The first polyester fiberglass structure cooling towers were placed in operation on the AEP system during the period of 2008 to 2010. One of these towers is a counter-flow design while the other four towers are cross-flow designs. Surface blisters were found on 15% to 20% of the columns in two towers after 18 months of service. A majority of the fiberglass bearing pads have failed in 3 towers which caused the bottom of many of the pipe columns to vertically split and fail. Information will be presented on the above issues, field repairs and lessons learned.
