We work on the Siemens gas turbines built in Lincoln UK, Siemens Lincoln, formerly Ruston, European Gas Turbines and EGT Alstom. When Siemens purchased the Alstom Lincoln and rebranded to Siemens Lincoln, they also changed the old turbine names, formerly the Typhoon, now SGT100, Tornado, now SGT200, Tempest, now SGT300 and Cyclone, now SGT400.
