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, according to the company's release.
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.
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.
