Predicting, Understanding and Avoiding the Ekofisk Rotor Instability Forty Years Later
MetadataShow full item record
This famous machine is re-examined to assess how well (or not) current design and analytical methods have evolved to avoid shaft whip instability. In addition to reviewing the compressors history and design evolution, the rotordynamic performance of a newly configured machine, based on todays technology, is compared against the original design.
