Software & Technology: Liquids HCA Tool

EN Data Solutions, a sector of ENTRUST Solutions Group, empowers pipeline
operators to rapidly and efficiently determine “could affect” segments in
the event of a hazardous liquids release.

Understanding the transport and fate of hazardous liquids release plumes in
a terrestrial setting is a daunting task. Realistic simulation of such
release plumes is mathematically complex and computationally intensive. Some
liquids HCA software packages currently available are often inaccurate,
unscalable, or both.

A GIS DATABASE THAT IS EFFECTIVELY SUPPORTING YOUR OPERATIONS WILL:

• Results are consistent, reproducible, defendable
• All results stored in a structured Esri geodatabase
• Reduced processing cycle times
• Extremely granular understanding of consequence of risk

OUR APPROACH

The EN Data Solutions Liquids HCA Tool allows for rapid and efficient
determination of regulatory “could affect” segments in a way that is
consistent, reliable, reproducible, and defendable. The tool increases
accuracy via advanced computational fluid dynamics (CFD) algorithms. It also
takes advantage of modern virtualized, containerized computing. The Liquids
HCA tool connects directly to USGS web services to obtain topographic and
hydrologic data and utilizes Docker® and Microsoft Azure® for unlimited
scalability. The Liquids HCA tool works directly inside ArcGIS Pro,
providing increased flexibility over stand-alone applications.

The tool is designed to meet all the requirements for “could affect” segment
determination for hazardous liquids pipelines (crude, refned products, HVLs,
etc.), as specified in 49 CFR §195.452, Pipeline integrity management in
high consequence areas.

The most significant advancement of the Liquids HCA tool is its
state-of-the-art predictive modeling capabilities. Most industry tools rely
on the Manning Equation – an empirical equation designed to model) water or
mudflows. Instead, the EN Data Solutions tool relies on the Navier-Stokes
equation to model hydrocarbons, leveraging the GeoClaw engine from George
Washington University to more accurately model geophysical flows based on
friction factor determination

EN DATA SOLUTIONS DELIVERS:

The EN Data Solutions Liquids HCA Tool performs hydrocarbon plume transport
simulations that support the following product transport mechanisms:

Overland flow: Simulation of the hydrocarbon release plume
over the surface of the Earth, taking topography into account.

Hydrographic transport: Simulation of the downstream
transport of a hydrocarbon release plume that has entered a lake,
stream/river network or other water body.

ADDITIONAL BENEFITS INCLUDE:

• Esri® UPDM and Esri® APR, plus PODSTM, integration.
• Drain-down analysis including network topology for contributions from
  connected lines, identified sites, gathering places, and structure
  locations.
