Abstract

The introduction of subsea pipelines in the Arctic Ocean has provided an opportunity to collect accurate steady state polarization data in this environment. In order to record this data, a cathodic protection monitoring system was designed and installed on a recently built pipeline in the Beafort Sea. The system includes sensors to measure a range of parameters including anode current output, pipeline potential, current density and temperature. The layout, design approach, and results are discussed.
