The company, CG-ENG, and MSC staff engineers worked together to establish a framework of standards and require-ments to address this new emerging technology. The framework, also known as a design basis, drew on a mix of international codes and standards, some very recently developed, that when used together address the major issues and risks posed by using hydrogen, fuel cells, and lithium-ion batteries for vessel propulsion.Standards used in the design basis included: IMOs new International Code of Safety for Ships Using Gases or Other Low-Flashpoint Fuels (IGF Code), fuel cell requirements recently incorporated into the rules for Classification Societies as defined in Title 46 CFR 8.220, industry standards for calculating hazardous areas in IEC-60079, and an ABS Type Approval for 36JANUARY/FEBRUARY 2020FOGHORN'
