Saltwater Exposure Risk

Saltwater Corrosion Protection

Marine environments are among the most aggressive operating conditions for metal equipment. Constant exposure to saltwater, humidity, and marine air accelerates corrosion on hardware, cables, and exposed steel surfaces.

Prolan products are widely used across marine vessels and offshore equipment to reduce corrosion, protect components, and extend service intervals. Lanolin-based coatings create a long-lasting barrier that prevents saltwater and moisture from reaching metal surfaces.

Applications

  • Wire ropes and lifting cables – apply Prolan Heavy for marine corrosion protection
  • Stainless steel hardware and fittings – coat with Prolan Grease to prevent seizing
  • Engine bays and electrical terminals – protect with Prolan Enduro
  • Hydraulic hoses, pulleys and moving components – maintain smooth operation with lanolin protection

TESTIMONIAL

Protecting Recovery Equipment in One of New Zealand’s Largest Maritime Cleanups

During the recovery operation following the Rena grounding on Astrolabe Reef near Tauranga, crawler cranes were deployed on a barge to remove containers from the wreck over an extended period in harsh saltwater conditions.

Prolan Heavy was applied to the cranes’ steelwork and wire ropes to create a protective lanolin barrier against corrosion. The coating provided long-lasting protection throughout the operation and could be reapplied at sea if required, helping protect critical equipment while supporting environmentally responsible recovery work.

APPLICATION

Lower Total Cost of Protection

Longer service intervals result in fewer reapplications, reduced labor requirements, less operational downtime, and lower overall product consumption.

When maintenance cycles are extended, site visits become less frequent, and environmental handling exposure is reduced. Protection that lasts longer supports both operational efficiency and long-term sustainability objectives.
