CP-Probe
Electrochemical potential probe for subsea cathodic protection inspection
The CP-Probe is BMPTECH's subsea electrochemical potential measurement system, developed for cathodic protection inspection integrated with ROVs.
The CP-Probe, internally designated CPEL METER model BCP-CPEL-001, is a subsea electrochemical potential measurement system developed and manufactured by BMPTECH for cathodic protection (CP) inspection of submerged structures. The package combines a remote voltmeter, graphic display, charger and interchangeable contact or proximity probe tips, covering different measurement geometries in the field. The reading stage uses a 24-bit analog-to-digital converter and high-stability components, delivering up to 6 digits of resolution for reliable protection potential surveys. Its compact form factor is designed for integration into small ROVs, and the electronics engineering, firmware and manufacturing are developed in-house at BMPTECH, enabling calibration, maintenance and adaptation of the unit throughout its full life cycle. A 6800 mAh lithium battery provides up to 36 hours of continuous operation, and data is transmitted to the surface over RS232, RS422 or RS485 for integration with broader inspection systems.
Applications
- Cathodic protection inspection of pipelines, risers and submerged structures
