Feedwater Heater Remove and Replace

Barnhart was hired to remove and replace two feedwater heaters at a nuclear plant in Michigan. The team engineered a travel path solution using powered saddle rollers and over under beams that allowed for multiple turns on the removal and installation paths.

Barnhart used customized jack stands and pull-up jacks and beams for a more efficient jacking system.

Barnhart also used its new catenary saddles, a lower profile option to conventional saddles.

The feedwater heaters were loaded onto a Goldhofer PSTE for both removal and installation. A major challenge was the limited wall opening size that made for tight clearances. Barnhart and the customer worked together on a plan and executed the scope of the project well.
