Reliability based inspection scheduling for fixed offshore structures
report
In order to ensure the structural integrity of offshore structures, it is necessary to carry out periodic inspections. Fatigue cracking is one of the main deterioration processes and the inspection for cracks in welded joints forms a significant part of the inspection effort. Recent developments in structural reliability theory, fatigue fracture mechanics and the availability of various probabilistic databases such as corrosion fatigue data, inspection reliability data can be used to provide a theoretical framework for inspection planning. In addition, advances in knowledge based system technology allows the incorporation of practical constraints with the theoretical results to provide an integrated practical solution. This paper describes the develOpment of a knowledge based system incorporating the latest reliability based inspection planning methods. This development is the result of a large EC funded project under the THERMIE initiative and has had technical input from several organisatiorts in four European countries.
