Deepwater’s RECAP device has been designed to collect rich subsea cathodic protection data.
Typical cathodic protection monitoring only requires infrequent measurements, sometimes more than a year apart. For special situations and complex equipment, however, it has been proven to be very useful to collect rich time-resolved CP data to help characterize the kinetics of a complicated CP system, or to troubleshoot intermittent depolarization or overprotection effects. The RECAP can be installed and retrieved in a variety of configurations, either topside (such as on a drilling stack or riser section), or subsea by ROV or diver. Several RECAPs have been deployed and have been continuously operating on drilling equipment since 2014.
