Dzhus A. The development of scientific bases of equipment performance assurance in compressed natural gas transportation

The dissertation is devoted to solving the important scientific and applied problem of equipment performance assurance in the implementation of compressed natural gas transportation processes across offshore zones. The paper established the influence patterns of charts and speeds for feeding process of the high-pressure reservoirs, constructed in the form of movable pipelines, onto their strain-stress state. The conditions of ring cracks formation in composite reinforcement of combined type reservoirs, peculiarities of reinforcement coupling with metallic liner in operation, were investigated, the impact of cracks presence for metallic liners strain and stress state formation, considering the possibility of corrosion damage, were assessed. The theoretical and methodological principles of processing offshore transport facilities, stocking with equipment for gas treatment and loading, got the further development, the new approach for unloading operations optimization of offshore transport facilities into existing gas transport infrastructure was proposed. The method and operability tools for compressed gas transportation, taking into consideration the existing technical state and loading due to the processes implementation peculiarities were developed. The new criterion of excellence for comparative assessment of various type and operating pressure reservoirs, determined by the ratio of the mass of the reservoir to the volume of gas to be transported in it, reduced to normal conditions, was proposed.
