OVERALL MARINE MACHINERY DESIGN FOR TOTAL ECONOMY

The fuel crises of recent years have created the need for marine propulsion engines burning the least-expensive low-grade fuels. Such engines have been developed. However, they require a considerable amount of auxiliary power to drive various pumps circulating the large quantities of oil, coolant, and sea water with which the main engine must be supplied. This auxiliary power is usually produced by Diesel-generators which use more expensive fuels and which are also less fuel-efficient than the main engine. The effect is to increase the overall fuel consumption by about 7%. Moreover, the auxiliaries are associated with a multitude of electric motors and electronic control devices which in aggregate are less reliable than the main engine. It is proposed that the electric sea load required for main engine services should be reduced by transferring the engine service pumps from electric to mechanical drive when the engine is at full speed. The total system is described in detail within the economy package.
