ClassNK has awarded an approval in principle (AiP) for the design of a prismatic ammonia fuel tank (IMO Type B independent tank) for containerships developed by Planning and Design Center for Greener Ships (GSC).The Type B tank developed by GSC has been designed to ensure safe storage of ammonia and to minimize the reduction in the number of cargo containers due to the placement of fuel tanks in consideration of operational needs.Furthermore, the shape of the storage space for the tank has been simplified from the typical bench corners for container carriers…

Technical inquiries to SRC Group ramped up after it received Approval in Principle (AIP) for a concept which ‘reinvented methanol fuel storage’ on board ships. Delivering the answers has seen technical talk converting into project discussions        ‘Green’ methanol has the ability to one day run vessels almost emission-free, and commercial shipping increasingly investigates. Derived today principally from natural gas, methanol is nonetheless available, relatively easy to handle and predictable.
