Over the past 15 years, Viking Line has succeeded in reducing carbon dioxide emissions from its vessels by nearly a third. Environmental investments have been made in the Baltic Sea’s most climate-smart vessels and in the technology on board every vessel. Viking Glory and Viking Grace are already equipped to start running on green fuels, which will enable truly carbon-neutral service in the future.

Thursday, August 25, is Baltic Sea Day. To celebrate the occasion, Viking Line will donate 30,000 euros from the sale of plastic carrier bags in its tax-free shops to the John Nurminen Foundation. At the same time, the autumn’s sustainability theme on Viking Line’s vessels, in the terminals and in the company’s communication channels will be launched with the aim of involving passengers in this important work for the good of the Baltic Sea.

“The Baltic Sea is really important to us Finns in many ways. The Baltic Sea has always been a gateway to the world and to international markets, but also an important provider of experiences and recreation. Our feeling for this place gives us an identity that brings together the countries around the Baltic and their residents, and this is something that the John Nurminen Foundation safeguards. The Baltic Sea and its condition are of great relevance to Viking Line each and every day. With Viking Line’s support, we can take effective, result-oriented measures to ensure that the Baltic Sea maintains its biodiversity and well-being for future generations as well. We believe that proximity to the sea and its importance to people help raise people’s awareness of its condition,” says Annamari Arrakoski-Engardt, Managing Director of the John Nurminen Foundation.

Carbon dioxide emissions from Viking Line’s vessels have decreased 30 per cent per nautical mile since 2008. One factor behind this significant reduction is the company’s active environmental work consisting of a wide variety of measures. The measures that have had the greatest impact are the 450 million euros invested in the two most climate-smart vessels on the Baltic Sea: Viking Grace, which made its maiden voyage in 2013, and Viking Glory, which was placed in service in March.

“We have mainly achieved emission reductions through innovative technological solutions that are not very visible to passengers. The technology is developing at a rapid pace, and many of these innovations originated in Finland. When Viking Grace, which is powered by natural liquefied gas, was placed in service, emissions of nitrogen and particulate matter decreased 85 per cent and greenhouse gas emissions decreased 15 per cent compared to a vessel that runs on oil. Now ten years later, Glory in turn produces ten per cent fewer emissions than Grace. Meanwhile, emissions from our older vessels have also decreased, since we update the technology on our vessels throughout their life cycle,” says Dani Lindberg, Sustainability Manager at Viking Line.

The goal of the International Maritime Organization (IMO) is to reduce carbon dioxide emissions from maritime transport by 40 per cent from 2008 levels by 2030.

“We are Finland’s largest maritime transport employer, and our shipping company has the most vessels under a Finnish flag. We also want to be a pioneer in developing and implementing new, environmentally-friendly innovations. For example, Grace and Glory are already equipped to start using biogas or synthetic fuels produced from renewable energy when they become available in the future. That is the next big step towards carbon-neutral maritime traffic,” says Dani Lindberg.

Viking Line’s environmental journey began in earnest in the 1980s, when the company started using divers to scrub the bottoms of its vessels instead of using toxic paint. Recycling on board also began as far back as four decades ago. Since then, the vessels have made the transition to increasingly low-emission fuels and to energy recycling. In port, the vessels have started to be supplied with green land-based power. Fuel efficiency is now taken into account when timetables and routes are planned.

“On board Viking Grace alone, the intelligent, need-based ventilation system saves the same amount of energy that all of our offices and warehouses use in one year. And that is just the case of a single technological innovation on one vessel. It is also crucial how the vessel is used and operated. The responsibility for this lies with our skilled professional staff, for whom environmental issues have top priority along with safety and security.”

Viking Line’s environmental journey

1980s

• Viking Line stops using toxic paint on the bottom of its vessels, and divers start brushing the vessel bottoms to clean them.

• The vessels start recycling waste.

• The first-land based power supply is placed in service in Stockholm. Today, land-based power is also supplied in Helsinki, Mariehamn and Tallinn.

1990s

• Sulphur dioxide emissions are reduced thanks to the switch to low-sulphur fuel.

• Wastewater on the vessels starts to be treated on shore.

• Cooling available from the bottom of the sea starts to be used to cool ventilation air on the vessels, and energy from flue gases starts to be used to heat ventilation air.

2000s

• Viking Line is the first shipping company in the world to use the humid air motor method to reduce nitrogen dioxide emissions. The method involves reducing the combustion temperature of the vessel’s main engines by cooling them with sea water.

• Viking Cinderella’s carbon dioxide emissions are reduced when the vessel is equipped with catalytic converters.

• Viking XPRS is the first vessel to start recycling biowaste.

2010s

• The new Viking Grace runs on entirely sulphur-free natural gas. The climate-smart vessel reduces emissions of sulphur and particulate matter by 85% and greenhouse gas emissions by 15% compared to a vessel that runs on oil.

• A rotor sail is tested on Viking Grace, making it the first hybrid vessel to use both LNG and wind power. An energy recovery system that converts waste heat into electricity is installed on all the vessels.

2020s

• ELOGRIDs are installed on Viking Gabriella and Viking XPRS, which reduce fuel consumption and carbon dioxide emissions.

• Viking Glory is one of the first vessels in the world to have engines that run on liquefied natural gas (LNG). They enable the optimization of fuel consumption and do not produce any sulphur emissions.

• Thanks to Viking Glory’s Azipod steerable propeller system, it is easier to turn the vessel around in port, and manoeuvring the vessel uses less time and fuel. The design of the vessel hull reduces the formation of waves and fuel consumption.

• Viking Glory is also a pioneer in utilizing waste cooling from LNG. The energy recovery system produces a full 40 per cent of the electricity needed for the vessel’s passenger functions.

• On Viking Glory, lights are turned off in empty cabins, while air conditioning and heating are turned down automatically.

What happens next?

• The vessels’ energy consumption and emissions will continue to be reduced. Viking Line will continue to follow advances in new fossil fuels and energy storage. The company is taking part in various trials and projects, which include testing new cleantech innovations and clean fuels.

• Viking Grace and Viking Glory will run on biogas or synthetic fuels produced from renewable energy when they become available in the future.
