We have developed this tool for ship owners and operators to calculate the Methane Number of the fuel gas. The calculation result indicates whether or not the given gas quality is suitable for use in Wärtsilä dual-fuel engines. If the entered numbers exceed 100% mol, the amount of CH4 is automatically adjusted.
