Dimensional drawing MCU Mark 6M 0806-1285
The Main Control Unit is the central part of the Oilcon
®
Oil Discharge Monitoring and Control System
and is designed for mounting in the cargo control console. Its function is to compute and record:
The instantaneous rate of discharged oil, in litres per nautical mile
The total quantity of oil discharged into the sea on each voyage
To control the ships overboard discharge system
The oil content
The Main Control Unit receives the following input signals to control the ship’s overboard discharge
system:
Ship’s GPS input
Ship’s speed in knots
Overboard valve position
Oil content of ballast water in ppm *
Rate of discharge of ballast water in cubic metres per hour *
Inputs marked * are received from the EPU via a serial data link.
The MCU processes these inputs and records and displays all the necessary information.
Figure 1
The data is displayed on the LCD touch screen and is also logged to an internal memory.
Control of the MCU is through the LCD touch screen.
The MCU also displays a number of menus with information about the system’s status, configuration
and settings. The various menus are designed to help the operator to control the Oilcon
®
Oil
Discharge Monitoring and Control System and to give a wide range of information.
