... Abstract Underground pipelines are inevitably installed in unstable geohazard areas associated with the possible development of significant ground deformations. Under ground movement, excessive strains can be generated in the pipe wall, which poses a threat to pipeline integrity. This study...

... Abstract Geohazards, consisting of geotechnical hazards where ground movements impact pipelines and hydrotechnical hazards where pipelines cross watercourses, can threaten pipeline integrity, causing leaks or ruptures. Given the vast geographies traversed by pipeline infrastructure, geohazard...

.... Transport system operators see a temporary role for themselves in solving this issue of imbalance. Gasunie will have developed a ‘hydrogen backbone’ by 2030, approximately 1200 km in length, of which 80% will consist of re-used natural gas pipelines with 36–48 inch diameters. Hydrogen pipeline networks can...

... Abstract The Probability of Exceedance (POE) methodology is used by pipeline operators to manage corrosion. It prioritizes anomalies identified by an in-line inspection (ILI) based on their likelihood of exceeding one or more failure thresholds. Two types of thresholds are commonly used: leak...

... Abstract Pipelines are an essential segment of infrastructure required to transport a variety of products to markets in our economies. The integrity and safe operation of those pipeline necessitates that pipeline operators have a thorough understanding of their pipeline systems...

... Abstract A technical review is presented of corrosion assessment models for determining the remaining strength of pipelines containing metal loss or corrosion defects. Initially, burst pressure prediction models for defect-free pipes, including strength and flow theory determined burst...

... Abstract Dent-gouges as a result of the mechanical damage have serious implications for the burst capacity of oil and gas pipelines. The burst capacity of pipelines containing dent-gouges is lower than that of the same plain dented pipelines without gouges and that of the same gouged pipelines...

... Abstract The technology to cost effectively design, construct, operate, and maintain ASTM A269 TP316L/TP316 stainless-steel pipelines for oilfield saltwater service and freshwater service was developed between 2002 and 2004. The first installations were austenitic pipe installed within...

...Abstract Abstract This paper presents a methodology to evaluate pipe stress induced by surface vehicle loading at uncased road crossings that are protected by mat or bridging. When vehicles cross an existing pipeline, additional circumferential and longitudinal pipe stresses induced by surface...

...Abstract Abstract The pipeline industry has long sought a unified near-neutral pH stress corrosion cracking (NNpHSCC) growth model, which fully describes salient growth elements. In response to this gap, the Pipeline Research Council International (PRCI) has funded a multi-year research project...

...Abstract Abstract In-service pipelines are often subjected to longitudinal forces and bending moments resulting from, for example, ground movement or formation of free spans in addition to internal pressures. In practice, there are some site-specific cases where corrosion anomalies interact...

... of Plausible Profiles (Psqr) corrosion assessment model that TC Energy (TCE) published in IPC 2018. Metal-loss corrosion continues to be a major integrity threat to oil and gas pipelines. Inline inspection (ILI) based corrosion management, where ILI measured anomalies are assessed and mitigated, has proven...

... that have failed historically in the pipeline industry. One of learnings from post-ILI failures due to corrosion in the industry is that corrosion morphology played a significant role. Previous model validations were mostly performed on simple single anomalies or simple clusters with few individual...

...Abstract Abstract The present paper deals with the subject of failure of deep-sea pipelines that have thickness metal-loss areas caused by corrosion and are subjected to high external hydrostatic pressure. An extensive research program was launched to observe failure modes, to examine existing...
