]]> This Joint Industry Project (JIP) was initiated to address several recent pipeline failures that have occurred at girth welds in pipelines that were constructed using API 5L X70 line pipe, and field welded using API 1104 qualified welding procedures. These failures occurred in pipelines that were designed using conventional stress-based design. Some of these failures occurred during hydrotest or shortly after the pipeline entered service. Since this project commenced, additional failures have occurred further highlighting the necessity to address this problem. Clearly something needs to change in order to eliminate future pipeline failures with similar attributes…

]]> INTRODUCTION

The Pipeline and Hazardous Materials Safety Administration (PHMSA) has recently proposed a “Draft Integrity Verification Process” (IVP), part of which requires hydrostatic testing to establish the maximum allowable operating pressure (MAOP) and verity the integrity of pipelines that were either not tested after construction or for which such tests cannot be reliably confirmed. This study reviews pipeline incident data and fracture mechanics models that may support limited exemptions or alternative measures from the requirement for hydrostatic pressure testing to 1.25 times the MAOP in order to assure the stability of pipe manufacturing or construction related features. This study was performed at the joint request of the Interstate Natural Gas Association of American (INGAA) and the American Gas Association (AGA).

]]> The intent of this white paper is to provide INGAA members with a framework of recommendations for the next evolution of integrity management based on the management system elements in ASME B31.8, B31.8S and current regulations. The recommendations included in this paper are flexible by design and draw upon the experience of industries that have a risk profile that includes high consequence, low probability events. Operators that have a basic management system built around the B31.8S elements will be able to use this white paper to chart a course to move to the next level, recognizing that any management system must be fit for purpose and fit for the company’s culture.

Programs related to Integrity Management (IMP), Health Safety and Environment (HSE) (including Emergency Management/Incident Mitigation Management), Control Room Management, and Quality Management (QMS) form barriers; layers of defense to incidents. Research indicates that organizational accidents rarely occur due to the breakdown of a single program; usually, it is the alignment of weaknesses across multiple programs that enables compound conditions to result in a high consequence event. Work to make these programs more effective, comprehensive, systematic and integrated is work to reduce the risk of organizational accidents.

This paper includes a brief background on management systems, the principles of making them work, a framework for measurement and the concept of a maturity model intended to allow operators to identify where they are in the evolution of the management system approach and to make choices where they want to go over the next several years.

]]> One key aspect of any pipeline integrity management and verification program is to identify threats to a pipeline’s integrity. One threat that is receiving more attention in the gas pipeline industry is cyclic pressure induced fatigue. As with other integrity threats, the risk of fatigue should be understood and characterized correctly by a pipeline operator in order to prioritize responses and minimize the chance of fatigue impacting the integrity of a system. As part of understanding and characterizing the risk associated with cyclic fatigue a pipeline operator must be able to understand what scenarios (i.e. operating conditions, pressure levels, pipeline features) may lead to fatigue and what scenarios can reasonably be expected to pose no fatigue risk.

Although a variety of cyclic fatigue loading can occur in a pipeline system, (i.e. mechanical vibration, thermal loads, etc.), the following report is focused on internal cyclic pressure induced fatigue, where the internal pressure fluctuations experienced by a pipeline can result in fatigue crack initiation and propagation, under certain circumstances.

]]> The purpose of this report is to show the range and results of methane studies in the public literature. The results and findings in the studies referenced in this report vary significantly. Scientific methods and uncertainty principles need to be employed rigorously in evaluating these studies. Given the significant variation in results, we caution against the use of any single study as the basis for policy choices that have potential implications for U.S. energy/environmental policy and the U.S. economy.
