The ETU Engine Telegraph Unit is an essential component of a ship's propulsion command and communication system. It serves as the interface between the navigation bridge and the engine control room, enabling safe and accurate transmission of engine commands during vessel operations.
Before the widespread adoption of fully integrated electronic propulsion control systems, engine telegraph systems were the primary method of transmitting engine speed and maneuvering orders. Even today, modern vessels continue to utilize Engine Telegraph Units as part of integrated propulsion control and safety systems.
The ETU Engine Telegraph Unit helps ensure clear communication between bridge officers and engineering personnel, reducing operational errors and improving vessel maneuverability during critical navigation situations such as harbor entry, departure, anchoring, and emergency maneuvers.

PRODUCT OVERVIEW
The ETU Engine Telegraph Unit is designed to electronically transmit propulsion commands between various ship control stations. The system ensures that engine orders issued from the bridge are accurately received and acknowledged by the engine control room or propulsion control station.
Modern ETU systems are typically integrated with:
- Main Engine Remote Control Systems
- Bridge Control Systems
- Engine Monitoring Systems
- Alarm and Monitoring Systems
- Integrated Automation Systems
- Propulsion Control Systems
The unit shown features multiple indication lamps and status monitoring functions, allowing operators to quickly verify command status, control location, telegraph readiness, and system health.
Common operational indications include:
- Ahead Commands
- Astern Commands
- Standby Mode
- Bridge Control Active
- Engine Control Room Active
- Emergency Control Mode
- Wrong Way Alarm
- New Command Alarm
- Internal Failure Alarm
- System Ready Status
These functions provide operators with immediate visual confirmation of propulsion command status.
