Michael Hancoxs Oilfield Seamanship series of books (see also pages 26 and 27) have become the focal point for everyone with an interest in modern practical seamanship as it applies to the marine oil industry. This new book, the first ever to look at this complex subject is, in effect, the Towmasters Handbook. Its uses Captain Hancoxs considerable towing and installation experience amassed on projects like Liuhua, Acquila, Maui B, Crawford, Brent, Tantawan, Chanterelle, Janice, Fornaven and many more, to bring the planning, execution and techniques necessary for success to life. His down to earth nautical writing style supported by over 300 explanatory diagrams, hundreds of action on the job photographs, countless examples and tables takes the reader through, in 600 pages, every phase of the operation from pre-tow out planning to riser hook-up and first oil. At every stage Captain Hancox provides helpful tips and cautions to help overcome the problems that lie in wait to trap the inexperienced or unwary. Detailed below are some of the main chapter headings which can at best only provide a limited insight into the massive significance of this outstanding reference work. We would be happy to send the full contents list on request for you to make a fuller evaluation but rest assured that if you are involved in any aspect of towing positioning or hook-up for offshore production, this new book from Michael Hancox will be essential reading.
