Abstract The ingress of moisture into the insulation system and the consequential concentration of chlorides in the insulation enhance the corrosion of insulated parts of the installation. Moisture may even lead to the concentration of corrosive substances from the atmosphere in the insulation system. Therefore consideration must be given to how corrosion of the object can be prevented through appropriate anti-corrosion applications and/or design of the insulation
