Enhancement of inspection and maintenance of industrial structures using reliability based methods and expert systems

A database used for the reliability calculation and for the knowledge based system (KBS) was assembled. An original method, capable of handling time variant reliability problems, was then implemented numerically, and on optimisation module taking into account new information and data on inspection costs was created. It yields an inspection plan for a given element. The method and numerical tool was successfully tested and RAMINO was designed.
RAMINO provides a rational frame for the collected data and the numerical methods developed, complemented with the knowledge obtained from elicitations of field experts and from the collection of non numerical data.
Since the end of the project, partial results were used to develop IMREL (Inspection and Maintenance using Reliability) which was merged with the DGXVII THERMIE project RISC (Reliability Based Inspection Scheduling for fixed offshore platforms). These softwares are marketed by TSC in the United Kingdom and RCP in Muenich.
