31.OWS checks

October 08, 2018 Posted by AK No comments
While maintenance is being performed inside the OWS, do not damage the anti-corrosive surface (normally provided where the liquid is in contact with the body) by doing welding or brushing.

Keep checking the back pressure for the coalescers and if the pressure exceeds the rated pressure, renew the same.

Periodic cleaning of OWS to be performed by removing any water scale, sludge, dust, bacteria etc. from the internal surfaces.

Clean the oil level sensor electrode at regular interval.

A filter is installed on the sample water inlet to prevent fouling by foreign objects which may cause measuring error. If the flow of sample water is insufficient, remove and clean the filter.

The solenoid valve may malfunction due to fouling,which may occur after a long period of operation. The solenoid valve must be cleaned at regular interval.

The outlet pipe of the OWS (distance pipe between OWS and overboard discharge valve) should be opened up once a month to check for traces of oil. If found, it can be because OCM is malfunctioning or misoperation of OWS is being performed.

The alarm and function of the three way valve and other solenoid valves must be checked every week.
