Description:
- Small ferries typically feature two propellers, one in bow and one in stern. Propellers can rotate by 360° to
give requested maneuverability to the ferry. - Each propeller is driven by two engines located in two separate engine rooms.
- In each engine room is also one auxiliary gen-set.
- Propulsion engines are controlled by InteliDrive DCU Marine, in PROP configuration, via J1939 bus. Redundant J1587 bus is used in case of J1939 failure.
- Requested speed is defined by 4–20 mA signal from the bridge.
- InteliDrive controllers make propulsion load-sharing to keep engines evenly loaded.
- Engines of auxiliary gen-sets are controlled by InteliDrive DCU Marine in AUX configuration.
- InteliDrive controllers communicate to a ship’s control and visualization system via Modbus RTU/TCP converter and Ethernet bus.
- Optimal configurable structure of InteliDrive’s Modbus message together with high communication speed of Ethernet bus gives immediate information on engine speed and torque required on the bridge of a quickly maneuvering ship.
