EXAMPLES OF WILSON WALTON INTERNATIONAL’S CATHODIC PROTECTION SYSTEMS
Ship Hulls (Commercial & Naval Vessels)
Protection Type:
- Impressed Current Cathodic Protection (ICCP) using Aquamatic® systems
- Galvanic/Sacrificial Anodes (Zinc or Aluminum)
Typical Installations:
- Bulk carriers
- Container ships
- Tankers
- Naval vessels (e.g., frigates, patrol boats)
Components Used:
- Hull-mounted anodes
- Reference electrodes
- Aquamatic control units
- Control monitoring and feedback loops
Offshore Platforms & Structures
Protection Type:
- Primarily Galvanic Anode Systems (Zinc or Aluminum)
- Sometimes Hybrid ICCP Systems for long-term efficiency
Applications
- Oil and gas production platforms
- Offshore wind turbine foundations
- Subsea manifolds and conductors
Installation Features:
- Weld-on or clamp-on anodes
- Custom anode sleds
- Retrofitted ICCP for aging structures
Ballast Tanks, Sea Chests, and Water Compartments
Protection Type:
- Zinc Anodes due to safety requirements (non-sparking)
Applications
- Cargo ship internal tanks
- Engine cooling systems
- Fire-fighting water intakes
Anode Placement:
- Welded or bolted directly to the interior metal surfaces
- Often replaced or inspected during dry-dock
Harbor, Jetty & Pier Structures
Protection Type:
- Sacrificial Zinc or Aluminum Anodes
Applications
- Sheet piles
- Steel pilings
- Mooring dolphins
- Wharf structures
System Notes:
- Designs tailored to tidal exposure and water salinity
- Long-life anodes often built into pile wraps or clamps
Subsea Pipelines
Protection Type:
- Hybrid Cathodic Protection Systems
- Distributed Aluminum or Zinc bracelet anodes
Applications:
- Oil & gas pipelines
- Water and wastewater lines
Features:
- High-output bracelet anodes
- Mounted at intervals along pipeline length
- ICCP booster stations used in deep or high-resistivity areas
Dry Docks and Floating Docks
Protection Type:
- ICCP Systems with Aquamatic control for fine regulation
Applications:
- Graving docks
- Floating dry docks
- Naval maintenance bases
Benefits:
- Minimized maintenance
- Control of corrosion during vessel lay-ups
- High automation and energy efficiency
Wilson Walton International provides cathodic protection solutions across a wide range of industries, with systems tailored to both marine and industrial applications. Common uses include protecting ship hulls, offshore oil and gas platforms, subsea pipelines, harbor structures, ballast tanks, and dry docks from corrosion. They offer both sacrificial anode systems (using high-purity zinc or aluminum) and advanced Impressed Current Cathodic Protection (ICCP) systems like their Aquamatic® line. These solutions are designed to extend the service life of metal structures exposed to harsh marine or industrial environments by preventing electrochemical corrosion.
