25.11.4 Field monitoring and testing of
pipeline performance

Field monitoring of the performance of pipelines, or soil mass in the vicinity
of pipelines, has the potential to play an important role with respect to
several key aspects of pipeline geotechnical engineering including, but not
limited to the following:

• assessment of potential imminent pipeline concerns;
• identifi cation of pipeline performance in areas of less understood,
varying, soil and groundwater conditions;

• development of an understanding of fi eld variations that are not neces-

sarily captured in general design works using existing guidelines;
