FPL speeds reconstructionwith new CAD system

In the aftermath of Hurricane Andrew, which brought 1,240 mile-per-hour winds into southern Florida, 1.4 million Florida Power & Light Co. (FPL) customers were without electricity. Not only were the lines down, but many generating plants also suffered damage, including Turkey Point nuclear power plant. The hurricane wiped out a 100,000 gallon elevated water tower, a 500,000 gallon water storage tank, city water supply piping, three service water pumps, four raw water pumps and a fire water pump. The plant`s Production Engineering Group (PEG) had to quickly redesign the damaged equipment and put the plant back in normal operation. This task involved recreating almost 200 design drawings from outdated drawings, photographs or from scratch.

“Fortunately, we had recently replaced our PC system with an Ethernet client-server network running workstations and servers from Sun Microsystems Computer Corp. and AutoCAD Release 12 version C2 software from Autodesk Inc.,” said Jeffrey Keech, PEG senior mechanical designer. “In less than eight weeks, we had completed all of the drawings. It would have taken up to 40 percent longer on the previous computer system.” Networking enabled the group`s drafters and designers to electronically share drawings and data among themselves and with other groups at the plant. The most recent drawing version was always reflected on the server, eliminating storage and back-up problems.
