Cathodic Protection Services
Comprehensive corrosion control from design through commissioning and ongoing monitoringImpressed Current Cathodic Protection (ICCP)
Design, supply, and installation of ICCP systems for pipelines, storage tanks, offshore platforms, and marine structures. Includes rectifier sizing, anode groundbed design, and interference testing to ensure system integrity and regulatory compliance.
- Transformer-rectifier unit sizing & installation
- Deep anode groundbed design
- Remote monitoring & data logging
- Stray current interference studies
Sacrificial Anode Systems
Engineering and installation of galvanic (sacrificial) anode systems for applications where impressed current is impractical: including offshore jacket structures, subsea pipelines, vessel hulls, and buried utilities in remote locations.
- Zinc, aluminium, and magnesium anode selection
- Offshore jacket & subsea anode installation
- Pipeline bracelet & ribbon anodes
- Anode consumption monitoring & replacement
CP Surveys & Monitoring
Comprehensive field survey and monitoring services to assess the effectiveness of existing CP systems. We identify protection deficiencies, coating holidays, and stray current interference before they cause corrosion damage.
- Close-interval potential surveys (CIPS)
- Direct current voltage gradient (DCVG) surveys
- Offshore underwater potential surveys
- Annual CP system performance testing
Design, Engineering & Commissioning
NACE/AMPP-certified engineers provide full-scope CP design services: from concept through detailed engineering packages suitable for regulatory approval and construction. We also commission, test, and document all installed systems.
- Detailed engineering design packages
- CP system commissioning & testing
- As-built documentation & handover
- Third-party design review & audit
Corrosion Management & Consulting
Strategic corrosion management advisory for operators seeking to optimise asset integrity, reduce maintenance costs, and meet HSE obligations. Includes risk assessments, CP master plans, and regulatory submissions.
- Corrosion risk assessment (CRA)
- CP master plan development
- NORSOK M-503 & ISO 15589 compliance
- Expert witness & technical dispute support
O&M & Remediation
Ongoing operations and maintenance contracts keeping your CP systems performing to their design intent. For underperforming or failed systems, we provide rapid remediation including retrofit anode installations and rectifier upgrades.
- Annual inspection & maintenance contracts
- Rectifier repair & replacement
- Retrofit anode installation
- Emergency corrosion response
