This paper will explore the process of conducting asset integrity management systems and the potential use for the existing facility data to analyze integrity status and predict any breach of integrity that would cause a direct major incident. In the dawn of the 4th industrial revolution and in the age of automation and artificial intelligence, asset integrity management systems are being integrated into a more sophisticated process of verification. Programs are being used to collect necessary risk-based data from inspection, maintenance programs and operational checklists in order to rationalize the integrity status and alert proponents of possible breach of integrity. These systems are more efficient than humans in predicting possible failures based on collective data from several critical elements from a facility and calculate the probability of failure based on the current integrity status. It is possible to optimize such systems to eliminate the human error factor and optimize inspection, maintenance and operation programs to better manage asset integrity. The result would be a software that would provide an overview of the plant’s integrity status and provide early alerts of any incoming incident event which allows the facility’s management to act accordingly and direct resources for effective prevention and mitigation.

Metallurgical Analysis of 30-Inch Pipe Containing an Internal Crack

Product Number: 51324-20700-SG

Pipeline defects are routinely found in the oil and gas industry. Most often they are minor, and do not affect the integrity and safety of the pipeline. However, in some cases, identifying and repairing critical defects is mandated to ensure long term integrity, which also entails choosing an appropriate repair technique. In this case study, we present a metallurgical examination of a 1949-vintage Grade X52 pipe containing an internal crack that was first identified at a client site. Laboratory examination confirmed that the feature was a pre-existing imperfection or defect, which had been weld repaired around the time of manufacturing or installation. Grinding marks and a distinct weld zone with three welding passes were observed in the region surrounding the crack. Scanning electron microscope (SEM) fractography of the crack surface indicated the presence of columnar grains close to the inside surface that are typical of a carbon steel weld. Energy dispersive x-ray spectroscopy (EDS) analysis indicated that the corrosion products consisted of iron

PHMSA Gas Pipeline Mega Rule

Product Number: 51324-20895-SG

Author: Sasan M Hosein

Publication Date: 2024

$40.00

The Pipeline and Hazardous Materials Safety Administration (“PHMSA”) recently released the final rule known as the “Mega Rule” which includes a set of regulations designed to improve pipeline safety by reducing the frequency of pipeline failures. The intent of the rule is to address lessons learned following the Pacific Gas and Electric Company rupture and release in San Bruno, California, in September 2010. On September 9, 2010, a natural gas pipeline owned by Pacific Gas & Electric (PG&E) exploded in San Bruno, CA. creating a fire that killed eight people, destroyed more than 100 homes and cost $2.8 billion. An investigation by the National Transportation Safety Board (NTSB) found that PG&E had a faulty integrity management (IM) system that failed to detect a defective section of the pipeline resulting in the devastating explosion. The PG&E incident spurred action from the Pipeline and Hazardous Materials Safety Administration (PHMSA) to revise the existing Federal Pipeline Safety Regulations (FPSR) to improve the safety of onshore gas transmission pipelines. These revisions are known as the Mega Rule. This final rule responds to the incident by extending existing design, operational and maintenance, and reporting requirements under the Federal Pipeline Safety Regulations to onshore natural gas transmission pipelines and gathering pipelines in rural areas. The Mega Rule is a sweeping set of regulations comprised of three parts: • Part 1 focuses on the safety of gas transmission pipelines. • Part 2 introduces new guidelines about IM, updated requirements for high consequence areas (HCAs) and expectations for operators following extreme weather events and natural disasters. • Part 3 expands certain safety requirements to all onshore gas gathering pipelines.

Upstream Assets Integrity Management

Product Number: MPWT19-15264

Author: H. Seshadhri Srinivasan

Publication Date: 2019

$0.00

Upstream oil production assets, including oil production pipeline network and gas oil water separation facilities, play a dominant role in sustaining production targets to meet customer requirements. Corrosion management of such assets encompasses various phases, such as design, construction, operation, and decommissioning. Proper engineering design and sound construction practices combined with effective monitoring are essential to manage and maintain the corrosion of these assets within acceptable limits. Some of the considerations taken into account during design include: safety, environment, pressure, temperature, material availability, delivery time, and cost. Operating these assets outside of the design boundaries could influence the corrosion process, significantly impacting integrity. Close monitoring of operating parameters, along with identifying the corrosion by employing appropriate inspection techniques, and implementing timely corrective measures, are of paramount importance to preserving the integrity of these critical assets, which otherwise could lead to safety and environmental issues. This paper highlights three case studies involving the importance of cathodic protection monitoring, and failure analysis of an oil pipeline, along with corrosion inhibitor optimization efforts carried out to ensure asset integrity.
