Feedwater Heaters and Rotor Replacement
Market: Nuclear
Location: South Carolina
Problem
Extremely tight quarters and equipment limitations slowed down the project.
Solution
Quick thinking and new devices helped complete the job.
Description
Barnhart was contracted to remove and replace rotors and feedwater heaters. The rotor was railed to site, offloaded with the 44A system, and transported easily to the crane bay.
However, when the old rotor was loaded to a nine-line trailer for transporting to storage, the crane failed at a height of nine feet off of the ground. With engineering approval, we were able to load crane mats (five high) on the trailer and safely rescue the rotor from the inoperable crane.
After that, we quickly finished the remainder of the job.
Moving the feedwater heater challenged us as well. The 4B sat under a floor and we slid it out using a light slide. Furthermore, we inverted both the 4A and 4B to clear surrounding obstructions.
We used the new basketing devices on their maiden voyage and found that they were easy to use, and that they served their purpose well.
Next, we directed them through the legs of the gantry crane, between the MSR's, down a low risk path on the Turbine Deck, and finally to the crane bay.
With the successful nuclear project, four employees gained their "nuclear" badges, making them invaluable help for future nuclear jobs. They will be particularly helpful to speed up our work in case we need faster reaction time.
