Cost Efficiency and Emission Analysis of a Bulk Carrier Cranes Operation

Abstract

This study carries out economic analyzes of the cranes belonging to the M/V Ince Inebolu. Analyzes were repeated for variable fuels considering ECA (Emission Control Areas), and variable fuel prices were included into analyzes given the fluctuating fuel prices As a result of these analyzes, the amount of fuel consumed has been determined by calculating the power of the diesel generator from the operation of the crane In addition, this study calculated how much NOx, SO2, CO2, PM and HC emissions this fuel generates. Since a crane is operated at 25% of the generator load, in a year, a company, with 10 ships with similar characteristics to the vessel where the work was done, has released about 30-35 tons of SO2, 38-42 tons of NOx 1980-2090 tons of CO2, 2.8-3 tons of PM and 4.2-4.5 tons of HC emissions to the atmosphere The results demonstrate that running the crane with the diesel generator at 25% load causes between 60.000USD - 70.000USD annual operating cost for IFO 380 and IFO 180 fuels, and between 100.000USD -110.000USD annual operating cost for MGO. As a resuk this study calculates the cost of crane usage through the economic analysis of cargo loading and unloading operations of the ship by cranes, and thereby, enables a comparison with loader usage.
