Internal corrosion monitoring provides data vital to the operation of high-capital-cost, subsea equipment such as pipelines, flowlines, manifolds and water injection equipment. Monitoring can be used to determine the efficacy of corrosion/erosion mitigation techniques and allows operation of subsea equipment to maximize useful equipment life and minimize maintenance. For the operation of subsea systems that utilized corrosion inhibitors, there is a particular need to monitor the inhibitor performance. Methods for remote monitoring of corrosion are rapidly developing as the pace of subsea developments increase. Subsea completions set a record in 1993, exceeding the previous all-time high by 18% and exceeding 1992 installations by 73%. This paper will review experiences with offshore corrosion monitoring, the currently installed subsea corrosion monitoring systems, discuss the use of intelligent pigs as monitoring tools, and review some of the technologies that could possibly be utilized in the future such as ion selective electrodes, radioactive tracers and spectroscopy.
