Briefly, the book is intended to provide a comprehensive overview of all techniques that are available in the industry for joining/repair offshore structures. Joining systems not involving the use of welding are discussed first. These engineering systems required for joining procedures are then discussed - pipe handling, design of the hyperbaric chambers etc.
The principal techniques of the underwater welding are then described - wet, one atmosphere plus hyperbaric welding, followed by a clear description of the major effects of environmental pressure on the hyperbaric welding processes. To make this section of the book more comprehensible to the general reader, a brief description of each welding process as it is used in general engineering is included before the modifications required for hyperbaric applications are discussed. Finally, those joining systems not used currently, but which show promise in the lab, are described, followed by some speculation relating to how underwater joining technology might develop over the next few years.
For general information, appendices providing description of the relevant diving technology, basic oceanography and also the methods of research commonly applied for the development of hyperbaric welding techniques are included. Although this book describes the technology of underwater repair at all water depths, it should be recognized that the great majority of offshore repair work is carried out at relatively shallow depths, in the region intermittently covered by the water, known as the "splash zone". This is because the speed of any object dropped from the platform or an adjacent ship is highest at the water line, while wave loadings, corrosion activity and the growth rate of marine life arc all at a maximum just below the surface.
In addition, the possibility of collision between shipping and the platform is also maximized at shallow depths. Thus, numerically, the majority of underwater repairs takes place at shallow depths, although the most economically and technologically significant arc in deeper water, frequently on pipelines.

All fundamental design principles have been illustrated by the informative sketches. The extensive use of images is one of the particular features of the volume clarifying the ambiguities...
The readers involved in steel design and construction have appreciated the content of this informative title and have found it simply excellent. The publication was worked out by William Segui giving students and professionals all required knowledge that is covering the critical aspects of the steel design process with the particular emphasis made on the design steel members together with their connections.
Segui has designed this book in such manner that would allow the instructors to teach ASD, LRFD (or both), bearing in mind that there is only minor conceptual difference between them. He has made a very good job attempting to simplify the complex topics plus design procedures. This is definitely a best option for the persons who want to study the underlying theoretical principles plus the fundamental mechanics of the steel members.
All complicated topics have been clearly explained and the author made them quite easy to be understood even for the persons without any specific background or professional experience. Talking about clarity, there is no any other textbook that could be comparable to "Steel Design". We do recommend this volume to a broad audience since the explanations of various theoretical topics have been presented in a very accessible manner. The theoretical chapters are supplemented with many examples all of which, in turn, are thoroughly explained.
The welding itself is treated as a technical skill of constantly increasing demand; in fact, we may say that the theoretical basics of welding could quite easily be learned by all students. The author of the present welding textbook has more than four decades of professional experience in welding; the publication reflects the results of his efforts setting out the fundamental techniques related to the different types of welding including arc welding, oxy-acetylene welding, as well as brazing and others.
This is an excellent choice for the newbie welders willing to get a proper and thorough understanding of the basics of welding and get familiarized with the most commonly used welding techniques, processes plus the equipment used. This is a handy reference work explaining the main welding processes as they have been developed, introduced and subsequently used in the industry. The application of the welding to model engineering has also been addressed in the present volume.
The main content of the textbook is divided into two halves supplemented with three appendices providing the information about the weld symbols, frequent welding defects and aids to assembly. This book also covers the exercises with mild steel, resistance welding, welding of pipes, MIG/TIG welding together with many other important technical aspects directly related to the welding.
The content of this book has been found to be perfectly written with particular attention paid by its author to the technical details that would help in making the training process go smoother. The chapters of the paper are arranged in such manner that keeps an order to the major steps that shall be taken for better earning results. There is a separate chapter dedicated to the metallurgy.
The book provides great information about the pipe welding in both 2G/3G welding positions, giving a wealth of practical tips and data diagrams, together with the guidelines on how to establish a good pipe weld. The readers will definitely have much better understanding o controlling of the arc, importance of proper fit-up and welding itself. The information will be greatly appreciated by the students; and the professional welders will noticeably increase the quality of their welds.
The author has provided very understandable and clear explanations supplemented with numerous informative pictures. The content is intended to serve as the useful reference source for refreshing the steps and procedures. The newcomers to the field will also find this volume useful. The book has been serving as a pretty standard reference volume for several decades. This latest released is continuing to enforce the proper technical understanding of the welding procedures...
The publication is presenting the updated view of the marine corrosion of the stainless steel, covering the relevant fields of selection and testing of the materials, their protection and monitoring. The first part of the volume consists of five chapters and is mainly concerned with the analysis of the results of the tests conducted in the course of the researches performed in the European sea waters towards the three popular types of the stainless steel some thirty years ago.
The author of the book has provided the clear description of the experimental procedures and all required data, such as the critical pitting temperature, as well as the crevice corrosion results etc. This information is forming the core of the volume, followed by the chapters dealing with the professional reviews of the results and reports. The main covered topics are the selection of the materials, including superaustenic steels, desalination processes, high-alloy steels, topside marine corrosion, duplex stainless steels and other important matters.
The chapter addressing the testing and experience covers the application limits, steel ageing and its influence on the behavior, modern steels, potential-dimension diagram, nickel base alloys etc. The "protection and monitoring" chapter covers the cathodic protection, monitoring of the pitting corrosion, future applications and other aspects.
The preparation of the content of this third release of the Handbook nearly ten years after the release of the original one, required a full revision of the major portion of the book, not only because of the recent technical developments that occurred in technology and application, but also because of the identification of the critical factors in the protection systems.
The authors has also taken into account the developments in the recognized standards and commonly applicable regulations. The electro-chemical corrosion and associated corrosion protection are based on the same foundation. The scientific basis of the present volume has been formed by the uniform terminology provided in the DIN 219 manual. Our understanding of the problem has been significantly improved thanks to the descriptions of the newly developed systems of protection and questions related to the utilization of the current and potential distribution plus the influence of the high tension.
There are some serious advances in the IR-free potential measurement, data evaluation and intensive measuring techniques. The publication is highly recommended to the people dealing with the prevention of corrosion of the ship hulls, i.e. workers of the ship construction and repair industries who will definitely appreciate the content of the volume.
