We performed inspection and maintenance services on the Red Dog Mine’s dock and loading cells. The project involved underwater video and photographic inspections of the sheet piles, along with underwater welding to install additional passive anodes. During the dock inspection inspection, the dive team discovered loose bolts attaching the diffuser assembly. Cell calibration and reference cells were included in the dive package, plus underwater welding and burning equipment, a support vessel, a flyaway dive system, underwater video and still photography equipment, a portable generator, and a digital thickness machine.
