Polatrak® Cathodic Protection Monitoring
Corrosion testing with permanent
monitoring systems
An introduction
Our Polatrak brand cathodic protection monitoring instruments and CP probes form the most comprehensive collection of monitoring equipment available in the market. Consistently praised in the industry for rugged build-quality and intelligent design, Polatrak systems provide asset managers with every dimension of data possible, allowing them to feel confident about the cathodic protection systems they have in place, and letting them know when a system has fulfilled its design life.
Polatrak monitoring systems are comprised of three main components:
1. Fixed instruments for collecting cathodic protection data subsea.
2. Readouts and panels topside or subsea for interrogating the instruments.
3. Interchangeable attachments and modifiers designed to make Polatrak systems compatible with any asset, new or in-service.
Fixed Instruments include: DR-2 Permanent Dual Reference Electrode, MA-1 Monitored Anode, DR-2 CD Polarization Monitor, V-String Reference Electrode. Readouts include: SunStation Subsea Monitor, Topside Monitoring Panels
Polatrak active installations can be found on any type of asset: FPSO's - hulls, tanks, moorings, risers & turrets, SPAR, TLP or other FPS systems, Platforms & compliant towers, subsea production equipment, MODU's, docks and harbors, offshore pipelines & risers, and process vessel interiors.

Polatrak Monitoring Instruments
SunStation Subsea Readout
A permanent light-powered subsea readout, activated by the light of an ROV. Designed for deep water, it can be attached to a variety of corrosion monitoring instruments. More
V-String Reference Electrode
A general purpose zinc reference electrode, which can be installed at any critical corrosion monitoring area. It can also be retrofitted, attached to a RetroClamp™ via ROV. More
DR-2 Dual Reference Cell
Dual permanent reference electrodes (Zn and Ag/AgCl) housed in a single instrument; welded-on for new construction or clamped by ROV or retrofits with a RetroClamp. More
DR-2 CD Polarization Monitor
A standard DR-2 reference cell fitted with a current density monitor (metal "fin"). This combination allows the operator to calculate polarization on the monitored structure. More
MA-1 Monitored Anode
A standard aluminum anode fitted with a monitor that allows the operator to test anode current output and overall depletion rates. It can be applied to platform or pipeline anodes. More
SmartClamp Test Station
Deepwater’s standard RetroClamp fitted with a V-String zinc reference electrode and a SunStation monitor to create a stand-alone pipeline CP test station subsea. More
Topside Monitoring Panels
For monitoring of fixed structures, where Subsea interrogation is unnecessary, topside panels can be customized to for any combination of monitoring instruments. More
