Optimizing Cathodic Protection Survey Using Non-contact Sensors
location, depth, environmental conditions, and the specific requirements of the maintenance plan.The most common form of measuring CP systems is known simply as ‘stabbing’. It involves the use of a contact probe (a.k.a., ‘CP stabber’) making direct contact measurement to the steel structure and the anodes, either by divers or ROVs. The probe typically consists of one or two silver/silver chloride (Ag/AgCL) reference electrodes. A voltmeter measures the potential difference between the structure and the reference electrode.The CP level of structures can be measured with conventional
