19 CONCLUSIONS Speed and ice condition are two main parameters which affect the fuel consumption. In tough ice the resistance is increased and the speed is reduced, the required power is higher than in open water. If there is no ice the ship will run faster and also consume more fuel. Higher fuel consumption might occur at high speed and low ice conditions as well as in tough ice at lower speed. Calculation of Fuel Consumption and Exhaust Emissions from Ship in Ice Conditions 19
