fi sh vessels go electric









                     The Norwegian aquaculture and fi shing industry has joined the green
                     shipping wave with a number of pioneering electric fl eet initiatives.

                     concept is based on a 70-meter long vessel
                     that can be converted to fi t either a hybrid LNG

                     would cut down on NOx, SOx and CO2
                     emissions. CO2 alone would be reduced by
                     240 tons per year, the equivalent of 130 cars.
