ClassNK has released the fourth version of its Guidelines for Gas Fuelled Ships.
The new guidelines provide up-to-date information on key design features relating to bunkering, hull structure, fire safety, and explosion prevention measures for gas-fuelled vessels, as the industry increasingly turns toward the use of cleaner fuels such as LNG to help curb their emissions.
The International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code), scheduled to come into force on 1 January 2017, will introduce a wide range of safety regulations with far-reaching implications for gas-fuelled vessels. The new guidelines build on the structural requirements set out in the first version of the guidelines published in 2009, with recent technological developments including amendments to the IGF Code and discussions on safety requirements regarding the use of methanol/ethanol as fuel.
Other new updates cover areas such as safety measures for vessels not originally built to use LNG as a fuel. Vessels that meet the criteria for conversion to operate as LNG-fuelled vessels are fixed with the LNG Ready notation in accordance with the new guidelines.
