A LIFETIME OF INTEGRITY--OVERCOMING THE CHALLENGES IN MANAGING THE LIFE-CYCLE OF AGING ASSETS

摘要

Life-cycle management, more commonly known as Asset Integrity Management, like with anything, begins as a concept. Thought is then given to the design, the metallurgy, the thickness, resistance to degradation, and many other factors that give an asset its character and allow it to perform in the environment it must operate. Once conceived, designed and fabricated, the stamp of approval is placed and its life-cycle begins. Throughout its life, the management of an asset's integrity may involve some challenges. The dynamic nature of operations, including start-ups and shutdowns, process upsets (excursions), environmental factors, and external incidents may alter an asset's ability to achieve and maintain its desired levels of integrity and reliability. Despite these challenges, through properly implemented mechanical integrity, maintenance and operations programs, assets can produce a favorable return on investment and operate optimally for many years. Though they may experience a few "bumps" and "bruises", with effective integrity management, an asset's health can remain intact throughout its lifetime.
