PARSC 013 –Analysis of Pipeline Exposure Data and Scoping Review of Exposure Scenarios FEATURED


On behalf of the Pipeline Abandonment Research Steering Committee (PARSC), PTAC wishes to retain the services of a research organization or consulting firm (the Contractor) to provide the services described in this document.


Pipeline abandonment refers to the permanent removal from service of a pipeline. Depending on a number of factors, sections of pipeline may be abandoned in place or removed.

Geotechnical hazards may lead to the exposure of abandoned pipeline. The consequences of exposure include interference with land-use, and acceleration of degradation the coating and the pipe. Examples of geotechnical hazards that may lead to exposure include hydro technical hazards generally associated with channelized flow of streams and rivers, surface erosion associated with rainfall and slopes, failure of buoyancy control measures, and frost heave.

This issue was reviewed in the prior DNV Scoping Study found on the website of the National Energy Board ( Applicants are expected to read relevant sections of the Study, as this project was informed by it and information is not repeated herein.

PARSC published in 2014 the report entitled “Frost Heave Effects on Pipeline Exposure Rates" (

Project Objective

The objective of this study is to lead to a greater understanding of the potential causes or scenarios that would lead to the exposure of abandoned buried pipelines.

Please refer to the attachments section of this RFP notice for full descriptions of the RFP and RFP Outline.
