How to perform quantitative risk analysis for transmission pipelines
Friday, September 21st, 2018
Framework for the Quantitative Risk Analysis Process

Quantitative risk analyses are used in the pipeline industry to identify high-risk locations and main contributing threats; to evaluate risk against an acceptance criterion; to evaluate changes in risk over time; to guide integrity management decisions; and to demonstrate regulatory compliance.

How to improve corrosion assessment using reliability-based criteria
Thursday, September 20th, 2018
Illustration of the probability of failure as a function of time for a corrosion feature

Corrosion assessment criteria in current standards for onshore transmission pipelines rely on safety factors that are experience-based, with their implication on the risk or safety level associated with the pipeline unknown.

Working as part of a joint industry project, we have developed reliability-based corrosion assessment criteria in a deterministic format that are calibrated to achieve a specified safety level. The main features of the criteria are:

How to apply limit states design rules for geotechnical loads
Wednesday, September 19th, 2018
Using a structural reliability-based approach to develop the strain demand and strain capacity parameters

A limit states design approach for onshore pipelines has been developed with reliability-based design rules for geotechnical loads. In consideration of the modelling complexity of the soil movement mechanisms and pipe-soil interaction, and to allow for flexibility to incorporate future model developments, the design rule formation is directly based on the distribution parameters of the strain demand and capacity of the pipeline.

Does feature length growth affect predicted burst pressure in pipelines?

Effect of defect length growth on probability and mode of pipeline failure

The pipeline industry has established various methodologies to estimate corrosion growth in pipelines. However, growth of corrosion feature length is inconsistently addressed in these methods.

We worked with Enbridge Pipelines to review these methodologies and determine the impact of feature length on corrosion burst pressure predictions.

How to analyze angled cracks in spirally welded pipelines
Monday, September 17th, 2018
Example of Spiral Pipe Manufacturing

Spirally welded pipelines (extensively used in liquid transmission pipeline systems) may contain manufacturing anomalies that are susceptible to fatigue growth. To account for the angle of these cracks with respect to the longitudinal pipe axis, modifications to inputs of crack assessment models are required.

Using the widely-used pipeline assessment model CorLAS®, we worked with Enbridge Pipelines to investigate two input modifications:

How to apply limit states design checks to geotechnical loads
Monday, September 17th, 2018
Soil Movement Geometry and Orientation

A limit states design approach has been developed for geotechnical loads using a strain-based design format. This approach addresses the high level of uncertainty associated with the loading processed, which has limited the availability of design guidance in the past.

Working as part of a joint industry project, we have carried out a project to calibrate risk-consistent limit states checks that can be used for a range of strain demand and capacity distributions applicable to geotechnical loads.

The project:

Does reliability-based corrosion assessment criteria reduce risk?
Friday, September 14th, 2018
Example of the Relationship between the Safety Factor and Feature Density

Corrosion mitigation for pipelines, vintage pipelines in particular, has a significant effect on the industry’s management systems and related costs. To help optimize the corrosion management process, deterministic reliability-based corrosion assessment criteria have been developed for onshore pipelines as part of a joint industry project.
