CNPC Oil Depot

Project Challenges

  • The CNPC Northwest Sales Center Xigu Oil Depot was reconstructing to support real-time data acquisition from the control system, the operation of the railway loading bridge, and the Beitan Oil depot.


  • The client chose an ISA100 Wireless network that included support for the mobile work station.  20 wireless pressure transmitters, 5 multifunctional nodes, and 4 mobile work stations/RESS Servers were installed around the site.
  • The wireless network architecture supported 3 wireless applications simultaneously:
    • Supported 4 mobile work stations to realize on-site mobile operation, real-time browsing of PKS control system picture, configuration, report and alert, and entry of process data.
    • Supported communication with 20 wireless pressure transmitters and process data monitoring.
    • Supported wireless communication between Beitan Oil Depot measuring system and Xigu Oil Depot PKS control system.


  • No need to add costly cabling and cable bridges, enabling a fast commissioning time.
  • Complete integration of the wireless system with the control system, including wireless network management functions, helps users maximize operational efficiency by constructing the tank field in a highly efficient manner.
  • Remote wireless access to real-time data and control system information.
