CIMAC WG 7 Fuels has released a new guideline titled ‘Frequently Asked Questions (FAQ) – ISO 6583:2024: Methanol as a Fuel for Marine Applications – General Requirements and Specifications’ which addresses 32 frequently asked questions across six sections.
With the publication of ISO 6583:2024 in November 2024, the first standard for methanol as a marine fuel, numerous questions are expected to arise. Consequently, ISO/TC 28/SC4/WG18 requested CIMAC WG 7 Fuels to support the standard and the marine industry by creating a FAQ document. CIMAC WG 7 Fuels formed a sub-group comprising industry experts from both CIMAC and ISO working groups. The guideline was finished within four months.
Sub-group leader Julia Svensson, MAN Energy Solutions, said: “Methanol is a new fuel in the marine industry, and it is crucial to provide clear answers and clarifications. The guideline includes a schematic illustration to explain how to sum up methanol impurities and water content, which can be challenging. It also addresses the differences between the three methanol grades and the necessity of having a standard. This guideline is an excellent complement to ISO 6583:2024 and was made possible thanks to the collaboration of my colleagues.”
