MMO Disc Anodes for Marine and Vessel ICCP Systems
HELE manufactures circular MMO-coated titanium disc anodes for marine and vessel ICCP systems, with active geometry, mounting arrangement, electrical duty, cable connection, sealing and hull-interface requirements reviewed against the project design.
Share the vessel or protected structure, required current, target geometry, mounting arrangement, cable requirement and design-life target.
Marine MMO Disc Anode Configurations
MMO marine anodes can be configured in round, oval, elliptical or project-specific shapes according to hull space, mounting position, active-area requirement and ICCP layout.
Round MMO Disc Anode
Circular MMO-coated titanium geometry for compact marine ICCP installations where a defined active surface and compact mounting envelope are required.
Oval MMO Anode
Elongated geometry for vessel areas where installation space or current-distribution requirements favor a longer active form.
Elliptical MMO Anode
Project-specific elongated geometry that can be reviewed against hull layout, available mounting area and required active surface.
Custom Marine MMO Anode
Custom geometry, active area, backing / mounting interface, cable outlet and sealing arrangement can be reviewed according to the approved marine ICCP drawing.
Disc Geometry, Active Area & Technical Specification
Overall geometry, active coated area, mounting envelope and cable interface should be reviewed together because these factors influence installation space, electrical duty and integration with the marine ICCP layout.

Engineering Note:
Overall anode geometry defines the physical installation envelope, while the active coated geometry defines the electrochemically active surface used in the electrical design.
Rated Output Must Be Linked to Active Area & Seawater Conditions
Current output per marine disc anode should be reviewed together with active coated area, current-density basis, seawater condition, MMO coating requirement, mounting layout and the project design-life target.
Active Coated Area
The exposed MMO active surface forms the basis for electrical output calculations and must match the confirmed product geometry.
Current-Density Basis
Project current density should be defined according to the seawater environment, coating requirement and ICCP system design.
Output per Anode
Rated output should be established from the verified active geometry and approved electrical design rather than from external dimensions alone.
Design-Life Basis
Design life should be linked to coating loading, rated electrical duty, seawater conditions and the approved ICCP design.
Final rated output and design life must be confirmed against the active geometry, MMO coating requirement, seawater conditions, mounting arrangement and project electrical design.
Mounting, Hull Interface & Dielectric Shield
Marine disc-anode selection should include the complete hull or structure interface—not only the active MMO surface. Mounting geometry, backing arrangement, cable access and surrounding ICCP layout should be reviewed against the vessel drawing.
Mounting Interface
Hull-mounted, flush-mounted, bolted, backed and project-specific mounting arrangements can be reviewed according to the existing installation envelope and drawing.
Backing & Mechanical Interface
Backing plate, flange, bolt pattern, thread, rubber seal or other source-page mounting concepts can be customized according to the confirmed vessel design.
Dielectric Shield Interface
Where the marine ICCP design specifies a dielectric shield around the anode, its geometry and location should be treated as part of the complete system design.
Cofferdam / Internal Access
Where a vessel drawing includes an internal cofferdam or protected cable-access arrangement, the anode interface should be reviewed against that installation design.
Cable Connection, Sealing & Assembly Verification
The electrical connection behind a marine MMO anode should maintain continuity while protecting the cable interface against seawater exposure, installation damage and mechanical stress.
Cable Outlet
Rear, side or project-specific cable outlet arrangements can be reviewed according to the installation space and vessel drawing.
Cable Connection
The active MMO electrode and conductor interface should follow the confirmed electrical and mechanical assembly design.
Sealing
Existing HELE source-page options include epoxy, rubber, flange and project-specific marine sealing concepts. Final selection should follow the actual installation requirements.
Electrical Inspection
Continuity, connection condition, cable interface and other agreed project-specific electrical checks can be included according to the inspection scope.
Where MMO Disc Anodes Are Used
Vessel Hull ICCP
Compact disc, round, oval or elliptical MMO anodes can be integrated into ship-hull ICCP layouts where a localized marine active surface is required.
Marine & Offshore Structures
Project-specific MMO disc or oval geometries can be reviewed for marine and offshore steel structures according to current demand, mounting support and cable protection requirements.
Seawater Intake & Marine Equipment
Compact MMO active electrodes can be reviewed for suitable seawater-intake or marine-equipment applications according to salinity, water flow, current requirement and mounting arrangement.
Retrofit ICCP Projects
Custom geometry can be reviewed against existing hull openings, installation zones, backing structures, cable routes and replacement drawings.
Custom MMO Disc Anodes Built Around Your Marine ICCP Layout
Disc geometry, active coated area, electrical duty, mounting arrangement, cable outlet and sealing can be reviewed around the vessel or marine-structure ICCP design.

Disc Anode vs Rod & Tubular MMO Anodes
| Product | Geometry | Main Selection Direction | Link |
|---|---|---|---|
| MMO Disc Anode | Flat circular / oval / elliptical active electrode | Marine ICCP requiring compact, surface-mounted or flush-mounted geometry | This page |
| MMO Rod Anode | Solid cylindrical MMO active electrode | Compact rigid electrode form for localized or project-specific installation | View Rod → |
| MMO Tubular Anode | Hollow cylindrical MMO-coated titanium active electrode | Cylindrical ICCP active geometry for soil, water or project-specific assemblies | View Tubular → |
Disc, rod and tubular MMO anodes are different active-electrode geometries. Final selection depends on the protected structure, installation envelope, electrical duty and ICCP system design.
