Bearing Design, Repairs & Upgrades

Optimized Bearings and Dampers Provide Long-term Solution to Vibrations

Over a 13-year span, a major South American oil company’s maintenance department fought recurring high vibrations in three gas reinjection compressor trains. To reduce the likelihood of machine trips, technicians field balanced each compressor once or twice a year and replaced the worn tilt pad journal bearings and O-ring dampers yearly.

The downtime from implementing these preventative measures and from trips in the compressor trains resulted in 1% capacity loss each year and additional flaring of the gas.

A thorough analysis of the compressors and an inspection of damaged components pointed to a two-part solution: Flexure Pivot® tilt pad journal bearings and ISFD® technology, an integral squeeze film damper.
