Long Distance Pipeline: Energy Transportation Lifeline
About
Character

•
•
•
•
Global energy demand grow 36% up to 2035
At present, 85% of the global oil transportation is by long range pipeline
In the future Pipeline will seek further expansion to meet the increasing crude oil supply
Serious environmental hazards: flammable, explosive, evaporable, diffusible, accumulative, poisonous,
Lifeline of nation economic: huge transportation capacity, continuous operation, high pressure, lack of
backup link, hard to repair
Lack of visibility: long distance, complex and harsh environment and major part invisible
2
Challenges of Long Range Pipeline Operation
“Know” it entirely
What need to be
done after
construction?
• make it possible to know what’s happening
throughout of the pipeline anytime and anywhere
•
real time performance monitoring
“Operate” it easily
A “naked”
pipeline can not
“run” well !
• make the pipeline controllable
• industrial mobility ensure that the most efficient
measure of on site collaboration is acquired to
deal with any occurrence
“Protect” it well
• Establish first responder capability to effectively
respond to emergencies and safeguard the core
asset of pipeline operation company
