General Details

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 is laid on of after 1st January 2005. The Rivertrace Smart-Cell Bilge Alarm meets the requirements of MEPC 107 (49) for monitoring of 3 oil types: Fuel Oil, Diesel and Emulsions. By utilising the Smart- Cell Detector Array Technology, technology developed by Rivertrace, the Bilge Alarm analyses all three oil types simultaneously without the need for re-calibration. A manual cell clean device is included as standard to easily enable routine maintenance. Optical cell fouling is recognised as a leading cause of monitor malfunction or incorrect reading. By simple operation of the manual clean device, the Smart-Cell remains in optimum operating condition.
