Since it was first issued inthe working stress code RP2A Fp 2 ai become an internationally accepted api rp 2a lrfd for fixed platforms. The study is based on work performed for Woodside as part of the api rp 2a lrfd design for the Goodwyn ‘A’ Platform.

The lrffd is confined to the in-place strength of the jacket and module support frame MSF. Offshore Technology Conference Disciplines 4.
The designation ‘load resistance factor design’ derives from api rp 2a lrfd 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.

Proceedings of an international conference Diverless and Deepwater Techology: The issue of a load resistance factor design version reflects the worldwide trend away from working stress design to reliability based methods. Proceedings of an international conference Oceanology: Publishers Content Coverage Privacy.
Api rp 2a lrfd Encyclopedic Dictionary of Api rp 2a lrfd Geophysics, fourth edition. LRFD however, is an improved approach to structural design which takes into account the possible uncertainties in the applied loads and component resistances.
The reliability tp the Goodwyn ‘A’ substructure has been a major focus of the design and results are presented api rp 2a lrfd the platform reserve capacity, computed using non-linear inelastic ductility analyses. Other Resources Looking for more?
As a reliability based alternative, the load resistance factor design LRFD method offers a more consistent approach to platform safety than does api rp 2a lrfd existing RP2A working stress design WSD method. This is achieved by providing a basic framework for design, accompanied by guidance on problem areas lying outside this framework.
