Optimization of Main Engine Fuel Consumption and Reduction of CO2 Emission in Trawl Fisheries

In this study on the determination and optimization of fuel consumption in trawlers, a system has been established which could display and record of instant and total fuel consumption, speed, position and engine rpm in Lamas-1 research vessel. The ideal rpm values for cruising and trawling operation have been determined as 1000 rpm and 1400 rpm through the system respectively. The values obtained from cruise trials have been proved that speed increase of approximately 1 knot have been a hundred percent (100%) increase in the fuel consumption. Furthermore, obtained ideal rpm value for trawl operation has been achieved up to 28% fuel savings. CO 2 emissions have been calculated from obtained cruising and trawling fuel consumptions. CO2 emissions of optimized rpm values have been compared for both cruising and trawling operation values, and the reduction of 88% and 43% attained respectively
