c. P. Wroth, Oxford University, UK I am grateful to the Organising Committee that were covered on the first day. First, we for the invitation to attempt to sum up the had Dr Riemersma talking about positioning proceedings. Summing up is not really the requirements, and it seemed to me to be an appropriate phrase - it is a difficult job to unhappy reflection on human frailty that he do justice in a summary to the amount of was concentrating so ...

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 maintain quality in research output, providing the necessary new knowledge for our developing industries must be of prime importance to our community. This is an extremely difficult task when viewed in the context ofthe rapid rate of change being experienced within our national industrial scene. Collaborative research programmes designed to constantly monitor and improve the quality of output, through regular reporting and assessment of ach...

The biennial conferences of the Society for Underwater Technology have achieved an excellent reputation for the quality of their presentations, which cover topics of the most acute current interest, as well as those at the forefront of review and development. The 1994 conference on Subsea Control and Data Acquisition formed no exception, since it covers subjects at the cutting edge of modern technology. It is a matter of increasing concern tha...

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 ...

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 ...

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 enhanc...

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...

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...

Proceedings of an international conference (Subsea International DEGREES89) held in London, UK. Subsea production systems are now accepted by the industry and are indispensable for developing small satellite fields in particular. The second generation emphasis is on extending the horizontal distance
