In this article there are covered several operational methods for improving energy efficiency of a ship using using the Fluid Flow Modeling (CFD) program, Ansy s Fluent. The maritime transport sector is under considerable pressure to increase energy efficiency. While C02 emissions are decreasing in many other sectors, maritime transport emissions are expected to be increased in the future. Shipping Industry currently accounts for about 3% of global CO2 emissions. As a result of increased transportation, and in combination with difficulties in implementing effective energy efficiency measures, its share is expected to grow. Fuel efficiency is linked to air emissions, measures and policies that successfully improve energy efficiency. Various researches have been carried out in the field of alternative power sources and into technical, operational and stmctural energy saving measures for shipping industry. In order to reduce fuel consumption and to increase energy efficiency we should take care about the position of the bow thruster, the location of the fins, the bilge keels, the form of the central skeg, the sea chest openings dimensions, the seemingly of the propellers, the rudders form, the hull openings position, the zinc anodes & lifting eyes position, the hull surface condition. The evaluated savings in resistance correspond to savings of the fuel that is consumed by the propulsion. Speed range ofl8knto21kn is considered for the improvement percentages.
