Bunker barges fitted with a flow meter should be checked for proper functioning by sighting a valid calibration certificate and ensuring the seal is intact.
There may also be unauthorised piping (by-pass lines) fitted to the flow meter running into the pump suction side and thus this un-authorised contraption will register the throughput of fuel twice through the flow meter.
Key Notes:
- Verify flow meter seal is intact
- Verify validity of the calibration certifcate and that it is for the same type flow meter
- Look out for any suspicious by-pass lines running after the flow meter
- Consult the barge piping diagram if in doubt
- Remember whenever in doubt or have concerns always issue a letter of protest
