The present invention relates to a system and a method for control and reduction of the RPM of at least one main engine of a vessel, which main engine drives at least one first propeller for propulsion, which first propeller is pitch-regulated, which second thruster propeller is pitch-regulated. It is the object of the invention to reduce the RPM of one ore more main engines of a vessel and by increasing the pitch of the propellers to maintain constant propulsion, and by reducing the RPM of the main engines to re-duce the fuel consumption and in this way reduce pollution. The object can be fulfilled by a system analysing the RPM and pitch of the first main shaft propeller, which system analyses the RPM and the pitch of the second thruster propeller, which system based on said analyses performs downward regulation of the RPM of the main engine.
A system for controlling and optimizing the RPM of at least one main engine of a vessel, which main engine is configured to drive at least one pitch regulated main propeller for propulsion to drive at least one main generator, and to drive at least one thruster motor, which thruster motor is configured to drive at least one thruster propeller that is pitch-regulated, wherein the system is configured to perform an analysis of the RPM and pitch of the main shaft propeller, the RPM and the pitch of the thruster propeller, which systems is configured to operate based on said analysis and which system is configured to receive a plurality of input from other control systems in the vessel, and to performs regulation of
