The successful deployment of the KC-2C cargo containment system on a commercial LNG carrier marks a significant step toward South Korean technological self-reliance in the global shipbuilding industry.
Purpose and Features of KC-2C
The KC-2C is a Korea-style cargo containment system developed by Samsung Heavy Industries (SHI) specifically to end the domestic shipbuilding industry’s reliance on foreign technology for LNG cargo tanks.
- Technological Self-Reliance: Historically, Korean shipbuilders, despite their global dominance in LNG carrier construction, have had to rely on and pay significant royalties to foreign firms (like France’s GTT) for this critical technology. The KC-2C aims to localize this core component.
- Design Improvements: Compared with existing tanks, the KC-2C features improvements in the design and construction method of the secondary barrier.
- Performance Benefits: This new design offers enhanced airtightness, stability, and excellent insulation performance, which is vital for safely storing Liquefied Natural Gas (LNG) at cryogenic temperatures.
- Manufacturing Efficiency: SHI utilized a self-developed Laser High-Speed Welding Robot for the membrane welding work, which significantly improves production efficiency.
Commercial Deployment and Future Plans
The system has moved from demonstration to commercial operation, signaling its readiness for market acceptance.
- First Commercial Voyage: The KC-2C was installed on a 7,500m^3 LNG carrier, built in collaboration with Korea Line Corporation. The vessel was delivered this month and completed its maiden voyage, transporting LNG from Tongyeong to the Aewol LNG terminal in Jeju.
- Prior Demonstration: The system was previously mounted on SHI’s multipurpose LNG bunkering barge, the Green Nuri, in October last year for extensive demonstrations, including offshore LNG bunkering and cooling tests.
- Market Ambition: Samsung Heavy Industries plans to expand the use of the KC-2C by seeking its evaluation and adoption through the retrofit and newbuilds of larger 174,000m^3 LNG carriers, which are the standard size for long-haul international transport.
