FIELD: machine building.
SUBSTANCE: proposed system comprises pipeline section with permanently increasing diameter for gas expansion directly in gas line. Compressor stations are arranged at gas pipeline head facilities. Gas pipeline ID in every nest section increases relative to previous ID as 
length of every said section being defined by equation li+1=1,27li at equal roughness of inner surface of adjacent section, where di, li, are section diameter and length, respectively. Aforesaid sections are jointed together with adapter diffuser section with taper angle of 20-24 degrees. Pipeline sea sections are made from polypropylene and arranged in waster by means of anchor device furnished with disconnector. Near-shore and moorland pipelines are arranged on pontoons provided with stabilisers.
EFFECT: expanded performances.
