IMO Resolution MEPC 107 (49) came into effect on 1st January 2005 and applies to all new installations of oil content monitors within engine room spaces. This applies to existing ships and ships whose keel was laid on or after 1st January 2005. The Rivertrace Smart-Cell Bilge Alarm meets the requirements of MEPC 107 (49) for the monitoring of three oil types: fuel oil, diesel and emulsions. By utilising the Smart-Cell Detector Array Technology, developed by Rivertrace, the Bilge Alarm analyses all three oil types simultaneously without the need for re-calibration. Since optical cell fouling is recognised as a leading cause of monitor malfunction or incorrect reading a manual cell cleaning device is included as standard to simplify routine maintenance. By simple operation of the manual clean device, the Smart-Cell remains in optimum operating condition.
