ClassNK has issued Approvals in Principle (AiPs) for four cutting-edge ship designs developed by Marine Design & Research Institute of China (MARIC).
The four designs – a 210k methanol dual-fuelled bulk carrier, a 210k ammonia dual-fuelled bulk carrier, a 210k LNG dual-fuelled bulk carrier, and an 88k LPG dual-fuelled very large gas carrier – represent MARIC’s approach to offer a range of environmentally friendly alternatives for the industry transitions towards the ultimate goal of net-zero emissions.
ClassNK follows Guidelines for Ships Using Alternative Fuels
For these accomplishments, ClassNK conducted the verification in line with relevant rules corresponding to respective ship type, including its Guidelines for Ships Using Alternative Fuels.
ClassNK is proud to have completed the design review for these Approvals in Principle (AiPs)"
Mr. Fumihiko Higashi, President, Headquarters of ClassNK (China) said “ClassNK is proud to have completed the design review for these Approvals in Principle (AiPs). We believe this certification, stemming from the collaborative efforts of MARIC and ClassNK will serve as a testament to the integrity of these diverse designs.”
Fumihiko Higashi adds, “More importantly, it acts as a catalyst in accelerating the uptake of alternative fuels onboard, aligning with global environmental goals.”
Approval in Principle (AiP)
At the initial stage of designing or before the specific target ship to be implemented is decided, the design is examined based on the existing regulations, such as international conventions and ship classification rules, and an Approval in Principle (AiP) is issued as proof of conformity with requirements.
It also prevents rework of regulatory aspects in the post-process, shortens the examination time at the time of class registration, and can be used as a technical basis for external appeal of the design status.
