ClassNK approves KHI’s LPG fuel supply system design

Classification Society ClassNK granted an approval in principle (AiP) to Kawasaki Heavy Industries (KHI) for their LPG fuel supply system.

The AiP is based on ClassNK’s Rule Part N which adopts IGC Code and its Guidelines for Ships Using Low-Flashpoint Fuels.

Utilizing the know-how from the design and construction of LPG carrier, LNG carrier, and LNG fueled ships as well as the design and production of marine engines, KHI has developed the LPG fuel supply system.

In consideration of LPG fuel’s property and the related rules, ClassNK has carried out the verification on the system from the viewpoint of minimizing risks to vessels, crew, and the environment.

Following confirmation that the design of KHI’s LPG fuel supply system met the prescribed standards, ClassNK has issued the AiP.

The design features a cyclical system design that is compatible with propane and butane and circulates LPG in a pressurized state capable of usage at normal ambient temperature. It also establishes a safe control system by implementing risk assessment based on the IGC code, and the system configuration is applicable to merchant ships other than LPG carriers.
