An Approval in Principle has been granted by ClassNK to Nippon Yusen Kabushiki Kaisha (NYK Line) for its ammonia bunkering vessel (ABV). This marks the first time ClassNK has awarded an AiP to an ABV.
Developed by NYK Line, the ABV will be used as a bunkering vessel for ammonia-fueled vessels which are currently growing in popularity due to the fuel not emitting CO2 .
During the development stage, NYK reworked its own drawings by introducing 3D models at the concept design stage. This enabled the company to add specifications into the design which incorporated safety measures for the use of ammonia, including hazardous areas and escape routes which were based on prior risk assessments.
The design review of NYK’s ABV was conducted by ClassNK in line with the company’s Part N of Rules for the Survey and Construction of Steel Ships incorporating the IGC Code. Once ClassNK had confirmed the vessel adhered to all rules and regulations, an AiP was issued for the design concept.
