Rock Mechanics Symposium and 5th U.
This is achieved by providing a basic framework for design, accompanied by guidance on problem areas lying outside this framework. The reliability of the Goodwyn ‘A’ substructure has been a major focus of the design and results are presented showing the platform reserve capacity, a2 using api rp 2a lrfd inelastic ductility analyses.

Although fundamental differences exist between the WSD and LRFD versions, the two documents remain remarkably similar with the LRFD draft containing most 2w the carefully phrased clauses which are familiar to many practicing engineers.
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.

Some of the OnePetro partner societies have developed subject- specific wikis that may help. The work is confined to the in-place strength of the jacket and module support frame MSF.

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 api rp 2a lrfd 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.
