Buried Structures
Compare remote deep or shallow groundbeds with distributed linear layouts using soil resistivity, coating condition and interference risk.
Compare remote groundbeds, distributed anodes, under-tank layouts, embedded concrete systems and marine-mounted arrangements before choosing an MMO anode form.
This page is a selection hub, not a substitute for project-specific cathodic-protection design. Current demand, placement, interference and commissioning criteria must be confirmed by the responsible CP designer.
An ICCP layout is selected from the structure geometry, electrolyte, coating condition, current demand, access, cable routing, installation method and monitoring strategy. The same MMO coating can be packaged as a canister, tubular, linear, wire, ribbon, mesh ribbon, disc or rod assembly, but these forms are not interchangeable without design review.
Remote groundbeds concentrate anodes away from the protected structure, while distributed arrangements place anodes near the areas requiring current. Under-tank, concrete and marine systems add structure-specific constraints such as foundation layers, cover depth, seawater exposure, mounting protection and inspection access.
Start with the protected asset and installation environment, then compare current distribution, access and lifecycle requirements.
Compare remote deep or shallow groundbeds with distributed linear layouts using soil resistivity, coating condition and interference risk.
Evaluate grid, mesh-ribbon or concentric linear arrangements against tank foundation, liner, replacement-bottom and monitoring details.
Select mesh, ribbon, wire or discrete arrangements from concrete condition, reinforcement continuity, repair zones and overlay method.
Review tubular, disc or rod assemblies for seawater current distribution, shielding, cable protection and diver access.
These are configuration families, not pre-approved designs. The project specification determines dimensions, coating loading, cable, seals, backfill and assembly details.
Best considered when: the protected asset can be served from a separated deep or shallow groundbed.
Confirm: soil model, remote-earth behavior, borehole or trench details, backfill, venting and cable route.
Best considered when: current should be distributed along pipelines, tank perimeters or localized buried assets.
Confirm: routing, attenuation, spacing, joints, termination, backfill and interference review.
Best considered when: a low-profile distributed layout is needed under tanks or in concrete zones.
Confirm: grid geometry, crossing connections, substrate preparation, overlay or foundation interface.
Best considered when: anodes are mounted to jetties, offshore frames, seawalls or intake structures.
Confirm: mounting, dielectric shield, cable sealing, mechanical protection and inspection access.
A remote groundbed can simplify anode concentration and maintenance access, but its resistance, attenuation and interference effects depend on site conditions. A distributed arrangement can improve local current distribution, yet it creates more cable, splice and installation interfaces. Selection should be based on the complete CP model rather than anode shape alone.
Design control: Do not use a generic spacing, current-output or design-life value across different structures. Those values are project outputs, not fixed product specifications.
The following items define the supply basis. Final values are confirmed by the cathodic-protection designer and project review.
| Decision | Why it matters | Evidence to provide |
|---|---|---|
| Protected structure | Defines current distribution and mounting geometry. | Structure drawings, dimensions, coating data and electrical continuity. |
| Electrolyte | Soil, concrete and seawater require different installation interfaces. | Resistivity or conductivity, temperature, chemistry and seasonal variation. |
| Current demand | Drives anode quantity, loading, cable and power-system inputs. | Design current, zones, design life and governing calculation. |
| Access & Constructability | Controls groundbed, trench, embedding, mounting and replacement strategy. | Site plan, work method, lifting/access limits and installation sequence. |
| Monitoring | Reference electrodes and test points support control and verification. | Monitoring philosophy, locations, cable schedule and acceptance plan. |
