Cactus Plate Bonding Project With Offshore Client

Plate Bonding is a solution to repair areas damaged by corrosion while extending the life of the structure.

A bespoke training course was created to reflect the planned work at a TR (Temporary Refuge) roof and a production platform in the North Sea for an Oil & Gas client. The Plate Bonding project will be completed using cold bonding techniques.

The workshop opened with the mixing and application of our rapid curing ARC 5 composite to repair pitting and through wall defects in advance of bonding new plates to the roof.

Once the damaged areas were filled, the training introduced mixing and applying ARC 858 Rebuilding and Faring Composite, a ceramic reinforced abrasion control epoxy compound. This composite seals and shims the new plates while providing a solid bond between the new plates and the damaged roof.

Once ARC 858 is applied to the edge of the plates, they are then fitted, with each plate numbered to ensure they fit perfectly. Once the ARC 858 is cured the Ceramic-Polymer STP-EP-HV is injected to fill the remaining cavity between the damaged roof and the new plates, creating a high strength metal composite sandwich.

A Cactus manifold system pumps the injection grade to all four corners of the plate, chasing the product to the centre, where a reservoir is fitted to exhaust any potential air pockets, ensuring the cavity is full.

Once the injection compound cures, the plate bonding process is complete for one plate and the project can move onto repairing the remaining areas until the entire surface is covered. This technique can be used to refurbish drill decks, lay down decks, pipe decks, roofs and many other structures.

Areas damaged by corrosion and erosion will be repaired and our Oil & Gas client’s structure will be strengthened and protected to perform in the most extreme environments.
