Semco Maritime and its consortium partner PTSC M&C have completed the load-out and sail-away of the second and last offshore substation for the Hai Long offshore wind project in Taiwan.

“With the successful 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 Hai Long Offshore Wind Project is progressing well to meet the goal of contributing to the realization of the Taiwanese government’s energy transition ambitions,” said the consortium partners.

The companies have 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. Semco Maritime and PTSC M&C were awarded the EPC contract for Hai Long 2 and the 504 MW Hai Long 3 in August 2022.

The Hai Long 3 offshore substation is expected to be installed and prepared for offshore commissioning by the second quarter of 2025.

The first offshore substation topside, measuring 52 metres in length, 38 metres in width, and 32 metres in height, was installed at the site by CSBC-DEME Wind Engineering’s (CDWE) Green Jade vessel in May 2024.

The company is responsible for the transportation and installation of the foundations, turbines, and offshore substations for the two offshore wind farms making up the project.
