Abstract
In order to maintain the safe operation of the pipeline any deteriorations should be eliminated in time.The system approach to the pipeline operation provides its safety. This approach presumes that a complete package of interconnected objectives must be fulfilled:- Overall inspection survey of pipeline network based on the usage of "intelligent" inspection tools featuring high performance and high resolution;
- Automated processing of inspection survey results;
- Strength calculations performed on the basis of inspection data, identification of all severe defects and calculation of allowable operation pressure for them;
- Prioritization of repair for severe defects, based on the strength calculation results;
- Regular inspection survey of each section of pipeline system with optimum inspection frequency;
- Use of effective technique for pipeline prompt repair based on the results of inspection survey (predominantly without oil pumping stoppage).
Such approach is implemented at AK "TRANSNEFT" with SKUTOR system - System for Monitoring and Control of Maintenance and Repair, which is currently developed.
The availability of the inspection data may allow us in the future to override the expensive tests by the non-destructive test methods, to selectively repair the pipelines, which will make it possible to rationally allocate resources and funds to ensure safe, controlled conditions of operation with the minimal expenses for their implementation.
