Dam / Reservoir Inspection, Repair & Maintenance (IRM)
Tens of thousands of dams are in operation across the United States, making their safety and reliability of national, state, and local importance. Regularly scheduled underwater inspections and maintenance can help ensure they remain operational and readily identify areas to be addressed. To complicate matters, much of a dam’s structure is underwater, requiring experienced diving personnel and specialized resources to perform the work.
Whether you need highly trained diving personnel, an eyeball Remotely Operated Vehicle (ROV), or the use of our sophisticated Atmospheric Diving System (ADS), Phoenix has the skills and tooling to perform these assessments accurately, and IRM works.
