System Lay-out

The Mega-Guard Bridge Manoeuvring System is built-up with the followingindependent systems:

Remote Control System Engine Telegraph System Safety System Speed Controller

Each independent system is built-up with the same hardware and softwarecomponents in order to minimize the number of different spare parts.The independent systems communicate with each other via the Fieldbusnetwork (main/backup). The redundant Fieldbus can be delivered in Ethernetor CAN-Bus technology. Communication to other systems, such as ship's alarmand monitoring system, takes place via hard-wired signals or serial link. A seriallink interface is provided to record all events to the Voyage Data Recorder.

Advanced Control Processors equipped with I/O Modules are used in eachindependent system. Sensors and actuators are directly wired to the I/O Moduleswhich are mounted on a DIN rail.

Features

The Mega-Guard Bridge Manoeuvring System fully automates the remote control of the propulsion engine from the bridge andcontrol room. All functions of main engine remote control as required by 2 stroke engine manufacturers MAN B&W (ME andMCC Engines) and Wärtsila NSD (Flex and RTA Engines) are executed by the Mega-Guard BMS.

The reliable Operator Panels on the Bridge, the Control Room and on the Local EmergencyStand are easy to operate and to install. The remote control system receives orders from thecombined manoeuvring / telegraph lever on the Bridge or Control Room. The remote controlsystem activates starting, stopping and reversing mechanism on the engine and gives aSpeed Setpoint to the Electronic Governor.

Speed Controller (MCC and RTA)

The highly reliable Speed Controller controls the speed of the main engine by adjusting the fuel rack.The Electronic Governor consists of an Electric Actuator with Electronic Drive Unit and a Speed Controller. The Governoris operated via the CR Operator Panel in the control room console. The Speed Controller uses advanced control algorithmsin order to control engine speed. The Electronic Governor requires no maintenance and makes use of a brush-lessAC servo-motor. Three different sizes are available for engines with cylinder bores ranging from 40 to 120mm.The Electronic Governor provides accurate speed control of the main engine; even in heavy conditions like rough weather,wind-milling, minimum speed and failure of one cylinder.
