MEDIUM-SPEED DIESEL-ENGINE PROPULSION FOR OPTIMAL ECONOMY IN SHIP OPERATION

This article presents an appraisal of the benefits of medium-speed Diesel propulsion through direct economic comparison with other propulsion systems suitable for a Ro-Ro vessel of 20,000 dwt and 19 knot service speed. The unit evaluated in this comparison is a Stork Werkspoor Diesel type TM. Four main areas of comparison are capital outlay, fuel costs, maintenance costs and lubricating oil costs. A table showing detailed comparisons with gas turbine, steam turbine and slow-speed Diesel systems is given. The medium-speed system is seen to offer cost advantages in 80% of operating costs and is at a disadvantage in an area embracing only 0-5--2.0% of costs. In addition there are technical advantages present over a slow-speed Diesel propulsion system. Order from BSRA as No. 49,648.
