Fossil Energy – Nord Stream
Gas transmission via the Nord Stream gas pipeline has been fully shut down, Gazprom revealed in a statement posted on its Twitter page late on September 2.
“During scheduled maintenance works at the Trent 60 gas compressor unit (GCU No. 24) of the Portovaya CS, which were carried out jointly with Siemens, it was discovered that there is a leakage of oil with a sealing compound in it that has reached the terminal connections in the cable lines serving the low pressure and intermediate pressure rotor speed sensors,” Gazprom noted in the statement.
The presence of oil was detected on the detachable cable connection of the BPE2 mounting plate, which forms part of the engine, and near the cable line located in the outer terminal cabinet of the GCU’s automated control system, according to Gazprom’s statement. A report on the detection of the oil leakage was drawn up, which was also signed by Siemens representatives, Gazprom added.
“Rostekhnadzor of Russia issued a warning that the detected faults and failures make it impossible to ensure the safe and trouble free operation of the gas turbine engine,” Gazprom said in the statement.
“Therefore, it is required to take appropriate measures and suspend the operation of the Trent 60 gas compressor unit in view of the identified gross violations,” Gazprom added.
“Gas transmission via the Nord Stream gas pipeline has been fully shut down until the operational defects in the equipment are eliminated,” Gazprom continued.
