Hardcover. Condizione: New. 439 pages : illustrations (some colour), maps (some colour) ; 30 cm. This international site investigation conference, organised by the Offshore Site Investigation and Geotechnics (OSIG) Committee of the Society for Underwater Technology, is the fifth in a series started by SUT in 1978. The last quarter of a century has seen dramatic changes in the technologies, areas and water depths in which we work, and the speed with which projects move from conception to implementation. Moving into the 21st century we have seen a new focus on sustainability issues at global and local levels. Sustainability has implications for the natural environment, resource and energy management, and on the economic survival of complete industries, as well as companies and individuals. Engineers and scientists need to focus on new ways of working, increasing their effectiveness and breadth of thinking to ensure that projects meet the triple requirements of economic efficiency, environmental protection and social acceptability. To do this we need to be both more innovative and diverse in our activities. The theme for this fifth conference was, therefore, Diversity and Sustainability with over 30 papers encompassing the widest possible range of geographic, technological and innovative projects.…

Hardcover. 250 pages. Proceedings of an international conference (The Market for Underwater Construction) organized by the Society for Underwater Technology, and held in London, 5 & 6 March 1987. A very good hardcover copy; no dust jacket, as issued. Clean inside. No highlighting or underlining. Falling oil prices and smaller offshore fields, especially in the UK sector of the North Sea, have produced a resurgence of interest in subsea developments. These developments always include the installation of a subsea structure and laying and tying-in of pipeline and control lines. In the Southern North Sea small unmanned jackets may become widely used and these require subsea control and power lines installation. This change in the offshore scene has produced a potentially larger market for underwater construction activities. Companies engaged in underwater design and construction have been developing new equipment and techniques to enable further economies to be realised. It is not only in hydrocarbon development where underwater construction plays a major role. One of the largest offshore construction projects on the UK Continental Shelf in recent years is the cross-channel link where power cables have been laid between the UK and France. This volume looks at the economic outlook and the breadth of underwater construction operations; important developments in techniques and equip- ment are presented together with a discussion of various projects in which they have been successfully used. PART I 1 An overview of subsea construction R. Goodfellow, Goodfellow Associates Ltd INTRODUCTION Working underwater is a lot more difficult than working above water or on land, therefore the incentives to do so must be found in some aspects of project realization, such as: - reduced cost; - advantageous schedule; - improved technology. …

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - The concept of using flexible, reelable pipe to transport liquids, gases, and vapours is not a new one. As early as the 1940s a steel braided elastomeric pipeline was developed for the Allied Forces in order to transport fuels to support the Normandy Beacheads. In fact, the longest flexible pipeline ever constructed is likely to be that laid across the English Channel as part of 'Operation Pluto'. The methodology used to handle and instal such pipe is also not new. Ellis (1943, London) in an early patent specification identifies three basic objectives for a flexible pipelining method. These are: prefabrication of the pipe onshore; coiling of the pipe on suitable drums or reels; and using such reels to lay pipe from anchored or motorised barges. The design concept for flexible pipe is also not a new invention given that flexible hoses and umbilicals have been in service for more than sixty years. A break-through was however achieved by the French Institute of Petroleum in the early 1970s when they developed an improved steel reinforced pipe structure having a high axial loading capaci ty which utilised corrosion and hydrocarbon resistant polymers to extend pipe service lifetime. This early pipe design utilised established cable making techniques to apply steel armour and axially and radially reinforce alternating layers of polymer sheaths. The pipe was primarily developed as a flowline for use in static seabed applications.…
