CALIBRATION OF THE DRAFT RP2A-LRFD FOR FIXED PLATFORMS

A research program and API committee activity underway since 1979 have produced the draft "Recommended LRFD Practice for Planning, Designing, and Constructing Fixed Offshore Platforms, API RP2A-LRFD". A companion paper by Lloyd and Karsan (1988) presents the history, objectives, and benefits of this draft Recommended Practice (RP), the first from API to have a thorough reliability basis. This paper explains the reliability calibration of the principal safety factors.
