Integrity Management

Pipeline operator ultimate mission is to transport hydrocarbons with the highest standards of safety, reliability, efficiency and environmental responsibility. This mission cannot be achieved without assuring integrity of valves. Failure of a valve in a hydrocarbon network may cause a reduction in availability and reliability of the entire system...

Submarine pipelines are externally concrete coated to ensure vertical and lateral stability on seabed without excessive movement. During operation and especially towards late life and beyond, concrete may be lost which must be compensated in the form of stabilization weights. The weight requirements are typically calculated based on concrete...

Pipeline operators rely on ILI and NDE to ensure system integrity, but these methods face challenges when detecting and sizing off-axis cracking. What if NDE suggests a systematic bias in ILI results? Can this data still support Integrity Management Programs (IMP)? In a Phase 1 case study, NDT Global and Phillips 66 developed a systematic method to...

In contrast to traditional oil industries, the oil sands sector experiences severe wear-related problems due to the inherently abrasive and corrosive nature of the mined oil sands. This wear affects the mining and extraction processes, causing rapid pipe wall loss in carbon steel slurry pipelines over a relatively short period. To extend service...

Magnetic Flux Leakage (MFL) technology has been widely used for pipeline inspection due to its reliability in detecting metal loss. However, unidirectional axial (MFL-A) and circumferential (MFL-C) tools have inherent limitations in detecting and sizing complex corrosion anomalies. These limitations often result in conservative reporting, increased...

Efficient hydrocarbon transportation depends on extensive pipeline networks requiring regular inspections for safety and efficiency. Deadlegs, parts of the system prone to corrosion, pose significant challenges. Traditional manual ultrasonic testing lacks the accuracy needed for effective corrosion assessment. Permanently installed ultrasonic...

Pipeline inspection for cracks and corrosion through intelligent inline tools relies on ultrasonic probes, demanding a 100% first-run success rate to minimize costs. These probes face harsh environmental conditions within pipelines, necessitating utmost stability for optimal functionality. Material selection and rigorous testing during development...

Pipeline Integrity Management Systems (PIMS) have significantly improved the safety of pipelines in Europe and the United States. New technologies such as artificial intelligence (AI) and modern Geographic Information System (GIS) visualization can and will elevate pipeline integrity to a new level. However, challenges for pipeline integrity have...

Pipelines are typically designed using different practices and codes than in-plant piping. While Risk-based Inspection (RBI) quantitative methodologies have evolved and been applied for in-plant piping, e.g. API RP 581, limited methodology framework has been specified and widely used for pipelines, in a similar approach. Alternatively, for...

This work is centered on the integration of different Leak Detection Technologies into a single platform for a better management of Pipeline Integrity Monitoring issues. Leak detection methods covered in this paper are based on Advanced-Negative Pressure Wave, Mass-Balance, Acoustic-Noise, and other predictive techniques based on data processing...

Seawater Injection is a well-known technique which helps in supporting oil recovery cost effectively by injecting treated seawater at high pressure in the reservoir. This injected water is delivered through water injection wells placed along the periphery of the entire oilfield reservoir. The water is transported to the wells by a vast high...

In the Oil & Gas industry, pipelines often handle fluids which may be hazardous, flammable and/or toxic. Any interruption to operations for unplanned maintenance or operation activities is considered a risk of release of harmful energy or materials into the work area. Proper isolation of equipment is selected considering the nature of work activity...

In PETRONAS, there are on-going initiatives at petrochemical plants, gas processing plants, Upstream’s well engineering and retail business in pursuing the digitilisation in line with the Industrial Revolution (IR) 4. The aim of the initiatives is basically to improve the efficiency of critica l processes thus at the end will reduce overall cost...

One of the most severe accidents which could occur in a gas transmission pipeline involves the linepipe wall failure and subsequent fracture initiation, which may evolve in a long running fracture propagation if the material toughness properties are not adequate. The most acknowledged approach for ductile fracture propagation assessment is the...

Leak detection, TPI (Third Party Interference) and asset integrity are crucial topics in pipeline monitoring, although they often require costly procedures and systems. In order to support the pipeline integrity management, Eni S.p.A, in collaboration with Solares JV, developed the e-vpms® (Eni Vibro-acoustic Pipeline Monitoring System). This...
