Buried Structures
Compare remote deep or shallow groundbeds with distributed linear layouts using soil resistivity, coating condition and interference risk.
ICCP Anode Layouts · Selection Overview
ICCP Anode Installation Configurations by Structure and Environment
Compare remote groundbeds, distributed anodes, under-tank layouts, concrete installations and marine-mounted arrangements from the protected asset and its environment. HELE can configure the anode supply once the required current, installation interfaces and design basis are defined.
The responsible CP designer confirms final current demand, placement, interference review, protection criteria and commissioning method.

APPLICATION BASIS
How ICCP Installation Configurations Differ
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.
SELECTION FACTORS
Choose a Layout by Structure and Electrolyte
Start with the protected asset and installation environment, then compare current distribution, access and lifecycle requirements.
Tank Bottoms
Evaluate grid, mesh-ribbon or concentric linear arrangements against tank foundation, liner, replacement-bottom and monitoring details.
Reinforced Concrete
Select mesh, ribbon, wire or discrete arrangements from concrete condition, reinforcement continuity, repair zones and overlay method.
Marine Structures
Review tubular, disc or rod assemblies for seawater current distribution, shielding, cable protection and diver access.
ANODE OPTIONS
Common ICCP Anode Configuration Families
These are configuration families, not pre-approved designs. The project specification determines dimensions, coating loading, cable, seals, backfill and assembly details.
Remote Groundbed Anodes
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.
Distributed Linear Anodes
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.
Ribbon & Mesh Systems
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.
Marine-Mounted Anodes
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.
CONFIGURATION LOGIC
Remote Groundbeds vs Distributed Anodes
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.
ENGINEERING MATRIX
Configuration Decisions to Confirm Before Supply
Use these inputs to define the quotation and the approved anode supply schedule. The CP designer confirms the final design values.
| 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. |
Project review
Check the Installation Interfaces Before Choosing an Anode Form
The anode form follows the approved CP layout. These four checks prevent a quotation for an electrode alone from being compared with a complete installable assembly.
Current path
Confirm the protected zones, coating condition, electrolyte and distribution model before fixing anode spacing or number.
Physical route
Show boreholes, trenches, tank foundations, concrete cover or marine mounting points on the issued layout.
Electrical interfaces
Define leads, junctions, reference electrodes, cable protection, power supply and field termination responsibilities.
Acceptance evidence
Agree the shop inspection, installation checks and commissioning records that belong to each supplier or contractor.

FAQ
ICCP Installation Configuration Questions
How do I choose between a remote and distributed ICCP anode layout?
Compare soil or electrolyte properties, structure geometry, coating condition, required current distribution, interference risk, installation access and lifecycle maintenance. The responsible CP designer should confirm the final layout.
Can one MMO anode type be used for every ICCP application?
No. MMO coating is used in several forms, but the titanium substrate, geometry, cable, seals, mounting and operating environment must match the application.
What information is needed before selecting an installation configuration?
Provide structure drawings, electrolyte data, coating information, design current, protection zones, site constraints, cable routes, monitoring requirements and the target design life.
Does HELE provide the complete cathodic-protection design?
HELE supplies anode components and assemblies to the agreed specification. Complete CP design, rectifier sizing, interference analysis, installation and commissioning are included only when explicitly contracted.
Are the layouts on this page construction drawings?
No. They explain configuration logic. Project drawings, dimensions, spacing and current-output requirements must be issued or approved by the responsible project engineer.
What should be included in an anode-supply RFQ?
Include the application, structure and electrolyte data, design current, anode form, dimensions, coating/loading basis, cable and termination details, backfill or mounting scope, documents, quantity, delivery location and schedule.
