The conference, organized jointly by the International Association of Underwater Engineering Contractors and the Society for Underwater Technology, was held in November 1989. The three sessions cover changing requirements for underwater inspection and maintenance; developments in remotely controlled technology; and advances in diving safety. No index.

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.
Edited by the Society for Underwater Technology, this text covers advances in subsea pipeline engineering and technology. Topics covered include changes in the industry, high pressure/high temperature, design, construction/installation and operations and maintenance.
Aspect '94 is the most up-to-date and comprehensive assessment of the present and future of the pipeline systems industry. It comprises papers from leading experts in all areas of pipeline engineering and technology. As this book shows, the last few years have seen great strides forward in the field of subsea pipelines. Deepwater pipelines, long distance pipelines and complex systems transporting hydrocarbons and fluids to and from marginal field subsea wellheads and templates are all being implemented without significant problems. The pace of progress continues to accelerate in the subsea industry, and the scope to make further improvements is constantly being explored. Operators, consultants, suppliers and contractors are all researching, developing and testing new techniques and ideas.
The three parts of this volume - Technical Refinement; Technical Innovation; and Project Management and Risk Minimisation - reflect the areas of opportunity for improved cost effective techniques for exploration and production of oil and gas in the North Sea and worldwide. The book is indispensable for engineers and scientists interested in the latest advances in technology and resource management that will reduce costs and continue to enhance the safe exploration of oil and gas resources. This volume comprises a selection of contributions presented at the International Conference Subsea International '93, held 28--29 April 1993 in Aberdeen, U.K.
In determining the response of offshore structures, it is of utmost importance to determine, in the most correct manner, all factors which contribute to the total force acting on these structures. Applying the Morison formula (Morison et. al. , 1950) to calculate forces on offshore slender structures, uncertainties related to the understanding of the wave climate, the hydrodynamic force coefficients and the kinematics of ocean waves represent the most important contributions to the uncertainties in the prediction of the total forces on these structures (Haver and Gudmestad, 1992). Traditional calculation of forces on offshore structures involves the use of regular waves with the following non-linearities inco1porated use of regular wave theories inco1porating higher order terms use of Morison equation having a nonlinear drag term inclusion of the effect of the free surface by integrating all contributions to total forces and moments from the sea floor to the free surface of the waves In order to describe the sea more realistically, the ocean surface is to be described as an irregular sea surface represented by its energy spectrum. The associated decomposition of the sea surface is given as a linear sum of linear waves. The total force is found by integrating the contribution from all components in the wave spectrum to the free surface. The kinematics of each component must therefore be determined.

SUBTECH '93 features subjects as varied as contracting strategies through to hearing loss in divers. The latest developments in underwater intervention technology include presentation on remotely operated vehicles, manned submersible operations and a record-breaking simulated deep dive. Medical and physical areas of diving operations are addressed, together with operational and safety aspects. This, the sixth in the series of the jointly organised events by AODC/SUT, brings topicality, safety and economic issues to the forefront.
High pressure biology is an old, fascinating and stimulating field of research. One of the major reasons for the interest in studying high pressure is that this environmental factor also plays an important role in thermodynamics and consequently in biology. Pressure, from a biological perspective, has a bearing on all living creatures. The book pre
First published in 1981 as the Offshore Information Guide this guide to information sources has been hailed internationally as an indispensable handbook for the oil, gas and marine industries.
