In order to achieve the local automatic twin-engine parallel operation of the main engine of a ship, an innovative solution is adopted to add a local “remote control station”- local twin-engine parallel control box- into the standard architecture of the imported main engine remote control system (RCS), and to move the core control unit of the system from the centralized control platform to the control box, aiming at the difficulty of modifying the standardized equipment of imported propulsion monitoring device. The implementation of the local automatic twin-engine parallel operation is described in views of the system architecture modification, control box function design, human-machine interface (HMI) design and ship application. This scheme also ensures that the local engine room still has partial automatic control and back-up control function of the main engine remote control system in the event of the failure of other remote control stations.
