Customer upgrades clamp-on metering
Objectives
  • A major operator approached Expro looking for a metering solution for the produced water overboard line on a North Sea platform
  • To meet OSPAR regulations the customer needed ot upgrade their existing in-line metering

The customer intitially installed other flow meter types:

  • In line mag meter
  • Clamp on ultrasonic meter
  • Both meters provide unreliable flow measurements due to the high salinity, conductiivity and the presence of oil, fine sand and dissolved gas
  • Expro provided a non-intrusive permanent metering solution which had a measurement accuracy of (± 2%) which was well within the customer's requirements
Expro Excellence
  • Our customer was cautious in purchasing a third meter, however an Expro ActiveSONAR™ flow meter was initially provided on a temporary surveillance basis. The meter was clamped onto the pipe downstream of the pipe reducer and also positioned upstream on the in-line magnetic flow meter and on the flow line control valve, non ideal flow conditioning
  • There was no adverse effect on the Expro ActiveSONAR™ meter measurement due to the salinity, solids and or oil.  Expro's flow studio diagnostics demonstrated the presence of entrained air from the pumps
  • Subsequently the flow meter was integrated into the platform DAQ system to provide real time data
Value to client
  • Expro's ActiveSONAR™ meter provided a successful solution in providing metering where mulitiple flow meter types had failed previously
  • The customer was satisfied with the data provided onsite during the surveillance and decided to purchase the meter
  • The customer met OSPAR regulations with a measurement accuracy ± 2%
