What Is the BMS-2000II & EMS-200II System?
The BMS-2000II is a sophisticated propulsion automation platform that allows remote operation of the ship's main engine from the navigation bridge.
The system performs multiple functions:
- Engine start and stop control
- Ahead and astern maneuvering
- Speed regulation
- Fuel control
- Safety shutdown monitoring
- Slowdown request handling
- Alarm management
- Bridge and engine room control transfer
It acts as the communication link between the ship's bridge and the propulsion machinery.

Working Principle
The BMS-2000II continuously exchanges signals between bridge controls, engine control systems, and propulsion machinery.
Operating Sequence
- Bridge operator selects maneuvering command.
- Command is transmitted to EMS-200II control system.
- Engine parameters are verified.
- Safety interlocks are checked.
- Engine receives speed and direction commands.
- System monitors engine response.
- Alarms and protection systems remain active throughout operation.
This closed-loop control ensures safe propulsion management.
