8Bacardi Site Data

� Bacardi produces 75,000 cases per day

� Working 2 x 10 hour shifts = 3,750 cases/hr

� 9 Bottling Lines

� Largest size bottles run at 400/min

� Miniatures run at 1000/min

� When an unexpected stoppage occurs it can take over one hour to restore production to normal line speeds

� Bacardi stated maintenance costs $350k p.a. for replacement parts damaged by unplanned stoppages

8Bacardi Assumptions

� If lines are down for 40 minutes then 2500 cases are lost in normal 20 hour production day

� If a value of U$10 per CASE were assumed, this would equate to U$25,000 per event

� No cost estimates have ever been offered or confirmed by Bacardi

� The actual figure may be higher, say 40k-50k per event

� No details are available for scrap costs, lost taxes, rework, overtime to recover lost production etc

8Assumed Bacardi Savings

� Historically 20 unplanned stoppages p.a. - $500k cost

� Bacardi volunteered - replacement costs cut by $250k p.a.

� Jan-Dec 05 490 events occurred below 87% (IEEE Level)

� Omniverter corrected 475 of these

� If only 10% of events would have stopped production

this would be 47 events @ $25k each = $1,175k

� Total Assumed Savings = $1.425 million

� The Assumed payback period is less than 1 year

� Unless restored within 30 mins, pulldown of extruder

8The Solution

� Trailed 300kVA on one of 6 extruder lines

� Operations staff demanded unit for “their” line

� 1000KVA Installed Dec 1998 (10 years of reliable service!)

� Amcor MD “before the AVC, the slightest flicker of the lights and we had trouble, but now we never worry”

� May 2005, Amcor installed another 1000kVA unit at their expanded plant. This was 7 years after buying the first unit.
