In this course, you'll learn about pipeline crossings and the various techniques used to minimize the risk of damages at line intersections.
There are two distinct definitions to pipeline crossing. In the first instance, a pipeline crossing is where the pipeline intersects with another obstacle which can affect the course or integrity of it. Roads, railroads, waterways, other pipelines, utility corridors containing cable and power lines are examples of items which can affect the course or the integrity of a pipeline.
In the second instance, a pipeline crossing is where an activity is being performed in the vicinity of the pipeline, which could potentially disturb or damage the pipeline. Special construction techniques must be used to minimize the risk of damage to either installation. Procedures used to locate the buried installations is called line location.
