What's Happening?
The American Bureau of Shipping (ABS) has granted two approvals in principle (AIP) for advanced cargo handling systems developed by HD Korea Shipbuilding & Offshore Engineering (HD KSOE). These systems are designed for liquefied natural gas (LNG) carriers and ethane carriers. The subcooling refrigeration system, a key advancement, enhances refrigeration efficiency by over 10 percent by using a mixed refrigerant of both gas and liquid. This system supercools LNG to temperatures below -170°C, reducing boil-off gas risks and maintaining cargo integrity during transit. Additionally, HD KSOE has developed an advanced cargo handling and re-liquefaction system for ethane carriers, adaptable to various vessel capacities, aimed at improving operational efficiency and mitigating risks associated with ethane transportation.
Why It's Important?
The approval of these systems by ABS signifies a major step forward in the shipbuilding industry, particularly in the transportation of LNG and ethane. As the demand for these energy resources grows, efficient and safe transportation becomes crucial. The advancements in cargo handling systems not only improve operational efficiency but also contribute to the localization of core technologies within the shipbuilding sector. This development enhances the global competitiveness of HD KSOE and supports the industry's shift towards more sustainable and efficient practices.
What's Next?
HD KSOE plans to continue advancing fundamental technologies to further strengthen its position in the global shipbuilding market. The collaboration with ABS, which began with a memorandum of understanding in late 2024, will likely continue to focus on the development and certification of next-generation ship systems. As the industry evolves, further innovations and approvals are expected to support the growing demand for LNG and ethane transportation.
Beyond the Headlines
The approval of these systems highlights the importance of technological innovation in addressing environmental and operational challenges in the maritime industry. The use of mixed refrigerants and advanced re-liquefaction systems not only improves efficiency but also aligns with global efforts to reduce emissions and enhance sustainability in energy transportation.
