A revolutionary series of nine LNG-powered, 22,000 TEU container vessels ordered by French carrier CMA CGM from China State Shipbuilding Corporation will feature new technology from Wärtsilä.
Wärtsilä has recently developed and received orders for LNG-fuelled auxiliary gensets for a new series of nine LNG-powered, 22,000 TEU container vessels. Each of the ships, due for delivery in 2020, will have six W34DF gensets installed on board and the contract is described by Wärtsilä as being a significant step for the container shipping industry.
Wärtsilä product director Patrik Wägar said: “By running on LNG compared with diesel you can reduce NOx emissions by 85% and CO2 by 25%, significantly reducing the environmental footprint of the operation. The global sulphur cap in 2020 will clearly change things and will lead to a shift to LNG as fuel, but hybrid solutions are also in the spotlight. For container vessels the W34DF option will create added value with the ability to add gensets as a back-up for hotel loads in combination with single main engines, to reduce both energy consumption and CO2 emissions.”
The W34DF engine, based on the well-proven Wärtsilä 32 engine type developed in the 1990s, has already been specified for LNG carriers, offshore support vessels and shuttle tanker newbuildings. This is, however, the first time the technology has been specified within a new container ship project.
