Technical progress in pipeline design and construction.

摘要

This paper considers the technical progress in offshore pipeline construction with limitation to some general subjects covering pipeline design, installation and start-up. In future the use of limit state pipeline design philosophy, may be implemented as an alternative to the stress based design commonly used to day giving a potential for further optimisation of the pipeline design and consequently reduction of the initial investment. Comprehensive research and development efforts in Norway in the second half of the 1970's, made it technically feasible to cross the deep water Norwegian Trench in the 1980's. In addition, the development of several offshore pipeline systems until to day including gas distribution systems to the European continent, have brought Norway to the forefront of technical expertise
