Oil discharge monitor for ships (monitoring / recording / alarming)

The Bilge Overboard Security System (Increased Assurance Discharge Monitoring System, IADMS), from Rivertrace Engineering Ltd, has been developed out of repeated industry requests to provide a failsafe method of prevention against illegal oil discharge to sea.
Illegal discharges involving "Magic Pipes" and 'Empty' Oily Water Separators are seen as a major contributor to pollution of the seas and vessels are under increasing scrutiny by Port State Control (PSC) Surveyors globally.
The system is primarily designed to prevent illegal oily water discharge to sea and will record if one has taken place.
Equipment supplied under MEPC 107(49) has a degree of inbuilt increased assurance in that separator status is recorded along with time and date and it should not be possible for clean water to be used when in the discharge cycle, but even this record and control cannot prevent the "Magic Pipe" type of discharge.
For a system to be effective, all aspects of the discharge process should be monitored and recorded. The IADMS achieves this utilizing the separator control, oil content output, flow rate and cumulative flow through the discharge pipe and in addition records the ships GPS position, speed and track.
