Wärtsilä's 50DF marine engine has been tested and certified to run on ethane (LEG) fuel.
The extensive testing programme was carried out by Wärtsilä in close collaboration with Evergas, owner and operator of seaborne petrochemical and liquid gas transport vessels.
Ethane Boil-off
The capability to efficiently burn ethane boil-off gas as engine fuel significantly reduces the need of gas re-liquefaction during the voyage. This means that less power is needed for the cargo handling, thus providing a more efficient and environmentally sound overall system.
With this technology, ships can meet IMO's Tier III regulations without need of secondary emissions cleaning while using either LNG or LEG as fuel. The engines have the capability to seamlessly switch between LNG, LEG, Liquid Fuel Oil (LFO) or Heavy Fuel Oil (HFO) without the need for any modifications to hardware and with uninterrupted operation.
