Designed with EEDI regulations, low vessel emission & operational flexibility in mind
The Wärtsilä X72 has been designed as a main engine for Suezmax tankers, Capesize bulk carriers, as well as Panamax and Sub-Panamax container vessels.
The Wärtsilä X72 is having a cylinder bore of 720 mm and its power output is in the 8,480 to 28,880 kW range. It comes in 4 to 8 cylinder configurations.
The Wärtsilä X72 is fully compliant with IMO Tier II requirements. It can also be equipped with a SCR catalyst to meet IMO Tier III NOx emission levels, and a scrubber to reduce SOx emissions to 0.1% even with high sulphur fuels.
The introduction of the EEDI index also puts an emphasis on CO2 emissions and total vessel efficiency. The internal engine efficiency of Wärtsilä X72, and the possibility to apply various Power Take Off (PTO) arrangements for onboard electricity production, make it easy for shipyards to meet these new requirements
