Thanks to its advanced solutions and technical innovations, Viking Line says its newbuild Viking Glory will be one of the most climate-smart passenger ships in the world
It is estimated 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.
Viking Glory will launch into service in 2021 as the first ship in the world to be equipped with Wärtsilä 31DF dual-fuel engines, which utilise the latest technology and run on LNG. As with Viking Grace, Viking Glory will also have the ability to run on biogas, once it becomes a viable fuel alternative in the future.
“Viking Glory will have six 31DF engines for efficient fuel optimisation. 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 in charge of the new construction at Viking Line.
Viking Glory will also, as the first in the world, recover the waste cold from using LNG and recycle it for use in cold counters, cold rooms and other special rooms.
“Today, recovery of waste heat is already common, but to recycle waste cold for 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,” Mr Granberg continued.
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 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, minimising air-conditioning and heating for that particular cabin.
This also marks the first time a passenger ship of this kind utilises the Azipod propulsion unit manufactured by ABB as a means of saving time and energy in terms of ship manoeuvring: the system facilitates faster turns in the ports and a hull design with approximately 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 Viking Line head of development Gustaf Eklund.
