Cathodic protection design and commissioning for pipelines
What CP helps you achieve
- Prevents external corrosion before it escalates by providing controlled electrical protection to exposed steel surfaces.
- Extends asset life and reliability by maintaining protection levels over time through monitoring and periodic checks.
- Supports compliance and audit readiness with documented CP performance, surveys, and maintenance records.
Typical applications
- Buried/onshore pipelines and pipeline crossings (including landfalls and immersed sections such as river/lake crossings).
- Offshore pipelines, flowlines, risers, and related pipeline elements in submerged service environments.
- Underground or submerged metallic piping systems where external corrosion control is required and sustained.
CP system options
- Galvanic (sacrificial anode) systems for many submerged/soil environments where passive, distributed protection fits the design life.
- Impressed Current CP (ICCP) systems where higher current demand, long circuits, or operating conditions require controlled current output.
Our Cathodic Protection Services
1. Engineering & implementation support
- Pre‑installation surveys and feasibility: We collect key site inputs (soil/water environment, coating condition, continuity, interference risks) to design CP correctly.
- CP system design & specification: We design CP systems with defined design life, performance criteria, and equipment selection aligned to recognized guidance for pipeline CP programs.
- Installation supervision & quality checks: We support correct installation practices for anodes, cabling, test stations, isolation, and associated CP hardware so performance remains stable.
- Commissioning and performance verification: We verify CP functionality after energization and establish baseline data for ongoing integrity tracking.
2. Monitoring, surveys & optimization
- Routine monitoring & data trending: We monitor protection performance and identify deviations early so corrective actions remain timely.
- Interference and external corrosion control support: We help manage conditions that can reduce CP effectiveness and guide mitigation where required, using accepted practices for underground/submerged piping systems.
- Maintenance planning & documentation: We maintain records and reporting, so your CP program stays traceable and audit ready.
What you receive
- CP design package (basis of design, calculations/criteria, equipment specs)
- Commissioning report with baseline performance data
- Monitoring & survey reports with recommendations and action priorities
- Maintenance plan + documentation set to support lifecycle corrosion control
