HD Hyundai Heavy Pursues Offshore Substation Project

HD Hyundai Heavy Industries has secured a significant contract to build an offshore substation in Taean, South Korea. The project, which involves engineering, procurement, fabrication, installation, and commissioning, is being carried out by Taean Wind Power Co., Ltd. This joint venture is comprised of Singapore-based Vena Energy, Danish firm Copenhagen Infrastructure Partners, and Korea Western Power.

The two entities confirmed the contract after a preliminary design agreement in March and a preferred supply contract in July. Offshore substations are crucial components that elevate voltage to transmit electricity from offshore wind turbines to land. The substation in question will be erected at a wind farm near Gaeuido-ri in Taean County, playing a pivotal role in power transmission.

HD Hyundai Heavy Industries has leveraged its expertise in offshore plant sector to pursue this renewable energy infrastructure project. To ensure its stability, the company has undergone a rigorous international design verification process, obtaining basic design verification from Norway's DNV in 2025 and detailed design verification in August.

This makes HD Hyundai Heavy Industries the first domestic offshore substation project to meet international regulations and standards. The company is confident in its ability to execute the project stably, using its existing offshore plant capabilities and expecting to secure more business opportunities in the renewable energy sector.
