Marine vessels routinely face varied and adverse operating conditions and the task of ensuring continued seaworthiness by keeping every component in working order is a true engineering challenge.
Rezitech, Belzona, Sponge- Jet and NRX Nanoprime provide many solutions for the marine industry.
From major marine classification society approved repairs on large ships, power or sail Superyachts, commercial vessels, ferries, military vessels, fishing vessels or pleasure craft, we can assist with emergency, temporary or permanent repair solutions to erosion, corrosion, electrolytic attack and accidental damage.
Common applications include
- reforming of rudder pintle housings with specialised Belzona metallic polymers
- repair and protection of jet tunnels on large catamarans
- overboard exhaust and stub pipe lining to combat corrosion damage
- cavitation damage repairs to propellers, bow thrusters, kort nozzles and rudders.
- Repair and protection of stern tubes
- Reforming or restoration and machine of corroded flanges
- Elimination of bi metallic corrosion between components
- “cold bonding” where welding is either difficult or impossible to perform.
- Underwater or wet surface repair to hulls, fuel tanks, ballast tanks.
- In situ worn shaft rebuilds
- Chocking and shimming of engines, gearboxes, bearing housings, support brackets with Belzona classification society approved products.
Many marine applications require surface preparation by grit blasting which often poses problems with damage to nearby equipment, other vessels and personnel. In applications such as these or in confined spaces, our Sponge Jet low dust, recyclable blasting system is ideal.
Where is it not possible to perform blasting we have surface tolerant products that provide good adhesion to substrates with little surface preparation or will bond to substrates that are wet, immersed or oil contaminated.
Marine coatings require a degree of surface preparation prior to application but often preparation by abrasive blasting is not practical. In these cases, NRX Nanoprime is an excellent option. NRX Nanoprime is a specialised system that is applied to substrates prepared by water blasting and is compatible with a multitude of common, non solvent based top coats.
ReziSafe’s environmentally friendly ReziCAS chemical replacement range is used widely in the marine industry. From safe solvents to biodegradable degreasers, our ReziCAS range keeps people safe and the waterways clean.
Rezitech has over 50 years’ experience servicing the marine industry. When you need help, please contact us to draw on our extensive knowledge and experience.
