But with the introduction of the LRFD methodology it has become possible to rationally account for the variance between US regional conditions and other localities.
Application of API RP2A-LRFD to a North Sea Platform Structure – OnePetro
Proceedings of an international conference Diverless and Deepwater Techology: This paper also discusses the different partial load factors applicable to gravity loads when improved accuracy of weight control is effected, and applicable to environmental load when yearor year return period extreme environmental criteria are used in the North Sea. Rock Mechanics Symposium and 5th U. The designation ‘load resistance factor design’ derives from the concept of factoring both loads and resistances as opposed to the working stress design approach where only the resistance is divided by a factor of safety.

As a reliability based alternative, the load resistance factor design LRFD method offers a more consistent approach to platform safety than does the existing RP2A working stress design WSD method. Offshore Technology Conference Disciplines 4. The WSD methodology has been successfully applied largely without rpa2 within Europe and worldwide.
Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. This is achieved by providing a basic framework for design, lrcd by guidance on problem areas lying outside this framework.
Publishers Content Coverage Privacy. Rp22a however, is an improved approach to structural design which takes into account the possible uncertainties in the applied loads and component resistances. The issue of a load resistance factor design version reflects the worldwide trend away from working stress design to reliability based methods.
The reliability of the Goodwyn ‘A’ substructure has been a major focus of the design and results are presented showing the platform reserve capacity, computed using non-linear inelastic ductility analyses.
Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. These aspects assume increasing importance as element design is further refined. Peer reviewed only Published between: To conclude, this paper makes the connection between the work reported here and the international effort to develop an ISO Standard for offshore structures, in which partial factors appropriate to regional conditions will feature.
