Composites and Coatings for Ships and Offshore Structures

Project Overview

Damaged ships and offshore structures can be repaired and protected against the effects of erosion, corrosion and deterioration using a wide range of Belzona cold curing metal and rubber repair composites and coatings. Our repairs can be easily and safely carried out in-situ, reducing downtime and eliminating the need for hot work.

Belzona’s cold applied metal and rubber repair composites and epoxy coatings offer benefits such as:

  • Excellent erosion and corrosion protection
  • Prolongation of the equipment life
  • Reduction of expensive replacement costs
  • Reduction of downtime
  • Application and cure at room temperature – no hot work involved
  • Fast cure even under waterline
  • Excellent chemical resistance against a wide range of chemicals
  • High temperature and impact resistance
  • Excellent bonding to steel, stainless steel, bronze, copper, GRP, FRP, cast iron and many more

    • Repair and protection of equipment and structures

    Our epoxy repair composites and coatings provide long-term erosion and corrosion resistance for a wide range of marine equipment that operates in a very corrosive marine environment from risers on oil platforms to pilings at jetties.

    Belzona rubber repair composites offer outstanding impact resistance and repair alternatives for rubber clad equipment and fenders, eliminating the need for vulcanization whilst maintaining repair strength. Belzona also offers cold plate bonding solutions for heavily worn and corroded decks, ensuring a rapid and safe alternative to replacement.

    Propulsion system repair

    Corrosion damage of marine propulsion systems can be repaired using a variety of Belzona epoxy repair composites that halt corrosion on such equipment as jet tubes, kort nozzles and bow thrusters, whilst eliminating galvanic effects by isolating exposed metal. Additionally, cylinder liners suffering from cavitation can be repaired without the need for hot work using Belzona cold curing materials such as Belzona 2141 (ACR-Fluid Elastomer) and Belzona 1391 (Ceramic HT). Materials such as Belzona 1121 (Super XL-Metal), and Belzona 1821 (Fluid Metal) are ideally suited for forming equipment such as pintles, bearing housings and bush seats as they are 100% solids, which prevents shrinkage.

    Ancillary equipment

    Belzona’s metal repair composites are frequently used on ancillary equipment on board to repair corrosion and erosion damage that causes metal loss on heat exchangers, valves and pumps. For the best results and protection, a wide range of epoxy coatings is available that offer erosion, corrosion, chemical and temperature resistance.

    Our hand and spray applied internal epoxy coatings for tank lining allow even large tanks to be quickly protected. Many of our coatings are approved for use in contact with potable water.
