FIELD: machine engineering.
SUBSTANCE: group of inventions relates to transport gas trunkline (TG) and can be used in gas extraction cases with pipe sections before the repair work and the use of selected gas as fuel in the gas pumping units (GPU) with the gas turbine drives. The invention consists in the laying of an additional pipeline section diameter of at least 150 mm from security cranes COP multiline system MG to the pipeline's own needs KC, connecting it between the existing bypass shutoff valves security valves to the existing pipeline own use KC for the selection of natural gas from the disconnected portion of the TG to the COP in a multi-line system and a natural gas treatment plants fuel , starting and pulse gas.
EFFECT: increased efficiency emptying the main transport stations of natural gas, reduction of losses during repair work on the main transport, improve environmental safety.
