Information database on pipeline materials, flaw assessment procedures, NDT methods in CCE-NIS countries; Knowledge Based System (as a programme package) for defect and failure mode analysis and preventive maintenance.
Failures found in transit oil and gas pipelines pose major safety, economic and environmental problems and accordingly require reliable accident prevention, repair and maintenance procedures. These issues have received inadequate attention in CCE/NIS countries, though two of the partners, Hungarian Oil and Gas Co. and Transneftediagnostika currently operate separate Knowledge Based Systems (KBS) in Hungary, Belarus, Ukraine and Russia to monitor and manage the large (610 - 1230 mm diameter) pipelines. The development of an advanced multilingual KBS for pipeline management incorporating Geographical, Material and Conditions of Loading Databases (with the ability to convert data to/from existing databases) is the aim of the project. Case studies will play an important role in defining damage processes and permissible damage criteria, as many of the existing transit CCE/NIS pipelines, which also link Russia with Western Europe, are up to 30 years old. Research Institutes in Hungary (Bay Zoltan), Ukraine (Problems of Strength) and Bulgaria (Metals Science) will cooperate with the SME Gas and Oil Consultancy (BB and Associates) in Poland in acquiring additional relevant data from CCE/NIS countries.
The academic partners in the technological universities of Miskolc (Hungary), Vienna (Austria) and Bradford (UK) will assist especially in defining the different damage processes (brittle fracture, corrosion, fatigue, stress corrosion cracking, corrosion fatigue) and assessing Non-Destructive Testing (NDT) methods applied to pipelines and the repair technologies used, world-wide. Analysis will be supported by laboratory testing (including actual pipeline sections by internal pressurization) and failure analysis by modern microstructural and microanalytical techniques.
In developing the Assessment of Reliability Module (ARM) for the KBS, reference will be made to existing CODE-s for flaw assessment and lifetime estimation methods used in different countries. Software will also be developed to allow data derived from case studies to be incorporated into the KBS.
In establishing its advanced KBS, the consortium will build on existing cooperation in developing pipeline management systems between Bay Zoltan Institute - Institute of Problems of Strength-Transneftediagnostika and Miskolc University - Hungarian Oil and Gas Company respectively. These industrialists will pilot test the consortiums' KBS and BB and Associates seek its exploitation by further pipeline operators.
Technical leadership will be provided by Bay Zoltan Institute and coordination by the University of Bradford.
The proposal conforms with Worksector 7. 3 specifically -
Maintainability and reliability: Development of support tools for improved product performance, reliability and maintainability. To advance the capability and applicability of mathematical modelling supporting design, including the integration of modelling techniques with defect and failure mode analysis needed for reliability and predictive maintenance.
