The world’s largest aluminum catamaran powered by LNG is being built

Finnish technology group Wärtsilä has been contracted to supply engines, waterjets, and fuel storage and supply system for a new high speed catamaran ferry powered by LNG.

September 16, 2022. Finnish technology group Wärtsilä has been contracted to supply engines, waterjets, and fuel storage and supply system for a new high speed catamaran ferry powered by liquefied natural gas (LNG).

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

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).

“This 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,” Tim Burnell, Incat’s CEO, commented.

The equipment will be delivered to the yard commencing in mid-2023.
