■ Loading capacity nearly doubled, improving cable laying efficiency  
■ Execution capabilities for large-scale projects strengthened, creating foundation for greater revenue growth  
■ Greater competitiveness for national projects such as West Coast HVDC Energy Highway 


LS Marine Solution (CEO Kim Byeong-ok) has completed performance upgrades to its GL2030 submarine cable laying vessel, strengthening its competitiveness in the domestic and international large-scale offshore wind power and extra-high-voltage direct-current (HVDC) markets.

The company announced on the 22nd that it has expanded the loading capacity of the GL2030 from 4,000 tons to 7,000 tons, nearly doubling the number of cables it can carry.  

The vessel can now construct long-distance sections of over 100 km continuously, minimizing the number of departures and reducing construction time and costs. This will significantly boost construction efficiency for large-scale offshore wind power and HVDC projects.

This upgrade comes in response to the surging demand for submarine power infrastructure. The government recently announced a bidding plan for a total of 55 GW of offshore wind power by 2035 and is actively promoting the West Coast HVDC Energy Highway project.

In addition, the number of submarine power and communication cable projects is rapidly increasing, fueled by the proliferation of AI data centers and the resulting construction of cross-border submarine communication networks.

LS Marine Solution is strengthening its vessel competitiveness for different marine environments and project scales. While the GL2030 is optimized for shallow coastal waters, the company is also building a 13,000-ton-class next-generation laying vessel. Once it is completed, the company will have a two-track construction system capable of handling long-distance, large-capacity projects.

LS Marine Solution has already proven its competitiveness by securing contracts for the Jeju Submarine No. 2 and No. 3 Interconnection projects, as well as the Japan-Korea Submarine Communication Network (JAKO) project promoted by Microsoft and Amazon.

"We plan to participate in more core national power grid projects such as the West Coast HVDC Energy Highway," said a company spokesperson. "Drawing on LS GreenLink, LS Cable & System's US submarine cable production base, we will also fast-track our expansion into global markets, including the US and Europe."
