Right place, right time

LNG Maintenance-FIVES

Stéphane Desbuisson, Fives Cryo, France, and Nicolas Teyssot, Fives Cryomec, Switzerland, explain why it is vital to predict maintenance precisely to optimize equipment efficiency and extend its lifecycle.

Equipment ages daily, regardless of how often or how intensely it is used. Without proper understanding of its behaviour, maintenance can become a headache for users who are not adequately prepared.

Preventive maintenance is critical for process, cost, and equipment reliability. However, one of the main questions raised is how to verify that the right maintenance is being performed at the appropriate time. This prediction may be difficult if the customer has not put in place proper monitoring for his installation and equipment. This monitoring can be achieved with a large amount of data for an operational performance follow-up, or specifically for the prediction of the maintenance time.
