ClassNK issues AiP for ammonia-ready LNG-fuelled Panamax bulk carrier

Leading Classification Society ClassNK has issued an approval in principle (AiP) for the design of an ammonia-ready LNG-fuelled Panamax bulk carrier developed by Planning and Design Center for Greener Ships (GSC).

Ammonia is expected to be used as ship fuel for decarbonisation since it does not emit carbon dioxide (CO2) when burned. Meanwhile, taking adequate safety measures are impartial due to its characteristics of being toxic to humans and corrosive against materials, and ClassNK has worked on development of standards and certification.

In 2021, ClassNK published its ‘Guidelines for Ships Using Alternative Fuels’ to minimise the risks related to ammonia-fuelled ships for the ships, crew, and environment by stipulating requirements for installation, controls, and safety devices. ClassNK subsequently issued an AiP for the design of an ammonia-fuelled Panamax bulk carrier developed by GSC in January 2022.

GSC describes the newly developed design as LNG-fuelled but ready for ammonia-fuelled. For the short-term aiming lower CO2 emissions, it will be operated by using LNG fuel. For the long-term aiming toward zero CO2 emissions, it has two scenarios; in the first scenario, it is converted to ammonia fuelled propulsion systems, in the second scenario, it will keep the systems but will switch its fuel from LNG to liquified carbon-neutral methane. The ship is developed as a flexible and efficient solution to enduring the unpredictable period of fuel transition.

ClassNK reviewed the design as an LNG fuelled ship based on its Rule Part GF incorporating IGF Code, and as an ammonia-ready ship based on Concept Design category of its ‘Guidelines for Ships Using Alternative Fuels’ Annex 1 verifying the conformity to their requirements as an LNG-fuelled ship and a future ammonia-fuelled ship, ClassNK has issued an AiP as an ammonia-ready LNG-fuelled ship.
