Services
Tank Inspection
Advanced Diving Service performs comprehensive inspections of potable and non-potable water tanks using ROVs and divers. We assess corrosion, structural integrity, and cathodic protection systems while tanks remain full. Digital imaging and detailed reports highlight issues like sediment buildup or coating failures, ensuring compliance with AWWA standards and state regulations.
Tank Cleaning
Our patented Hydro-Vac system cleans tanks without draining, eliminating sediment that harbors bacteria and depletes chlorine. This method preserves tank coatings, reduces downtime, and maintains water quality. Clients receive documented results showing improved tank conditions and reduced health risks from contaminants.
ROV Services
Remotely Operated Vehicles (ROVs) inspect tanks, pipelines, and submerged structures with high-resolution cameras and sampling tools. This technology enables safe, cost-effective assessments of hard-to-reach areas, providing real-time video and data to identify corrosion, leaks, or structural damage without human divers.
Hazmat Diving
Certified hazmat divers handle high-risk underwater tasks in contaminated environments, including nuclear plants and wastewater facilities. Equipped with self-contained gear, we perform sludge removal, repairs, and inspections 24/7, prioritizing safety and regulatory compliance for urgent industrial needs.
Underwater Construction
From hydroelectric dams to pipelines, our divers execute underwater welding, cutting, and structural repairs. Services include epoxy injection, steel reinforcement, and installation of water screens. Projects are documented with narrated DVDs to ensure transparency and adherence to engineering specifications.
