VideoRay announced today that a new video is available free to professionals who perform underwater inspections of dams, bridges, portable water tanks, and other submerged structures. Historically, divers have performed these inspections. VideoRay ROV offers an alternate method that avoids the hazard, expense, and difficulties in scheduling routine and unplanned inspections.
Among other projects, the video shows a gate slot seven feet deep and just 20 inches wide, where a lift cable had broken. The compact, 8-pound VideoRay was quickly deployed into the narrow opening and followed the cable about 65 feet down to its connection. There was no need for a manned inspection and, using the video captured with the VideoRay, the diver hired to do the repairs had a clear understanding of the situation he would encounter on the job. The VideoRay was also used for safety to monitor the diver’s work.
The video also shows a situation where an obstruction was preventing a gate from closing completely. The VideoRay was able to follow the gate rails 170 feet down to the seat, where sand buildup was discovered. The operators then knew what corrective action would be required before they divers were sent into the water. Also featured on the video is a dam, where debris previously jammed behind the gate lift cable had caused uneven lifting of the gate and possible damage to the connection hardware. Despite visibility of less than 18 inches, the operators steered the VideoRay Pro in a vertical descent along the cable, inspecting it as they went, until they reached the connection.
VideoRay is non-contaminating, making it the tool of choice for water tank inspections. Because of its small size, light weight, and 250-foot neutrally buoyant tether, VideoRay is easily deployed into enclosed structures. Water tank inspections can be performed from the ground. When contractors are standing by to begin work, VideoRay can be sent in the water for last minute inspections and prevent costly delays.
The VideoRay ROV is contained in two watertight transport cases, one with wheels. One case contains the control panel and power supply and the other holds the ROV and tether, totaling a weight of just 60 pounds. The system can be powered from standard 115 or 240 volts AC or by a battery-powered inverter. System setup takes moments, with a simple connection of cables for power, video display, and tether. After a quick test of all systems, the ROV is lowered by its tether into the water.
