VIKING LINE REVEALS ENVIRONMENTAL CREDENTIALS OF NEW RO-PAX

Thursday, October 31, 2019 

Ferry operator Viking Line of Finland says that its latest ro-pax, ‘Viking Glory’, currently in build at the Xiamen shipyard in China, will be one of the most climate-smart passenger ships when it enters service in 2021.

It is estimated that the ship will consume up to 10% less fuel than the smaller Viking Grace, thanks in part to its LNG-fuelled Wärtsilä 31DF engines. As with Viking Grace, Viking Glory will have the ability to run on biogas, once it becomes a viable fuel alternative.

Viking Glory will have six 31DF engines for efficient optimisation of fuel consumption. These engines have the lowest fuel consumption, but at the same time, the highest cylinder output in their segment (550 kW/cylinder),” said Project Manager Kari Granberg.

Another first is the use of recovery technology to use waste cold from the LNG fuel system and recycle it for use in cold counters, cold rooms and other cool areas.

“Today, recovery of waste heat is already common, but to recycle waste cold for the purposes of refrigeration appliances and cold rooms is an innovative and highly climate-smart solution. Viking Line has carried out development work in collaboration with Wärtsilä, Projektia and Deltamarin,” said Granberg.

Additionally, Viking Glory will be equipped with a Climeon energy recycling system that harnesses and converts waste heat from the engines into electricity. The system can generate up to 40% of the electricity required for the passenger functions. A dynamic air conditioning and lighting system will be installed onboard, which will be linked to the booking system, so that empty cabins will be set in a power-saving mode, thereby minimising air-conditioning and heating for that particular area.

Viking Glory will be the first passenger ship of its type to use ABB Azipod propulsion units, facilitating faster turns in ports and enabling a hull design with about 8% less resistance than with a conventional propeller system.

“Viking Line endeavours to be a forerunner of responsible navigation, and this goal is reflected in the design and construction of our new ships. Those technological innovations we are now testing and developing jointly with our Nordic partners constitute the foundation for the novel cruise experiences through the archipelago,” said Gustaf Eklund, Head of Development at Viking Line.
