Abstract: A method of inspecting a length of pipe having a pipe wall and a nominal inner diameter, comprising providing an inspection pig configured for passing along the length of pipe, wherein the inspection pig is provided with a substantially circumferential inside-out capacitance tomography sensor arrangement having a diameter smaller than the nominal inner diameter; passing the inspection pig along the length of pipe thereby defining an annular space between the sensor arrangement and the pipe wall; conducting measurements using the sensor arrangement at a plurality of locations along the length of pipe, and deriving, for each of the plurality of locations, information about an interface surrounding the inspection pig from the measurements. Further provided is an inspection pig for inspecting a length of pipe, wherein the inspection pig is provided with an inside-out capacitance tomography sensor arrangement.
