A consortium led by Semco Maritime and PTSC M&C has won a contract to supply two offshore substations for the 1044MW Hai Long offshore wind project off Taiwan.
The engineering, procurement and construction (EPC) contract follows on from the consortium’s selection as a “preferred supplier” in October 2021.
Hai Long is being jointly developed by Northland Power, Yushan Energy and Mitsui & Co and consists of the Hai Long 2 and Hai Long 3 offshore wind farms in the Taiwan Strait around 50 km from shore.
After being awarded the preferred supplier agreement in late 2021, the consortium led by Semco Maritime with PTSC M&C, supported by primary sub-contractor ISC Consulting Engineers, has initiated the execution of the project by entering the EPC contract with Hai Long Offshore Wind Project.
“Our initial cooperation with the parties involved in the Hai Long Offshore Wind Project has been a true pleasure, and we are thrilled that the contract has been signed enabling us to take the next steps on this journey with our consortium partner PTSC M&C and sub-contractors,” said Vice President Renewables, Semco Maritime, Frank Holm.
Following the EPC contract signing, the consortium will proceed with the detailed design, procurement, construction and commissioning of the two offshore substations including jackets.
These will be fabricated at PTSC M&C’s yard in Vungtau City, in southern Vietnam.
The project is planned for offshore installation in 2024 and completion of commissioning in 2026.
Felipe Montero, Project Director of Hai Long, said “As preferred suppliers for our offshore substations Semco Maritime and PTSC M&C have proven that they are the best possible partners for delivering a hugely important part of our Hai Long projects, and we are pleased to have signed the EPC contract with them, which will allow us to continue to making progress and reaching new milestones.”
Hai Long will contribute to the realisation of the Taiwanese government’s ambition of reaching 5.5GW of installed offshore wind capacity and securing a “leading position” for Taiwan in offshore wind in east Asia.
