Pipelines are inextricably exposed to geohazards given that they are long linear facilities that encounter variable terrain and geologic conditions, including watercourses.
As such, reconnaissance, feasibility, and engineering design studies for new or existing pipelines need to include analyses that identify, characterize, and mitigate the potential long-term effects of geohazards on pipeline integrity. Also, there is a growing recognition that potential short-term effects of geohazards during construction, need to be addressed. Developing a pipeline project without considering geohazards early in the project cycle and mitigating them, as appropriate, is likely to lead to greater construction costs, contractor claims, schedule delays, and ultimately higher operational costs.
Under the auspices of the Pipeline Research Council International, Inc. (PRCI), a guidance document has been prepared to efficiently incorporate geohazard management guidance into a single volume addressing: i) the types of geohazards affecting pipelines, ii) the typical process used in practice to identify and characterize the geohazards throughout the various project stages, iii) the techniques used to mitigate the geohazards, and iv) the approaches and methods recommended to project teams of owners, operators, engineers, and contractors to successfully mitigate project risks. The guidance document is intended for a wide audience that includes technical and nontechnical managers at pipeline owning and operating companies, geoscience and engineering teams involved in studies and assessments of pipeline integrity hazards, and construction staff, regulators, lenders, and other stakeholders involved in executing pipeline projects. The presenters will review the PRCI guidance document and provide examples for its implementation.
