(Maintenance Strategy Optimisation) programme (initial increase in maintenance costs, breakeven after 2 years followed by significant savings years 3 to 5 year [and steady annual increases in savings if it’s part of a continuous improvement programme]). This graph depicts the solution to a maintenance challenge one to two orders of magnitude greater than winery maintenance. Notwithstanding, is there any reason why a winery cannot achieve similar success? Note: the graph shows a high level of ‘Autonomous Maintenance’ (maintenance by the equipment operators). Beware, autonomous maintenance needs to be an addition to the normal maintenance team activities. Retrench part of your maintenance team and hand some of their maintenance to your cellar hands and bottling operators at your peril. The result of this action in the vast number of cases has been disaster.
Wine Industry Suppliers Association (WISA) maintenance webinars WISA plan to produce a series of 20 one-hour webinars on winery maintenance challenges. The webinars will be made available on the WISA Wine Portal. These will deal with challenges such as • Reducing (or eliminating) Vintage HIMF (High Infant Mortality Failures) • Purchasing the correct CMMS (Computerised Maintenance Management Software) and making maximum use of its capabilities • Implementing CON MON (Condition Monitoring) and Predictive Maintenance • Introducing streamlined RCM (Reliability Centered Maintenance) and MSO (Maintenance Strategy Optimisation), including templates for one-person fast implementation • Implementation of LEAN and TPM, including the correct implementation of autonomous maintenance 42 Grapegrower & Winemaker
These webinars are being produced by me with assistance from Matthew Moate, WISA’s CEO. They are planned to be launched in the near future. These webinars will be an expanded version (approximately double) of the two-day winery maintenance workshops I have been running from time to time.
Conclusion My assessments are: • High Infant Mortality Failures (HIMF) are probably 60 to 70% of all winery plant and equipment failures • It is highly probable HIMF dominate the first 3 to 4 weeks of vintage • It is likely 80% of all winery plant and equipment failures are random and 20% are age related predictable life failures. I am convinced detailed research into winery plant and equipment failures will prove these assessments are correct. WISA Wine Portal winery maintenance webinars are recommended as tools to: • Train winery teams in winery maintenance best practices • Contribute to improved winery availability, reliability and productivity and hence profitability (and indirectly contribute to wine quality).
