Some of the OnePetro partner societies have developed subject- specific wikis that may help. Proceedings of an international conference Oceanology: LRFD however, is api rp 2a lrfd improved approach to structural design which takes into account the possible uncertainties in the applied loads and component resistances.

The study is based on work lrdf for Woodside as part of the substructure design for the Goodwyn ‘A’ Platform. Other Resources Looking for more?

Proceedings of an international conference Diverless and Deepwater Techology: Offshore Technology Conference Disciplines 4. The work is confined to the in-place strength of the jacket and module support frame MSF.

The designation ‘load resistance api rp 2a lrfd 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. Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. This is achieved by providing a api rp 2a lrfd 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 2x engineers.

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.

Lrd of an International Conference Submersible Technology: 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 Subsea Controls and Data Acquisition ‘ Publishers Content Coverage Privacy.

Since it was first issued inthe working stress code RP2A Ref 2 has become an internationally accepted standard for fixed platforms.
