Viking Glory SchematicViking Line’s LNG-fuelled Viking Glory, planned for launching in 2021, will be one of the world’s most climate-conscious passenger ships when completed. It is estimated to use up to 10% less fuel than the smaller Viking Grace, once awarded the world’s most environmentally friendly.

Viking Glory is the first ship in the world to be equipped with Wärtsilä’s 31DF multi-fuel engines using state-of-the-art technology and completely sulfur-free liquid natural gas (LNG). Like Viking Grace, Viking Glory can also use biogas as a fuel when such an option becomes available in the future.

“Six 31DF engines will be installed to optimize fuel efficiency. These engines have the lowest fuel consumption in their segment but also the best cylinder output (550 kW / cylinder)”, says Kari Granberg, Project Manager for New Build at Viking Line.

Viking Glory will also be the first in the world to recover the wasted cold from LNG and utilize it for refrigeration and refrigeration and other specialized facilities. “Nowadays, it is already common to utilize waste heat, but utilizing waste cold to cool refrigeration equipment and other special spaces is truly innovative and climate-wise. Wärtsilä, Projektia and Deltamarin have been partners in the development of Viking Line”, Granberg continues.

Viking Glory will also be fitted with a Climeon energy recycling system that converts the waste heat from the engines into electricity. The system can generate up to 40% of the electricity required for the ship’s passenger functions. In addition, the vessel will be fitted with a dynamic ventilation and lighting system, which will have a direct impact on energy consumption. The system controlled by the reservation system works so that if a cabin is left empty when the ship leaves, it goes so-called. saving space, that is, cabin ventilation and heating is minimized.

Viking Glory is also the first passenger ship of its kind in the world to use the ABB-supplied Azipod propeller system. The system allows less time and energy to steer the ship, allowing for quicker turns in ports, and the hull can be designed so that the drag resistance is about 8% lower than with a traditional propeller.

“Viking Line is a pioneer in responsible shipping, which is reflected in the design and implementation of our new vessels. Together with our Nordic partners, we are testing and developing technical innovations that will form the basis for a new type of cruise experience in the archipelago”, says Gustaf Eklund, Head of Business Development at Viking Line, responsible for developing the new ship concept.

Viking Glory‘s technical innovations in a nutshell:

  • Wärtsilä’s multi-fuel engines make it possible to optimize fuel consumption.
  • The use of LNG (Liquefied Natural Gas) produces zero sulfur emissions and lower CO2 emissions compared to diesel.
  • The wasted cold from the use of LNG is utilized to cool the ship’s refrigeration equipment and spaces and specialty spaces .

Climeon’s energy recycling system is estimated to generate up to 40% of the electricity required for passenger consumption.

ABB’s Azipod propeller system saves time and fuel while steering the ship. Viking Glory is the first passenger ship of this type to be fitted with this propeller system.

Dynamic ventilation and lighting save energy. Some spaces have sensors that automatically turn off the lights when the space is empty. In addition, ventilation is automatically reduced when the space has not been used for a while.

The new building is part of the Finnish-Swedish EU project

The Connecting Europe Facility (CEF), which aims to promote green, vibrant, attractive and efficient maritime transport links throughout the transport chain, has a specific focus on the Motorways of the Sea (MoS). It is a pillar of maritime transport in the Trans-European Transport Network (TEN-T).

CEF has provided EU funding to Viking Line, the ports of Turku, Stockholm and Mariehamn and the City of Turku for the joint NextGen Link EU project. The purpose of the project is to enhance the maritime transport link between Turku, Mariehamn and Stockholm by means of a new LNG vessel and improvement of port infrastructure. The project is in line with the EU TEN-T guidelines as it contributes to increasing the use of more sustainable fuels and thus reducing emissions, as well as improving and improving logistics on the Turku-Stockholm route.

The Turku-Mariehamn-Stockholm route is located on the so-called Scandinavian-Mediterranean Core Network Corridor, which the EU has identified as being of particular importance for TEN-T. The EU project led by the Port of Turku will continue in 2017–2020. The maximum grant for the NextGen Link project is EUR 12.7 million.
