Corrpro Europe (formerly Wilson Walton UK) is a global leader in impressed current and galvanic (sacrificial) cathodic protection and marine growth prevention antifouling systems.

As an original equipment manufacturer, we have supplied many thousands of systems to vessels and offshore assets worldwide—including commercial vessels, tankers, cruise ships, naval ships, FPSOs, and platforms. Our solutions are trusted across the marine and offshore industries for their performance, reliability and longevity. For Corrpro Europe’s wider capabilities across onshore and offshore infrastructure, explore our cathodic protection systems, products and services.

We design, manufacture, and support a full range of cathodic protection and antifouling technologies, including Aloline® and, Zincoline galvanic anodes, Aquamatic® ICCP systems, and Anfomatic® MGPS units, as well as shaft grounding systems and remote monitoring solutions. All systems are tailored to vessel requirements, built for durability, and supported by extensive stocks of genuine spare parts for both legacy Wilson Walton systems and other manufacturers. 

With a global network of experienced service engineers ready to respond on short notice, we offer fast delivery, rapid response to enquiries (typically within a few days), and comprehensive lifecycle support—ensuring maximum uptime and protection for your assets.

Galvanic Anode Cathodic Protection for Hulls and Structures

Corrpro Europe supplies Aloline® and Zincoline galvanic anodes in aluminium and zinc alloys for hull, tank and subsea protection. Cast at our UK foundry, these galvanic anodes deliver consistent protection for steel hulls, ballast tanks, box coolers and other submerged metallic structures to ensure effective galvanic protection of iron and steel in marine environments.

Aquamatic® ICCP Systems with Advanced Control Capabilities

Our Aquamatic® impressed current cathodic protection systems are designed for maximum efficiency and performance. Each system includes MMO or platinised titanium ICCP anodes, Ag/AgCl or Zinc reference electrodes, and transformer rectifier units. With traditional power units and six-pulse technology, closed-loop control, and shaft grounding, Aquamatic® systems maintain optimal cathodic corrosion protection for vessels of all sizes

Marine Cathodic Protection Applications

Marine cathodic protection systems must account for the different corrosion risks found across submerged and internal metallic structures. Corrpro Europe provides engineered protection for vessels and offshore assets, including:

  • Hull structures – protecting submerged steel continuously exposed to seawater.
  • Ballast tanks – providing corrosion protection for internal steel exposed to changing operating conditions.
  • Rudders and shafts – protecting submerged components exposed to seawater and galvanic interaction.
  • Sea chests and associated structures – protecting metallic surfaces within seawater intake areas.
  • Offshore structures and FPSOs – providing cathodic protection for complex assets operating in demanding marine environments.

System selection depends on the structure, operating environment, coating condition, current demand and required design life. Corrpro Europe designs both galvanic and impressed current cathodic protection systems around the specific requirements of the vessel or offshore asset.

MGPS and Antifouling

Our Anfomatic® Marine Growth Prevention Systems (MGPS) release controlled amounts of cupric ions to protect seawater intakes and internal vessel pipework, including sea chests, strainers, and box coolers, from biofouling. By preventing marine growth, these systems lower maintenance costs and enhance efficiency across vessels as well as internal piping and cooling water infrastructure—all without the need for harsh chemicals or mechanical cleaning.

Marine Cathodic Protection FAQs

How does cathodic protection protect a ship’s hull?

Cathodic protection controls corrosion by polarising the submerged steel surface to a more negative potential. Protection is provided using either galvanic anodes or an impressed current cathodic protection system.

What is the difference between marine ICCP and galvanic anodes?

Galvanic systems use sacrificial aluminium or zinc anodes to provide protective current without an external power source. ICCP systems use powered anodes and controlled current, allowing protection levels to be adjusted to suit the vessel or structure.

How is a marine ICCP system monitored?

Reference electrodes measure the electrical potential of the protected structure and provide feedback used to regulate ICCP output. System performance can also be assessed through operational checks and remote monitoring where fitted.

Can existing marine cathodic protection systems be maintained or upgraded?

Yes. Corrpro Europe supports existing Corrpro and legacy Wilson Walton systems, as well as equipment from other manufacturers, with technical assessment, replacement parts, troubleshooting and system upgrades where required.
