LS Marine Solutions plans to build the world's largest submarine cable laying vessel to participate in more large-scale HVDC and offshore wind power projects.

LS Marine Solutions announced on the 27th that it has decided to invest a total of KRW 345.8 billion in building a large-scale cable laying vessel with a cable loading capacity of 13,000 tons. This cable laying ship is the key piece of equipment for building long-distance, self-supporting power grids.

The new vessel is a state-of-the-art, high-spec vessel capable of simultaneously laying HVDC submarine cables and optical cables, and there are currently only three vessels of its type operating worldwide. It is capable of stable cable laying work even in long-distance, high-voltage, and deep-water environments, and is technologically optimized for building HVDC power grids.

LS Marine Solutions is strengthening its technological capabilities in response to the West Coast HVDC Energy Expressway project. The new cable laying vessel of LS Marine Solutions will be the only vessel capable of long-distance continuous cable laying work, especially in submarine sections where watertightness is critical and cable connections must be minimized.

The vessel is designed to be the largest in Asia and one of the top five in the world in terms of cable loading capacity, and will be highly competitive, as there are only about 20 cable laying vessels in the world. With most of these laying vessels owned by European countries, Korea is emerging as a key hub in the reorganization of the global supply chain.

The vessel is expected to begin operation in the first half of 2028 following a construction period of approximately two years. LS Marine Solutions plans to operate a global turnkey project system encompassing design, production, and construction in conjunction with the LS GreenLink submarine cable plant in the U.S., which is scheduled to begin mass production at the same time. 

“Building this new vessel is not only intended to expand equipment capacity, but will also be a turning point for enhancing national power grid independence and strategic response capabilities,” said Kim Byung-ok, CEO of LS Marine Solutions. “In cooperation with LS Cable & System, we plan to advance into large-scale offshore wind power projects at home and abroad, as well as ultra-long-distance submarine network construction projects.”
