CIPS
Close interval potential survey, mapping protection continuously along the route rather than sampling it.
Over-the-Line Surveys
Walking the route to find coating defects, interference and areas the system is not reaching.
Cathodic Protection
Test point readings tell you about the test points. Over-the-line surveys tell you about everything between them, which is where coating damage and under-protection usually hide. These run standalone or as part of a direct assessment programme.
What the work covers
DCVG
Direct current voltage gradient, locating and sizing coating defects with enough precision to dig in the right place.
ACVG
Alternating current voltage gradient, used where DC methods are impractical or as a cross-check.
PCM and ACCA
Pipeline current mapping and AC current attenuation, for tracing current distribution and finding contacts.
Soil resistivity and redox
Environmental measurements along the route, establishing where corrosion risk is concentrated.
GIS mapping
Survey results tied to position, so findings are actionable in the field rather than a list of chainages.
Typical applications
- Pipelines
- Storage tanks
- Buried metallic structures
- Submerged structures
- Offshore and marine structures
- Structural piles
- Industrial facilities
- Reinforced concrete

Location, structure type and any survey work already done is enough for us to say what the next step is.
