System selection
Sacrificial or impressed current, decided on current demand, soil resistivity, coating quality and whether a power supply is realistic at the site.
Cathodic Protection System Design
Choosing the right system for the structure, the soil and the budget, then documenting it well enough to build from.
Cathodic Protection
Design is where a cathodic protection system is won or lost. The decision between sacrificial anodes and impressed current, the current demand calculation, the anode placement: get these wrong and no amount of careful installation will save the asset. We design for the structure in front of us rather than applying a template.
What the work covers
Current demand calculation
Sized against surface area, coating condition and the environment, with headroom for coating degradation over the design life.
Anode layout
Placement and groundbed design that distributes protection evenly instead of over-protecting one end and starving the other.
Drawings and specifications
Detailed drawings, material specifications and a bill of materials precise enough to procure and build from without guesswork.
Procedures and test plans
Installation procedures, inspection test plans and method statements, so the people on site know what good looks like.
Client standards
Designs written to your specifications and the standards your operation is audited against, not to a generic template.
Typical applications
- Pipelines
- Storage tanks
- Buried metallic structures
- Submerged structures
- Offshore and marine structures
- Structural piles
- Industrial facilities
- Reinforced concrete
