In a major boost to South Korea’s offshore wind infrastructure, Taihan Cable & Solution today confirmed a KRW 181.6 billion (EUR 113 million / US$131 million) turnkey contract. Taihan Cable will design, manufacture, transport, and install more than 100 km of inter-array submarine cables for the 532 MW Anma Offshore Wind Farm, poised to become South Korea’s largest offshore wind project.

More on the project
Located off the Anma Archipelago in Yeonggwang-gun, Jeollanam-do, the 532 MW Anma Offshore Wind Farm spans approximately 83.9 million m² of sea. Once operational, it will generate around 1,400 GWh annually, enough to supply approximately 1.4 million households. The project was part of the 1.9 GW offshore wind capacity award announced by the South Korean government at the end of 2024.
Taihan will fabricate the submarine cables at its newly completed Dangjin Submarine Cable Plant 1. Installation will be handled by its own vessel, PALOS, which is also South Korea’s only dedicated cable-laying vessel. It also recently served at the Yeonggwang Nakwol offshore wind farm.
Why the Anma Offshore Wind Project matters
This contract signals both industrial leadership and strategic infrastructure scale-up. The deal reinforces the company‘s end-to-end capabilities in inter-array cable projects while actively strengthening South Korea’s domestic supply chain for offshore wind.
Additionally, Taihan also initiated Submarine Cable Plant 2, capable of producing 640 kV HVDC and 400 kV HVAC cables, with operations expected in 2027.
Taihan’s acquisition of OceanC&I, an offshore cable-installation specialist, also boosts its in-house engineering, installation, and maintenance capability further. It undoubtedly makes it one of the few firms worldwide with full submarine cable competency.
What lies ahead
Construction and cable installation at the 532 MW Anma Offshore Wind Farm in South Korea are scheduled through end of 2028, marking a critical phase in Anma’s progression toward full commissioning. As part of South Korea’s West Coast Energy Highway, the project will feed clean power into the national grid and set a new benchmark for domestic offshore wind infrastructure.
The announcement also comes as the imminent offshore substation work that has been contracted to HBA Future Energy comes along. Also ahead is the spinning of foundations, tower installation, and grid tie-ins. This will undoubtedly make the 532 MW Anma Offshore Wind Farm in South Korea a model for rapid, integrated offshore wind project buildout in Asia.
