Analysis of the functional dependability of underground gas storage compressor stations in cases when actual performance indicators deviate from the design values

Aim. The paper examined the matter of assessment functional dependability compressor stations (CS) underground gas storage (UGS) facilities. A definition CS and guidelines for its were proposed. Methods. Design calculation stations, scenario analysis. Results. presents: a) a definition, indicators assessment; b) an example application UGS CS; c) comparative analysis in number various versions: use single-unit two-unit centrifugal compressors as part turbine pumping units two-stage compression with intercooling. Conclusion. shows requirement to analyse versions purpose identifying most rational option that ensures unconditional performance key function under uncertain initial design data.
