Our Cathodic Protection Services

CP Design & Installation

Complete system design and installation tailored to your assets, ensuring reliable, long‑term corrosion protection from day one.

CIS / CIPS
Surveys

Detailed pipeline surveys performed at close intervals to measure CP effectiveness and identify underprotected areas, coating issues, and interference.

ACVG, ACCA & DCVG Surveys

Advanced coating assessment methods used to locate, size, and prioritize coating defects before corrosion develops — supporting effective repair planning and ECDA programs.

Structure to Soil Surveys

Verification of CP system performance through accurate potential readings, helping confirm compliance and highlight areas needing attention.

Depth of Cover (DOC)

Measurement of pipeline depth, including critical areas like water crossings, to identify exposure risks and support regulatory requirements.

Regulatory Inspections

Completed alongside CP programs for efficiency,

Including

Mainline block valves (MLBV)
Right-of-way (ROW) condition assessments
Risers and above‑ground facilities
UAV (drone) inspections where applicable

CP Repairs & Maintenance

Issues identified during surveys are addressed immediately where possible, reducing follow-up work, downtime, and overall maintenance costs.

Digital
Reporting

Accurate, electronic data capture and reporting to support compliance, audits, and long-term integrity planning.

Close Interval Surveys
(CIS / CP CIPS)

A Close Interval Survey is a detailed cathodic protection check performed every few meters along the pipeline. It shows exactly how well the CP system is protecting the line.

Why It’s Important

CIS helps operators:

Spot low‑protection areas

Identify coating issues

Detect interference

Verify CP system performance

Support ECDA requirements

How It Works

Technicians collect continuous voltage readings along the pipeline route. These readings highlight where protection is strong, weak, or missing.

CIS helps pinpoint:

Under‑protected segments
Coating holidays
Stray current issues
Areas needing follow‑up or repair

It’s a fast, effective way to get a clear picture of pipeline CP health

Over‑the‑Line
Surveys

Coating Surveys – ACVG & ACCA: Our Over‑the‑Line Surveys provide a non‑intrusive way to assess pipeline coating condition and detect problems early.

Why It’s Important

Buried pipelines rely on coatings and cathodic protection to prevent corrosion. When coatings fail, corrosion can start quickly — often before it’s visible. These surveys help you:

Find coating defects early

Prioritize repairs

Improve pipeline reliability

Reduce long‑term maintenance costs

Support ECDA requirements

How It Works

ACVG (AC Voltage Gradient)
Uses an AC signal to locate coating defects along the pipeline route. Provides a quick and effective way to find areas where coating may be failing.

DCVG (DC Voltage Gradient)
Pinpoints coating defects and helps assess their severity by tracking current flow into the soil. Allows for more accurate repair targeting and prioritization.

ACCA (AC Current Attenuation)
Tracks how electrical current travels along the pipeline to identify changes that indicate coating breakdown or continuity issues. Useful for assessing overall coating condition over long distances.
