Wärtsilä’s multi-fuel engine technology the choice for two new Australian RoPax ferries

The Wärtsilä technology group will supply the engines and fuel gas supply systems for two new Ro-Pax ferries. The ships are built at the Rauma Marine Constructions (RMC) shipyard in Finland for TT-Line Company Pty Ltd, a famous Australian ferry fleet owner and operator. The order with Wärtsilä was placed in June 2021.

TT-Line currently operates two ferries, Spirit of Tasmania I and Spirit of Tasmania II, both of which operate with Wärtsilä engines, on the route between Melbourne, Victoria and Devonport, Tasmania. This fleet is now being renewed by the construction of two new ships, 212 meters long, which will adopt the latest technologies and will be powered by LNG fuel to reduce the environmental impact.

“Since 2002, when current vessels were incorporated into our fleet, Wärtsilä engines have provided both performance and reliability backed by strong service and technical support. Bearing in mind IMO’s stringent emissions targets for the future, TT Line has opted for LNG-fueled ferries. Wärtsilä’s extensive experience and its broad portfolio of LNG-fuel solutions for marine applications have been paramount considerations for us, ”said Bernard Dwyer, CEO of TT-Line.

“We have worked closely with TT-Line for several years and are happy and proud to continue this long-standing relationship through this latest new build project. We will extend our best technical and operational support to the new TT-Lines ferries. Wärtsilä has played a major role in enabling LNG to become a viable and increasingly popular marine fuel, and its adoption by global operators continues to grow. This order clearly reflects this trend, ”says Mikko Mannerkorpi, General Sales Manager, Wärtsilä Marine Power.

“Our goal is to be a pioneer of environmentally sustainable technology in shipbuilding, and we want to deliver ships to our customers accordingly. LNG-powered engines play an important role in building two new eco-efficient and scalable vessels for TT-Line, ”said Jyrki Heinimaa, President and CEO of Rauma Marine Constructions.

The scope of supply includes, for each vessel, four Wärtsilä 46DF dual fuel main engines, three Wärtsilä 20DF dual fuel auxiliary engines and two Wärtsilä LNGPac fuel storage, supply and control systems. Engines are scalable to run on alternative green fuels as availability evolves.

The new ferries will have a capacity of 1,800 passengers and around 2,500 meters of track on two freight bridges. The delivery of the first vessel is scheduled for the end of 2023, the second a year later.
