Flowlines—pipelines or gas lines often cross hazardous environmental areas, from the point of view natural exposures such as landslides and earthquakes and from the point of view of third party influences such as vandalism or obstruction. These hazards can significantly change the original functioning of the flowline, leading to damaging, leakage and failure with serious economic and ecologic consequences. Furthermore, the operational conditions of the pipeline itself can induce additional wearing or even damage due to corrosion, erosion and fatigue. This chapter presents methods, techniques and their application to structural health monitoring and performance control.
