The study is based on work performed for Woodside as part of the substructure design for the Goodwyn ‘A’ Platform. The reliability of the Goodwyn ‘A’ substructure has been a major focus of lrfs design and results are presented showing the platform reserve capacity, computed using non-linear inelastic ductility analyses.

lrfdd This is achieved by providing a basic framework for design, accompanied by guidance on problem areas lying outside this framework. 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: Advanced search Show search help. Although fundamental differences exist between the WSD and LRFD versions, the two documents remain remarkably similar with the LRFD draft containing most of the apo phrased clauses which are familiar to many practicing engineers.
Offshore Technology Conference Disciplines 4. As a reliability based alternative, the load lffd 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
Proceedings of an international conference Diverless and Deepwater Techology: Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. Proceedings of an International Conference Submersible Technology: Peer reviewed only Published between: The work is confined to the in-place strength of the jacket and module support frame MSF.
Proceedings of an international conference Subsea Controls and Data Acquisition ‘ 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.
LRFD however, is an improved approach to structural design which takes into account the possible uncertainties in the applied loads and component resistances.
Since it was first issued inthe working stress code RP2A Ref 2 has become an internationally accepted standard for fixed platforms.
