Method and arrangement for determining the fuel consumption of ocean-going ships

摘要

The invention relates to the field of ship propulsion and its economically advantageous management. The object of the invention is to improve the management of the main engine by determining the actual quantity of fuel consumed in every operating condition by means of sensors. For this purpose, the actual values for thermal, intrinsic and kinetic energy of the storage media and their rates of change are determined as a function of the current speed of the ship, using the known operating instrumentation. Thus the transient component of fuel consumption is determined. The analysis of the running mode thus made possible provides a continuous diagnosis of the operating state of the machinery. <IMAGE>
