OUR PARTNER

Viking Line is a ferry operator in the Baltic region and has seven vessels going between Finland, Sweden and Estonia. 6.6 million passengers travel with Viking Line every year. In 2013 Viking Grace was built and she was the first ship that was built with LNG as fuel. As a shipping company on the Åland Islands, between Sweden and Finland, the company places great importance upon protecting the sea environment that they are surrounded by. They strive to be the forerunner in utilizing new solutions that reduce environmental impact.

THE OPPORTUNITY

After personnel, energy is the second biggest cost for Viking Line and therefore energy efficiency is crucial. Viking Line is continuously working to find solutions that are both economically and environmentally profitable. A ship's engine generates large amounts of waste heat found in the engine cooling water and exhaust gas, which can be turned into valuable electricity (fuel savings) with a Climeon Heat Power system.

OUR SOLUTION

The pilot project for Climeon was designed for an easy retrofit application, so no major construction was needed on the boat and the installation could take place during normal operation. Climeon's Heat Power system utilizes waste heat from the ferry's engines and exhaust gases. On average 700,000 kWh clean and emission-free electricity is produced annually. The electricity is primarily used on the cabin decks, for example for the lighting.

Head Of New Build Projects, Viking Line

“We have been looking at different organic rankine cycles and the efficiencies of those equipment’s have been very low. When we discovered the Climeon Heat Power system, we found that it was a suitable solution for us. With the Climeon Heat Power system we can save money and at the same time clearly decrease our carbon footprint. We have now decided to include the Climeon Heat Power system as we develop new vessels and are evaluating the possibility of rebuilding our existing vessels so that the technology can be used throughout our existing fleet”
