MGPS / ICAF
Electrolytic Metal-Ion TreatmentUses controlled copper-ion release for marine-growth control, normally with aluminum or iron / ferrous anodes selected according to seawater-system metallurgy.
Electrochlorination
On-Site Hypochlorite GenerationUses seawater electrolysis to generate sodium hypochlorite for controlled dosing into seawater intake and cooling systems.

ENGINEERING REVIEW
What We Need to Select the Right Anti-Fouling System
Anti-fouling technology and system scope should be reviewed against the complete seawater circuit—not selected from flow rate alone. The following project inputs help determine whether MGPS / ICAF, electrochlorination or a project-specific configuration is more appropriate.
| Engineering Input | What to Provide |
|---|---|
| Vessel / Asset | Vessel type, offshore asset or industrial seawater facility |
| Seawater Duty | Flow rate, operating hours and seawater source |
| Seawater Conditions | Salinity, temperature, operating region and known fouling severity |
| Protected Equipment & Layout | Sea chests, strainers, box coolers, pumps, heat exchangers, pipe sizes and system layout |
| Wetted Materials | Steel, Cu-Ni, titanium, GRP / PVC or other wetted materials |
| Treatment Requirement | Localized intake protection or wider treatment across the seawater circuit |
| Electrical & Control | Available power, control philosophy, monitoring and interface requirements |
| Installation Constraints | Available equipment space, anode / cell locations, cable routing and maintenance access |
| Existing System / Retrofit | Existing make / model, installed equipment, drawings and photographs where applicable |
| Project Requirements | Newbuild, retrofit or drydock schedule, classification, hazardous-area and owner requirements where applicable |
Engineering Note Final system selection should consider seawater flow, fouling conditions, piping metallurgy, treatment coverage, installation layout, electrical supply, maintenance strategy and project requirements together. Anode arrangement, electrolytic-cell duty, dosing philosophy and control scope should be confirmed during application review.

PRODUCT BOUNDARY
Need Hull Corrosion Protection Rather Than Marine-Growth Control?
Marine anti-fouling systems and cathodic-protection systems serve different functions. For hull, offshore structure or submerged-metal corrosion protection, review HELE ICCP and cathodic-protection solutions separately.

Frequently Asked Questions
Common questions about marine anti-fouling systems and selection.
1. What is the difference between MGPS / ICAF and electrochlorination?
MGPS / ICAF uses controlled copper and aluminum/iron ion release from anodes to prevent marine growth, typically suitable for sea chests and compact cooling lines. Electrochlorination generates sodium hypochlorite through seawater electrolysis to dose into the system, often preferred for large-volume intakes, offshore platforms, and complex piping networks.
2. Is MGPS the same as ICCP?
No. MGPS (Marine Growth Prevention System) controls biological fouling inside internal seawater circuits using metal ions. ICCP (Impressed Current Cathodic Protection) prevents electrochemical corrosion on external hull surfaces using protective current. They serve different purposes but are often installed together on vessels.
3. What engineering information is needed for system selection?
To specify the correct system, we review vessel/asset type, seawater flow rate, sea chest count, pipe materials, fouling condition, power/control requirements, class/area rules, drawings, and project schedule.
4. Do you support retrofit and replacement projects?
Yes. We support custom marine anti-fouling system matching for existing seawater pipelines, retrofit projects, shipyard upgrades, and replacement of depleted anodes or outdated control panels.
5. Can we purchase separate anti-fouling components like anodes or control panels?
Yes. HELE supplies individual components including MGPS anodes, electrochlorination cells, control panels, and junction boxes for maintenance, repair, and integration by shipyards or EPC contractors.
6. What inspection and project documentation is provided?
Depending on the confirmed project and order scope, available documentation may include technical datasheets, GA/interface drawings, P&IDs, wiring information, material records, inspection records, FAT records, and operation manuals. To be confirmed by application review.
Before Requesting a Quote
Define the Seawater Circuit Before Selecting the Technology
Marine anti-fouling selection begins with the seawater route, operating profile, materials, target organisms and protected equipment. MGPS and electrochlorination are not interchangeable labels for the same system.
- Map the vessel or asset, seawater circuit, intake points and operating flow.
- State salinity, temperature, operating profile and known fouling conditions.
- Identify piping metallurgy, protected equipment and corrosion constraints.
- Select MGPS, electrochlorination or another route against the approved duty.
- Define controls, installation, dosing or current settings and maintenance responsibility.
Do not release a purchase order with only:
- An “anti-fouling system” request with no selected technical route
- Sizing from nominal flow alone
- MGPS functions confused with hull ICCP functions
- A component quotation treated as an integrated operating system
- Dosing or current settings copied without a site-specific basis
