GRS Georim GBA-155 OWS oils content meter. Calibration, repair, and commissioning services available onboard across major European and Mediterranean ports.
The GRS Georim GBA-155 is a Type OWS oils content meter designed to support reliable monitoring of oil in bilge water before overboard discharge. Built for marine environments, this instrument helps vessels maintain compliance while operating safely and efficiently.
The GBA-155 is known for its stable measurement performance, compact design, and compatibility with standard oily water separator systems. It is developed to meet international marine requirements and to operate continuously under demanding onboard conditions. The unit provides clear indication and alarm signaling to support crew awareness and operational control.
From the manufacturer description, the GBA-155 is designed for dependable operation with low maintenance requirements and is suitable for both new installations and retrofit projects. According to the technical documentation, key characteristics include continuous oil content monitoring, alarm activation at regulatory limits, robust marine grade construction, and integration with control and alarm systems.
To keep the instrument performing as intended, regular calibration and functional testing are required. Marine regulations under IMO, ISM, SOLAS, and SIRE 2.0 require that oil content meters and 15 ppm bilge alarms are calibrated at intervals defined by the manufacturer, with industry practice recommending calibration at least every 12 months using traceable standards.
