In the eight years since the first edition of this book was published by NACE International, the demand for corrosion management expertise and services (i.e., training, auditing, consultancy, and field implementation) has been growing, both within the hydrocarbon and the non-hydrocarbon industries. This latest edition is almost a total revamp of the previous one and greatly benefits from the author's continuous learning process through his frequent involvement with various oil and gas sectors and different industries as a corrosion management trainer, auditor, and consultant. Since the latter half of 2015, when he started working as an independent corrosion engineering and corrosion management consultant, he has been increasingly engaged with numerous upstream-, midstream-, and downstream oil and gas assets as well as in various non-hydrocarbon industries. Such continuous encounters have taught him many new valuable lessons and provided him with a much deeper insight into how we often manage our assets' integrity, our strengths and weaknesses, the sometimes very trivial causes of our integrity oversights and mistakes, and so on. He has done his best to reflect all such new learning and improved asset integrity management insight in this book.
