Cheniere

Energy is a dynamic integrated energy company 

based in Houston, Texas. The company operates the world’s 

largest receiving terminal for Liquid Natural Gas at the mouth 

of the Sabine River in Louisiana and the 94‐mile‐long Creole 

Trail pipeline, which was commissioned in 2008.

“Our goal right from the beginning was to build a state‐ of‐the‐art dataset to manage our pipeline, maintain 

safety and evaluate threats and risks.”

PIR/HCA ReviewPotential impact radius (PIR):means the radius of a circle within which the within which the

potential failure of a pipeline could have significant impact on people or property. PIR is determined by the formula r = 0.69* (square root of (p*d2 )), where ‘r’ is the radius of a circular area in feet surrounding the point of failure, ‘p’ is the maximum allowable operating pressure (MAOP) in the pipeline segment in pounds per square inch and ‘d’ is the nominal diameter of the pipeline in inches.

High Consequence Area (HCA):(2) The area within a potential impact circle containing—(i) 20 or more buildings intended for human occupancy; or(ii) An identified site.

“We wanted to see what Pictometry

could for us.  And we wanted to see the images they already had in 

their database on our corridor. It simply made sense  from a due diligence standpoint.”

The curious case of the 2‐family “barn”

During demo, entered the address in question with  POL

Using POL’s

built‐in toolset –

address was located;  zoomed in on oblique photo of the structure

Clearly seen were two electrical service boxes on the  wall and a trampoline in the back

Oblique image indicated the structure was most  likely occupied –

further investigation it was a two‐

family duplex

The “right”

angle for remote  structural identification

“As an additional quality check, I began using the  tool right away to review our entire pipeline corridor. 

And I found that new structures had been  constructed along the corridor. That confirmed the 

value of Pictometry”

How is Cheniere

using it today?

Mainstay tool for Pipeline Integrity Management  Program

Most structures along the pipeline are now readily  identifiable

GIS data classifying the structures can be validated  by using imported structural outlines

There will be situations that require on‐site  validation or “ground truthing”.

“Pictometry

Online has increased our confidence in  the accuracy of our data and helped us improve 

operational efficiency and integrity management.  When you consider all of the benefits, it’s clear that 

we’re getting a lot of value from the solution”
