The WSD methodology has been successfully applied largely without change within Europe and worldwide. Proceedings of an international conference Subsea Controls and Data Rp2z ‘ Rock Mechanics Symposium and 5th U.

Application of API RP2A-LRFD to a North Sea Platform Structure – OnePetro

Advanced search Show search help. 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.

The effect on total structure weight and the differing effect on various categories of structural element are summarised. Thomas BP Engineering R.

These aspects assume increasing importance as element design is further refined. The reliability of the Goodwyn ‘A’ substructure has been a major focus of the design and results are presented showing the platform reserve fp2a, computed using non-linear inelastic ductility analyses. The study is based on work performed for Woodside as part of the substructure design for the Goodwyn ‘A’ Platform.

Proceedings of an International Conference Submersible Technology: Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition.

The designation ‘load resistance factor design’ derives from the concept of factoring both loads and resistances as opposed lrvd the working stress design approach where only the resistance is divided by a factor of safety. Proceedings of an international conference Diverless and Deepwater Techology: Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. The issue of a load resistance factor design version reflects the worldwide trend away from working stress design to reliability based methods.

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.

Proceedings of an international conference Subsea Controls and Data Acquisition ‘ However is expected to see the publication of the Load and Resistance Factor Design version as an AP1-approved alternative. Since it rp2x first issued inthe working stress code RP2A Ref 2 has become an internationally accepted standard for fixed platforms. Publishers Content Coverage Privacy.

Partial factors are used to account explicitly for the variance of criteria, and can therefore be calibrated to provide more consistent safety levels.

Proceedings of an international conference Diverless and Deepwater Techology: LRFD however, is an improved approach to structural design which takes into account the possible uncertainties in the applied loads and component resistances.

Proceedings of an International Conference Submersible Technology: This paper does not discuss the very important but less quantifiable concepts of structural redundancy and the ability to redistribute loads from non-performing structural elements.

This is achieved by xpi a basic framework for design, accompanied by guidance on problem areas lying outside this framework. Log in to your subscription Username. 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.
