this Preferred Supplier Agreement is another key milestone for Hai Long on the way to financial close and into construction.”

Hai Long Offshore Wind Project consists of Canada-based company Northland Power, Yushan Energy and Mitsui & Co.
