The book about the offshore oil business and other components of this type of activity is written in an easy to read literary genre. It is intended for a wide range of readers and will be of interest primarily to students and university students. The book will also be of interest to oil companies that already have a segment of the marine oil business (ship bunkering) or are just planning to create one. It is also attractive for ordinary private oil business entrepreneurs who are expanding their scope of activity. Everything is taken from real life based on the personal experience of the author of the book, from organizing wholesale sales of petroleum products to the most complex sea bunkering and construction of port oil terminals.
