Wells Dam - Rehabilitation of a turbine wheel
CHALLENGE
Our client entrusted us with the mandate to rebuild a Kaplan-type turbine wheel, which is almost 8 meters (26 feet) in diameter. The assembly of this complex part consisted of more than 5,000 components. The main challenge was the complexity of managing the multiple stages of the cycle: disassembly, cleaning, inspection, repair and / or replacement with new parts, welding, machining and assembly. A refurbishing project involves a degree of uncertainty about component wear and has a significant impact on planning.
SOLUTION
The great skills of our technical team allowed us to propose solutions to minimize costs and to stay on schedule despite the unexpected. Our numerous equipment allows us to have greater production flexibility in a context of repairing many parts of all sizes. In addition, the variety of processes that we offer internally (welding, NDT inspection, machining, painting, assembly and logistics) considerably reduces cycle time.
RESULTS
Thanks to the coordination and cooperation between the teams of our various departments, the refurbishing went well and we delivered high quality parts, on time, to our client.
