Construction of the looping system (total length - nearly 700 kilometers) is in full swing. To date, 626 kilometers (more than 90 per cent) have been welded up, 515 kilometers (around 75 per cent) of those have been trenched and buried. Gas compressor capacities are being expanded at the Portovaya, Gryazovetskaya, Babayevskaya, Pikalevskaya, Volkhovskaya, Elizavetinskaya, Sheksninskaya compressor stations (CS).
