STATE OF THE ART: BEHAVIOUR OF (OFFSHORE) STRUCTURES AND STRUCTURAL DESIGN

Some general information on Det norske Veritas involvement in oil and gas exploitation in the North Sea and elswhere, and a brief survey of the Society's recent activities relating to the design and construction of offshore structures, are followed by a discussion in which three categories--static, dynamic, and enduring--of the behaviour of such structures are considered. Design principles are then discussed. DnV places much emphasis on continuous and critical revisions of design rules and methods of analysis. The semi-probabilistic (or limit-state) design method is the main method used for both steel and concrete structures, but a genuine probabilistic method is allowed if realistic and sufficient statistical data are available. The principles of both these design methods are briefly explained. Methods of behaviour analysis, including deterministic and stochastic analyses and fatigue analysis, are also discussed and explained. In a final section of the article, general reliability is considered and brief information is given on a special project, now being carried out by DnV, on the reliability and operational safety of offshore units. The principal aim of this project is the establishment of a data bank for various types of mishap and accident causing pollution, personal injuries, and serious damage, so that statistical risk analysis can be carried out for both future and existing structures.
