This book came about because my son, who had just started his MSc in Offshore Engineering at Cranfield University, said to me that since I supposedly knew a fair bit about Asset Integrity Management, I should write a book on it. As I’d previously written several books on diving and dive watches, I thought; “hey, now that’s not a bad idea.” What you have here is a collection of information dealing with what I consider to be the most important aspects of Asset Integrity Management. Some of it is based on papers and articles I have written, but considerably more is unashamedly “blagged” from many other sources that I consider to be far more knowledgeable than me on the subject matter. It really started out as an attempt to put “old heads on young shoulders” and grew from that. I hope that you find it educational, enlightening and thought provoking and that it helps you understand Asset Integrity Management better.
