World’s Largest Catamaran To Have A Propulsion System From Wärtsilä

51

The technology group Wärtsilä will supply the engines, water jets, and fuel storage and supply system for a new high speed catamaran ferry, says a press release on their website.

Ferry operator

The vessel is being built at the Incat yard in Tasmania, Australia on behalf of Argentinian ferry operator, Buquebus.

Having an overall length of 130 metres, a width of 32 metres and the capacity to carry 2,100 passengers and 226 cars, it will be the largest aluminium catamaran ever built by Incat. The order with Wärtsilä was placed in July 2022.

Dual-fuel engine technology

The vessel will operate between Argentina and Uruguay with Wärtsilä’s 31 dual-fuel engine technology using primarily LNG fuel produced at Buquebus own LNG plant.

Main engine gearboxes

The vessel will also incorporate shaft e-motors powered via the main engine gearboxes taking further advantage of Wärtsilä’s LNG technology. With LNG, the minimised emissions of CO2, nitrous oxides (NOx), sulphur oxides (SOx) and particulate matter will make the ferry Tier III compliant and able to operate in emission control areas (ECAs).

Largest and greenest vessel

“We have selected Wärtsilä waterjets many times in the past, and have always been extremely satisfied with their performance,” says Tim Burnell, Incat’s CEO.

“This though is the first time we will include Wärtsilä engines, and we are excited about the potential they provide. This will be the world’s largest and greenest vessel of its type, and we are very happy to be working with Wärtsilä to make the project a huge success.”

Advanced Propulsion Control System

“This is indeed an exciting project. Our latest WXJ generation axial flow waterjets reduce the installation footprint on average by approximately 25 percent, compared to non-axial flow jet designs. They also give a higher power-to-weight ratio, and come with an advanced Propulsion Control System. Combining this with our highly efficient, fuel flexible engines, means that it is a truly future-proof investment,” adds Mikko Mannerkorpi, General Manager, Sales, Wärtsilä Marine Power.
