Taihan Secures Advanced Submarine Cable Installation Technology, Strengthening Construction Competitiveness
- Completes four-year joint development with the KERI and executes technology transfer
- Internalizes core installation technology immediately applicable to offshore wind farms
- Signs comprehensive MOU for lifecycle-wide submarine cable R&D cooperation to accelerate market expansion
Taihan has secured a key technology that enhances its competitiveness in submarine cable installation.
On February 11, Taihan announced that it signed a technology transfer agreement with the Korea Electrotechnology Research Institute (KERI) for a new submarine cable installation method known as the “J-Tubeless.” The agreement marks the culmination of approximately four years of joint development between the two organizations, enabling Taihan to internalize a core installation technology that can be immediately deployed in offshore wind farm projects.
The transferred “J-Tubeless” applies to the stage in which submarine cables transported by cable-laying vessels are raised to the lower structure of offshore wind turbines (riser installation). Conventionally, metallic conduits (J-Tubes) are installed at the turbine foundation to guide and protect cables during this process. In contrast, the new system utilizes a flexible protective structure and dedicated support devices, enabling stable cable protection and installation without the need for separate metallic conduits.
The technology was developed through a government-supported research project on offshore wind submarine power network construction, jointly conducted by Taihan and KERI with support from the Ministry of Climate, Energy and Environment and the Korea Institute of Energy Technology Evaluation and Planning (KETEP).
By reducing constraints in the cable riser installation process, the system enables faster installation and cost efficiencies while enhancing both construction productivity and long-term operational reliability, making it optimized for offshore wind environments.
Through the technology transfer, Taihan has secured rights to this method and strengthened its differentiated capabilities encompassing design, manufacturing, and installation. This advancement reinforces the company’s competitive positioning in the global offshore wind market. Taihan plans to apply the technology to upcoming projects to further enhance installation competitiveness and expand its utilization in both domestic and international markets.
In addition to the technology transfer agreement, Taihan and KERI signed a Memorandum of Understanding (MOU) for comprehensive cooperation in submarine cable technology development. Under the MOU, the two organizations will pursue joint research and development across the full lifecycle of submarine cables, including cable characteristics and product evaluation, installation and maintenance technologies, as well as post-laying diagnostic and monitoring solutions, with a commitment to sustained mid- to long-term collaboration.
A Taihan representative stated, “Securing this technology is highly significant in that it elevates our submarine cable installation competitiveness to the next level. Building on our collaboration with KERI, we will continue advancing core submarine cable technologies and accelerate our expansion in the offshore wind market.”
