Rolls-Royce provides systems and equipment for control of propulsion, from the human machine interface with levers and screens on the bridge and in the control room, to control and monitoring of diesel and gas engines, propellers, waterjets, thrusters and steering gear. Complex systems such as diesel electric, gas electric and hybrid propulsion are catered for. Propulsion, thruster and steering control provides the operator with a clear picture of the propulsors and thrusters in use at the time, with magnitude and direction of thrust shown pictorially and numerically. Systems are designed to give the operator intuitive control of propulsion. Control levers and the operation panels and the underlying control architecture are optimised for the various applications of propulsion systems, but always based on the Rolls-Royce Common Control Platform and standard hardware and software modules.
