ClassNK has unveiled the 'Part A Guidelines for Ships Using Alternative Fuels (Edition 3.0.1)', which provides detailed interpretations of safety protocols for methyl and ethyl alcohol-fuelled vessels.
This newly released document offers insights into the necessary plans, documents, and class survey items essential for these specific types of ships.
Background on alternative fuel guidelines
The comprehensive 'Guidelines for Ships Using Alternative Fuels' outline safety protocols essential for vessels using non-traditional fuels. These guidelines aim to mitigate risks posed to ships, crew, and the environment by detailing requirements for installations, safety devices, and control systems.
The guidance is divided into four distinct sections: Part A focuses on Methyl/Ethyl Alcohol, Part B on LPG, Part C on Ammonia, and Part D on Hydrogen. In light of the growing number of alcohol-fuelled ships being produced both locally and globally, this updated version seeks to clarify frequently queried requirements in Part A, thereby offering enhanced support to industry stakeholders involved in such initiatives.
Highlights of part A (Edition 3.0.1)
The guidance benefits from experiences gathered during design review processes and aims to better clarify
The latest edition of Part A introduces supplementary information on vital design subjects that have gained considerable attention in the shipbuilding domain.
The guidance benefits from experiences gathered during design review processes and aims to better clarify the safety requirement interpretations for alcohol-fuelled ships. In line with current trends, the document also addresses planned updates to the IMO Interim Guidelines, which underpin Part A's basis.
These updates are set for review at the 12th session of the IMO Sub-Committee on Carriage of Cargoes and Containers (CCC 12) scheduled for September 2026. ClassNK intends to incorporate relevant changes from these discussions into Part A as necessary.
Supporting the transition to alternative fuels
As part of the 'ClassNK Transition Support Services', the organisation remains committed to aiding clients in the transition to zero-emission vessels through the issuance of safety guidance and design standards for alternative-fuelled ships.
The newly published guidelines can be accessed and downloaded through ClassNK’s website, under the 'Guidelines' section of My Page, post-registration.
