Underwater Technology: Offshore Petroleum covers the proceedings of the Underwater Technology Conference. The book discusses the development of safe and economic underwater operations and systems for underwater petroleum production. The text is comprised of 20 chapters, which are divided into four parts according to the areas of concern they tackle. Part 1 concerns itself with subsea production systems, and Part 2 tackles the operations system. Part 3 covers topics relating to inspection, reliability, and control, while Part 4 discusses testing. The book will be of great interest to professionals and researchers concerned with the development of underwater petroleum production.

The oceans are a hostile environment, and gathering information on deep-sea life and the seabed is incredibly difficult. Autonomous underwater vehicles are robot submarines that are revolutionizing the way in which researchers and industry obtain data. Advances in technology have resulted in capable vehicles that have made new discoveries on how th

The book provides an comprehensive overview of the techniques available for the joining and repair of offshore structures. Nixon starts with joining systems that do not require welding and then explores the associated engineering systems needed for joining procedures. Topics include pipe handling, hyperbaric chamber design, and principal underwater welding techniques, including wet, one atmosphere, and hyperbaric. Nixon also includes a description of the effects of environmental pressure on the various hyperbaric welding processes. A complete guide to underwater welding, this book also discusses technologies that show promise in the laboratory, but are not currently in use. Nixon provides appendices describing the relevant diving technologies, basic oceanography, and the research methods used in the development of hyperbaric welding.

The United States faces decisions requiring information about the oceans in vastly expanded scales of time and space and from oceanic sectors not accessible with the suite of tools now used by scientists and engineers. Advances in guidance and control, communications, sensors, and other technologies for undersea vehicles can provide an opportunity to understand the oceans' influence on the energy and chemical balance that sustains humankind and to manage and deliver resources from and beneath the sea. This book assesses the state of undersea vehicle technology and opportunities for vehicle applications in science and industry. It provides guidance about vehicle subsystem development priorities and describes how national research can be focused most effectively.

This book, now at the third edition, addresses the main control aspects in underwater manipulation tasks. The mathematical model with significant impact on the control strategy is discussed. The problem of controlling a 6-degrees-of-freedoms autonomous underwater vehicle is deeply investigated and a survey of fault detection/tolerant strategies for unmanned underwater vehicles is provided. Inverse kinematics, dynamic and interaction control for underwater vehicle-manipulator systems are then discussed. The code used to generate most of the numerical simulations is made available and briefly discussed.

Underwater wireless sensor networks (UWSN) are envisioned as an aquatic medium for a variety of applications including oceanographic data collection, disaster management or prevention, assisted navigation, attack protection, and pollution monitoring. Similar to terrestrial wireless sensor networks (WSN), UWSNs consist of sensor nodes that collect the information and pass it to a base station; however, researchers have to face many challenges in executing the network in an aquatic medium. Energy-Efficient Underwater Wireless Communications and Networking is a crucial reference source that covers existing and future possibilities of the area as well as the current challenges presented in the implementation of underwater sensor networks. While highlighting topics such as digital signal processing, underwater localization, and acoustic channel modeling, this publication is ideally designed for machine learning experts, IT specialists, government agencies, oceanic engineers, communication experts, researchers, academicians, students, and environmental agencies concerned with optimized data flow in communication network, securing assets, and mitigating security attacks.

Up to about 30 years' ago diving activity was centred primarily on the naval services, who provided a lead in the development of equipment, techniques and procedures. Apart from one or two spectacular salvage undertakings, the main commercial activity up until that time was fairly low-key work in docks and harbours. The concept of saturation diving emerged from subsea habitats of which Captain Cousteau was one of the pioneers. This led the way to commercial development in support of exploration and the production of offshore oil and gas, and I believe that my friend Henri Delauze was one of the first to mount the subsea habitat on deck and provide a sealed bell to convey divers from the habitat to the seabed without change of pressure. A remarkable feature of offshore oil and gas technology in the North Sea has been the willingness of all concerned to exchange information regarding R&D. This has had a major effect on the advance in technology over the last few years. As far as diving is concerned, it is to some extent 'Hobson's Choice'. Legal patents are difficult to achieve in this field, and the casual nature of diver employment to date has meant that ideas and techniques circulate almost as freely as the divers themselves. In addition, the advertis ing of the new technologies which one has to offer almost auto matically means disclosure of what otherwise might be secret.
