Abstract: One third of the 540,000 km (335,000 miles) of pipelines worldwide are considered unpiggable because of access and valve restrictions, multi-diameter designs, impassable fittings and a myriad of other configuration issues. Notwithstanding these obstacles, many countries have emerging regulations that will require these pipelines to be inspected on a continuing basis. Currently, there is a significant demand for inspecting unpiggable pipelines, particularly in sensitive High Consequence Areas (HCAs) where consequential risk to the public or the environment is high. In the petroleum transmission and distribution sector over 12 billion1 is spent each year on corrosion. Investment in technology is imperative to control costs as the pipeline infrastructure continues to age. The development of the technology discussed in this paper is an excellent example of using technology to resolve difficult pipeline integrity challenges. With that in mind the authors wish to add that the Department of Transportation provided funding assistance for the development technology discussed in this paper.
