PAKISTAN PETROLEUM LTD KANDHKOT FIELD NATURAL GAS PIPELINE SCADA SYSTEM:
In 2001, TRC was awarded a contract to provide
a SCADA System for Pakistan Petroleum Ltd to monitor and control their Kandhkot
Natural Gas Field operations. The SCADA system consists of one (1) poller/server
PC (main terminal unit – MTU), six (6) new RTU stations and six (6) interface to
the existing Moscad RTUs. The SCADA Control Room was located in the Dehydration
Plant – DHP and the six (6) new RTUs are installed in the wells 6, 10, 11, 17, 23
and 12.
The MTU uses Wonderware InTouch MMI software to collect data from the new RTUs via
VHF radio communications and to interface with the existing Moscad FIU in the same
control room to collect the existing RTU stations’ data. Pressure, temperature,
flow rate, valve status, CI pump status and other signals are collected from the
wells. The Moscad FIU is used to collect data from the existing Moscad RTUs via
VHF radio communications and pass this data to the SCADA MTU over a serial link.
The Integra TR radios from DataRadio Corp. were used to establish the VHF radio
links between the control room and the new wells.
The new RTU stations are based on Modicon Compact RTUs with AGA-3 capability.
Fisher-Rosemount static, differential pressure and temperature transmitters are
used to collect field signals.
TRC was responsible for the design, engineering, system configuration, software
development, system integration, and test and installation supervision and commissioning
of the system
