Who we work with
- We are a working group of experienced specialists within marine fuels, represented by the major players, and our goal is to prepare recommendations and make tools for the industry on how to operate on fuel, and choose fuels that will ensure safe operation of the diesel engines.
- Support the ISO 8217 Fuel Standard Group.
- Coordination with sister CIMAC WGs, such as USERS, Lube Oil and Emissions.
