RD-ODME-IIA Oil Discharge Monitoring System
The ODME is used to monitor the oily water discharging from ballast tank or other pollution water into the sea.The system constitute by the discharge monitoring unit, sampling analysis unit, discharge remote control unit etc.
The ODME is used to monitor the oily water discharging from ballast tank or other pollution water into the sea. The system constitute by the discharge monitoring unit, sampling analysis unit, discharge remote control unit etc. When the ballast tank or other of oily water discharges, the discharge monitoring unit will monitor instantaneous oil content by sampling analysis unit and command the discharge remote control unit will let out oily water or return to the slop tank according to the ship speed. All the discharge data have monitoring
The computer unit is the control center of the system. The computer reads the data of the actual oil content from oil content measuring unit by communication loop, and to calculate out the instantaneous rate of discharge and the total quantity discharged based on the signals of the speed log and the flow meter received. When the total quantity discharged or the
instantaneous rate of discharge is over the specified limit, or the system faults during operation, it will send an order to close the overboard valve, and to stop the discharge of oily water.
In addition, the signal input mode or the signal value inputted by manual can be selected on the Man-Machine Interface of computer.
In oil content measuring unit, a measuring cell (oil content meter) is provided, which is equipped with optical elements for measuring oil content in sampling water. The sampling water coming from sampling pump enters into the inlet of oil content measuring unit and flows back to main discharge pipe from outlet. The oil content meter converts the oil content variation in the sampling water passing through the measuring unit to the rS485 data, then the oil content data is transmitted to the computer unit.
