Australian ferry firm Ro-Pax has selected Wärtsilä as its choice of engine and fuel gas supply systems for its two new vessels.

Renowned Australian ferry fleet owner and operator TT-Line Company placed the order with Wärtsilä in June 2021. The ships are being built in Finland at the Rauma Marine Constructions (RMC) yard.

The new 212-metre-long liquefied natural gas (LNG) powered ferries will add to TT-Line’s current fleet of two vessels, Spirit of Tasmania I and Spirit of Tasmania II, both of which use Wärtsilä engines and travel between Melbourne, Victoria and Devonport, Tasmania.

Speaking about the development, Bernard Dwyer, Chief Executive Officer, TT-Line, said, “Since 2002 when the current vessels were inducted into our fleet, the Wärtsilä engines have delivered both performance and reliability backed by strong serbice and technical support.”

“Keeping in mind the IMO’s stringest emission targets for the future, TT Line has opted for LNG fuelled ferries. Wärtsilä’s depth of experience and broad portfolio of LNG-fuel solutions for marine applications were prime considerations for us.”

Each ship will be installed with four Wärtsilä 46DF dual-fuel main engines, three Wärtsilä 20DF dual-fuel auxiliary engines, and two Wärtsilä LNGPac fuel storage, supply, and control systems.

Jyrki Heinimaa, President & CEO, Rauma Marine Constructions, also commented on the choice, saying, “Our goal is to be a pioneer in environmentally sustainable technology in shipbuilding, and we want to provide vessels to our customers accordingly. The LNG-powered engines play an important part in building two new eco-efficient and future-proof vessels for TT-Line.”

This future-proof will allow the vessels to operate on alternative green fuels as and when the opportunity, and technology, arises. Due for the delivery of one vessel by the end of 2023 and the second one a year later, the ferries will have a capacity of 1800 passengers and around 2500 lane metres on two freight decks.
