The two companies plan to jointly develop high-performance ROV trenchers, related operating technologies, and installation solutions, with the aim of building domestic alternatives in areas that currently depend heavily on overseas equipment and expertise. Through these efforts, they aim to strengthen the self-reliance of Korea’s submarine cable industry while improving project execution reliability and installation efficiency. At present, most burial equipment deployed in large-scale, technically challenging submarine cable projects, including HVDC projects, is foreign-made, and its operation often requires specialized personnel from overseas. In particular, waters off Korea’s southwest coast are characterized by strong tidal currents, high turbidity, and shallow depths. These conditions have long underscored the need for high-performance ROV trenchers optimized for Korea’s marine environment. Under the agreement, the two companies will jointly develop high-performance ROV trenchers and operating systems for use in offshore wind inter-array and export cable systems, as well as long-distance grid interconnection and HVDC submarine cable projects. They also plan to conduct demonstration testing of submarine cable burial and protection technologies and pursue commercialization. Going forward, the companies plan to deploy the developed equipment and technologies in actual submarine cable installation projects. They will also participate in national R&D programs to further advance the technologies and jointly explore opportunities in overseas markets. Through this joint development initiative, Taihan aims to build in-house capabilities in core submarine cable installation technologies and strengthen its ability to execute large-scale HVDC projects, including the West Coast Energy Highway. Building on this, the company plans to further enhance its turnkey execution capabilities across the entire submarine cable value chain, from design and manufacturing through transportation, laying, and burial. Panstar Robotics is a specialized marine robotics company established by the Korea Institute of Robotics & Technology Convergence (KIRO). Based on AI robotics technologies, the company provides a range of marine robotics services. It possesses core technologies related to ROVs for submarine cable burial and has built technological expertise and field execution capabilities by deploying its proprietary robots in submarine cable projects in Korea and overseas. The signing ceremony was held at Taihan Cable & Solution’s headquarters in Hoban Park II, Seocho-gu, Seoul. Key attendees included Chun-won Lee, Executive Vice President and Head of the Submarine Business Division; Hyun-joo Kim, Executive Vice President and Head of the Production and Technology Division; Dong-seok Hong, Managing Director and Head of the R&D Center; and Min Jeong-tak, CEO of Panstar Robotics. “Developing high-performance ROVs domestically for submarine cable installation goes beyond simply developing equipment; it is an important initiative to strengthen the competitiveness of Korea’s submarine cable supply chain,” said Chun-won Lee, Executive Vice President of Taihan Cable & Solution. “We will continue to strengthen competitiveness across the entire submarine cable value chain, contribute to national energy security, and play a key role in the global market as a total solutions provider for submarine cables.” Meanwhile, Taihan continues to expand investments to stabilize Korea’s submarine cable supply chain. Following the completion of Submarine Cable Plant 1, the company is currently constructing Submarine Cable Plant 2, which will be capable of producing 640kV HVDC submarine cables, further expanding its domestic production base. In addition, following the introduction of PALOS, Korea’s first cable-laying vessel (CLV) dedicated to offshore wind projects, Taihan added the Skandi Connector to its fleet, strengthening its project execution capabilities across submarine cable transportation, laying, and burial. In recognition of these continued efforts to expand its production and installation infrastructure, Taihan was selected in December 2025 as a Leading Company for Supply Chain Stabilization in the submarine cable sector.

Following PALOS, the only offshore wind CLV currently owned domestically, this marks the second offshore wind-dedicated CLV introduced in Korea. The vessel is capable of loading up to 7,000 tons of submarine cable in a single operation. With this acquisition, Taihan has strengthened its capabilities in both intra-array and export cable installation for offshore wind projects, while also establishing a system capable of executing long-distance interconnections and HVDC (High Voltage Direct Current) transmission networks. Notably, by operating two CLVs including PALOS, the company has established a dual-track installation system that enables optimal vessel deployment depending on project characteristics and installation environments. The Skandi Connector is a high-specification cable laying vessel designed by Damen, a Netherlands-based specialist shipbuilder, and previously operated by Norway’s DOF Group, a global marine engineering company. The vessel has been deployed in 27 projects, installing approximately 1,300 km of submarine cable, demonstrating proven safety and operational capabilities in global markets, including Europe. Equipped with a DP2 (Dynamic Positioning 2) system, the vessel maintains precise positioning even under changing weather conditions. It also features high-spec installation equipment such as a large carousel and tensioners, enabling installation of export cables, long-distance interconnections, and short-distance HVDC submarine cables. The vessel’s flat-bottom hull enables stable operations in shallow waters, making it particularly suited for Korea’s coastal areas such as the West Sea, where tidal currents are strong and depths are relatively low. With a self-propelled speed of up to 12 knots, it offers superior operational stability and efficiency compared to Cable Laying Barges (CLBs), which require tug assistance. Through this acquisition, Taihan has established a CLV fleet capable of covering the full spectrum of submarine cable installation. This strengthens its vertically integrated system, enabling in-house execution of the entire value chain from design and manufacturing to transportation and installation. In particular, synergies with its Submarine installation subsidiary, Taihan Ocean Works, are expected to enhance turnkey competitiveness and expand project execution capabilities. This investment is particularly significant amid surging global demand for large-scale cable laying vessels driven by the expansion of offshore wind and increased cross-border grid investments. By securing a high-spec CLV available for immediate deployment instead of newbuild construction, Taihan improves responsiveness and operational stability while proactively addressing supply-demand imbalances in installation vessels. It is also expected to reduce reliance on foreign vessels, thereby contributing to the stability of domestic power grid projects and strengthening energy security. The company also plans to expand business opportunities through both fleet operations and vessel chartering. A company official stated, “With the additional CLV, we have established a system capable of executing both offshore wind projects and long-distance interconnections simultaneously. Leveraging PALOS and Skandi Connector, we will continue to strengthen our competitiveness in the global submarine cable market through stable project execution.” Taihan signed the vessel purchase agreement with DOF on the 14th, and delivery to Korea is scheduled for August.
