ABB has installed its Power2 800-M second generation two-stage turbocharging solution on Wärtsilä 31 marine engine.
The solution is claimed to offer enhanced pressure ratio capabilities up to 12 with turbocharger efficiency above 75%, increasing engine power density.
In addition, the turbocharger is expected to deliver lower fuel costs and up to 60% lower NOx emissions.
ABB Turbocharging products senior general manager Christoph Rofka said: "Power2 800-M second generation has been developed from scratch with the two turbochargers working seamlessly together to extract a higher percentage of residual energy from the exhaust gases.
"It surpasses current industry standards in enabling increased power output, fuel savings and emission reductions.
"Our collaboration with Wärtsilä has allowed ABB’s state-of-the-art technology to be part of this first-of-a-kind engine project."
The Power2 800-M is said to be more than 20% compact compared with conventional two-stage solutions.
The Wärtsilä 31 engine will be installed on various vessels require engine propulsion in the 4.2MW to 9.8MW power range. It is offered in three variants, which are diesel, dual-fuel (DF) and spark-ignited gas (SG).
The engine adopts latest developments in fuel injection systems, engine control systems, and charge air technologies.
