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

Abstract

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. CO₂ 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.

Trol Gemilerinde Ana Makine Yakıt Tüketiminin Optimizasyonu ve CO2 Emisyonlarının Azaltılması

Abstract

Trol gemilerinde yakıt tüketiminin tespiti ve optimizasyonu üzerine yapılan bu çalışmada Lamas-1 araştırma gemisine anlık ve toplam yakıt tüketimi, hız, konum ve makine devrini gösteren ve kaydedebilen bir sistem kurulmuştur. Sistem aracılığıyla seyir ve trol operasyonu için ideal devir değerleri sırasıyla 1000 rpm ve 1400 rpm olarak belirlenmiştir. Seyir denemeleri sonucunda elde edilen değerler, yaklaşık 1 knot hız artışı için yakıt tüketiminin %100 arttığını göstermiştir. Trol operasyonunda ise elde edilen ideal devirin %28’e varan yakıt tasarrufu sağladığı bulunmuştur. Trol operasyonu ve seyir için elde edilen yakıt tüketimleri üzerinden CO₂ emisyonları hesaplanmıştır. Optimize olarak tespit edilen devir değerlerinin CO₂ emisyonları hem seyir hem trol operasyonu için diğer verilerle karşılaştırılmış ve sırasıyla %88 ve %43 emisyon azalması elde edilmiştir.
