Consortium partners Semco Maritime and PTSC M&C have completed the successful load-out and sail-away of the second and last offshore substation for the 1GW Hai Long offshore wind project in Taiwan.
Consisting of Hai Long 2 and Hai Long 3, the offshore wind project is being jointly developed by Mitsui & Co Ltd, Northland Power Inc and Gentari.
Semco Maritime and PTSC M&C were awarded the EPC contract for Hai Long 2 and Hai Long 3 in 2022.
With the load-out and sail-away of offshore substation topsides for Hai Long 2 in April 2024 and Hai Long 3 on 8 March 2025, the project is progressing well to meet the goal of contributing to the realisation of the Taiwanese government’s energy transition ambitions, the partners said.
The wind farm is in the Taiwan Strait 45-70km off the Changhua coast with a water depth of 35-55 metres.
The consortium has delivered detailed design and procurement as well as the construction of the two offshore substations at PTSC M&C’s yard in Vung Tau City, Southern Vietnam.
The Hai Long 3 offshore substation is expected to be installed and prepared for offshore commissioning by the second quarter of 2025.
Semco Maritime’s senior vice-president for renewables Frank Holm said: “It has been a pleasure to cooperate closely with the parties involved in the Hai Long offshore wind project in recent years, and the strong team performance with our consortium partner and sub-contractors on this exciting project holds great promises for the future.”
PTSC M&C managing director To Ngoc Tu said: “This significant milestone in the Hai Long projects exemplifies the unwavering commitment and expertise of our esteemed consortium with Semco Maritime in delivering premier renewable energy services.
“We remain resolute in our dedication to fulfilling our commitments to our valued clients and advancing the offshore wind energy sector.”
Hai Long project director Tim Kittelhake said: “The overall construction of the Hai Long project continues to progress steadily. We are very pleased to have reached this critical milestone of our Hai Long project through close cooperation with our partners at Semco Maritime and PTSC M&C.
“We now look forward to completing the next phase of the projects, enabling us to bring clean energy to more than a million households in Taiwan.”
