Penstock Inspection – Remote Operated Vehicle Inspection ( ROV )
Inspection of the internal surface of the penstock head gate slots needed to be performed. Utilization of a Ballard ROV was done to perform the inspection. Documentation of all in water work was done via digital video recording systems and stored to a hard drive for viewing by the client both in real time, and later as needed. The Ballard ROV pilot took still photos, recorded underwater SD and HD video and utilized sonar to both inspect and gauge the approximate wear or out of round conditions of the penstocks.
ROV is often a less expensive and safer option for hydroelectric installation inspections as well as other industry applications. It is for that reason that Ballard maintains a variety of types of ROV’s so the right vehicle is used for each application.
