OTD Technology Benefits: Improved Business/Operational Efficiency Enhanced Public Safety Improved Customer Service Environmental In These Key Areas: Integrity Management Public Safety System Risk Analysis & Assessment Methane Detection

Integrity Management - Tracking and Traceability Provides component level traceability with high accuracy GPS to locate specific fittings (manufacturer, lot #, etc.) Captures critical fusion parameters Captures pictures, sketches and other relevant installation data for complex configurations Streamlines operations Improves the quality and efficiency of data collection Eliminates GPS post-processing Enables regulatory compliance DIMP “Know Your System” Plastic Pipe Rule NPRM

Integrity Management - Field Data Collection Mobile applications with customized regulatory inspection forms GPS, sketches, pictures, and audio records Codes, standards, and procedures stored on the tablet Inspection results compiled into a database for reporting and export

Integrity Management - Field Data Collection Existing Collect GPS Data Hand Enter Asset Definition Bring Hardware Back to the Office Download Data Post Process Data Integrate Data into GIS System of Record New Create Gas Asset in Field Post to GIS Version Asset into GIS or System of Record

Integrity Management - Fusion Data Collection Poly-fusions can be performed using the custom-designed butt-fusion machine A machine has custom-made control software and interface which allows for complete data logging and control of fusion parameters

Public Safety - Mitigating the Risk of Cross Bores Cross Bore Best Practices Guide Single-source of information for natural gas operators to investigate and remediate existing cross bores as well as prevent future cross bores Cross Bore Outreach and Education Program Information to effect positive changes in attitude, practices and operations Technology Development Acoustic Pipe Locator (APL) Mechanical Spring Cleanout Safety Device www.otd-co.org

Public Safety - Excavation and Encroachment Safety GPS-Based Excavation Encroachment Notification GPS tracks excavation activity in relation to assets and one-call tickets Provide real-time notification of encroachment New pilot projects High-accuracy GPS for excavators and pipe locations Application—DOT projects

Public Safety - Breakaway Fittings for Meter Safety Breakaway disconnect/ shutoff fitting for meter set assemblies (MSA) and other aboveground gas systems Reduce the risk of vehicle collision and ice or snow falling from a building Commercially available in 2017

Public Safety - Kleiss Flow Stopping System Inflatable Stoppers: an alternative to currently employed stopping equipment for use on pipes up to 18” in diameter and pressures up to 60 psig for the following pipe types: Vintage PE susceptible to cracking Large diameter thick-walled PE Cast iron Steel PE PVC pipes No-blow operations Small fittings with taps up to 3” Lightweight equipment Alternative to squeezing PE pipe

Risk Analysis - Pipe Testing Verification Aldyl-A and Vintage Pipe Testing Process Identifies possible issues associated with specific vintages and/or areas of Aldyl-A or other vintage pipeline installations This information, combined with existing known system information (i.e., age, leak data, failures, etc.), will assist utilities in identifying and prioritizing pipe replacement programs

Intrinsically Locatable Technology for Plastic Piping Systems (U. S Intrinsically Locatable Technology for Plastic Piping Systems (U.S. DOT / OTD / 3M) Objective Develop and test a viable solution for intrinsically locatable polyethylene (PE) materials with an integral electronic marking system. Partner with 3M Company and a large pipe manufacturer to develop the electronic markers and attach the marker to PE pipe. Focus Complete the development, define and test the electronic marker capability, validate the attachment design, and perform laboratory and field testing.

Risk Analysis – System Assessment Effective Process Effectiveness Technology Efficacy Staff Quality Consequence of Failure Risk = Total Losses Likelihood of Failure Procedure Quality The Enterprise Decision Support System combines: Expert systems Pattern matching Diagnosis of failures Complex system risk assessment Reasoning under uncertainty Scientific rigor Scenario analysis

Methane Detection - Remote Gas Sensing and Monitoring Objective: To create a device that remotely monitors the level of gases during emergency gas leak situations Need: First responders need a tool that enables the monitoring of methane, CO, and other gases in a local area Remote monitors can be placed in each home and confined spaces Remote monitors transmit data to onsite personnel, providing concentration levels in real-time Approach will enhance the safety of first responders and the general public

Methane Detection - Residential Program Customer behavior suggests that odorant alone is not enough for customers to report leaks Recent events have heightened the focus on how unreported leaks can result in tragic outcomes Having an alert system, such as a residential methane detector, benefits both the customer and the utility

Methane Detection - Technology for Low-Cost Methane Sensing Better data-collection and measurement of methane emissions will enable quicker emission reductions Provides accurate count of emissions Ranks high-priority sources Low-cost methane sensing technologies can enable widespread deployment for infrastructure assets GTI and commercial partners are developing a measurement system based on new technology to detect methane and better estimate the location and intensity of methane leaks

Leverage of Resources—PHMSA Co-funded R&D Projects
