Crankcase explosion for two-stroke marine diesel engine by using fault tree analysis method in fuzzy environment
Ünver, Bedir; Gürgen, Samet; Şahin, Bekir; Altın, İsmail (Elsevier, 2019)The purpose of this study is to investigate crankcase explosion in two-stroke marine diesel engine systematically by using fault tree analysis method in fuzzy environment for system reliability and shipping sustainability. ... -
Experimental investigation on cyclic variability, engine performance, and exhaust emissions in a diesel engine using alcohol-diesel fuel blends
Gürgen, Samet; Ünver, Bedir; Altın, İsmail (Serbian Society of Heat Transfer Engineers, 2017)This paper investigates the impacts of using n-butanol-diesel fuel and ethanol-diesel fuel blends on engine performance, exhaust emission, and cycle-by-cycle variation in a Diesel engine. The engine was operated at two ... -
Forecasting the Baltic Dry Index by using an artificial neural network approach
Şahin, Bekir; Gürgen, Samet; Ünver, Bedir; Altın, İsmail (TÜBİTAK Scientific & Technical Research Council Turkey, 2018)The Baltic Dry Index (BDI) is a robust indicator in the shipping sector in terms of global economic activities, future world trade, transport capacity, freight rates, ship demand, ship orders, etc. It is hard to forecast ... -
Prediction of cyclic variability in a diesel engine fueled with n-butanol and diesel fuel blends using artificial neural network
Gürgen, Samet; Ünver, Bedir; Altın, İsmail (Elsevier, 2018)In this study, the cyclic variability of a diesel engine using diesel fuel and butanol diesel fuel blends is modeled using an artificial neural network (ANN) method. The engine was operated with ten different engine speeds ... -
Risk ranking of maintenance activities in a two-stroke marine diesel engine via fuzzy AHP method
Ünver, Bedir; Altın, İsmail; Gürgen, Samet (Elsevier, 2021)Maintenance activities in ship machineries are of vital importance due to economical and operational requirements. Most of ships in commercial activities have two-stroke marine diesel engines (MDEs) in the propulsion ...
