Maintenance on Bulkhead and Siphons at the Norfork Dam and Power Plant

MCDI inspected and mapped the spillway face of the Norfork Dam for irregularities, completed the underwater installation of 42" diameter siphon tubes, core drilled the dam face and installed Williams rock bolts, and installed a valve stem replacement on the fish hatchery portion of the project.

This was a deep water diving project with diving depths of up to 150'. MCDI utilized SurDO2 diving operations and company-owned decompression chambers on our barges for this project.
