Conventional repairs which may include traditional coatings and re-strengthening or replacement of equipment are not popular as this work can only be done in a costly shutdown period. In-situ repairs which can be applied outside the shutdown period would be the first choice, but the problem with CUI is that such repairs are traditionally difficult to complete due to the following reasons;

• Surfaces are too hot to directly apply products
• There is normally the requirement to bond to manually prepared surfaces
• Hot work is normally not allowed

It is therefore essential for any solution provider that they address all of these challenges so that this work can be applied in-situ and outside the planned shutdown periods.
