ClassNK has issued an Approval in Principle (AiP) for a design concept of the ammonia fuel bunkering boom, which is jointly developed by Nippon Yusen Kabushiki Kaisha (NYK Line) and TB Global Technologies Ltd.
This is the world’s first AiP certification for the design of a bunkering boom for ammonia fuel.
Ammonia fuel utilisation
As ammonia fuel utilisation is expected in shipping for decarbonisation, bunkering vessels that supply fuel to ships and related equipment will play an essential role in the supply chain.
On the other hand, due to the novelty, it can be difficult to confirm the safety of some equipment by applying existing rules.
Guidelines for Technology Qualification
ClassNK is providing a risk-based approach to safety assessment for the implementation of new technology
Targeting such new technologies, ClassNK has issued the ‘Guidelines for Technology Qualification’ that define a certification process to demonstrate that an acceptable level of safety, equivalent to that of technologies designed under existing rules and standards, has been verified.
Through the guidelines, ClassNK is providing a risk-based approach to safety assessment for the implementation of new technology.
Bunkering boom design
ClassNK carried out a drawing review of a basic design of the bunkering boom based on part N of its ‘Rules and Guidance for the Survey and Construction of Steel Ships’ for ships carrying liquefied gases in bulk, and conducted a review of documents required by the ‘Guidelines for Technology Qualification’. Upon confirming they comply with the prescribed requirements, ClassNK issued the AiP.
ClassNK will continually strive to contribute to advanced decarbonisation initiatives through safety assessments and more.
