The book "Reliability of Ship Power Plants" by O. R. Smirnova is a deep and comprehensive study that immerses the reader in the world of marine energy. In the conditions of modern shipbuilding and operation of ships, the issues of reliability of energy systems are becoming increasingly relevant. Smirnov, possessing rich experience and knowledge in this area, offers the reader not just theoretical calculations, but practical recommendations and analysis of real situations, which makes his work indispensable for specialists and students interested in marine engineering. The book covers a wide range of topics related to the design, operation and maintenance of marine power plants. It examines the main factors affecting the reliability of these systems, as well as methods for assessing and improving their effectiveness. Smirnov focuses on the importance of preventive maintenance, the introduction of modern technologies and monitoring systems, which allows not only to extend the service life of equipment, but also to significantly reduce the risks of accidents on board the ship. This work will be especially interesting for students of technical universities, graduate students and young professionals seeking to deepen their knowledge in the field of shipbuilding and marine energy. The book will also be useful to practicing engineers working in shipbuilding and ship repair companies, as well as in organizations engaged in the operation of maritime transport. Readers interested in the topics of reliability, safety and innovation in energy systems will find in it a lot of useful ideas and recommendations. One of the key themes of the book is the influence of the human factor on the reliability of power plants. Smirnov emphasizes that even the most modern technologies can not guarantee trouble-free operation if the staff is not trained and is not aware of the possible risks. This makes the book relevant not only for engineers, but also for managers responsible for training and training . The author's style is distinguished by clarity and accessibility, which makes it easy to assimilate even the most complex concepts. Smirnov uses many examples from practice, which makes the material lively and interesting. His previous works, such as “Modern Technologies in Shipbuilding” and “Energy Systems of Maritime Transport”, have also received recognition for their practical focus and in-depth analysis. The book “Reliability of Ship Power Plants” is not just a textbook, but a real reference book for anyone who wants to understand the intricacies of ship power systems. It raises important questions regarding maritime safety and offers the reader not only theoretical knowledge but also practical skills that can be applied in real life. If you are looking for literature that will help you better understand how ship power plants work and how to ensure their reliability, then this book will be a real discovery for you. It will become a reliable assistant in your professional activities and a source of inspiration for new ideas and solutions. Do not miss the opportunity to immerse yourself in the world of marine energy with O. R. Smirnov and his fascinating work!
