The increasing use of remotely operated vehicles, (ROVs), in the inspection of deep water offshore platforms, has led to the development of a new computerized cathodic protection survey system. This new system has been specifically designed to gather continuous potential and current density data without any significant increase in offshore inspection time. The system has been employed on a number of structures in the Gulf of Mexico throughout the 1985 offshore season. This paper describes the survey technique and demonstrates how computer technology has facilitated rapid collection of comprehensive cathodic protection system performance data in 300' + (92m.) water depths.
