With the maritime industry facing up to the challenges set by ever-more ambitious emissions reduction targets, Wärtsilä is committed to helping our customers achieve regulatory compliance while maintaining profitability and continuously improving vessel performance.
Methane is the main component of LNG and a highly potent greenhouse gas, with a global warming potential many times that of carbon dioxide. When LNG is burned as fuel, most of the methane is consumed in the energy conversion process, but any unburned methane escapes into the atmosphere, and this is known as methane slip.
Methane slip from Wärtsilä dual-fuel engines has been cut by 75% over the past 25 years, and further advances will continue to reduce methane slip over the coming years. These engine advances and emission abatement improvements mean that our gas engines offer a clear advantage over diesel engines in terms of emissions.
With an easy to access control software upgrade, vessels powered by the Wärtsilä 34DF engine can significantly reduce their greenhouse gas (GHG) emissions. The upgrade is based on adaptive combustion phasing control, which optimises engine behaviour according to the ambient and operating conditions.
