Product Introduction

The NABCO M-800-II Main Engine Remote Control System is a highly reliable marine propulsion control system developed to allow safe and efficient remote operation of the ship's main engine from the navigation bridge, engine control room (ECR), and local engine-side control station.

Designed for commercial vessels operating under demanding marine conditions, the M-800-II integrates engine speed control, starting and stopping logic, telegraph command processing, safety interlocks, slowdown requests, emergency shutdown functions, and alarm monitoring into a single automation platform.

The front control panel shown in this model provides operators with real-time indication of engine control source, starting air status, bridge command, alarm conditions, slowdown requests, governor failures, control failures, speed programs, and remote control modes.

SM MARINE SERVICE™ supplies complete NABCO M-800-II systems, CPU boards, control panels, relay modules, interface boards, spare parts, repair services, calibration, commissioning support, and worldwide delivery.

What is the NABCO M-800-II Main Engine Remote Control System?

The M-800-II is the primary automation interface between the ship's bridge and the propulsion engine. Instead of manually operating the engine from the machinery space, bridge officers can issue commands such as Start, Stop, Ahead, Astern, and Speed Increase/Decrease directly from the bridge.

The controller continuously verifies that all safety conditions are satisfied before executing commands. It communicates with the governor, engine safety system, starting air system, telegraph interface, and local engine controls to ensure safe propulsion management.

---

Working Principle

The system operates through a coordinated control sequence:

1. The bridge issues an engine command.
2. The M-800-II verifies all safety interlocks.
3. The controller checks starting air pressure and engine readiness.
4. Commands are transmitted to the governor and engine actuators.
5. Engine speed is regulated automatically.
6. Continuous feedback from sensors confirms successful execution.
7. Any abnormal condition triggers alarms, slowdown requests, or shutdown protection according to the programmed safety logic.

This integrated control philosophy improves maneuverability, reduces operator workload, and enhances vessel safety during navigation.
