CONSTRUCTION of the world’s largest aluminium ship is progressing in Tasmania with technology group Wärtsilä to supply a population package.
The package includes engines, waterjets and a fuel storage and supply system for the high-speed catamaran.
Shipbuilder Incat secured the contract to build the 130-metre-long vessel in 2019, for South American ferry operator Buquebus.
The vessel will operate between Argentina and Uruguay with 31 dual-fuel engine technology, supplied by Wärtsilä, and primarily using LNG fuel.
Wärtsilä said the vessel will also incorporate shaft e-motors powered via the main engine gearboxes, which also incorporates LNG technology.
Incat CEO Tim Burnell said the shipbuilder had always been satisfied with the performance of waterjets supplied by Wärtsilä.
“This though is the first time we will include Wärtsilä engines, and we are excited about the potential they provide,” he said.
“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.”
Mikko Mannerkorpi, Wärtsilä Marine Power general manager sales, said the axial flow waterjets being supplied reduce the installation footprint by around 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,” Mr Mannerkorpi said.
“Combining this with our highly efficient, fuel flexible engines, means that it is a truly future-proof investment.”
The full propulsion package includes four Wärtsilä 31DF dual-fuel engines; four Wärtsilä WXJ1500SR waterjets; and two Wärtsilä LNGPac fuel storage, supply and propulsion control systems.
The equipment will be delivered to the yard commencing in mid-2023.
