Pipeline Route Selection

Pipeline conceptual design and feasibility studies involve a route selection process.

GIS systems enable pipeline corridor options to be determined, utilising least cost path analysis. Surface analysis draws attention to a spatial context in which a least cost path is set.

Major considerations during pipeline route studies are inter-related with socio-economic, biophysical, geomorphology studies and cost engineering. Key factors are related to safety, environment and physiography.

Front-end engineering and design stages investigate pipeline route options in more detail. The route selection process will identify constraints, avoid undesirable areas, and maintain economic feasibility.

Select stage evaluates preliminary routes, providing information related to major crossings, population proximity, environmental considerations, terrain analysis, cost estimate and pipeline distance. Route refinement validates alternative options before an optimum route can be selected.

Surveying is required during field reconnaissance to confirm access, general topography, relief conditions, drainage and geotechnical implications.

Pipeline route alignment selection, addresses practical constructability cost issues, forming a critical part of the overall route selection process. Without this stage a well selected route corridor may later experience unexpected change, impacting construction schedule and cost.

The overall aim of the route selection process leads to a reduction of the overall cost of a pipeline system.
