The gas transfer station in the north.

The natural gas transfer station in Lubmin near Greifswald is the main interface between the Nord Stream offshore pipeline and the two connecting pipelines, OPAL (Ostsee-Pipeline-Anbindungs-Leitung – Baltic Sea Pipeline Link) and NEL (Nordeuropäische Erdgas-Leitung – North-European Gas Pipeline), which transport Russian natural gas on to European transport customers.

The station consists of two sections: the "offshore section" for the incoming Baltic Sea pipeline and an "onshore section" for OPAL and NEL, the two downstream gas pipelines. The onshore section is sub-divided into a "180 bar" and a "105 bar" plant area. The "180 bar" area has filters, pre-heaters and control valves. To prevent gas hydrates or ice from forming, the gas undergoes additional pre-heating after cleaning and prior to being fed into the downstream pipelines.

Mainly measuring and control systems have been set up in the "105 bar" section – separate measuring sections use ultrasonic meters and density measurement to determine the current gas throughput for OPAL and NEL, before the gas leaves the station via the transport pipeline.

The receiving terminal in Lubmin has been planned and approved so as to enable additional natural gas compressors to be constructed, if required, with a possible view to increasing the required input pressure for the OPAL and NEL gas pipelines.
