Wärtsilä Hamworthy OWTP 1.0 m³/h

Wärtsilä Wärtsilä Hamworthy OWTP 1.0 m³/h is identified in the source list as a 15 ppm oily-water separator. It is installed in the engine-room bilge-treatment area and connected to bilge holding, recirculation, discharge and monitoring arrangements. Its purpose is to treat oily machinery-space bilge water before any permitted overboard discharge through the vessel's approved pollution-prevention system. The source record provides the stated capacity 1.0 m³/h. Separation stages, filter media, feed arrangement and oil-content monitoring architecture are model-specific and form part of the approved installation. The exact model designation and any source-listed capacity distinguish treatment throughput and internal configuration from neighboring OWS units; refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

●Separation-element fouling caused by sludge, detergents or excessive oil loading, resulting in poor separation and repeated high-oil-content alarms
●Oil-content monitor contamination or calibration drift caused by dirty sample lines or sensor fouling, resulting in unstable or implausible readings
●Automatic recirculation or discharge-valve failure caused by actuator, solenoid or control faults, resulting in inability to route off-specification water correctly
●Feed-pump or suction problems caused by blockage, air ingress or pump wear, resulting in unstable flow and poor separator performance
●Internal leakage or bypassing caused by damaged seals, incorrect assembly or unauthorized piping changes, resulting in non-compliant operation or abnormal sample results

Service & Maintenance

Inspect separator chambers, coalescing or filter elements, sample lines, oil-content monitor, automatic stopping or recirculation devices and associated valves. Keep bilge feed as free as practicable from detergents and emulsifying chemicals that can impair separation. Flush and clean sample lines and sensors according to the approved manual and verify alarms and automatic diversion functions after maintenance. Check the piping arrangement against approved drawings and ensure no bypass route compromises the system. Maintain required operating and calibration records. Refer to the manufacturer documentation for the exact figure for test methods, element replacement criteria and operating limits.
