On August 28, HD Hyundai Heavy Industries announced that it has obtained an international design verification letter from DNV for its self-developed 500MW-class offshore substation (OSS). The international design verification letter is a document that certifies whether the design and technical documents meet international regulations and standards. With this certification, HD Hyundai Heavy Industries has secured the stability and technical feasibility of its design.

In particular, the newly developed 500MW-class offshore substation model by HD Hyundai Heavy Industries has localized key equipment, established a stable supply chain, and maximized synergy with domestic equipment suppliers.

An offshore substation is a core facility required to transmit electricity generated from offshore wind farms to land. It collects electricity produced by wind turbines installed at sea and transmits it to shore while minimizing power loss.

This 500MW-class model is a standard design that can be applied to large-scale offshore wind power projects and is capable of transmitting the electricity generated by a total of 35 wind turbines, each with a capacity of 14MW.

HD Hyundai Heavy Industries expects to make a significant contribution to revitalizing the domestic offshore wind power industry ecosystem by aligning with the government’s “Renewable Energy 3020” implementation plan and large-scale offshore wind farm development policies. Won Kwangsik, Head of Marine Energy Business Division at HD Hyundai Heavy Industries, stated, “With the acquisition of this verification letter, we plan to actively pursue orders in the offshore wind power market. We will continue to develop offshore substation models with various capacities and configurations, expand our product portfolio, and strengthen our competitiveness in securing orders.”
