Large Standoff Magnetometry (LSM) has emerged as an innovative and non-intrusive inspection technology, able to detect localised mechanical stresses in pipeline walls as well as inferring the amount of stress at these sites. LSM has traditionally been applied to identify pipeline threats which are both time dependent (i.e. corrosion) and time independent (i.e. dents). However, continued development of this technology has opened the door to even more beneficial applications such as uncovering stress associated with earthquakes, subsidence and mud slides. LSM’s unique ability to continuously log a pipeline’s depth of cover as well as noting changes in the pipe...
