The "PALOS" Cable Laying Vessel—Deployed for Major Offshore Wind Projects in Korea​​   Taihan Secures 181.6 Billion KRW Turnkey Contract for Anma Offshore Wind Power Project, Marking Major Progress in Korea’s Offshore Wind Market - Proven Full Turnkey Competence in Submarine Cables: From Design to Production, Transport, and Installation- To Be Manufactured at the Recently Completed Dangjin Submarine Cable Plant 1; Installed by Korea’s Sole CLV, “PALOS”- Extensive Experience and Track Record from Successive Offshore Wind Projects- Expanding 640kV HVDC Production Infrastructure to Prepare for the “West Coast Energy Highway Taihan has once again demonstrated its comprehensive competitiveness in the submarine cable sector by winning a large-scale offshore wind contract. On August 4, Taihan announced the signing of a turnkey contract to supply and install over 100km of inter-array submarine cables for Korea’s largest offshore wind development, the Anma Offshore Wind Power project. The contract, valued at approximately KRW 181.6 billion (VAT included), runs until the end of 2028. The Anma Offshore Wind Power project involves constructing a 532MW wind farm on the west coast of the Anma Archipelago in Yeonggwang-gun, Jeollanam-do, covering an area of 83.9 million square meters. Anticipated annual output is 1,400GWh—enough electricity to power 1.4 million people each year. For this project, Taihan will oversee the entire turnkey process, including the design, manufacturing, transportation, and installation of inter-array cables, which link turbines and connect turbines to offshore substations. As wind farms scale up, cable volumes grow commensurately. All submarine cables will be produced at the recently completed Dangjin Submarine Cable Plant 1. For cable laying operations, Taihan will utilize “PALOS,” Korea’s only cable laying vessel (CLV). Previously, Taihan participated in key domestic offshore wind projects such as Yeonggwang Nakwol and Southwest Offshore Wind, accumulating technological expertise and project execution capabilities. The “PALOS” vessel was deployed for the Yeonggwang Nakwol project, proving its outstanding performance on Korea’s West Coast. A Taihan spokesperson commented, “Leveraging our submarine cable competitiveness built since 2009, Taihan is achieving rapid results in Korea’s offshore wind segment. By consistently strengthening our turnkey capabilities, we aim to contribute to supply chain stability for Korea’s offshore wind expansion and the West Coast Energy Highway, while also enhancing export competitiveness as we actively join growing offshore wind projects in Europe and Asia.” To meet fast-growing domestic and international demand, Taihan is steadily strengthening its production and installation capacity. Submarine Cable Plant 1 will supply both inter-array and export cables for offshore wind, and, as of July 16, Taihan has approved investment in Submarine Cable Plant 2, capable of producing 640kV HVDC and 400kV HVAC cables. Construction on Plant 2 is set to begin this year, with operations targeted for 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.​

​Taihan held a PALOS Commissioning ceremonyTaihan reported on the 24th that the commissioning ceremony for the 6,200-ton class submarine cable laying vessel “PALOS” took place at the pier where its second Dangjin submarine cable plant stands. Being the only offshore wind power cable laying vessel (CLV) in Korea, PALOS has the capacity to carry up to 4,400 tons of submarine cable in a single voyage. The event was attended by around 200 participants, including key local figures such as Governor of Chungcheongnam-do, and Mayor of Dangjin. Representatives from the Ministry of Trade, Industry, and Energy, Korea Electric Power Corporation, Korea Wind Energy Industry Association, as well as various power companies, clients, and partner companies also attended. The event proceeded with an opening performance, followed by welcome and congratulatory speeches, the reading of a prayer for safe voyage, and a champagne breaking ceremony, among other proceedings. Constructed with the explicit purpose of laying submarine cables, PALOS exhibits far superior performance when compared to cable laying barges (CLBs) that were converted from cargo barges. Unlike conventional vessels, PALOS features a flat bottom, allowing it to operate at various sites regardless of water depth. The vessel is also outfitted with cutting-edge features such as Dynamic Positioning 2 (DP2).  Furthermore, as a powered vessel capable of reaching speeds of up to 9 knots, PALOS offers an exceptionally stable and precise approach to laying submarine cables, significantly outperforming CLBs that depend on tugboats and lack the capability to effectively respond to weather variations and currents. “Today's launching ceremony marks South Korea's rise to one of the few countries globally equipped with a CLV, with only about 30 such vessels existing worldwide," said Song Jong-min, Vice Chairman of Taihan. "Palos will not only strengthen Taihan's construction competitiveness but also serve as a crucial strategic asset protecting Korea's offshore wind market from foreign competition" "We will construct additional submarine cable factories and secure larger cable-laying vessels in the future, aiming to emerge as a powerhouse in the global offshore wind industry"
