DNV AiP for ammonia-fuelled gas carrier

Created with collaborators including MAN Energy solutions, Babcock International and the Norwegian Maritime Authority, the design has been awarded the AiP based on the special features notation (GF NH3) under DNV’s new rules for the use of ammonia as fuel in gas carriers.

“Obtaining an AiP from DNV for ammonia-fuelled vessels is the first step in preparing Navigator Gas to meet the future demands of our customers and to reduce our carbon footprint through lower greenhouse gas emissions,” said Paul Flaherty, technical advisor to Navigator Gas.

“Using ammonia as fuel is one of the options we are pursuing, along with carbon capture and storage, carbon offsetting and improved vessel optimisation,” he added.

Torgeir Sterri, senior vice president, regional manager West Europe, DNV Maritime recognised that decarbonising shipping was the most challenging and significant issue faced by shipowners this decade. ”This is why we have created class notations and guideline that give them the flexibility to find the path that fits their operations and business,” he said.

Babcock brings a wealth of safety expertise garnered through delivering LPG fuel supply systems whilst MAN Energy Solutions is expecting to make a dual-fuel, two-stroke ammonia engine commercially available for large-scale ocean-going ships by 2024, followed by a retrofit package by 2025.
