RELIABILITY-BASED FATIGUE INSPECTION PLANNING
OF FIXED OFFSHORE STRUCTURES

Abstract
-This paper proposes the practical application of a reliability-based
procedure for fatigue inspection planning of fixed offshore structures. This
procedure is based on a simplified probabilistic crack growth model for welded
tubular joints available in the literature, which encompasses fracture mechanics
and S-N curves and uses the results of the original fatigue design. Current
techniques for reliability updating are implemented to re-evaluate the fatigue
failure probability after inspection campaigns. Target reliability values are
defined to be compatible with the simplicity of the procedure. Actual
applications illustrate the inspection costs reduction that can be obtained.
