Wärtsilä is to supply the engines, waterjets, and fuel storage and supply system for a new high speed catamaran ferry.

The ferry is being built at the Incat shipyard in Tasmania, Australia for Argentinian ferry operator, Buquebus.

She will have an overall length of 130 m, a beam of 32 m and a capacity to carry 2,100 pax and 226 cars. She will be the largest aluminium catamaran yet built by Incat and will operate between Argentina and Uruguay, across the River Plate.

With Wärtsilä’s 31 dual-fuel engine technology fitted, she will primarily use LNG fuel produced at Buquebus own LNG plant. The vessel will also incorporate shaft e-motors powered via the main engine gearboxes.

“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.”

“This is indeed an exciting project. Our latest WXJ generation axial flow waterjets reduce the installation footprint on average by approximately 25%, 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,” Mikko Mannerkorpi, General Manager, Sales, Wärtsilä Marine Power, added.

Wärtsilä will supply four 31DF dual-fuel engines, four WXJ1500SR waterjets, and two LNGPac fuel storage, supply and propulsion control systems. The equipment will be delivered to the yard commencing in mid-2023.

The company claimed that the 31DF is the most powerful engine in its class. It has a power output ranging from 4.6 to 9.6 MW at 720 and 750 rev/min. The higher output per cylinder provides a compact footprint and a cost-efficient installation. The diesel version of the Wärtsilä 31 has been recognised by Guinness World Records as the world’s most efficient 4-stroke diesel engine.
