In recent major developments, LS Marine Solution changed its name from KT Submarine Co., Ltd. to LS Marine Solution Co., Ltd. in August 2023. The company has embarked on significant strategic expansion by investing approximately KRW 345.8 billion (EUR 221 million) to acquire a new high-spec cable laying vessel designed for high-voltage direct current (HVDC) cable installation, with operations scheduled to commence in 2028. This new vessel, constructed by Tersan Shipyard in Turkey, will be Asia's largest vessel of its type with a cable loading capacity of 13,000 tonnes and is equipped with advanced sustainability and energy efficiency technologies. Furthermore, LS Marine Solution has secured a substantial order backlog amounting to approximately KRW 700 billion, representing five times its previous year’s revenue, underscoring its growth and strong market position. The company continues to enhance its technological leadership and service capacity to cater to expanding offshore wind power markets and other global submarine cable projects, reinforcing its status as a total marine solutions provider in both domestic and international markets.
