Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. This is achieved by providing a basic framework for design, accompanied by guidance on problem areas lying outside this framework.

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 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.

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.

The work is confined to the in-place strength of the jacket and module support frame MSF. Rock Mechanics Symposium and 5th U. Proceedings of an International Conference Submersible Technology: The study is based on work performed for Woodside as part of the substructure design for the Goodwyn ‘A’ Platform.

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 ultimate strength are primarily related to API RP2A.

Proceedings of an International Conference Submersible Technology: But with the introduction of the LRFD methodology it has become possible to rationally account for the variance between US regional rlfd and other localities.

Although fundamental differences exist between the WSD and LRFD versions, the two documents remain remarkably similar with the LRFD draft containing most of the carefully phrased clauses which are familiar to many practicing engineers.

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. These aspects assume increasing importance as rlfd design is further refined. Proceedings of an international conference Oceanology: Offshore Technology Conference Disciplines 4.

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. However is expected to see the publication of the Load and Resistance Factor Design version as an AP1-approved alternative.

Peer reviewed only Published between: The effect on total structure weight and the differing effect on various categories of structural element are summarised. 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.

Since it was first issued inthe working stress code RP2A Ref 2 has become an internationally accepted standard for fixed platforms. Proceedings of an international conference Oceanology: The WSD methodology has been successfully applied largely without change within Europe and worldwide.
