Tricks of the Bunker Trade: Flow meter / Pipe work Tampering

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
