ICCP Anodes for Tank Bottom Protection
Custom MMO ribbon, mesh ribbon, wire, and linear anode solutions for storage tank bottom cathodic protection, under-tank ICCP layouts, tank farms, above-ground storage tanks, and distributed current output systems.
Tank Bottom ICCP Engineering
Tank Bottom Protection Requires Distributed Current Output
Tank bottom ICCP systems are used to help protect above-ground storage tank floors from soil-side corrosion. Because the tank bottom is a large, flat structure, the anode layout should be designed to distribute protective current across the protected area as evenly as practical.
Unlike point-type groundbed systems, under-tank ICCP layouts usually require distributed anode forms placed beneath or around the tank bottom. The final anode form, spacing, cable routing, reference electrode location, and current output should be reviewed according to tank diameter, foundation type, soil or sand resistivity, coating condition, current demand, and design life target.
Hele Titanium supports MMO ribbon anodes, MMO mesh ribbon anodes, MMO wire anodes, and MMO linear anodes for tank bottom ICCP systems, with coating review, current output review, cable connection, labels, packing, and documentation support according to project requirements.

Anode forms can be reviewed for distributed current output beneath or around storage tank bottoms.
MMO Linear Anode Form Matching
Ribbon, mesh ribbon, wire, and linear anodes can be matched to the tank layout and current distribution needs.
Tank Diameter & Current Review
Tank size, current demand, anode spacing, and design life target should be reviewed together.
Cable, Monitoring & Documentation
Cable routing, connection, labels, reference electrode coordination, packing, MTC, and coating records can be supported.
What Is Tank Bottom ICCP Protection?
Tank bottom ICCP protection is an impressed current cathodic protection method used to help protect the underside of above-ground storage tank floors from corrosion. In many tank farm projects, anodes are installed beneath the tank bottom, within the foundation system, or around the tank area to deliver protective current to the steel floor.
Answer
Because storage tank bottoms are large and flat, distributed anode layouts are often reviewed. MMO ribbon, mesh ribbon, wire, or linear anodes can be used depending on tank diameter, foundation design, resistivity, installation access, current demand, and project specification.
1. Tank Bottom Steel Floor
What It Does: The protected structure that needs soil-side corrosion control.
Why It Matters: Tank diameter, floor condition, and coating condition affect current demand.
2. Under-Tank Anode Layout
What It Does: Places anodes beneath or around the tank bottom for distributed current output.
Why It Matters: Layout affects current distribution and protection coverage.
3. MMO Linear Anode Forms
What It Does: Ribbon, mesh ribbon, wire, or linear anodes provide distributed current output.
Why It Matters: Different anode forms fit different foundation and installation methods.
4. Cable Routing
What It Does: Connects anodes to the power source and test / junction points.
Why It Matters: Cable route and protection affect long-term system reliability.
5. Reference Electrodes & Monitoring Points
What It Does: Support potential measurement and system commissioning.
Why It Matters: Monitoring layout helps verify and adjust system operation.
Tank bottom ICCP provides distributed current output to protect the underside of above-ground storage tanks.

Current Distribution, Anode Spacing and Foundation Conditions Must Be Reviewed Together
For tank bottom ICCP systems, anode selection cannot be based only on ribbon width or wire diameter. Tank size, foundation conditions, resistivity, anode spacing, cable routing, reference electrode position, current output, and design life all affect the final recommendation.
1 Tank Diameter & Protection Area
Larger tank floors may require more distributed anode layouts and careful spacing review.
2 Foundation Contact
Sand, soil, concrete, liner, or backfill conditions affect current transfer beneath the tank.
3 Output per Meter
Current output per meter should be reviewed according to CP design, coating loading, spacing, and design life.
4 Cable & Monitoring Layout
Cable routes, junction points, reference electrode positions, and access points should be planned early.
* All recommendations are reviewed according to project requirements and based on operating conditions.
Tank Bottom ICCP Installation Risk Factors to Review
Many tank bottom CP issues are related not only to anode material, but also to foundation conditions, poor cable routing, incomplete current demand data, incorrect spacing, or limited monitoring access. Reviewing these issues before production helps improve anode selection and project planning.
Missing Tank Foundation Data
Without foundation details, anode placement and current transfer assumptions may be less reliable.
Incorrect Anode Spacing
Poor spacing can lead to uneven current distribution beneath the tank floor.
Poor Cable Route Planning
Cable exit points, protection, and junction locations should be confirmed before installation.
Limited Reference Electrode Access
Reference electrode placement affects commissioning, monitoring, and long-term CP system review.
Foundation or Liner Constraints
Double bottoms, liners, sand pads, or concrete base designs may affect installation options.
Incomplete Current Demand Review
Current requirement should be reviewed based on tank size, coating condition, environment, and design life.
Buyer Note:
If your project already has a tank drawing, foundation drawing, CP design calculation, current demand estimate, or resistivity report, share it with Hele Titanium for anode form and documentation review.
