Fixed Marine ICCP · MMO Anode Assemblies
MMO ICCP Anodes for Marine & Offshore Structures
Fixed marine structures require anode assemblies that meet both electrical duty and exposed mounting conditions. HELE can configure MMO tubular, disc, rod or custom assemblies for piers, jetties, offshore frames, seawalls and seawater intakes.
The mounting and protection design for a fixed structure should be reviewed separately from a vessel hull ICCP arrangement.

APPLICATION BASIS
Marine ICCP Applications by Structure Type
Fixed marine ICCP systems can protect jetties, piers, offshore jackets, seawalls, intake structures, sheet piling and other immersed steel. The anodes discharge current into seawater while a controlled power source, reference electrodes and monitoring arrangement maintain the project-defined protection criteria.
This page addresses fixed structures rather than automatically treating ship-hull systems as equivalent. Mounting loads, wave and current exposure, burial or shielding, cable routes, diver access, coatings and local current distribution must be reviewed for each asset.
SELECTION FACTORS
Select a Marine Anode Mounting Arrangement
Choose the anode form together with its mounting, dielectric shielding, cable protection and inspection strategy.
Offshore structures
Coordinate anode assemblies with jackets, risers, subsea frames, installation loads and remote monitoring.
Seawalls & sheet piling
Evaluate local current distribution, coating condition, cable routing and anode protection from impact.
Intakes & water systems
Account for flow, screens, debris, nearby materials, access and interaction with anti-fouling systems.
ANODE OPTIONS
Tubular, Disc and Rod Anode Mounting Options
The selected assembly should combine electrochemical duty with a mechanically credible mounting and cable-sealing design.
MMO Tubular Anode
Best considered when: a robust tubular element is mounted on a stand-off, sled, frame or project-specific support.
Confirm: tube geometry, coating/loading, support, dielectric shield, cable exit and handling loads.
MMO Disc Anode
Best considered when: a compact low-profile assembly suits localized or distributed mounting on a designed support.
Confirm: disc size, mounting stud/flange, shield, cable seal, recess and inspection access.
MMO Rod Anode
Best considered when: a slender element suits frames, intakes or localized marine mounting under a defined duty.
Confirm: rod dimensions, holder, insulation, cable connection, support and flow exposure.
Custom Assembly
Best considered when: the project requires a sled, frame, guard or integrated mounting that standard forms do not provide.
Confirm: loads, materials, isolation, fabrication drawing, lifting, cable armor and inspection method.
CONFIGURATION LOGIC
Shields, Coating Interfaces & Local Current Distribution
High local current density near an anode can affect coating and distribution. The marine CP design may use dielectric shields, stand-off distance, zoning and controlled anode placement to manage this interface. Reference-electrode locations and control philosophy should represent the protected zones rather than simply being placed near the anode.
Design control: Do not publish or reuse a generic seawater current density, output or shield size. Final values depend on structure geometry, coating condition, water properties and CP design.
ENGINEERING MATRIX
Marine ICCP Anode & Mounting Inputs
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 |
|---|---|---|
| Structure and zones | Defines current distribution and mounting locations. | General arrangement, immersed area, zones and coating condition. |
| Water environment | Conductivity, temperature and flow affect operation. | Salinity/conductivity, temperature, depth, tidal range, velocity and fouling. |
| Electrical duty | Controls anode size, loading, cable and zones. | Design current, duty per anode, design life and control philosophy. |
| Mechanical mounting | Must withstand installation and service loads. | Mounting drawing, loads, support materials, isolation and guards. |
| Cable route | Submerged connections are critical reliability interfaces. | Cable type/length, armor, seals, penetrations and mechanical protection. |
| Inspection access | Influences replaceability and lifecycle plan. | Diver/ROV access, retrieval method, test plan and maintenance strategy. |
Project review
Treat the Mounting and Cable as Part of the Anode Assembly
The active element alone does not define a marine installation. The support, dielectric interface, cable path and inspection access can control durability and current distribution.
Exposed geometry
Map immersed steel area, tidal and splash zones, coating condition, flow, fouling and possible burial or shielding.
Electrical duty
Confirm current by protection zone, operating voltage, active area, coating basis and the planned reference-electrode positions.
Mechanical interface
Provide support, guard, stand-off, isolation, lifting and installation-load requirements in the approved drawing.
Cable protection
Define insulation, armor where required, route, termination, sealing and access for inspection or replacement.

FAQ
Marine ICCP Anode Procurement Questions
Which MMO anode forms are used on marine structures?
Tubular, disc, rod and custom frame-mounted assemblies are common starting points. Final selection depends on structure geometry, current distribution, mounting, shielding, cable protection and access.
Is this page for ship-hull ICCP systems?
It focuses on fixed marine and offshore structures. Ship systems can have different classification, control, shaft and hull interfaces and should be reviewed as a separate application.
Why is a dielectric shield used near a marine ICCP anode?
A project-designed shield can help manage local current distribution and protect nearby coating. Its material, size and geometry must be confirmed by the marine CP design.
What water data should be provided?
Provide salinity or conductivity, temperature range, depth, tidal variation, flow or current velocity, fouling conditions and any unusual chemistry relevant to the protected zone.
How should submerged anode cables be protected?
The project should define cable construction, armor or conduit, bend limits, sealing, penetrations, supports, abrasion protection and inspection access from the anode to the termination.
Does HELE supply a complete offshore ICCP system?
HELE can supply specified anode assemblies and related components. Full CP engineering, power/control equipment, offshore installation, commissioning and surveys require explicit contractual scope.
