The reliability of the Goodwyn ‘A’ substructure has been a major focus of the design and results are rrp showing the platform reserve capacity, computed using non-linear inelastic ductility analyses.
The designation ‘load resistance factor design’ derives from the concept of factoring both loads and resistances as opposed to the working stress api rp 2a lrfd approach where only the resistance is divided by a factor of safety. Publishers Content Coverage Privacy.
The work is confined to the in-place strength of the jacket and module support frame MSF. Some of the OnePetro partner societies have developed subject- specific wikis that may help.

Proceedings of an international conference Oceanology: This is achieved by providing a basic framework for design, accompanied by guidance on problem areas lying outside this framework. 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.
The study is based on work performed for Woodside as part of the substructure design api rp 2a lrfd 2w Goodwyn ‘A’ Platform.

Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition. 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 api rp 2a lrfd are familiar to many practicing engineers.
Rock Mechanics Symposium and 5th U. LRFD however, is an improved approach to structural design which takes into account the possible uncertainties in the applied loads and component resistances.
