High longitudinal stresses in pipelines can be a major contributor to failures of girth welds and circumferentially oriented flaws. These high stresses are frequently associated with construction and maintenance activities, such as excavation and backfill in new construction, pipe replacement, and integrity digs. There are currently no industry-wide guidelines for the management of construction- and maintenance-related stresses. The objective of this project is to develop such guidelines by extracting and streamlining the best practices from pipeline operators and other sources.

The Risk Treatment Strategies for Circumferential Cracking provides guidance for evaluating risk, investigations for uncertainty reduction, determining a Risk Reduction Decision Type to inform selection of a risk reduction approach, and the full depth and variety of risk reduction options that can be deployed, subject to ranges of applicability.

This project surveyed project member companies for recompression data during their day-to-day operations. This data was compiled and incorporated into the conceptual design of cost-effective packages aimed at maximizing value without compromising throughput. Major components in each package were selected, sized, and costed. A technoeconomic tool was developed to assist pipeline operators in assessing the technical and economic tradeoffs of each package. Each package was then evaluated using this tool to assess its competitiveness against existing commercial off-the-shelf (COTS) recompression units.

This webinar provides an overview of PRCI project NDE-2-15 Selective Seam Weld Corrosion (SSWC) Identification and Measuring Grooving Ratio in the Ditch. SSWC is a narrow form of corrosion occurring at the pipe long seam and results from different corrosion resistance characteristics being present in the seam when compared to the pipe body. This form of corrosion can produce metal loss cross-sections (CS) that are very challenging to resolve with current non-destructive evaluation (NDE) methods routinely used in-the-ditch for typical metal loss evaluations. Since the shapes of natural SSWC are known (in many cases) to not conform with the conditions prescribed by laser profilometry manufacturers as valid for their published performance specifications, an investigation into the actual NDE performance of various techniques is required to fill the industry gap. In addition, SSWC has been known to fail at burst pressures significantly lower than would be predicted by commonly used corrosion-based assessment models which are indicative of a plastic collapse failure mode. This observation implies that SSWC can fail in a crack-like manner, and as a result, NDE techniques that are commonly used for crack characterization should be considered as potentially viable NDE technologies when searching for the most accurate NDE technique for validating inline inspection (ILI)-based SSWC calls in the ditch.

This webinar documents the first phase of a multi-phase research initiative aimed at supporting the evaluation and selection of optical imaging technologies for methane emissions detection, localization, and quantification (DLQ). The project team conducted a targeted literature review and industry survey to identify current performance gaps and operator needs, which informed the development of a flexible, field-ready testing and validation protocol.

This webinar compiles information regarding known factors, components, and conditions associated with internal corrosion of natural gas metal pipe. It supplies context to the topic and background information for natural gas and RNG. Corrosion mechanisms and combined effects are described. It is clear that water is the most important factor for pipeline corrosion; corrosion mechanisms will not occur without the presence of water. This is true both of natural gas and RNG systems. Other major components contribute to corrosion in the presence of water, individually and in combinations, and the process is complicated and variable. Unless the pipeline system is completely devoid of water, there is no circumstance, with natural gas or RNG, which assures a corrosion-free environment. All constituents which contribute to a corrosive environment must be controlled as best possible, at all times, and well-constructed corrosion management programs should monitor internal pipe conditions.

This webinar provides an overview of PRCI project NDE-1-10A Hydrogen Cracking Integrity Management. The project and associated report describe the hydrogen cracking mechanisms of hydrogen blistering and hydrogen embrittlement. Based upon the industry's understanding and case studies reviewed, in-line inspection (ILI) strategies for two hydrogen-related cracking threat scenarios were developed. The ILI strategies rely upon a susceptibility determination in accordance with the guidance offered in previous PRCI work. The susceptibility determination methodology relied upon in this work was benchmarked using pipeline segments for which the presence of a significant threat of hydrogen-related cracking in pipe body hard spots was known.

This webinar summarizes the current and anticipated near term capabilities of various nondestructive technologies for describing the toughness of steel pipe and pipe seams. The technologies reviewed include multiple variants of instrumented indentation testing, the MMT Blade Toughness Meter (BTM), the MMT Hardness Strength and Ductility (HSD) method, small punch test (SPT), in-line inspection (ILI), electrochemical methods, ultrasonic methods, and various algorithms (models).

This webinar summarizes the project findings noted in the final report:

This report aims to identify and evaluate technologies capable of detecting and quantifying "super-emitter" methane leaks, defined as emissions greater than 100 kg/hr. These large-scale leaks are a significant contributor to total methane emissions and a growing focus for regulatory compliance. The primary goal of this project was to determine which technologies are best suited for macro-scale detection and measurement in hydrocarbon transmission and storage settings, and to develop a draft protocol for future field validation.

This webinar explores the application and integration of computational pipeline monitoring (CPM) technology in gas transmission pipelines, a domain where its use is not yet widespread. The primary objectives of this research include assessing the current state-of-the-art in CPM technology for gas pipelines and identifying best practices for its implementation on previously unmonitored segments. CPM technologies use real-time SCADA data to detect anomalies indicative of leaks, with a focus on enhancing leak detection accuracy amidst challenges presented by gas compressibility and transient flow conditions

The purpose of this Webinar is to summarize additions to the Microsoft® Excel® Spreadsheet tool developed in project number IM-1-06 for the practical implementation of the measurement performance validation methodology outlined in the API RP 1163 2021 Edition (API 1163-2021). The addendum covers the following new features

· Crack and Dent Assessments: the spreadsheet has been updated to consider the additional data columns and attributes necessary to assess the ILI measurement performance of cracks and dents. The updates include incorporating field measurement errors, the ability to input both length and depth measurements, and handling data subsets.

· Field Measurement Error: field measurement error is characterized by a ratio of the ILI to field error. It is modelled as either a systematic bias or a linear regression.

· Subset Data: multiple subsets of data can be analyzed separately. Incorporating data subsets allows operators to compare the measurement performance for categories of interest.

· Simplification of the Probability of Identification: POI has been simplified by assuming the field-identified anomaly type is correct. The POI is calculated for each anomaly type in the dataset.

· Expansion of Level 2 and Level 3 Tests: the null hypothesis and tolerance interval estimate methods have been expanded to perform retrospective analysis of the Level 2 test and one-sided Level 3 tests.

· Burst Pressure Comparison: the spreadsheet has been updated to include additional data inputs for comparing the Failure Pressure Ratio (FPR) estimates derived from ILI measurements and field measurements.

Nondestructive evaluation (NDE) is a critical element of safe and reliable operation for various industries, including oil and gas pipelines. Across industries, differences in materials, regulatory environments, production scales, and other factors influence the types of NDE that industries use and are working to develop. A review of NDE technologies used in the nuclear energy, power generation, aerospace, and automotive industries was completed. Technologies identified by this review with potential for advancing pipeline NDE are discussed in the report, and high-level steps are described for technology transfer and the adaptation and further development needed for application to pipelines.

This webinar describes the work undertaken to numerically model the hydrogen diffusion in in-service fillet welds across a wide variety of pipe attributes, welding conditions, and thermal conditions. The document includes recommendations for post-welding nondestructive examination (NDE) delay times that correspond to time-to-peak-hydrogen (TTPH) and time-to-critical-hydrogen (TTCH) at four common locations around a fillet weld where hydrogen induced cracking is likely to occur.

This project explores the use of sealants for in-situ valve repair. An experimental apparatus was designed and fabricated for evaluating valve leak repair. A controlled leak was created on a 6" ball valve and the sealing capability of multiple sealants was evaluated.

This research report seeks to advance the industry's knowledge and understanding of CT for pipeline applications. Multiple pipeline samples with various crack and crack-like features commonly found in gas transmission and hazardous liquid pipelines were examined with non-destructive examination (NDE) techniques, scanned with CT, and characterized by Destructive Testing (DT). Through the examination and discussion of the results, a more thorough understanding of the capabilities and limitations of CT for pipeline applications is achieved. In addition, a scanning protocol that is designed to achieve more consistent and reliable data from CT on pipeline samples was developed and is presented.

Flood related channel bed erosion, bank migration, and channel avulsions can represent a significant threat to pipeline integrity. Because there is well over 100,000 miles of liquid petroleum pipelines across the United States, the number of pipeline water crossings at risk from potential flood related forces is equally large. However, the vast majority of these pipeline water crossings are located on small rivers and streams that do not represent a significant threat to pipeline integrity. Conversely, understanding which rivers have the potential to impact pipeline integrity is critical for pipeline companies to continue to safely and reliably operate and to efficiently mitigate and manage flood related risks. The project described here is intended to support PRCI member companies by integrating and normalizing historic and future riverine related assessments conducted by pipeline operating companies into a central system allowing for visualization and data management of river risk properties and characterization to assist pipeline operating companies to better understand and evaluate riverine related risks to pipeline networks and scheduling of future inspections and setting post-flood inspection thresholds.

Selective seam weld corrosion (SSWC) is a form of corrosion attack that preferentially occurs along the weld bond line/fusion zone of linepipes. SSWC is an integrity threat mainly for vintage pipes, particularly those manufactured before 1970 using ERW (DC-ERW and LF-ERW) and flash welding. SSWC has resulted in multiple pipeline failures. Assessing the significance of SSWC, e.g., producing a reasonably accurate prediction of burst pressure of a pipeline segment containing SSWC, remains a challenge for the pipeline industry.

This project consists of four major parts:

Review prior work on burst pressure prediction,_x000D_

Evaluate the performance of current burst pressure models against the 12 SSWC failures described in a previously published report,_x000D_

Use a first-principles approach to examine the relative impact of factors affecting the burst pressure prediction of SSWC, and_x000D_

Develop directions for improving burst pressure predictions for pipeline segments containing SSWC._x000D_

The evaluation of the current burst pressure models enables the understanding of their limitations and the potentials for improvements. The examination of various factors affecting burst pressure prediction allows the identification of major factors that must be incorporated into future burst pressure models for accurate burst pressure prediction. The outcomes of this work provide clear directions for future model improvements.

This webinar details the laboratory testing program conducted to assess the operating range of the spot-weldable vibrating wire (VW) strain gauges with a specific focus on most commonly used strain gauges for pipeline monitoring. These strain gauges are commonly used by the pipeline operators for long-term monitoring of a change in the pipe strain due to geohazard activities. The primary goal of the laboratory testing program was to assess the response of these strain gauges within the operating range and their behavior as they approach or exceed the manufacturer-specified operating range. This study aims to provide pipeline operators with a framework for evaluating the strain gauge data and to differentiate between the measured strain changes due to geohazards or the measured strain changes due to other environmental factors, instrument malfunctioning, or erroneous readings which may not be related to geohazards.

This study evaluated various strain gauges with total operating ranges from 2,500 to 10,000 microstrain. In this webinar, principles of operation for vibrating wire strain gauges, examples of responses from vibrating wire strain gauges installed on the pipeline, materials and methods used for the laboratory testing program of bending plate tests, results of the laboratory test and strain gauges responses during these tests, and summary of findings are discussed.

This webinar describes the work completed on modelling the dynamics of the brine string in Solution-mined caverns in salt formations, under excitation by the inner fluid flow and the reverse external axial flow around the brine string. Specifically, two flow configurations are studied: Configuration 3, in which the fluid flows down the brine string, discharging at its free end; this forces fluid in the cavern to flow upwards in the annulus around the upper end of the string. In Configuration 4, the flow directions are reversed.

This webinar describes the ultrasonic meter manufactures' diagnostic ratios used to quantify operating changes and describes any major differences in how the meter design affects these ratios. These comparisons are summarized in a simple comparison table along with a table of manufacturer recommended diagnostic limits.

Manufacturer diagnostics reports have been added to the PRCI Ultrasonic Meter Test Results Database available on the VTDC. This database can be used for several purposes. Users can compare the extent to which different meter designs compensate for the arbitrary 3-dimensional flow fields caused by flow disturbances. Users can also evaluate the ability of manufacturer diagnostic limits to identify when the disturbances exceed the meter's compensation capabilities. And finally, the database provides the ability to compare the advantages of replacing the manufacturer's diagnostic with RSS risk diagnostics that monitor and report the same changes as statistical uncertainties that can be used to prioritize and action design and operating problems.

This Webinar builds on and supplements existing mechanical damage (MD) assessment and management tools, developed on behalf of Pipeline Research Council International (PRCI), Interstate Natural Gas Association of America (INGAA), Canadian Energy Pipeline Association (CEPA), American Petroleum Institute (API), other research organizations and individual pipeline operators, many of which are included in API Recommended Practice (RP) 1183 (1). Since the assembly of API RP 1183,

The objective of this project is to validate the existing mechanical damage (MD) assessment and management tools based on in-service field dents data provided by pipeline operators. The data provided included in-line inspection (ILI), dent geometry data, operating pressure history data and in-ditch inspection observations. The dent fatigue life analysis tools were developed on behalf of Pipeline Research Council International (PRCI), Interstate Natural Gas Association of America (INGAA), Canadian Energy Pipeline Association (CEPA), other research organizations and individual pipeline operators and are included in API Recommended Practice (RP) 1183 (1). Since the assembly of API RP 1183, PRCI has continued its mechanical damage strategic research priority in the development of a greater understanding of the behavior of mechanical damage and the pro duction of data to support engineering assessment. The research work included the following series of tasks: · Collect and collate mechanical damage field data provided by various pipeline operators. · Implement the fatigue life screening and assessment approaches using the provided dent geometry and pressure loading data. · Validate the fatigue life assessment results against the in-ditch inspection data. The data included presence of through wall cracks in dents resulting in leaks, location of surface cracks within dents and co-incident features like welds, corrosion, or gouges.

Risk management has been recognized as an essential decision-making tool in the pipeline industry over the past decade. However, there are still knowledge and process gaps that prevent broader implementation by industry stakeholders. The work described herein generated a gap analysis on risk management practices in the pipeline industry to define a future project roadmap that will be used to fill in the information, knowledge, and process gaps and to advance the application of risk management in the industry. A worldwide literature review of pipeline risk management practices was conducted, and industry inputs were collected through surveys and workshops. These tasks identified gaps in various technical area of risk management practices, which were then used as a basis to develop the scope, timeline, and funding requirements of the 10 potential projects in the related research roadmap.

This study identified an array of technologies spanning aero performance improvements (including inlet guide vanes, re-wheeling, restaging, and casing treatment for the gas turbine drive), integrated system improvements (including waste heat recovery, absorption chillers, and gas turbine-turbo-expander recovery systems), and optimized use of assets (including station configurations with parallel and series flow capabilities, operating with multiple smaller compressors, and using genetic algorithm-based systems to optimize fuel usage)._x000D_

This study also conducted three case studies considering compressor re-wheeling, compressor re-stage / replacement, and pre-cooling the compressor inlet gas. Each was evaluated over a 5-year historical data set from a natural gas pipeline operator.

This webinar describes a study identifying the uses, best practices, problems, and nuances of mechanical seals in liquid pipeline systems. The study is conducted by relying upon publicly-available literature, vendor interviews, and pipeline operator interviews to synthesize information about mechanical seals ranging from their basic definition and construction, to commonly used seal piping plans, common mechanical issues, and best practices to specifying new seals and troubleshooting current seals.

?This project addresses the pragmatic application of the new DOT/PHMSA MegaRule RIN 1 - 192.712 for recommended toughness values for determining if an ILI-detected axial flaw needs repair or can instead be observed for any future growth. The MegaRule toughness is expressed as the Charpy energy value, which came from Charpy test data at 50°F. However, the fracture toughness of a surface-cracked pipe is quite different than Charpy impact toughness values, es pecially if the Charpy data is in the brittle-to-ductile transition region. The surface-cracked pipe burst-pressure transition temperature can be considerably lower than the Charpy impact speci men transition temperature due to loading rates and constraint effects (bending versus tension loading). In cases with axial surface cracks in vintage base-metal pipe tests, the surface-cracked pipe burst pressure transition temperature was >200°F lower than the Charpy transition tempera ture. The procedures were extended to welds, and databases from member companies were ex amined to establish what Charpy energy values should be used to reflect the toughness of a sur face crack in the pipe at the operating temperatures and still be consistent with the MegaRule Charpy information and safety desires. As a result of this work, the following three Material Categories were identified. · Material Category 1 - All vintage base metal [these always had ductile initiation at nor mal minimum design operating temperatures, i.e., 50°F (10°C) and even 23°F (-5°C)]. · Material Category 2 - Most welds and HAZ (these also had ductile initiation at normal design minimum operating conditions, but some of the welds required passing a screen ing criterion to ensure they did not fall into Category 3). · Material Category 3 - Some vintage ERW-EFW and some vintage DSAW where they might fracture without any ductile tearing. Additionally, for each Material Category, there are three levels of analysis. · Level 1 is the simplest and provides guidelines if Charpy or toughness test data on the pipe line materials is not known. This level has greater conservatism than other levels where data exists due to comparatively higher uncertainty. · Level 2 is when the operator has Charpy data for the materials in their line. The Charpy data may only be at one temperature and may include different-sized Charpy specimens. Analysis of this data is needed to determine if there will be ductile initiation (i.e., the Charpy plateau energy is then used) rather than directly using the Charpy energy at the test temperature. · Level 3 is when the operator has more detailed fracture mechanics test data to pursue a more detailed fracture analysis for burst pressure predictions. This report presents the Level 1 procedure for each of the Material Categories, with a summary of some of the technical basis for how the Level 1 criterion was established. The Level 2 and 3 analyses are not presented in this report, other than some of the same information needed to sub stantiate the technical basis for the Level 1 values. There is a separate Level 2 and 3 report. Pragmatic Application of MegaRule RIN 1 - 192.712 Toughness Values ?

This review presents a comprehensive literature review of plasma-based technologies with potential applications in reducing emissions from pump and compressor stations in oil and gas pipeline infrastructure. The study focuses on lean burn natural gas engines commonly used in these stations and explores various plasma technology integration options.

The primary objective of Project NDE-4-22 is to develop simple guidelines based on industry and operator experience to ensure crack-related threats are addressed via inline inspection (ILI), when appropriate, across a variety of cracking threats and susceptible pipe types.

Siemens Energy proposes a methodology to monitor & predict emissions based on design and operational knowledge of the SGT-300-2S through chemical kinetics model of the turbine and advanced statistical regression analysis.

Having constructed, commissioned, and operated several CEMS, we may have a cost-effective alternative once PEMS is certified and deployed. The research completed illustrates promising results for next stages of this project.

The corresponding report PO743-22201-R01 Validation of Next Generation Predictive Emissions Monitoring System for Gas Turbines describes field trial demonstration and validation of a Gas Turbine Predictive Emissions Monitoring System (PEMS) using engine data from Siemens Energy SGT-300 gas turbine compressor drivers at SoCalGas Blythe Compressor Station, California, USA.

The advanced PEMS model results are compared with CEMS data taken from process analyzers measuring emissions in the gas turbine exhaust. After the necessary corrections on emissions for water content and oxygen content in the exhaust, the values for PEMS and CEMS show good agreement across a wide range of operating conditions. Areas where there is deviation between the values are investigated and potential improvements and modifications are suggested.

The use of PEMS shows promise as a robust and cost-effective alternative to analyzer based CEMS and can be used to provide additional diagnostic information. Recommendations for future work are presented.

Fatigue failure is a time-delayed failure that is one of the major threats to the pipeline integrity. For crack-like gouges in dents, the crack grows due to pressure cycling and eventually fails by fatigue. This work, which was funded by PRCI via Project MD-4-16, developed a viable engineering approach and a pragmatic fatigue model for predicting fatigue life of dents and gouges in pipelines. In particular, an equivalent stress method was developed with use of finite element analysis (FEA), and the crack driving force was determined based on the FEA results and the stress intensity factors (SIF) from API 579. The proposed fatigue model was evaluated with full-scale fatigue test data for line pipes containing dents and gouges, and then refined. The results showed that the refined fatigue model can predict adequate fatigue lives of dents and gouges in pipelines due to cyclic pressure.

This research effort focused on identifying equipment and processes that can be applied at compressor and pump stations to improve station operating efficiency, thereby reducing greenhouse gas (GHG) emissions. The project approach included a literature review and a PRCI member-company survey followed by evaluation and analysis and reporting tasks.

The digital twin used in this research is a mechanistic (or deterministic) computer model that represents the cathodic protection behavior of a pipeline network. The model is calibrated based on field data such that it mimics the real-world behavior of the pipeline. The objective of this research is to validate the accuracy of the digital twin model on three industry cases.

This webinar covers existing and emerging sensors that can be used to install retrofit flow measurement equipment to compressors and pumps, considering the unique equipment challenges.

X-ray Computed Tomography (XRCT) was initially developed and utilized in the medical industry to image the internal structure of the human body. X-ray imaging was conceived and realized at the turn of the 20th century and subsequently, XRCT, was conceived in the middle of the 20th century and its development continues today. Near the end of the 20th century industrial cone beam XRCT for applications such as dimensional metrology branched off, including its use for identifying and dimensioning flaws.

The current project scope was developed to address the specific gap between fabricated samples developed for full-scale test and real-world samples, and to provide further validation of the dent fatigue life assessment methodologies

Webinar presenting the details the methodologies used to collect and review crack failures, near misses and false positives, and how the available technologies are used in consideration of the CM-SRP pillars of crack (1) susceptibility, (2) inspection, (3) assessment and remediation, and (4) management.

The influence of upstream pipe roughness on the performance of multipath ultrasonic flow meters was examined through a set of experiments involving three different brands of ultrasonic flow meters. Tests were conducted with 16-inch meters with piping, having a wide variation in surface roughness values with and without a flow conditioner. These results, when combined with the earlier testing of 8-inch diameter meters, can be used to support changes in the practices currently recommended by industry standards.

Ground displacement along pipeline corridors has the potential to compromise pipeline integrity. The Appalachian Mountain region is almost entirely classed as high landslide susceptibility by the United States Geological Survey (USGS) and crossed by numerous transmission pipelines and gathering lines. In phase I of this research project, 3vGeomatics successfully demonstrated a proof of concept on the effectiveness, reliability, and precision of using L-band ( ) SAR satellites for InSAR displacement monitoring of vegetated areas.

Wellhead seals are a key component of reservoir and salt-cavern storage wells that function to seal the well from the external environment and separate stored fluids contained within the well. Loss of integrity of these seals or seal failures are a common occurrence in the storage industry. Practical guidelines on how to choose the proper sealing components and prevent seals from failing are generally lacking.

In this study, data related to wellhead sealing were compiled through a literature review, discussions with wellhead experts, and a survey distributed to Pipeline Research Council International (PRCI) members and others involved in the industry. Through the evaluation of this data, meaningful parameters involved in successful and failed seals were identified and best practice recommendations were provided on seal selection and wellhead design.

Understand the sources of conservatism, and how to improve the accuracy of, fatigue life estimation techniques for ERW or EFW pipes containing manufacturing process induced crack-like features.

Learn about an improved estimation method of remaining pipe fatigue life estimates that better agree with actual operational experience. This can reduce conservatism in engineering fatigue life estimates over currently used techniques.

Since fatigue life estimates are used to identify inspection intervals and assessing the life of features in a pipeline system, reducing unnecessary conservatism will avoid the cost of unnecessary inspections, pressure tests and repairs before fatigue life is expended.

The overall purpose of this project was to extend our understanding of the impact of human and organizational factors (HOF) on pipeline process safety incidents. Six pipeline incident reports were systematically analyzed using a two-phased approach developed in the Abnormal Situation Management (ASM®) Consortium research program. The first phase of the incident analysis approach used the TapRoot methodology to chart the event sequence, identify contributing factors, including organizational practice failures, and identifying root causes of the organizational practice failures. The second phase of the analysis characterized the organizational failures as Common Failure Modes based on the HCS Effective Operations Practices and the specific expression of the root causes in terms of Common Root Cause Manifestations based on the Dirty Dozen human factors taxonomy. The Dirty Dozen taxonomy of human factors was found to have the potential to provide a tractable root cause framework for human and organizational factors. Specific limitations of the Dirty Dozen taxonomy as a HOF framework are discussed.

Learning Outcomes:
· Understand the potential impact of human and organizational factors on pipeline process safety incidents.
· Understand the potential applicability of a human factors classification framework, the Dirty Dozen, developed in the aviation maintenance industry to the pipeline industry.

Expected Benefits:
· Increased awareness of the potential role and impact of human and organizational factors within the pipeline industry
· Catalyst for ideas on how to improve the incident reporting system within your organization to better characterize the impact of human and organizational factors.

Target Audience:
· Risk engineers
· Pipeline design engineers
· Pipeline construction, operations & maintenance management & personnel

PR-631-174506-R02 - Substandard Properties in Pipeline Fittings and Flanges

As a result of PRCI project IM-3E, a comprehensive guide was developed for the use of hydrostatic testing as an integrity management tool. While other industry research has focused on hydrostatic testing, none focused on the specific application of hydrostatic testing as a pipeline assessment tool to support integrity management plan requirements and objectives.

The scope of this work was to develop a document that provides the necessary guidance to pipeline operators on the appropriate use of hydrostatic testing within the integrity and risk management process.

The purpose of this research is to validate existing surface loading stress calculation methods and the key input parameters used to establish a degree of conservatism. This will enable greater confidence in recommendations based on the stress calculations and the type of load and soil. The results of the research allow for options in the interpretation of data for determining the proper mitigative activity during the construction of the pipeline.

Topics covered during the presentation will include:
· Effects of various loading over the pipeline with respect to varied soil conditions.

Expected Benefits/Learning Outcomes:
· Understanding and validation of available surface loading stress calculation models

Webinar/resentation on directing efforts towards reducing the environmental impact of operation through improving pipeline performance and addressing evolving regulatory requirements. To acheive this, , many different external leak detection technologies have been recently developed; however, it is challenging to test these systems with real hydrocarbon products.

The webinar describes the evaulation and performance of six external leak detection systems intended to identify the presence of hydrocarbon products on the surface of water.

This webinar presents the initial efforts of the Pipeline Research Council International, Inc. (PRCI) to evaluate technology solutions for pipeline monitoring and surveillance of the global energy infrastructure using Unmanned Aircraft Systems (UAS). Energy pipeline companies are considering a broad range of UAS applications to support upstream, midstream, and downstream operations with an emphasis on improving the reliability, integrity, and safety of pipeline assets.

The overall aim of the project is to identify the best practices in measurement system design and proving procedures in order to reduce measurement uncertainty. This is in recognition that improvements made to the calibration of flow meters would have a direct correlation in reducing system measurement uncertainty, improving overall pipeline balancing, and, amongst other benefits, reducing the minimum detection thresholds of leak detection systems.

This webinar presents the components and procedures that must be considered when conducting a pigging operation on a subsea pipeline system.

Note that the attached slides have been updated from the content presented during the webinar. "The vertical axis of the bar graph was mislabeled. For near-neutral SCC the vertical axis should have been "Proportion of excavations with SCC." So 76% of excavations on tape-coated pipelines found SCC, 32% of excavations on Asphalt found SCC and 23% of excavations on coal-tar coated lines found SCC (Fessler's data set 13). The numbers do not add to 100%, because they are not from the same populations. The difference between the way that near-neutral and high-pH SCC is displayed on this slide was due to the data provided to Fessler. Ray Fessler had data from a number of different sources and not all the data reported the occurrence of SCC in a consistent fashion."

The focus of this study was to determine the influence of subsurface engineered boundaries associated with the trench walls, and the presence of a water table, upon the leakage behavior of a range of hydrocarbon products. The project numerically modelled three products which were chosen to span a range of fluid types and viscosities. Laboratory simulations of leakage were carried out for the most viscous product in order to capture plume dispersion in semi-real time, and to allow numerical More...predictions to be assessed against experimental data._x000D_

Webinar presenting an overview of report PR-015-15608-W01 Sample Probe Insertion Depth Testing. Sample probes for natural gas sample collection and analysis must extend far enough into the pipeline to avoid contaminants at the pipe wall but must not be so long that there is a risk of flow induced resonant vibration and failure. PRCI has sponsored a project to determine the minimum probe depth for obtaining a representative single-phase gas sample in flows with small amounts of contaminants. Phase 2 of the project evaluated the effect of probe tip design and insertion length on the fidelity of gas samples from flows carrying small amounts of liquid hydrocarbons.
