Technology group Wärtsilä is set to supply a fully integrated, mechanical drive propulsion package for new 6000 dwt LNG-fuelled tankers, currently under construction.

High-Performance Engines to Power New LNG-Fueled Ships

The integrated package includes the high-performance Wärtsilä 25DF dual-fuel main engine. The company will also supply an integrated selective catalytic reduction (SCR) system, a gas valve unit (GVU), a gearbox, and a controllable pitch propeller (CPP) with seals and bearings. 

Additionally, Wärtsilä’s recently updated remote propulsion control system, featuring an enhanced ProTouch system, will improve ease of use and situational awareness for navigators and chiefs.

The ships are set for British fleet operator James Fisher Everard Ltd., part of the James Fisher group of companies. China Merchants Jinling Shipyard (Yangzhou) Dingheng Co., with design consultant FKAB Marine Design, are currently constructing the ships.

Wärtsilä state that tanker owners are exploring solutions that will support the decarbonization of their fleet and offer improved fuel economy, lower emissions, and flexibility in fueling choices.

Wärtsilä’s 25DF engine is set to support these goals, assisting users in achieving an efficient and low emissions fleet. Delivery of the Wärtsilä equipment is scheduled to take place during 2025.

Krystyna Tsochlas, Head of Maritime Transport for James Fisher, commented; “We are committed to a new, more sustainable future for our shipping operations and Wärtsilä’s expertise in delivering innovative propulsion solutions has been demonstrated throughout the vessel design development process. The dual-fuel engine will help us to serve our customer needs in a more efficient and less carbon-intensive way.

“The Wärtsilä 25DF engine offers a modular, upgradeable, and flexible design that will help to significantly reduce fuel consumption and emissions, improving the efficiency of the new tankers, and facilitating the adoption of sustainable fuels.”

Stefan Nysjö, Vice President of Power Supply, Wärtsilä Marine, added; “Fleet future proofing is of utmost importance for operators today as the industry undergoes its transformation towards optimal efficiencies and decarbonized operations. 

“The selection of our propulsion package, centered around the Wärtsilä 25DF engine, is a clear indication of how James Fisher is looking for suppliers with a strong focus on research and development, and which offer technological competence, systems integration capabilities, and in-service support for all elements of the package.”
