AVT Reliability is frequently asked to investigate problems caused by structural resonance. This is the name given to the dynamic behaviour of a structural item of plant or machinery when excited near to one of its natural frequencies.

Typically, the main reason behind lubrication-related challenges are “lack of ownership”. Often the responsibilities are either spread out to a number of personnel who have higher priorities. When in fact lubrication is key to optimum reliability and ultimately return on investment.

Food & Beverage managers understand that Food Grade Lubricants and Machine Reliability are important. Here, AVT’s head of asset management, Frederic Thomas, presents opportunities for Food & Beverage companies to improve food safety and machine reliability and availability based on analysis of data from over 100 benchmark audits.

Balancing cost reduction and efficiency improvement targets is a common source of frustration for maintenance and engineering managers. For facilities that operate continuously with no window for unplanned shutdowns, poor reliability and availability of machinery is far more serious.

Between 10 and 15 per cent of pipework failures are caused by vibration-induced fatigue in onshore plants. Vibration-induced fatigue clearly represents a serious risk category, but how much vibration is significant, and how can we help reduce the risk?

One of the most important aspects of any overall maintenance and reliability programme is the effective lubrication of rotating and moving parts. ‘Fit and forget’ auto lubricators are often seen as a solution to this problem, however, truly ‘forgetting’ an autolube device can result in under and over-greasing.

Lubricants are the life-blood of any industrial plant, maximising the operational lifespan of production equipment and machinery and minimising the risk of downtime. John Chappell, managing director of AVT, looks at how production efficiency need not be compromised by the requirement to use food-grade lubricants - and how an effective lubrication management programme can assist in the general maintenance of a healthy plant.

Vibration induced fatigue of process piping systems is an important and fundamental failure mechanism. Although overall statistics are not available for onshore facilities, available data for individual plants indicates that in Western Europe, between 10% and 15% of pipe work failures are caused by vibration induced fatigue.

Modern acoustic emission technology is a very versatile, non-invasive way to gather information about a material or structure and was originally developed as a means of non-destructive testing and quality control.

Given the critical nature of lubricants and the frequency with which mechanical failure is related to the lubricating system, effective lubrication management is probably the most important single function within any planned asset maintenance programme.
