Centrifugal Compressor Rotordynamics in Wet Gas Conditions

Giuseppe Vannini is a Principal Engineer in the Advanced Technology Organization of GE Oil&Gas, which he joined in early 2001. He has been involved in advanced rotordynamics studies on high performance centrifugal compressors developing both analytical and experimental research activities. After leading the first subsea compressor prototype design up to the final FAT he came back to full-time rotordynamic activity and he’s active especially in the field of annular seals modeling and testing, advanced gas and oil bearings validation. He holds a PhD in Mechanical Engineering at Pisa University and he’s member of API684 Task Force.
