Gazprom will suspend Nord Stream 1 flows completely for three days at some point between late August and mid-September, citing the need to conduct maintenance on a compressor unit at the Portovaya compressor station.
In a Telegram post on Friday afternoon, Gazprom said flows will suspended for three days to conduct maintenance on the “only working Trent 60 gas compressor unit”.
“For the maintenance period of the GPA Trent 60 DLE from 08/31/2022 to 09/02/2022, gas transportation through the Nord Stream gas pipeline will be suspended for three days,” Gazprom said.
The works will be carried out jointly with Siemens, Gazprom said.
“In accordance with the technical documentation of Siemens, every 1000 hours it is necessary to carry out maintenance of the unit, which includes: inspection of the casing for cracks, dents, deformations, burn marks, cleaning of the casing; inspection of oil supply systems, air, removal of combustion gases for leaks, broaching of connections and elimination of causes of leaks; Checking the operation of safety valves and adjusting the air flow control system,” Gazprom said in a statement.
The announcement sent European gas prices spiking, with TTF and NBP having hit five-month highs this week amid heightened winter supply concerns.
Gazprom says NS1 flows will resume “upon completion of work and the absence of technical malfunctions of the unit” at a rate of 33 MMcm/d – in line with current flows through the pipeline running from Russia to Germany.
The complete halt to NS1 flows will add further complications to Europe’s gas storage target – aimed at having storage sites 80% full by 1 November. Storage sites across Europe have been filling ahead of schedule, with inventories 75.89% full as of 17 August, according to GIE data. - ET
