Vibrations – but no access to the plant?
In the present case “dancing cooler racks” in a LDPE plant were the reason for the operator to call KÖTTER Consulting Engineers for a vibration analyze. However, The piping system of such a plant is set up in an EX-rated environment inside of a bunker, which is normally prohibited to enter during operation.
Therefore, vibration issues are often tackled with either simplified spot measurements at distinct locations or extremely complex and expensive measurement setups. Nevertheless, it is more or less impossible to get a full picture including operational deflection shapes as well as reliable and comprehensive assessments.
