‘Viking Glory’ will be one of the most climate-smart passenger ships in the world when she is delivered in 2021, claimed operator Viking Line.
It is estimated that the ship will consume up to 10% less fuel than ‘Viking Grace , which is smaller and was hailed as the world’s most eco-friendly ship of its time when delivered.
‘Viking Glory’ will be the first ship in the world to be equipped with Wärtsilä 31DF dual fuel engines, which use the latest technology and run on completely sulfur-free LNG. As with ‘Viking Grace’, the latest ropax will also 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),” explained Project Manager, Kari Granberg, who is Viking Line’s head of new construction.
‘Viking Glory’ will also, in another first, recover the waste cold from the LNG used and recycle it for use in cold counters, cold rooms and other specialised rooms.
“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,” Granberg explained.
In addition, ‘Viking Glory’ will be equipped with a Climeon energy recycling system that harnesses and converts waste heat from the engines into electricity. This system can generate up to 40% of the electricity required for the passenger functions.
Moreover, a dynamic air conditioning and lighting system will be installed on board, which will have a direct effect on energy consumption. This system will be controlled by the booking system: if a cabin remains empty at departure, it will be set in a power-saving mode, thereby minimising air-conditioning and heating for that particular cabin.
This will also marks the first time a passenger ship of this type will be fitted with ABB’s Azipod propulsion unit, as a means of saving time and energy in terms of ship manoeuvring: this system allows faster turns in ports and a hull design with about 8% less water resistance than with a traditional 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 who is in charge of developing the new ship’s concept.
