Marine Coating & Asset Protection Solutions
Specialist Corrosion, Erosion & Cavitation Protection for Vessels, Port Infrastructure & Offshore Assets
Marine enviroments represent some of the most aggressive operating conditions on earth. Constant exposure to seawater, salt spray, tidal cycling, biofouling and intense mechanical stress creates a relentless attack on vessel hulls, propulsion systems, port infrastructure and offshore assets, accelerating corrosion and erosion at rates that can cause significant damage within months rather than years.
Corrotec delivers specialist engineered coating solutions specifically designed for the marine environment, protecting, restoring and extending the operational life of critical marine assets across commercial shipping, ports and harbours, offshore energy and naval sectors.

Why Marine Assets Need Specialist Protection
Seawater is one of the most corrosive environments a metal structure can be exposed to. The combination of dissolved salts, oxygen, biological activity and constant mechanical movement creates an electrochemical attack on steel and alloy components that is ten times more aggressive than typical atmospheric corrosion, reducing fabricated steel integrity rapidly and causing expensive asset failure if left unmanaged.
Add to this the effects of cavitation, erosion, impact damage, marine growth and the constant thermal cycling of immersed components, and the case for specialist protective treatments becomes overwhelming. The cost of proactive protection is always a fraction of the cost of reactive replacement, particularly in a sector where vessel downtime directly translates to lost revenue.
Marine Corrosion Protection
Corrotec specifies and applies specialist ant-corrosion coating systems engineered to withstand the specific demands of the marine environment, providing long-term protection for vessel hulls, structural steelwork, port infrastructure and offshore assets against the relentless elecrochemical attack of immersion, splash zone and atmospheric marine exposure.
Applications include:
- Vessel hulls and topsides
- Port and harbour steelwork and piling
- Offshore platform structural components
- Jetties, pontoons and marine structures
- Pipework, valves and mechanical fittings
- Below waterline and splash zone protection
Cavitation Corrosion/Erosion
Cavitation is one of the most destructive forces acting on marine propulsion components. When operating pressures drop below the vapour pressure of the surrounding fluid, microscopic gas bubbles form and collapse violently against metal surfaces, creating intense localised impact forces that cause progressive erosion, severe pitting and ultimately structural failure of the affected component.
Corrotec delivers specialist cavitation repairs and protection solutions that restore damaged components to original profile and protect against future cavitation attack, significantly extending component service life and reducing the frequency and cost of replacement.
Applications include:
- Propellers and propeller shafts
- Jet tubes and Kort nozzles
- Bow and stern thrusters
- Rudder leading edges
- Stern tubes and seal housings
- Engine casings and A frames
- Pump impellers and casings in marine service
Kort Nozzle Lining & Protection
Kort nozzles operate in an extremely aggressive environment, subject to constant cavitation, erosion, corrosion and the additional complexity of de-chlorination requirements before any protective treatment can be applied.
Corrotec has extensive experience in the specialist preparation and lining of Kort nozzles using high performance ceramic polymer coating systems, delivering outstanding cavitation and corrosion resistance and significantly extended service intervals.
Applications include:
- Kort nozzle internal and external lining
- De-chlorination pre-treatment
- Ceramic polymer protective coating application
- Surface restoration and profile rebuilding
- Ongoing maintenance coating programmes

Marine Composite Metal Repair
& Rebuilding
Marine components subject to erosion, corrosion or impact damage can frequently be returned to full specification using high performance composite repair systems, eliminating hot works, avoiding the cost and lead time of OEM replacement, and getting vessels back into service faster.
Composite metal repair in the marine environment requires specialist knowledge of substrate preparation in saltwater contaminated conditions, an area where Corrotec's experience and certified manufacturer systems deliver reliable, durable results.
Applications include:
- Propeller shaft and bearing housing repair
- Hull plate reosion and corrosion repair
- Thruster body and housing restoration
- Valve and pump body rebuilding
- Structural component profile restoration
Thermal Sprayed Aluminium - Long Term Marine Corrosion Protection
Thermal sprayed aluminium coatings provide outstanding long-term corrosion protection in marine and offshore environments, recognised by international standards as delivering over 20 years to first maintenance in highly corrosive marine conditions. With superior bond strength, precise thickness control and no thermal distortion risk, TSA coatings are ideal for complex marine fabrications and structural components where conventional paint systems would have limited service life.
Applications include:
- Offshore structural steelwork and fabrications
- Vessel superstructure and deck fittings
- Port and harbour infrastructure
- Subsea components and risers
- Complex geometry marine fabrications
- Exposed valves and process equipment
Marine Deck Anti-Slip & Safety Surfacing
Safe working surfaces are critical on vessels and marine structures, where wet, contaminated and constantly moving deck surfaces create serious slip hazards for crew and operational personnel. Corrotec specifies and applies durable, high-grip anti-slip surfacing systems designed specifically for the demands of the marine enviroment - providing reliable traction under wet, oily and heavily trafficked conditions.
Applications include:
- Vessel deck and walkway surfaces
- Offshore platform grating and walkways
- Port and harbour access routes
- Engine room and machinery spaces
- Gangways and access structures
- Vehicular ramps and load areas
Marine Pipework Protection & Pipe Wrapping
Immersed, exposed and buried pipework in marine and port environments face intense corrosion attack from seawater, marine growth and aggressive ground conditions. Corrotec's pipe wrapping and protective coating solutions provide durable long-term protection for marine pipework, outfalls and fittings, extending service life significantly and reducing costly replacement programmes.
Application include:
- Immersed and tidal zone pipework & piles
- Port and harbour outfalls and fittings
- Buried coastal and marine pipelines
- Offshore riser and subsea pipework protection
