Korean Register (KR) has granted Approval in Principle (AIP) to a newly developed 50,000-cbm LPG carrier, jointly designed with HD Hyundai Heavy Industries (HHI). The AIP was presented on September 16 at Gastech 2026 in Bangkok, Thailand.
LPG carriers require precise control of cargo temperature and pressure to keep LPG cargo stable throughout storage and transport. Achieving both safety and cargo-loading efficiency in LPG transport calls for advanced engineering at every stage of design and construction.
The carrier features Type A independent tanks, which store LPG cargo separately from the ship's hull structure, ensuring stable storage and transport of the gas at low temperatures.
Under the joint development project, HHI carried out the concept and basic design, while KR reviewed the design for compliance with applicable international standards and gas carrier regulations before issuing the AIP.
Hong-ryul Ryu, Senior Executive Vice President and CTO of HHI, said:
"Rising LPG trade volumes and increasingly diverse shipping routes have fueled growing interest in mid-size LPG carriers that offer efficiency and port accessibility distinct from larger vessels. This 50K-class carrier was developed in response to these market shifts and evolving transport needs. We will continue to diversify our vessel portfolio to stay ahead of emerging market demand and strengthen our competitiveness."
Kyujin Yeon, Executive Vice President of KR, said:
"Through this AIP for the 50K LPG carrier, KR has addressed the technical requirements of the mid-size LPG carrier market and laid the technical groundwork for developing new vessel types. We will continue to support the development of safe, efficient vessel technologies through ongoing technical collaboration with shipyards."
