Way Ahead In Corrosion Control

Deep C Meter

Polatrak® cathodic protection survey system for ROVs

DeepCMeter_ROV2_WEB.jpg

The Deep C Meter™ is the premier ROV cathodic-protection survey system for use in deep water.

The Polatrak® Deep C Meter™ is designed for rugged service on a work-class ROV. The unit can integrate fully with ROV systems for power and data transfer, or it can operate as a visual inspection unit, with no interface with the ROV umbilical. The unit is rated to 3000 m depths, and each unit is built and tested in Deepwater's Houston manufacturing facility.

Pipeline survey modes

STAB SURVEY

The stab survey method records the actual steel potential with periodic stabs every 1 - 3 km. The potential between stabs can be accurately calculated with pipeline attenuation modeling. Deep C Meter ™ software in Stab Survey mode records events and exports a completed survey for the engineers to model.

REMOTE ELECTRODE SURVEY

The remote electrode method calibrates a remote reading with periodic stabs of bare steel along the pipeline.  The data is then aligned in post processing.  Not as accurate as a stab survey, but required in some regions. Deep C Meter™ software in Remote mode outputs stab events and the complete set of readings from the proximity electrode for processing.
