Viking Line to launch alternative-fuel passenger ship

M/S Viking Glory will be one of the most eco-efficient passenger ships in the world when it goes into service in 2021.

Powered by six Wärtsilä 31DF dual-fuel engines, it will run on sulfur-free liquefied natural gas, while also having the capability to run on biogas, minimizing its carbon footprint. Viking Glory will also recover waste cold from the use of LNG and recycle it for cold areas around the ship, such as cold counters and storage rooms.

“Viking Glory will have six 31DF engines for efficient optimization of fuel consumption. These engines have the lowest fuel consumption, but at the same time, the highest cylinder output in their segment (550kW/cylinder),” explained project manager Kari Granberg from Viking Line.

Further efficiencies will be gained with the use of a Climeon energy recycling system that scavenges waste heat from the engines and converts it to electricity, sufficient to provide up to 40% of the power required for passenger use. The air-conditioning and lighting systems will also be controlled by the booking system, so that cabins that are empty on departure are set to a power-saving mode for the duration of the voyage. The Viking Glory will also be the first passenger ship of its kind to use the ABB Azipod propulsion unit, which enables faster turning at port and offers up to 8% less water resistance than conventional designs.
