WAYS TO REDUCE SLOW STEAMING FUEL CONSUMPTION OF STEAM TURBINE MACHINERY THROUGH TECHNICAL MODIFICATIONS

Over the past 5-6 years slow steaming has been a rather common mode of operation for a large number of ships, particularly ships with high propulsion power. The underlying cause of this has been a very large rise in bunker fuel prices since 1973-74, while charter rates at the same time in general have stayed quite low. A study has been performed of select configurations of steam turbine machinery to determine what fuel savings can be obtained, particularly at part load, through changes in method of operation or through technical modifications that for the most part are relatively moderate. Results are presented in the form of percentage fuel savings and in terms of cost savings. The savings may range from 0.5% to 10%. With fuel oil prices at its present high level, a fuel reduction of only 0.5% may represent a large annual cost saving well worth making an effort to achieve.
