Internal Corrosion Direct Assessment Detection of Water

Over the last several years, The Office of Pipeline Safety attributes approximately 14 and 12% of natural gas and liquids transmission pipelines accidents, respectively, to internal corrosion. These incidents include some high profile failures involving fatalities, service/deliverability interruption, and environmental damage. Public safety concerns have provided the driving force for new regulations that require pipeline integrity assessments. There are currently three available pipeline assessment methodologies: (a) in-line inspection (ILI), (b) hydrostatic testing, and (c) direct assessment. Depending on the pipeline conditions the appropriate methodology can be used. Because of the uncertainties related to Internal Corrosion Direct Assessment (ICDA) and constraints making some pipelines unpiggable in the traditional sense, other technologies and alternative methods for pipeline inspection have been examined. In the present work, recent advances in computer technologies and wireless communications have been leveraged and combined in an attempt to address some of the challenges faced by the internal corrosion pipeline community.
