Taihan Strengthens Turnkey Competitiveness with Acquisition of Offshore Cable Installation Specialist ‘OceanC&I’- OceanC&I brings extensive expertise in submarine installation and a solid record of successful offshore projects- Enables internalization of full submarine cable value chain: design, manufacturing, transportation, installation, and maintenance- Accelerating preparations for the "West Coast Energy Highway" and reinforcing global market leadershipTaihan has taken a major step forward in enhancing its turnkey project capabilities by acquiring Ocean Construction & Installation (OceanC&I) a leading offshore cable installation and engineering company. Taihan acquired 100% of OceanC&I’s shares from CEO Yoon Jong-moon and other stakeholders. The signing ceremony, held at Hoban Park 2 Center, was attended by key executives from both companies, including Taihan Vice Chairman Song Jong-min and OceanC&I CEO Yoon Jong-moon. Established in 2008, OceanC&I has specialized in submarine cable laying and engineering, with deep expertise in offshore construction solutions. The company possesses robust human and material infrastructure and has completed numerous domestic and international offshore wind power projects, including the Southwest Offshore Wind Farm in Korea, as well as projects in Venezuela and the Philippines. OceanC&I also has broad experience in submarine cable protection and maintenance services. Of particular note is its proven track record in operating cable-laying vessels (CLVs). This expertise is expected to further enhance the operational efficiency of Taihan’s own CLV, the PALOS, Korea’s first dedicated cable-laying vessel, which was launched in November 2023. The PALOS recently demonstrated its performance by successfully completing the full export cables installation for the Yeonggwang Nakwol Offshore Wind Farm, contributing to the stability of Korea’s offshore wind supply chain. This acquisition enables Taihan to internalize key competencies across the entire submarine cable value chain—from design and manufacturing to transportation, installation, engineering, and maintenance—strengthening its edge in turnkey projects. Following the acquisition, Taihan plans to actively invest in advanced equipment and recruit top-tier talent to further enhance its credibility and expertise in the offshore construction sector. By reinforcing its technical capabilities, the company aims to position itself as a trusted global leader in marine installation. Leveraging this enhanced competitiveness, Taihan intends to pursue high-voltage direct current (HVDC) and other turnkey projects both domestically and globally. With only a limited number of companies worldwide capable of both producing and installing submarine cables, this strategic move is expected to significantly elevate Taihan’s global market presence and unlock new business opportunities. A Taihan official commented, “This acquisition allows us to fully internalize submarine cable installation capabilities and strengthen our ability to manage turnkey projects. We are committed to meeting the growing global demand for submarine cables while playing a central role in strategic initiatives such as the ‘West Coast Energy Highway’.” Taihan continues to strengthen its capabilities in the offshore wind and submarine cable sectors. In June, the company completed its first submarine cable plant in Dangjin, capable of producing both internal and export cables for offshore wind. On July 16, Taihan approved an investment in its second plant, which will produce 640kV HVDC and 400kV HVAC cables, with construction set to begin within the year and operations expected in 2027.

The cable-laying vessel PALOS is currently carrying out the export cable installation for the Yeonggwang Nakwol Offshore Wind Project.    Taihan’s CLV ‘PALOS’ Successfully Completes Export Cable Installation for the Yeonggwang Nakwol Offshore Wind Project - Korea’s only CLV demonstrates performance in the challenging West Sea region- Hybrid vessel with selectable DP2 and Anchoring modes maximizes operational efficiency- Taihanprepares to join the ‘West Coast HVDC Energy Highway’ based on turnkey competitiveness   Taihan’s cable-laying vessel (CLV), PALOS, has successfully completed the installation of export cables for the Yeonggwang Nakwol Offshore Wind Project, demonstrating its exceptional performance. The project, located near Songido, Nakwol-myeon, Yeonggwang-gun, Jeollanam-do, is a large-scale initiative to develop a 364.8MW wind power complex. With a total project cost of KRW 2.3 trillion, the facility will generate enough electricity to power approximately 250,000 households year-round upon completion. The overall project progress has now surpassed 50%.  This project marks the first deployment of PALOS since its acquisition by Taihan. The export cable installation, covering two 28km lines, was carried out in two phases: the first phase took place over two weeks in mid-May, and the second phase began in late June and was completed last week. The installation of inter-array cables, also produced by Taihan, is scheduled to commence after July.  PALOS, introduced in November 2023, is a specialized cable-laying vessel acquired to secure Taihan’s turnkey competitiveness, spanning production, transportation, installation, and maintenance of submarine cables. As Korea’s only CLV, it was purpose-built from the design stage for submarine cable installation. With a top speed of 9 knots under its own power, PALOS offers installation speeds five to six times faster than CLBs (Cable Laying Barges) that rely on tugboats, and maintains stability even in adverse weather and tidal conditions. The vessel is a hybrid model capable of operating in both DP2 (Dynamic Positioning Class 2) mode, which automatically and precisely controls the vessel’s position, and Anchoring mode, which fixes the vessel using anchors as needed. DP2 mode is used for deep waters requiring high-precision installation, while anchoring mode, which consumes less fuel, is employed in shallow waters with minimal tidal influence, ensuring both efficiency and cost-effectiveness. Additionally, unlike conventional vessels, PALOS features a flat-bottom design that allows independent access to very shallow coastal areas, enabling all-weather deployment across diverse marine environments. It is particularly recognized for delivering optimal performance in the West Sea, where shallow depths and strong currents make cable installation highly challenging. A Taihan official stated, “PALOS has proven both its stability and installation capabilities by successfully completing cable laying in the demanding West Sea region. Leveraging our turnkey competitiveness from production to installation, we anticipate creating diverse opportunities in upcoming large-scale offshore wind projects and the West Coast HVDC Energy Highway.” Meanwhile, in June, Taihan completed the comprehensive construction of its first Dangjin submarine cable plant, capable of producing both export and inter-array cables for offshore wind power. In the second half of the year, the company plans to commence construction of its second plant, which will produce 640kV-class HVDC submarine cables and cables for the extra-long continuous export cable, thereby strengthening production capacity to participate in the West Coast HVDC Energy Highway project.​
