Presentation Notes

Nalco Champion is a division of Ecolab. Which finds solutions to the world’s biggest challenges focusing on: Clean Water – Safe Food – Abundant Energy – Healthy Environments What do we do for our customers? Protect their investments and asset Maximize and secure production and throughput Help meet environment and safety specifications And how we do it is through specialized chemistry solutions, equipment for pipelines and water treatment, as well as our digital solutions that assist with understanding the operators system and its risks.

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

Field Data Collection

Desktop/Pro

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
