RedZone Leverages Spectrum 90

When you dare to go where nobody else wants to, the right attitude and equipment is essential for success.

When RedZone Robotics Inc. was founded in 1987, it had both of those attributes and that has enabled the company to be one of the leading inspectors of hazardous materials and water and sewer mains in the United States.

"RedZone has inspected over one million feet of large diameter pipe in over 75 cities and communities across the U.S.," said Sam Cancilla, general manager. "Our clients include major engineering firms like HDR, Hazen and Sawyer, CDM and major cities including Houston, Las Vegas, Pittsburgh, Los Angeles and Seattle."

And wherever RedZone goes, so too does Inuktun Services Ltd. products like Inuktun's specialized Spectrum 90 camera, which RedZone uses alongside other sensors like sonar, laser and gas on its responder platform and floating systems.

"Inuktun's cameras are rugged enough to handle challenging environments and situations in which the responder is designed to operate while their digital operation complements our advanced technologies and data integration," said Cancilla.

To get the job done, RedZone employs more than 10 of Inuktun's Spectrum 90 cameras, an amphibious camera that features tilt and zoom, and can be used in a toxic environment as well as confined or submerged areas. The camera can be used for dam and lock inspection, reactor vessel inspection, foreign object search and retrieval, robotic and remote tooling and can also perform corrosion evaluations.

Depth rated to 30 metres (100 feet), benefits of the Spectrum 90 include a compact size for tight spaces, a lightweight construction, precise operation, the ability to operate in air and underwater and a built-in inclinometer. On a recent complicated project RedZone took on, those features proved key in its success.

"We had an in-service inspection of a mile long pipe," said Cancilla."It started off partially submerged and then went to fully submerged conditions requiring multiple sensors and the Spectrum 90 was used in both conditions with depths nearing 100 vertical feet in some cases. Having tracked out almost a mile through fully submerged conditions with varying levels of debris, fast velocity and high turbulence, the Spectrum 90 came out of submersion with a clear picture and lights shining through to the terminating MH in this difficult pipe to access."

RedZone provides its customers with leading-edge inspection services for large diameter pipes and other wastewater infrastructures. It provides customized reports that enable clients to determine where to clean, dig and re-line pipes.
