Classification society ClassNK on Thursday (18 December) said it has issued approval in principle (AiP) for a concept design for a bulk carrier that is ready for multiple alternative marine fuels, including ammonia, methanol and LNG, as well as onboard carbon capture and storage (OCCS), developed by Oshima Shipbuilding.
The certification confirmed the feasibility of the vessel from regulatory and safety perspectives.
ClassNK has published Annex 1 Alternative Fuel Ready (Edition 3.0.1) of the Guidelines for Ships Using Alternative Fuels, which summarises the requirements for adding class notations to ships that do not use alternative fuels at the time of construction but are designed and partially equipped to accommodate such fuels in the future.
Similarly, requirements for a ready notation to onboard CO2 capture and storage systems (OCCS) are included in the Guidelines for Onboard CO2 Capture and Storage Systems (Edition 2.0).
“ClassNK reviewed the concept design of the vessel based on above-mentioned guidelines. Upon confirming compliance with the prescribed requirements, ClassNK issued AiP,” the classification society said.
