Design, Corrosion Assessment and Consultancy

R & R Corrosion Ltd provides specialist cathodic protection design and consultancy services tailored to each client’s assets, operating conditions and project requirements.

Our experienced corrosion engineers support new installations, modifications, upgrades and life-extension projects for pipelines, tanks, marine structures and other buried or immersed metallic assets. We can assist from the initial feasibility stage through detailed design, installation, commissioning and long-term system monitoring.

Our services include:

• Review of existing cathodic protection systems and survey data
• Site surveys and collection of design information
• Sacrificial-anode and impressed-current system design
• Assessment of coating condition and CP current demand
• Anode and groundbed selection, sizing and positioning
• Transformer-rectifier and cable sizing
• Electrical continuity and isolation requirements
• Design of test posts and permanent monitoring facilities
• AC, DC stray-current and third-party interaction assessments
• Preparation of design calculations, drawings and specifications
• Material selection and preparation of equipment schedules
• Installation supervision and commissioning support
• System troubleshooting and remedial-work recommendations
• Independent technical reviews and specialist advice

We work closely with clients to develop practical, reliable and cost-effective solutions that meet the asset’s required protection level and design life. Every design considers coating condition, environmental resistivity, electrical interaction, accessibility, maintainability and future monitoring requirements.

Our deliverables can include basis-of-design documents, engineering calculations, drawings, material schedules, installation procedures, commissioning requirements and technical reports. R & R Corrosion can also supply the specified materials and provide installation, testing and ongoing maintenance support, giving clients a complete cathodic protection service from a single specialist provider.
