Hydrogen Ship Technology Center, PNU in collaboration with Samwoo MCP, 

has secured an AIP for LNG Fuel Tank by ABS

A liquefied natural gas(LNG) fuel tank for ships, co-developed by Pusan National University’s Hydrogen Ship Technology Center, led by Director Jae-Myung Lee, professor of Naval Architecture & Ocean Engineering, and Samwoo MCP, headed by CEO Oh-Kyun Shin, has received an Approval In Principle(AIP) for safety and design suitability from the American Bureau of Shipping(ABS).

The “AIP Certificate Award for the 0.7m3 LNG Fuel Tank” was held at the BK Lounge of Pusan National University on September 20th, where SamWoo MCP received the AIP certification, and in attendance was Darren Leskoski, Vice President of ABS for the Far East Asia region.

An ‘AIP’ is a crucial milestone that confirms the suitability and adequacy of the design. It serves as a technical benchmark in the design process, enabling companies to progress towards bringing their products to the market.

The certified LNG fuel tank in question is designed to store liquefied hydrogen between its inner and outer tanks. It utilizes proprietary technology to effectively reduce heat transfer to the inside of the tank by incorporating low-density foam and thin-film multilayer insulation materials. This innovative approach establishes a vacuum environment within the tank.

To address the issue of vacuum loss during ship operation, the design ensures that insulation performance is maintained even as the vacuum level decreases. This feature ensures safety against potential internal pressure increases.

This newly developed fuel tank will undergo testing in an ultra-low temperature environment at the Pusan National University Hydrogen Ship Technology Center Test Building in Uam-dong, Nam-gu, Busan, set to open on November 15th. Moreover, there are plans to expand and further develop these fuel tanks for use in larger ships.
