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.
