ERLANGEN, Germany – WINGAS has purchased a 36-MW SGT-750 industrial gas turbine from Siemens for use in the Nord Stream gas pipeline project in northern Europe.

The turbine will be installed in the landfall station of the Nord Stream pipeline in Lubmin near Greifwald, Germany.

The SGT-750 turbine will be deployed in a cogeneration plant at the landfall station, where generated electric power will be fed into the grid. Heat from the SGT-750 will reheat the pipeline gas which loses pressure during its journey from Siberia under the cold Baltic Sea, restoring it to the temperature required for further distribution, and compensating for the Joule-Thomson effect which causes cooling of the gas during a pressure drop.

Siemens will supply, install and commission the turbine, generator and auxiliaries, and the electrical infrastructure for the grid connection.

The company claims the SGT-750’s electrical efficiency of 38.7%, which corresponds to a shaft efficiency of 40%, provides the highest uptime in its class.
