PipelineOffice® Liquids HCA
Geonamic offers a complete software and service solution to model and quantify impacts of a hazardous release from liquids pipelines- PipelineOffice® Liquids HCA. Accurate modeling of worst-case release volumes, product dispersion over land, product dispersion through surface water, and resulting impacts to sensitive areas are all supported by this powerful software, providing invaluable assistance to dozens of liquids pipeline operators over the years to help identify and assess pipeline segments that could impact high consequence areas.
Advanced Emergency Flow Restriction Device (EFRD) modeling capabilities and services are included to identify optimum locations for new EFRDs and to quantify the associated volume reductions and reduction in impacts, as well as dynamic reporting tools to support validation of HCA and EFRD results.

Liquids HCA Analysis Services- Flexible and Configurable
Geonamic staff have extensive industry experience providing Liquids HCA Analysis services that align with client Integrity Management Plans and successfully meet regulatory requirements. Our core methodologies and technology are comprehensive and unmatched, providing defensible results in a format tailored to integrate with client asset and integrity data models.
Our typical Liquids HCA analysis process starts with in-depth discussion and collaboration with clients about choosing the right input data and model settings. Geonamic’s PipelineOffice® Liquids HCA is highly configurable to client requirements and can be easily adapted to support new and improved input data. Some of the most popular configurable items include buffer calculation for aerial dispersion, spill volume calculation, and elevation data for detailed facility/tank HCA’s overland spread modeling. Our exhaustive QC process also identifies any potential input data issues.
EFRD Analysis Best Practices
Geonamic’s PipelineOffice Liquids HCA includes a high-performance and proven algorithm that supports efficient EFRD analysis and iteration. The software includes several configurable options to tailor to the client-specific goal for each analysis and looks for the best candidates, producing three candidates for each proposed new valve. EFRD scenarios based on existing valves or placement of new valves can be defined and each scenario’s before and after volumes can be easily compared with the software’s robust, interactive charting capabilities.
Software or services can be customized to meet client-specific goals for EFRD analysis. The analysis can be generalized to focus only on maximum spill volume reduction, or can be used to quantify HCA impact reduction based on the reduced volumes. Each pipeline is different, so clients can choose an approach that is most applicable. For example, if a pipeline has a 100% direct HCA impact, an EFRD will not reduce HCA mileage but could reduce the maximum volume released inside HCA. In addition, we can target elimination of impacts to specific HCAs or types of HCAs if desired (HPOP or OPOP, for example).
Diving deeper into Liquids HCA Analysis- PHMSA Coastal Eco Data Case Study
In recent years, PHMSA has issued a final rule regarding unusually sensitive areas for the Great Lakes, coastal beaches, and certain coastal waters leading to new mapping and creation of a dataset called the “Coastal Eco dataset.” Operators are now faced with the challenge of incorporating this updated data and amended regulations into their integrity management programs. The original Coastal Eco dataset downloaded from PHMSA was directly derived from extreme high resolution raster data, causing some difficulties in HCA analysis and geoprocessing- Geonamic was up for the challenge.
We addressed this by pre-processing the Coastal Eco data and dicing complex geometries into smaller pieces, setting up a vertex limit for an output diced polygon feature class. In this case, the overall outline shape of the Coastal Eco dataset was preserved while the pipeline intersected with smaller and simpler pieces of Coastal Eco each time during the HCA analysis process, leading to faster and better computational performance.

Introducing: Hourly Release Trace of Spill Plumes
Our software not only presents aggregated results by HCA Impact Method (Direct Impact, Aerial Dispersion, and Potential Impact) and by HCA impact Type (HPA, OPA, ECO, DW, CNW, and Coastal ECO), but also has a new and exciting feature that we’re excited to announce.
PipelineOffice Liquids HCA can now automatically generate water transport plumes for each hour into a separate layer. This functionality empowers end users to visualize an hourly release trace in a gorgeous, user-friendly map view interface. Note that the above screenshot used a default of 12 hours and therefore there are 12 layers generated. Contact us today to learn more about incredible addition to our Liquids HCA module!
Aerial Dispersion Analysis
For HVL product types, Geonamic can use client-provided Distance to LFL values for this component of HCA analysis. In addition, we offer services to calculate these values using industry standard aerial dispersion models – including CANARY and ALOHA.
