EFFECT OF DESIGN, FABRICATION, AND INSTALLATION ON THE STRUCTURAL RELIABILITY OF OFFSHORE PLATFORMS

This paper emphasizes the concept of "as-built" reliability vs "as-designed" reliability related to fixed offshore platforms. After an offshore platform is initially designed in accordance with criteria based on probabilistic concepts, modifications may be introduced which can affect its intended structural reliability. These modifications can occur during the various phases of design, fabrication, and installation. Several examples of such changes are cited. A brief outline of one approach to computing a platform's probability of failure is also presented and a computational example is included to illlustrate the methodology of comparing the as-built reliability with the as-designed reliability.
