Executive Summary
AK Transneft Oil Transporting JSC owns the largest oil pipeline
system in the world, with a total network length of almost
50,000 km. Transneft transports about 93% of the oil produced
in Russia.
EleSy started cooperation with Transneft in 1994. In 1998, EleSy
designed and commissioned the distributed data acquisition and
control system for Transneft, and won the Microsoft Windows World
Open award for the world's largest PC-based automation project.
Until now, the project has had no analogues of its scale in the
world.
In 2008, EleSy convincingly demonstrated its unified automatic
control system is suitable for the Eastern Siberia - Pacific Ocean
oil pipeline happening to become a general contractor and principal
system developer.
The pipeline is constructed to connect the oil fields of Western
and Eastern Siberia with the Russian seaports of the Pacific
coastwise and the spur pipeline to China, and to export Russian
crude oil to the USA and Asia-Pacific markets.
Challenges and Scope of Work
It was required to implement high-quality automatic control
system for the pipeline with the predicted capacity of 80 million
ton a year.
According to the project, EleSy was requested to design the
following:
Telemetry system for linear and station parts of the oil
pipeline
- Dispatcher system for the trunk oil pipeline
- Automatics systems
- Automatic fire-extinguishing system
Solutions
EleSy created a unified automatic control system for oil
pipeline based on InfinitySuite SCADA system being a continuous
process control tool for large scale geographically-distributed
facilities.
Oil pipeline operation is provided by EleSy's integrated
telecontrol solution including enclosed telemetery system and the
relay-type communication system installed inside the movable
container houses powered by diesel generators.
Oil pipeline dispatcher system provided by EleSy processes over
500,000 data points.
Advantages
The required instructions issued by the control algorithms based
on the ControlLogic PLC (from Allen Bredley) are transmitted to the
terminal devices through the InfinitySuite SCADA based trunk oil
pipeline dispatcher system. It allows the dispatcher to perform
on-line process monitoring. Algorithm controller processes
acknowledgement upon the instruction execution.
In old control systems, it was the dispatcher who launched the
pipeline and changed its operating modes by means of dispatcher
system mnemonic diagrams. In EleSy's unified control system all
possible pipeline operating modes and the mode switching are
processed by the control algorithms. To eliminate the risk of
emergency, EleEy provided various protection functions and
developed the algorithms to ensure the pipeline trouble-free
operation.
All pipeline operations are controlled by the same I/O server
allowing the dispatcher to monitor the algorithmic processes and
process equipment operation simultaneously using the customary
dispatcher control system mnemonic diagrams.
Results
In December 2009, the Eastern Siberia - Pacific Ocean oil
pipeline was launched. The Chairman of the Government of the
Russian Federation, Vladimir Putin, attended the event of pumping
the first batch of Siberian oil into an oil tanker.
