Project: Plate Bonding Offshore
The surface was severely corroded
Once the surface is prepared, ARC 5 Emergency Metal to Metal Repair Epoxy filled pitting and through wall defects
ARC 858 Rebuilding and Faring Composite composite seals, shims and bonds the new plates to the surface
A manifold system pumps Ceramic Polymer Adhesive injection grade material
The surface is repaired and protected from future erosion, corrosion and chemical attack
A high strength, cold bonding system proved a quick and effective solution in ensuring ensured the deck was back in operation and protected against erosion, corrosion and chemical attacks.
A client’s Temporary Refuge roof, located on their offshore platform, had suffered severe corrosion damage. Cactus high performance composite technology was used to plate bond the entire surface. Plate bonding repairs the damage and protects the structure from future erosion, corrosion and chemical attacks.
Step 1: Surface preparation is the necessary first step in any repair project. The Bristle Blaster easily and effectively removes corrosion, mill scale and coatings. It is ATEX approved for use in Zone 1 (potentially explosive applications) and combines the ability to produce an abrasive blasted finish with the high mobility and flexibility of a portable hand-held tool.
Step 2: ARC 5 Emergency Metal to Metal Repair Epoxy technology was used to rebuild pitted and scored surfaces. Then, ARC 858 Rebuilding and Faring Composite was applied to each plate in order to seal, shim and bond the plates to the surface.
Step 3: A Cactus manifold system pumps Ceramic Polymer Adhesive injection grade material to all four corners of the plate, chasing the product to the centre. A reservoir is fitted to exhaust any potential air pockets, ensuring the cavity is full.
Step 5: The injection compound cures. One plate is now fitted and secured. The plate bonding project continues until all plates are fitted and the entire surface is repaired.
The roof surface of an offshore platform's temporary refuge had suffered serious corrosion damage.
Cactus client required a quick, high performance solution that would ensure minimal down time and extend the operating life of the structure.
After preparing the surface and removing all corrosion and coatings, Cactus ARC 5 Polymer Blend was used to rebuild pitted and scored surfaces.
ARC 858 Abrasion Resistant Rebuilding and Faring Composite was then applied to each plate in order to seal, shim and bond the plates to the surface.
The injection grade material was then pumped through a manifold system, ensuring a high performance bond between the plates and the surface.
Cactus technology ensured the roof was completely repaired and the operating life of the structure extended.
This structure is now protected for the long term against erosion, corrosion and chemical attack in an extreme offshore environment.
This technique can be used to refurbish drill decks, lay down decks, pipe decks, roofs and many other structures.
