Design and Implementation of an Offshore Remote Monitoring System for Corrosion, Coating and Cathodic Protection Performance

Remote monitoring of corrosion and cathodic protection using various methods have matured for decades with the onshore pipeline industry. With increasing activity offshore, and the highly corrosive and inaccessible environment taken into consideration, it is only natural that remote monitoring technology will find its way into this field. Offshore structures of steel are protected against corrosion with protective coatings and/or cathodic protection.

A remote monitoring system for corrosion, cathodic protection and coating performance has been designed. The system comprises electrical resistance probes for corrosion measurements that also measure cathodic protection parameters such as potentials, currents, spread resistance and coating impedance at specific sites of interest, which facilitates an in depth and continuous analysis and evaluation of the corrosion protection systems installed on a structure. The system is ideal for offshore wind power (monopiles, jackets or floaters) since these structures are un-manned, making routine inspections difficult and expensive. But the system can easily be adapted for other applications where remote monitoring is desired. In addition, the system can also be fitted with auxiliary sensors such as depth-, oxygen-, pH- or other sensors.
