ClassNK has issued an approval in principle (AiP) for a methanol fuel tank design concept developed by SRC Group.
The certification demonstrates its feasibility from regulatory and safety perspectives. With the growing adoption of alternative fuels such as methanol in the maritime industry, the development of safe and efficient fuel storage solutions has become increasingly important. The design concept enables efficient utilisation of fuel tank capacity while meeting safety requirements by eliminating the need for additional structural space for a cofferdam.
ClassNK carried out a design review of the design concept based on Part A Guidelines for Ships Using Methyl/Ethyl Alcohol as Fuels (Edition 3.0.0) of the Guidelines for Ships Using Alternative Fuels. ClassNK issued AiP upon confirming the feasibility of key design, including the arrangement of methanol fuel tanks and fuel supply systems, in terms of regulatory compliance.
Furthermore, in anticipation of future application to actual vessels and to facilitate the final approval process, ClassNK presented the concept overview and key technical considerations to the Panama Maritime Authority prior to the issuance of the AiP and received its acknowledgment.
