Query: Excellent book

I am an engineer working on the design and analysis of offshore structures and risers. Recently I read through this book and was totally impressed by the clarity of its writing. Also, there are lots of informative figures that help me understand how offshore drilling is done. After reading it, I feel that I have a much more comprehensive knowledge about offshore drilling operation. This book deserves a 5-star rating.
