Expertise group Wärtsilä has launched its NextDF expertise for a 3rd engine, the Wärtsilä 46TS-DF dual-fuel engine. Whereas working on liquefied pure fuel (LNG), the Wärtsilä 46TS-DF engine with NextDF function reduces methane emissions to lower than 1.4 p.c of gasoline use throughout all load factors, attaining as little as 1.1 p.c in a large load vary. That is almost 3 times decrease than the default methane slip issue of three.1 p.c, specified within the FuelEU Maritime and IMO Lifecycle Tips for Otto-cycle four-stroke dual-fuel engines. By enhancements made to the combustion management, and thru optimising engine efficiency, the brand new function additionally minimises nitrogen oxide (NOx) and CO2 emissions. emissions.
LNG is a crucial transition gasoline because the marine business strives to cut back its carbon footprint. Nevertheless, the primary element of LNG is methane and when burned as a gasoline, a small quantity might not combust correctly, resulting in methane escaping into the environment. Throughout the transport business, the usage of LNG and reducing methane emissions is without doubt one of the handiest methods to lower general greenhouse fuel (GHG) emissions from engines over the following decade, complementing different efforts to cut back CO2 emissions.
“NextDF expertise reduces the environmental affect of vessels that use LNG as gasoline, with out compromising on efficiency or operational stability. Importantly, this makes it simpler for ship house owners to adjust to more and more stringent decarbonisation targets and laws,” feedback Stefan Nysjö, Vice President of Energy Provide, Wärtsilä Marine.
Launched in 2022, the Wärtsilä 46TS-DF engine has a two-stage turbocharging to ship excessive ranges of effectivity and energy density throughout a large operational vary for vessels in all segments of the business. This stage of effectivity reduces gasoline consumption and lowers emissions, whereas being simply retrofittable for sustainable fuels as they grow to be extensively out there. By making use of the NextDF function, the engine can have the bottom methane emissions and GHG emissions within the 1MW+/cylinder energy vary.
The Wärtsilä 46TS-DF with NextDF function was developed as a part of the EU co-funded GREEN RAY mission*. The preliminary set up of the Wärtsilä 46TS-DF engine with NextDF function will likely be onboard the cruise ship, MSC World Asia, being constructed by Chantiers de l’Atlantique (CdA) in Saint-Nazaire, France for the Geneva-based cruise operator MSC Cruises.
Nysjö continues: “Homeowners and operators more and more want engines with greater effectivity, decrease emissions, elevated gasoline flexibility and decrease working prices. The Wärtsilä 46TS-DF engine already meets these wants, representing a versatile, future-proof resolution that may be upgraded in response to sustainable gasoline availability. By making our NextDF expertise out there for the Wärtsilä 46TS-DF engine we allow operators to go even additional in reducing GHG emissions and dangerous native pollution.”
The Wärtsilä 46TS-DF engine is the third Wärtsilä dual-fuel engine to be made out there with NextDF expertise. In 2023 and 2024, Wärtsilä launched the brand new expertise for its Wärtsilä 31DF and Wärtsilä 25DF engines.
