The main aim of this thesis is to develop a probabilistic methodology, based on structural reliability theory, which allows information gained during manufacture, fabrication, construction and service life of a particular structural system to be systematically combined with data available at the design stage in order to improve reliability predictions about the structure's performance during its remaining service life. Broadly speaking, the objectives of the thesis can be summarised as follows: • To develop generic strategies and methods for reliability-based structural integrity assessments focussing on specific structures or plant • To further develop reliability-updating procedures so as to sharpen predictions of remaining life • To determine the value of obtaining additional in-service data in terms of improved SI calculations and reduction of model uncertainty. To achieve these objectives, consideration is restricted to two factors affecting the SI of offshore steel jacket structures, namely fatigue crack growth and system reliability performance under the influence of environmental loading.
