4、rom the Kyoto treaty. 40 percent of NOx emissions derive from the shipping and fishing industries along the coast and from offshore shipping.By using gas fuel will cut emissions of NOx.M/S Viking EnergyFollowing three years of development, the worlds first gas-powered cargo ship is now in operation.

5、 The offshore supply ship, named Viking Energy is powered by liquefied natural gas (LNG) with dual-fuel engines.Reduced emissions: By operating on gas, the emissions of NOx are reduced by approximately 90 percent and of CO2 by approximately 30 percent compared with operating on diesel. For the given

6、 operational profile, the emissions of NOx is reduced by 60 kg and of CO2 by 1175 kg for each ton of LNG consumed. The yearly consumption of LNG is estimated at 3000 3500 tons for each ship.Administrative and Operational SupportSystemsAdministrative and Operational SupportSystemsSalesLogisticsEconom
