Underwater Tank Inspection Platforms

Bristola's patented equalization chamber entry system functions as an airlock-type portal, allowing the submersible robot to enter and exit tanks or covered lagoons through any existing manhole 24 inches in diameter or greater — without draining the tank or halting facility operations.

No. Bristola's platforms are designed as zero-human-entry systems, completely eliminating the need for confined space entry. This removes the associated OSHA permit requirements, reduces worker risk to zero, and significantly simplifies the regulatory compliance burden for facility operators.

Bristola's underwater tank inspection platforms are suitable for anaerobic digesters, covered lagoons, wastewater and water treatment plants, food and beverage processing facilities, pulp and paper mills, oil and gas refineries, steel mills, agricultural waste systems, and biogas production facilities.

Yes. The patented equalization chamber entry system can be installed as a retrofit on existing facilities as well as integrated into new builds. Any manhole 24 inches in diameter or greater is compatible, making it accessible for most operational liquid storage tanks and covered lagoons without major structural modification.

Based on Bristola's case study data, facilities can save approximately $80,000 per tank per year compared to traditional cleaning methods. The annualized cost using Bristola's system is approximately $170,000 versus $250,000 for conventional approaches, with no temporary storage or production stoppage costs factored in.

Bristola's Submersible Robotic Cleaning System includes sonar navigation, real-time performance monitoring, and comprehensive data evaluation and reporting. The full-service system cleans, evaluates, and stores data on facility condition and performance, and sediment mapping services using advanced sonar technology are also available.
