Tokyo-based Nippon Kaiji Kyokai, known as ClassNK or NK, a ship classification society, has issued engineering “Guidelines for the issuance of ship fuel gas”. The draft guidelines were compiled based on the IGF Code of the International Maritime Organization (IMO) — International Code of Safety for Ships Using Gases and or Other Low Flash-Point Fuels. The publication would appear to be in response to increasingly stringent IMO emissions controls and recognises the rapidly expanding adoption of liquefied natural gas (LNG) as an alternative maritime fuel. Currently only in Japanese, the English version is expected to be published in March.
