In the world economy and the shipping industry, container, bulk carriers and oil tanker vessels areundergoing a bigger difficulty because of the imbalance on supply and demand with the view that ship'sloading capacity is exceeded. For this reason, shipping companies are trying to reduce the operating costthrough slow steaming. Thus, under this condition of continuous recession in shipping industry, saving onfuel consumption is the main issue. In this study, tests were conducted to find out the method ofreducing fuel oil consumption by economically operating the ships, taking into account the main enginepower and speed. The subject vessel's fuel consumption compared to the output is lower near the rangeof 138~157RPM. The engine speed showed significant increment to 144RPM and fuel consumptionincreased rapidly compared to the engine speed at 15knots and above. During sea trial test, the subjectvessel's specific fuel rate(SFR) was 134.25[g/BHPh] while the calculated value after 10 years ofoperation is 137.1[g/BHPh] at speed range of 148~150RPM which is 70% of the load and this indicatesan increase of approximately 2.1%.
Abstract
In the world economy and the shipping industry, container, bulk carriers and oil tanker vessels areundergoing a bigger difficulty because of the imbalance on supply and demand with the view that ship'sloading capacity is exceeded.

Thus, under this condition of continuous recession in shipping industry, saving onfuel consumption is the main issue. In this study, tests were conducted to find out the method ofreducing fuel oil consumption by economically operating the ships, taking into account the main enginepower and speed. The subject vessel's fuel consumption compared to the output is lower near the rangeof 138~157RPM. The engine speed showed significant increment to 144RPM and fuel consumptionincreased rapidly compared to the engine speed at 15knots and above.
