No hazardous bottom paint

Instead of using environmentally hazardous tin-based paints on the bottoms of vessels, their hulls are brushed by divers several times each year.

The diving company that Viking Line works with uses a patented, environmentally sound brushing method that it developed inhouse. This method involves collecting all growths loosened from the bottoms of vessels during brushing into a separate container, which is then brought ashore for further treatment. The waste is used in part to make biogas.
