Oil pumping

The submersible pump system of the oil production platform consists of an ABB frequency converter and a squirrel cage motor, plus a step-down and a step-up transformer. The frequency converter controls the motor speed by changing the frequency of the supply current. The motor speed can therefore be adjusted according to the flow from the oil well and the oil can be pumped continuously. Settling of solids, accumulation of paraffins and cavitation are minimal. Maintenance, servicing and energy costs are reduced, and the pumping system is considerably more reliable.


Submersible pump system of oil production platform.

Solved Problem

• High stress on pipeline and pump
  
• Pump cavitation caused by accumulation of solids
  
• High energy consumption

• Frequency Converter: 810 kVA, 690 V
  
• Motor: 295 kW, 3600 rpm, 690 V
  
• Step-down transformer: 630 kVA, 6600 V/693 V
  
• Step-up transformer: 500 kVA, 660 V/2300 V

• Lower maintenance costs due to reduced mechanical stress
  
• Reduced energy consumption due to optimum pumping
  
• More reliable operation because of minimised accumulation of solids
  
• Pumping capacity increased by up to 25 %
