Assessment of service worthiness aims at outlining the ability of an asset to perform its intended function effectively and efficiently while protecting health, safety, and the environment over the whole life cycle. Assets have traditionally been built with an assumed nominal design/economic life of about 20-25 years. Depending upon the actual operating and environmental conditions, materials of equipment degrade as a function of service life due to one or more time dependent material damage mechanisms such as creep, fatigue, corrosion, erosion, wear, and embrittlement.
