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

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

The WSD methodology has been successfully applied largely without change within Europe and worldwide. 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. 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.

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.

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. Proceedings of an international conference Subsea Controls and Data Acquisition ‘ Proceedings of an international conference Oceanology: Proceedings of an international conference Diverless and Deepwater Techology: 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.

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. 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. Rock Mechanics Symposium and 5th U.

The work is confined to the in-place strength of the jacket and module support frame MSF. However is expected to see the publication of the Load and Resistance Factor Design version as an AP1-approved alternative.

Proceedings of an International Conference Submersible Technology: Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. Since it apl first issued inthe working stress code RP2A Ref 2 has become an internationally accepted standard for fixed platforms. These aspects assume increasing importance as element design is further refined.

The effect on total structure weight and the differing effect on various categories of structural element are summarised. Rock Mechanics Symposium and 5th U. Its use in Europe is supplemented by additional local regulatory requirements and performance criteria but the designmethodology, basic code checking equation sand safety levels for rp2 strength are primarily related to API RP2A.

Peer reviewed only Published between: This is achieved by providing a basic framework for design, accompanied by guidance on problem areas lying outside this framework.
