Derive load and resistance factors that provide a level of safety close to current practice WSD 12th edition for each component design check.

Design requirements for fixed offshore platforms by Chevron.

Three sections were removed i. Although fundamental differences exist between the WSD and Lrfr 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. Lrffd Mechanics Symposium and 5th U. Hamonization in safety levels requires location-dependent partial action factors.

Proceedings of an international conference Oceanology: The study is based on work performed for Woodside as part of the substructure design for the Goodwyn ‘A’ Platform. The project will start in early and last for two years.

Recommended practice for planning, designing and constructing fixed offshore platforms – load and resistance factor design: Its use in Europe is supplemented by additional local regulatory requirements and performance criteria but the designmethodology, basic code checking equation sand safety levels for ultimate strength are primarily related to Wpi RP2A.

LRFD in later editions of this AISC specification are based on calibration with building design practices and may not be applicable to offshore platforms.

I searched around myself but didnt find that. This new interaction equation provides a better fit to the available test data than does the arc sine expression in the 21st edition.

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.


Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Recommended practice for planning, designing and constructing fixed offshore platforms – load and resistance factor design. To conclude, this paper makes the connection between the work reported here and the international effort to develop an ISO Standard for offshore structures, in which partial factors appropriate to regional conditions will feature.

A Comparative Study Using API RP2A-LRFD – OnePetro

Partial prfd are used to account explicitly for the variance of criteria, and can therefore be calibrated to provide more consistent safety levels. Peer reviewed only Published between: However is expected to see the publication of the Load and Resistance Factor Design version as an AP1-approved alternative.
