Feature ArticleMicro-ROV Provides Cost-Effective Way To Inspect Infrastructure
By Amanda Coulas
CAS Asset Management is a company that works on projects ranging from general infrastructure implementation to water irrigation plant, construction and agriculture project management. Aiding organizations to properly manage large-scale assignments without straining their resources or budgets is part of CASís expertise. Bill Riley, president of CAS Asset Management, and his team have years of real-world experience in construction and maintenance, as well as 20 years designing and implementing asset management solutions in the Florida area. When a project arose to inspect thousands of miles of stormwater pipes for a private irrigation company, Riley began looking for compact and affordable solutions to best inspect the integrity of the entire irrigation system.
This particular irrigation system services 6,000 homes, two golf courses and 1 million acres of commercial space in Florida. Water irrigation systems such as these often face challenges when it comes to fully inspecting their systems, primarily because the waterways are submerged and run for miles throughout communities. Often, completing a full inspection is too difficult, so only certain access points are checked from above. This practice leaves the pipes susceptible to damage that could be avoided with proper and thorough inspection and maintenance. Stormwater systems are crucial for flood prevention, and it is essential to ensure they are in working order for the safety of the community.
Another common issue is that these pipes often accumulate sediment. Due to the instability of the sediment it is impossible for a diver or a crawling vehicle to inspect the pipes without stirring up the resting silt, diminishing visibility. When there is a suspected problem, having the ability to see where the damage is can be critical to determining the necessary corrective steps to take. In order to avoid the sediment mixing with the water, draining the pipes is required to view their integrity. The disadvantages to this option are many: not only does it require shutting down this large irrigation plant, but it also comes at great expense, and with the risk of there simply being nothing wrong.
With two Deep Trekker (Waterloo, Canada) DTG2 micro-ROVs, depth rated to 250 feet, CAS Asset Management gained the ability to inspect the pipes in an affordable way. The company won the contract to inspect the irrigation system because Riley did the research to find a vehicle that could constantly inspect the system and enable the ability to produce in-depth analysis and plan operations accordingly. With the ROV, they were able to inspect every inch of the pipes without passing on a large equipment expense to the customer. Armed specifically with their Deep Trekker DTG2 ROVs, Bill Riley and his team could easily traverse and inspect the submerged pipes, with the ROV carefully floating above the sediment without disturbing it. The pipes range in size from 15 to 60 inches, making the compact and spherical shape of the DTG2 ROV perfect for the job. Inspecting the pipes is a constant job for the ROV operators—upon complete inspection of the waterways comes time to start inspecting from the beginning again.
Deployment of Deep Trekker DTG2 ROV
Daily, the team heads out on their all-terrain vehicle along with two Deep Trekker DTG2 ROVs in the back, ready to inspect a section of the irrigation system. This large-scale ongoing project requires inspection throughout the community. The team does not always have access to power or the ability to bring along a generator to power their equipment. This makes the unique design of Deep Trekker ROVs ideal for their projects. With batteries on board the ROV, operators can still complete their tasks in the most remote locations. Operation time on one three-hour battery charge is typically between six to eight hours. Employing two Deep Trekker ROVs ensures there is never down time on the job.
