ABSTRACT:
A method and apparatus for forming inspection apertures through the insulation cladding of a containment vessel by forming an opening partly through the cladding which is thereafter lined by an adhered liner. The depth of the liner is less than the thickness of the cladding, thereby precluding heat transfer thereacross. The removed plug of the insulation is then fixed by an adhesive spray about its exterior, and once cured can then be replaced into the liner to recreate substantially identical insulative qualities. On replacement, a bridging cover is adhered across the liner to maintain the weather integrity of the cladding. This cover may be removed on successive occassions to allow for repeated inspection of the vessel walls.
