Applicability: shipowners, ship operators, ship managers, ship masters and agents. 

Further to Class News 25/2011. In July 2019, the United States Coast Guard (USCG) issued a safety notice for bilge alarms relating to the model ‘BilgMon 488’ manufactured by Brannstrom Sweden AB.
The USCG reported instances of finding the stored data on older models of the bilge alarm to be corrupted, apparently due to the alarm’s back-up battery losing power and the lack of a replaceable battery.
IMO Resolution MEPC.107(49) requires 15ppm bilge alarms (oil content meters) to store data for at least 18 months and should be able to display or print a protocol for official inspections as required.

It is recommended that operators of ship’s fitted with this BilgMon 488 equipment should regularly check the accuracy of its stored data. Where the equipment is found to be defective, the operators should contact Lloyd’s Register and the manufacturer
