The technologically advanced Wärtsilä 46F can be run on either heavy fuel oil (HFO), marine diesel oil (MDO), or on light diesel when being operated within strict coastal or port emissions areas. This fuel switching can take place smoothly and without power interruption across all engine loads. This flexibility enables the operator to select the fuel according to price, availability, and the need to meet local emissions regulations.
The Wärtsilä 46F engine is fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention.

If you are considering a switch to low-carbon fuel, methanol is an attractive option. Green methanol has the potential to be carbon free, and it meets current and future emissions targets in terms of NOx, SOx and particulates.
