ClassNK awards AiPs for SDARI’s green fuels powered vehicle carriers


ClassNK has issued Approvals in Principle (AiPs) for three vehicle carrier designs developed by Shanghai Merchant Ship Design & Research Institute (SDARI).

The first AiP acknowledges an ammonia ready LNG dual fueled vehicle carrier with a capacity of 7,000 CEU, a significant first in China’s independently developed design. For the ship with the dimension of LOA 199.99m x B 38m × D 37m, Draft 8.6m, SDARI integrates the GTT MARK III Flex containment system for LNG and ammonia fuel storage to maximize the cargo capacity efficiently.

Furthermore, ClassNK has granted AiPs for both methanol dual fueled and ammonia dual fueled vehicle carriers, each with a capacity of 10,000 CEU, which is envisioned to lead the development of ultra-large vehicle carriers.

SDARI has created these three models exemplify the new generation of green vehicle carriers, adaptable to various alternative fuel options and catering to future market demands. ClassNK has engaged in SDARI’s development projects, and carried out its review in accordance with the relevant standards, including its latest structural rules Part C and Guidelines for Ships Using Alternative Fuels. Marking the AiPs as the milestone, ClassNK is committed to further providing expertise to assist the design firm’s initiative in expanding the industry’s pathway for the transition to decarbonization.

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.
