Finnish supplier Neste has won a bunker deal for Viking Line’s Baltic Sea passengerships.
The company said it will provide low-sulphur fuel throughout 2017.
Viking CEO Jan Hanses said: “Working to preserve the Baltic Sea and its valuable archipelagos for the future generations is important to us.
“We also appreciate that using the new marine fuel does not require us to make many changes to our ships or commit to new investments."
