ICCP Anodes for Marine Structures
Custom MMO tubular, disc, and rod anode solutions for jetties, piers, harbors, seawalls, offshore structures, water intake systems, shipyard facilities, and seawater-exposed impressed current cathodic protection projects.
MARINE ICCP ENGINEERING
Marine ICCP Anodes Must Withstand Seawater, Current Demand and Mechanical Exposure
Marine ICCP systems are used to help protect seawater-exposed steel structures from corrosion. Anode selection should be reviewed according to seawater chemistry, structure geometry, current demand, mounting position, cable sealing, mechanical exposure, marine fouling, inspection access, and design life target.
Unlike buried or concrete CP systems, marine ICCP anodes are exposed to seawater, flow, wave action, impact risk, biological fouling, and installation access limitations. The final anode form, mounting structure, cable route, output rating, and coating requirement should be based on project drawings and operating environment.
Hele Titanium supports MMO tubular anodes, MMO disc anodes, and MMO rod anodes for marine ICCP systems, with coating review, current output review, cable sealing, mounting support, labels, packing, and documentation according to project requirements.
Seawater Application Review
Anode selection can be reviewed based on seawater exposure, salinity, flow, fouling risk, and structure geometry.
Marine MMO Anode Form Matching
Tubular, disc, and rod anodes can be matched to different marine-mounted ICCP layouts.
Cable Sealing & Protection
Cable sealing, mounting brackets, strain relief, and impact protection should be reviewed for seawater applications.
Current Output & Documentation
Current output, coating loading, design life, MTC, records, and project documents supported when required.
What Is Marine ICCP Protection?
Marine ICCP protection is an impressed current cathodic protection method used to help control corrosion on steel structures exposed to seawater or brackish water. It is commonly reviewed for jetties, piers, harbors, seawalls, offshore structures, water intake systems, and other marine infrastructure.
In marine ICCP systems, MMO anodes are installed on or near the protected structure to deliver controlled protective current through seawater. The anode type and layout depend on structure geometry, seawater conditions, current demand, mounting method, cable route, mechanical exposure, and monitoring requirements.
| Marine CP Element | What It Does | Why It Matters |
|---|---|---|
| Protected Steel Structure | The marine steel structure requiring corrosion control. | Structure geometry, coating condition, and exposure zone affect current demand. |
| Seawater Electrolyte | Conducts current between the anode and protected structure. | Salinity, temperature, flow, and fouling conditions affect system design. |
| MMO Anode Layout | Provides impressed current output to the seawater-exposed protection zone. | Anode position, output, and spacing affect protection coverage. |
| Cable & Sealing System | Connects the anode to the power system and protects electrical continuity. | Cable sealing is critical in seawater and splash-zone environments. |
| Mounting & Mechanical Protection | Keeps the anode in the correct position during operation. | Marine impact, wave action, and installation conditions require careful mounting review. |
Recommended MMO Anode Forms for Marine ICCP Systems

Where Marine ICCP Anodes Are Commonly Used
Marine ICCP anode systems are commonly reviewed for seawater-exposed structures where corrosion risk is influenced by salinity, oxygen, flow, coating condition, current demand, and mechanical exposure. The final anode layout should be reviewed according to structure geometry, seawater environment, installation access, and monitoring requirements.

Key Design Parameters for Marine Anode Selection
A reliable marine ICCP anode recommendation requires project data. The anode form, mounting method, cable sealing, current output, coating loading, and documentation should be reviewed based on the full marine CP design.
1. Structure Type & Geometry
Review whether the project is for piles, jetties, piers, seawalls, offshore structures, intake systems, or custom equipment.
2. Seawater Conditions
Salinity, temperature, flow condition, fouling risk, and brackish water exposure can affect design review.
3. Current Demand
Total current, output per anode, current density, and operating profile affect anode quantity and coating loading.
4. Exposure Zone
Submerged zone, tidal zone, splash zone, and atmospheric exposure require different installation considerations.
5. Mounting Method
Bracket-mounted, bolted, suspended, welded support, fixture-mounted, or custom mounting should be confirmed.
6. Cable Route & Sealing
Cable length, insulation, sealing, strain relief, protection route, and junction point should be reviewed.
7. Mechanical Protection
Impact risk, wave action, debris, vessel movement, and maintenance access should be considered.
8. Documentation Requirements
MTC, coating records, dimensional inspection, cable / sealing records, labels, packing list, and project documents.
Marine ICCP Anode System Components to Review
A marine ICCP system is not only the anode. The complete mounting structure, cable system, reference electrodes, power supply, and inspection plan should be reviewed together.
| Component | Review Focus | Buyer Notes |
|---|---|---|
| MMO Anode Form | Tubular, disc, rod, or custom anode form, active area, coating loading, output, and mounting method. | The anode form should match structure geometry and current distribution needs. |
| Mounting Structure | Bracket, bolt, clamp, support frame, fixture, or custom mechanical attachment. | Mounting should consider seawater exposure, mechanical impact, and inspection access. |
| Cable System | Cable length, insulation, sealing, routing, junction box, and mechanical protection. | Cable sealing and route protection are critical in marine environments. |
| Reference Electrodes | Type, quantity, location, cable route, and monitoring access. | Reference electrodes support commissioning and ongoing CP system review. |
| Power Supply / Rectifier | Output current, voltage capacity, control mode, and zone control needs. | Marine CP systems may require careful output adjustment and monitoring. |
| Inspection & Maintenance Access | Anode visibility, diver access, removable mounting, and inspection schedule. | Access planning supports future system review and maintenance. |
Seawater Exposure, Mounting and Cable Sealing Must Be Reviewed Together
For marine ICCP systems, anode selection cannot be based only on tube diameter, disc size, or rod length. Seawater conditions, mounting position, mechanical exposure, current output, cable sealing, inspection access, and design life all affect the final recommendation.
Seawater Chemistry & Flow
Salinity, flow, temperature, fouling, and suspended solids can affect anode and system design review.
Mounting Position
Anode position affects current distribution, protection coverage, and mechanical exposure.
Cable Sealing
Cable sealing and strain relief are critical for seawater, splash-zone, and submerged installations.
Mechanical Protection
Wave action, debris, vessel movement, and maintenance activities should be considered during design review.
Marine ICCP Installation Risk Factors to Review
Many marine CP issues are related not only to anode material, but also to unsuitable mounting, cable damage, poor sealing, high mechanical exposure, marine fouling, or limited inspection access. Reviewing these issues before production helps improve anode selection and project planning.
Incomplete Structure Data
Without structure drawings and exposure zone details, anode location and output assumptions may be less reliable.
Poor Cable Sealing
Weak cable sealing can affect electrical reliability in submerged or splash-zone environments.
Unsuitable Mounting Method
Mounting design should consider impact, vibration, flow, wave action, and future inspection.
Marine Fouling and Deposits
Fouling may affect inspection access, current distribution, and long-term system review.
Mechanical Damage Risk
Debris, vessel movement, currents, or maintenance activities can damage exposed anodes or cables.
Limited Monitoring Access
Reference electrode placement and access points should be considered early in the design.
If your project already has a marine structure drawing, CP design calculation, current demand estimate, seawater data, or installation layout, share it with Hele Titanium for anode form and documentation review.
