LS Cable & System and LS Marine Solutions have been chosen as the preferred bidders for the supply and installation of underwater cables for the 1GW Haesong offshore wind project in Jeonnam, South Korea.

On May 19, the companies announced their plans to execute the project using a turnkey system that encompasses everything from production to installation. They will supply and install all underwater cables for both external and internal networks, contributing to the establishment of a large-scale offshore wind infrastructure.

The Haesong offshore wind project aims to develop two 504MW complexes near Heuksando Island in Jeonnam, totaling 1GW. Copenhagen Infrastructure Partners (CIP), a global green energy investment and development firm, oversees the entire project, while its subsidiary, Copenhagen Offshore Partners (COP), is responsible for development.

Industry experts note that collaboration experience with global developers and a proven track record in project execution are critical factors for the stability of large-scale underwater cable projects. LS Cable & System and LS Marine Solutions have built their capabilities in underwater cable supply and installation through various domestic and international projects in partnership with global developers, including CIP.

The choice of a domestic supply and installation system by a global developer is seen as significant for the localization of key offshore wind infrastructure and the strengthening of supply chain stability.

In offshore wind projects, the ability to connect turbines to the land-based power grid reliably through underwater cables has emerged as a key competitive advantage that affects the overall project credibility.

Before the final contract, the two companies plan to detail the supply schedule and technical requirements to ensure a stable supply chain for key materials, enhancing the overall project stability and predictability.

This project also represents a practical application of a collaborative model between LS Cable & System's underwater cable technology and Korea Electric Power Technology's power system and EPC design capabilities. LS Cable & System, Korea Electric Power Technology, and CIP will pursue joint research and development for underwater cable operation and maintenance, localization expansion, and supply chain collaboration.

Park Seung-ki, head of the domestic sales division at LS Cable & System, stated, "Underwater cables are becoming increasingly important infrastructure for national power grids and energy security. We will leverage our turnkey competitiveness with LS Marine Solutions to ensure stable project execution and enhance the competitiveness of the domestic offshore wind supply chain."
