Front cover: ClassNK releases “Guidelines for Ships Using Alternative Fuels (Edition1.1)”.

ClassNK has released its “Guidelines for Ships Using Alternative Fuels” including updates on the safety requirements for ships using ammonia as fuel.

Ammonia has captured attention as a zero carbon fuel. Appropriate safety measures are required for ammonia as it is toxic to humans and corrosive to materials, while specific international standards for the use of ammonia as a marine fuel have not yet been established. ClassNK has described the requirements for installation, controls, and safety devices of an ammonia fuelled ship to minimising risks for the ship, crew, and the environment, and added it to the guidelines.

In addition, ClassNK has revised the existing “LNG-Ready” notation to “Alternative Fuel Ready,” and outlined the requirements for the new notation indicating that a ship is designed and partially equipped for future use of alternative fuels.

The guidelines are reflecting the current technology trend and will be updated regularly along with developments of new technologies and research.

The guidelines are available to download via ClassNK’s website for those registered for the ClassNK “My Page” service.
