C-FER Technologies and OneBridge Solutions Partner to Help Operators Make Data-informed Pipeline Integrity Decisions

C-FER Technologies and OneBridge have partnered to provide pipeline integrity engineers with an automated probabilistic risk assessment solution for pipelines. This technology sharing agreement will integrate C-FER’s risk models into OneBridge’s Cognitive Integrity Management (CIM) Software-as-a-service (“SaaS”) solution. Leveraging C-FER Risk Models with OneBridge’s Cognitive Integrity Management System OneBridge’s CIM clients will now have the option to access C-FER’s risk models in OneBridge’s data collection systems. The integrated system provides integrity engineers with the ability to roll up, or drill down into, the information for specific pipeline segments and determine the probability of failure. [...]

How to Establish a Detection Threshold for Acoustic-based External Leak Detection

A number of fibre optic cable-based systems that employ distributed acoustic sensing (DAS) were analyzed to characterize their leak detection sensitivity. The sensitivity analysis involved (1) identifying a suitable release parameter capable of providing a defensible basis for defining detection sensitivity and (2) the application of regression analysis to characterize detection sensitivity as a function of the chosen release parameter. The paper—Establishing a Detection Threshold for Acoustic-based External Leak Detection Systems—describes the analysis approach developed to quantitatively determine leak detection sensitivity for various DAS technologies and deployment positions during two full-scale tests. The release [...]

Using a Bayesian Approach for Crack Depth Measurements

A Bayesian approach has been applied to inline inspection (ILI) and non-destructive examination (NDE) field measurement data to increase confidence in estimated feature depths. Multiple crack depth measurements were used to improve the characterization of ILI sizing error bias and to update the maximum depth distribution of individual crack features. The paper—A Bayesian Approach for Effective Use of Multiple Measurements of Crack Depths—describes the application of Bayesian methodology to three datasets, two of which collected over a series of Pipeline Research Council International (PRCI) projects. The results show that Bayesian updating, when compared to [...]

Using a Limit States Design Approach for Assessing Corrosion and Cracks

C-FER has developed a limit states design (LSD) approach to assess corrosion and crack features in onshore transmission pipelines. The LSD approach is a simplified form of the reliability-based approach that reduces the latter to a set of deterministic checks. It achieves the same benefits on an approximate basis and is easy to apply. The paper—Demonstration of a Limit States Design Method for Assessment of Corrosion and Crack Features—describes the application of the LSD approach to two low vapour pressure liquid pipelines (one with corrosion and one with crack features) and provides a comparison [...]

Evaluating On-water Leak Detection Technology

A comprehensive research project through the Pipeline Research Council International (under contracts PR-244-173902 and PR-244-193900) was completed to assess the abilities of various on-water external leak detection technologies to identify the presence of liquid hydrocarbon products on the surface of water in a controlled laboratory environment. The first phase of the project evaluated the performance of six technologies using eight test fluids in an idealized freshwater environment under ambient conditions. The second phase investigated the effect of freezing conditions on the performance of these technologies. The paper—On-water Liquid Leak Detection Technology Evaluation—describes the test [...]

How to Assess Spill Volumes from Hazardous Liquid Pipelines

Using publicly available data from PHMSA, an analysis of product release events associated with the onshore US hazardous liquid pipeline network was conducted to understand what historical data indicates in terms of actual release volumes and how they are affected by key pipeline attributes. As a result of this analysis, a simple model to determine release volume averages and their range based on the pipe diameter and mode of failure was developed. The paper— Analysis of Hazardous Liquid Pipeline Spill Volumes —describes the analysis of selected data in regards to: Release volume, Pipe diameter, [...]

Standard Reliability-based Approach vs Bayesian Network Approach for Integrity Management

A feasibility study was conducted to identify an approach to estimate the probability of leak due to internal stress corrosion cracking (iSCC) that uses previous investigations and handles data gaps. A standard reliability-based approach and a Bayesian Network approach were compared based on: Effective use of data; Flexibility of framework; and Ability to improve outcomes based on additional information. The paper— Comparison of Feasibility of a Standard Reliability-based Approach and A Bayesian Network Approach for Integrity Management of a Northern Canadian Liquids Pipeline —describes the: Standard reliability-based approach; Bayesian Network approach; Criteria for the [...]
