Introduction
Purpose Share a solution developed through collaborative efforts between NALCO Champion and
G2 that was designed to identify internal corrosion risk threats, in order to align mitigation strategies.
Process Outline pending PHMSA regulations Review process for collecting data, analyzing and displaying results with Esri tools Explore future objectives
Payoff Gain an understanding of how Esri applications and our industry expertise can be utilized
to identify internal corrosion risk threats and help our customers ensure regulatory compliance by protecting the public, environment and assets.
Pipeline Regulations
2017 Gas Pipeline mileage per PHMSA Reg. Transmission: 300,617 Reg. Gathering: 18,155 Non-reg Gathering: est. 400,000+
Mega Rule implications 50,000 – 100,000 miles of previously
unreported gathering lines will be subject to CFR Part 192 regulations
Internal corrosion existing regulations §192.475 Internal corrosion control: General.
§192.476 Internal corrosion control: Design and construction of transmission line.§192.477 Internal corrosion control: Monitoring.
49 CFR Part 192 Subpart O Gas Transmission Pipeline Integrity Management
§ 192.475 Internal corrosion control: General.(a) Corrosive gas may not be transported by pipeline, unless the corrosive effect of the gas on the pipeline has been investigated and steps have been taken to minimize internal corrosion.
Internal Corrosion
Solution developed to effectively assess IC threats to establish preventative and mitigative measures for risk reduction Field personnel collect IC data along the
pipeline system Perform industry-based algorithms to
determine level of risk Provide customized reporting for strategic
decision-making Provide IC risk analysis on historical,
current or future pipeline operating conditions
Assist with risk reduction and economic decision strategies for corrosion control and mitigation

PrepareData for
Processing• Work with Pipeline Operator
to gather enterprise GIS data• Condition data as needed
• Perform field tests and acquire test samples at each inlet/outlet site
• Log field test data using ArcGIS Collector
• Risk model based on industry standards including NACE, ASME, PHMSA, etc.
• Dynamically segment pipeline at each inlet/outlet
• Risk results are published and viewed via AGOL and Insights for ArcGIS• Internal corrosion preventive
and mitigative measures to be introduced to lower risk
Desktop/Pro
Field Data Collection
Meet with Operations, Measurement, Regulatory and other relevant departments at client office to review existing data, identify any data gaps and understand the expectations
Modify and prioritize risk algorithm variables if required based on pipeline operators priorities, risk methodologies and history
Clearly define internal corrosion field testing and sampling requirements and procedures
Nalco Champion internal corrosion specialist and company representative perform field tests and acquire test samples at each inlet/outlet site, where feasible
Collect and log field test data using ArcGIS Collector and upload on location, if possible
Process Data
Run the risk model using data collected from the field and the Enterprise GIS Esri Desktop tools
Model Builder Python Scripts
The process performs the following: Snaps field collected data to centerline Dynamically segment centerline with
Enterprise GIS Runs Risk Algorithm to assign risk threat
levels
Data Analytics
Pipeline is dynamically segmented between the inlets and outlets along the system, where the flow conditions and product composition can affect the internal corrosion risk threat
Output contains: All input attributes collected from the field
and from the GIS Calculated risk threat levels for each internal
corrosion risk factor Calculated
Consequence of Failure (COF) Likelihood of Failure (LOF) Risk of Failure (ROF) = LOF x COF
Display Results
Results can be published to ArcGIS Online or Portal
Leverage Insights for ArcGIS for data analysis and trending
Create Web Map Application for viewing and querying results
Based on the results, preventative and mitigative measures (P&MMs) can be implemented and the effectiveness of the IC risk reductions can be monitored and tracked over time
Mitigating the Risk
More frequent internal corrosion control mitigation and maintenance activities;
Enhanced monitoring of internal corrosion systems
Sampling
Additional monitoring points
Enhanced pigging program
Improve internal corrosion control systems
Corrosion inhibitors and/or biocides, dehydration, gas sweetening
Eliminate or reduce the source of internal corrosion risk threat
Monitor, replace or repair the pipeline
Future Objectives
Hazardous Liquids IC Risk Modeling An analytical process that integrates relevant internal corrosion (IC) information about
pipeline integrity and the consequences of a failure Advanced Pipeline Risk IQ
Include “What if” scenario capabilities Incorporation of Nalco Champion Laboratory Analytical database to validate chemical
treatment effectiveness P&M Measures Validation Analysis to In Line Inspection Data
An analytical evaluation by aligning identified high IC risk line segments with ILI data to validate the effectiveness of IC treatment programs
Internal Corrosion Direct Assessment (ICDA) – NACE SP0110-2018 SG & NACE SP0206-2016 SG
An integrity assessment process conducted for the purpose of locating and remediating anomalies arising from internal corrosion of a dry gas or wet gas pipeline
