Abstract

A detection apparatus arranged to detect defects within a flexible pipe body. The detection apparatus comprises an electrical power supply and a first meter. The electrical power supply is arranged to couple between, and to supply current to, first and second electrically conductive members extending at least partially along the length of a flexible pipe body and electrically isolated from one another except for being electrically connected at a point remote from the power supply. The first meter is arranged to detect variation between the current flowing in each electrically conductive member. Detected variation is indicative of a pipe body defect causing an Earth fault along one of the electrically conductive members. A corresponding method, a pipeline apparatus including the detection apparatus and a method of forming the pipeline apparatus are also disclosed.
