Compressor frame and baseplate repaired in parallel to save time

November 17, 2021

Burckhardt Compression supplied spare parts for a compressor from an Italian manufacturer to a refinery in Italy. While being on site with the field service crew installing the spare parts, the Burckhardt experts realized that the compressor showed some anomalies like extensive vibration. Burckhardt Compression Italy reacted quickly and proposed a full procedure to repair the compressor frame and baseplate in order to bring it back to stable operation. The customer agreed to the suggested repairs under the condition that the compressor is fully functioning for a scheduled shutdown only weeks from the order date. And holiday season was just around the corner.

“Following the technical intervention, the compressor vibration was eliminated compared to the past; and now, about a year after the intervention, we almost forgot about the compressor – it runs safely and reliably. Burckhardt’s readiness to act quickly and flexibly was a real added value that allowed us to look into the future with more confidence. We are very satisfied.”
