Dive Inspections at Falls River Hydro Dam
June 21, 2017
When you’re called to a remote location for underwater inspections on a hydro dam, you need to know who to bring, and what to pack. Mobilization was a key factor for Valard Dive Services in reaching Falls River Hydro Dam, located at the confluence of the Ecstall River and Big Falls Creek. In early May, the team packed a landing craft with specialized equipment and traveled to the facility from Port Edward.
The goal of this project was to inspect components of the dam infrastructure.
Regular inspection and maintenance of any hydro facility is crucial, by which divers act as an integral component.
The, highly trained and experienced, dive crew had a big job ahead. The team members included:
Diver 1: performs underwater tasks.
Diver 2 (standby): At the ready, in case Diver 1 needs assistance.
Tender: Variety of duties including running the compressors, helping to dress the divers and manage the air hose.
Dive Supervisor: Directs the operation, communicates with the diver using real-time video and audio technology, as well as manages the divers' air supply and backup systems.
For VDS, safety in completing this project was the number one priority. Before any diving were to occur, VDS and BC Hydro held a meeting to ensure all operations would be conducted in a safe manner. Both companies then coordinated to lockout various components of the dam, which could pose as a hazard to the diver. The diver spent approximately an hour and a half in the water, completing all tasks to satisfaction. For the VDS crew, it was all in a day’s work.
