Gazprom reported that during maintenance work on the Trent 60 unit at the Portovaya compressor station, an oil leak was detected. The company also posted a photo of the malfunction.
“An oil leak with an admixture of a sealing compound was detected at the connectors of the terminal connections of the cable lines of the low and intermediate pressure rotor speed sensors,” the report says.
Oil was also found on the cable detachable connection of the BPE2 connecting plate, which is part of the engine.
“Oil was also found in the area of the cable line in the external terminal box of the GPA automatic control system outside the noise and heat insulating casing,” the company said.
The act of detecting an oil leak was signed by representatives of Siemens.
A letter regarding the identified faults and the need to correct them was sent to the President and CEO of Siemens Energy AG, Christian Bruch.
As Rostekhnadzor emphasized in its warning, the detected malfunctions do not allow for safe trouble-free operation of the engine, and in accordance with Siemens information, the complete elimination of oil leaks on these engines is possible only in the conditions of a specialized repair company.
Until the comments on the operation of the equipment are eliminated, the transport of gas to the Nord Stream gas pipeline has been completely stopped, the company reminded.
On August 31, the only working gas compressor unit Trent 60 at the Portovaya compressor station was stopped for three days for maintenance.
Moscow emphasized that EU sanctions brought the situation with the suspension of the gas pipeline.
