Abstract
Embodiments of the present disclosure provide devices, systems and methods for monitoring anti-corrosion efforts including the efficacy of cathodic protection systems. Embodiments of the present disclosure provide devices, systems and methods for remote cell cathodic protection (CP) survey data acquisition to sense, display, and record CP survey voltage potential measurements as well as global positioning system and navigation data. Embodiments of the present disclosure provide improvements in terms reduced noise and improved signal quality through the use of copper conductors that connect electrochemical reference cells (i.e., electrodes) to measuring apparatus. Further, improved signal detection is provided by embodiments including reference electrodes that may be placed further (e.g., up to 1000 feet) from a surface vessel than are found in conventional system. Disclosed embodiments also provide highly precise spatial mapping of CP potentials (e.g., to within 0.5 mm spatial resolution in 1000 feet of depth).
