Proceedings of an international conference Oceanology: 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.

A Comparative Study Using API RP2A-LRFD – OnePetro
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 krfd.
The work is confined to the in-place strength of the jacket api rp 2a lrfd module support frame MSF.
This is achieved by providing a basic framework for design, accompanied by guidance on problem areas lying outside this framework. Log in to your subscription Username.
Proceedings of an International Conference Api rp 2a lrfd Technology: 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.

LRFD however, is an improved approach to structural design which takes into account the possible uncertainties in the applied loads and component resistances. Api rp 2a lrfd issue of a load resistance factor design version reflects the worldwide trend 2 from working stress design to reliability based methods.
Api rp 2a lrfd it was first issued inthe working stress code RP2A Ref 2 has become an internationally accepted standard for fixed platforms. 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 study is based on work performed for Woodside as part of the substructure design for the Goodwyn ‘A’ Platform.
