From the Ground Up: GS Entec Delivers First All-Domestic Monopiles for Nakwol Offshore Wind Project

All Monopiles for Large-Scale Offshore Wind Farms Over 100MW Are Now Domestically Produced
3 Trillion KRW Facility Investment Targets the Global Market
Securing Follow-Up Projects Such as Hanbit Offshore Wind

GS Entec has demonstrated its domestic manufacturing capabilities by supplying a large number of domestically produced monopiles (monopile·foundation structures) to the Yeonggwang Nakwol offshore wind farm in Jeollanam-do. This marks the first case in which only domestically produced monopiles have been used in a large-scale offshore wind project, where European products were previously dominant. As a result, expectations are rising for the expansion of the export base of Korea's offshore wind industry.

GS Entec, a GS Group affiliate specializing in offshore wind foundation structures, announced on the 22nd that it has completed the delivery of 50 out of 64 monopiles supplied for the Yeonggwang Nakwol Offshore Wind Project. The Yeonggwang Nakwol project is a 365MW offshore wind farm being built in the waters off Nakwol-myeon, Yeonggwang-gun, Jeollanam-do, and will install 64 wind turbines each with a capacity of 5.7MW. Last year, GS Entec signed a contract worth approximately 200 billion KRW to supply all the monopiles for this project.

GS Entec plans to complete delivery of the remaining monopiles by October. A monopile is a key component that supports offshore wind turbines, made by welding large steel plates into a cylindrical shape and fixing it to the seabed. The company explained that the simple structure allows for a shorter production period and higher cost competitiveness, leading to rapidly increasing global demand.

With this project, GS Entec has set a precedent by supplying only domestically produced monopiles to a large-scale offshore wind farm with a capacity of over 100MW. The company has proven both the quality and mass production capability of domestic equipment, which is considered significant for future supply chain independence and export expansion across the domestic industry.

The company is also accelerating the expansion of its production capacity. GS Entec is investing a total of 300 billion KRW to introduce the latest automated facilities from Sif, the world's leading offshore wind foundation manufacturer based in the Netherlands. The facilities are scheduled to be completed in the first half of next year, at which point production capacity is expected to double compared to current levels.

The company is also targeting major projects such as the Hanbit Offshore Wind Project (344MW) on the west coast of Jeollanam-do, which is scheduled to begin construction in 2027. This project is expected to test the domestic procurement system for key equipment and contribute to establishing an export base through localization. GS Entec is also accelerating its overseas market strategy. The company aims to strengthen its position in the global supply chain by targeting the offshore wind markets in Asia, including Japan, Taiwan, and Vietnam.

A GS Entec official stated, "Through the Yeonggwang Nakwol project, our capabilities in monopile manufacturing and delivery have been thoroughly verified," adding, "We will establish ourselves as a key partner in the global offshore wind market by pursuing follow-up projects such as Hanbit Offshore Wind and expanding exports."

Founded in 1988, GS Entec started as a manufacturer of chemical equipment for oil refining and petrochemical plants. After being acquired by GS Global in 2010, the company has been transitioning to eco-friendly new businesses such as offshore wind power since the 2020s.
