Pipeline Current Mapping (PCM) is relatively new technology in locating faults and poor coating that is draining CP Currents, resulting in pipelines not adequately protected by its CP system. The PCM advantage over traditional DCVG Survey is mainly on its ability to conduct survey for pipelines buried under Concrete and Road Surface. It detects accurately the location of faults when conducted by highly trained operators. The PCM machine also comes with A-Frame which can be used to perform CIPS Survey.
