LS Marine Solution to Build Asia's Largest HVDC Cable Laying Vessel

Investment of 345.8 Billion KRW
Operations to Begin in the First Half of 2028

LS Marine Solution will construct a new submarine cable laying vessel of the world's largest class. This move aims to strengthen the company's equipment competitiveness in order to expand orders for large-scale high-voltage direct current (HVDC) and offshore wind power projects.


On May 27, LS Marine Solution announced its plan to build a large laying vessel with a cable loading capacity of 13,000 tons. The large laying vessel is a key piece of equipment essential for establishing long-distance independent power transmission networks, and the company is investing a total of 345.8 billion KRW in the project.

The new vessel is considered state-of-the-art equipment capable of laying HVDC submarine cables and optical cables simultaneously. It is a high-specification vessel, with only three such ships currently in operation worldwide, and it enables stable construction even in long-distance, high-voltage, and deep-sea environments. The company describes it as a technology optimized for building HVDC power grids.


In terms of cable loading capacity, the vessel will rank among the world's top five and will be the largest in Asia. Most of the approximately 20 laying vessels worldwide are concentrated in Europe, so it is significant that Korea is securing equipment competitiveness. The vessel is expected to be completed after about two years of construction and will begin operation in the first half of 2028. LS Marine Solution plans to fully implement a global turnkey (integrated order) system that covers design, production, and construction, in connection with the U.S. LS Greenlink submarine cable facility, which will enter mass production at the same time.


LS Marine Solution is strengthening its technological capabilities in response to the 'West Coast Submarine Power Highway' project. In submarine sections where watertightness is critical, it is necessary to minimize cable joints. LS Marine Solution believes that, in Korea, the new laying vessel will be the only ship capable of such long-distance continuous laying.


Kim Byungok, CEO of LS Marine Solution, stated, "The new laying vessel will be a turning point that goes beyond simply expanding our equipment, enhancing the nation's power grid independence and strategic response capabilities," adding, "Together with LS Cable & System, we will actively enter not only large-scale offshore wind power projects at home and abroad, but also ultra-long-distance submarine network construction projects."
