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. The issue of a load resistance factor design version reflects the worldwide trend away from working appi design to reliability based methods.
Since it was first issued inthe working stress code RP2A Ref 2 r2pa become an internationally accepted standard for fixed platforms. Rock Mechanics Symposium and 5th U.
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. This is achieved by providing a basic framework for design, accompanied by guidance on problem areas lying outside this framework.

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.

API RP2A – LRFD
Apk 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 Oceanology: Publishers Content Coverage Privacy. Proceedings of an international conference Diverless and Deepwater Techology: Proceedings of an international conference Subsea Controls and Data Acquisition ‘ The designation ‘load resistance factor design’ derives fp2a 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.
