July 15, 2025, by Adnan Memija

Taihan Cable & Solution has completed the installation of export cables for the 364.8 MW Yeonggwang Nakwol offshore wind project in South Korea.

The export cable installation, covering two 28-kilometre lines and carried out by Taihan’s cable-laying vessel (CLV) PALOS, was performed 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, according to the company.

The installation of the inter-array cables, also produced by Taihan, is scheduled to commence after July.

Developed by Nakwol Blue Heart, the Yeonggwang Nakwol offshore wind project is located near Songido, Nakwol-myeon, Yeonggwang-gun, Jeollanam-do, off the coast of South Korea.

With a total project cost of KRW 2.3 trillion (approximately EUR 1.42 billion) and a capacity of 364.8 MW, the wind farm is expected to generate enough electricity to power about 250,000 households year-round upon completion. The overall project progress has now surpassed 50 per cent, said Taihan.

PALOS, introduced in November 2023, is a specialised 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.

The vessel is a hybrid model capable of operating in both Dynamic Positioning Class 2 (DP2) mode and Anchoring mode. It also features a flat-bottom design that allows independent access to very shallow coastal areas, enabling all-weather deployment across diverse marine environments.

“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,” a Taihan official stated.
