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.
Key design points

Visual status indicator
An informational LED on the logger's face blinks to visually indicate status.

Fastens via web clamp
The logger mounts on a clamp that's electrically connected to the structure. It’s ideal for equipment that returns to the surface periodically, such as drilling equipment.

Retrieval options
The RECAP™ can be brought topside and interrogated using the convenient USB connection. There's even an optional ROV retrieval interface available.
