We arrive with our own system and operators, survey the site and hand over a report. One-off, or on a subscription with regular monitoring.
Inspection intervals are set by documents, not by the owner's preference. Hydraulic structures - every 5 years, and since September 2025 this is mandatory for facilities over 25 years old. Underwater gas pipeline crossings under navigable waters - at least every 3 years. Underwater parts of bridge piers - at least every 10 years. Vessels arriving from foreign ports are inspected on call.
Qualified divers are in short supply, and an underwater hull inspection can cost hundreds of thousands of roubles or more. In ice conditions diver inspection is sometimes technically impossible - there the vehicle is the only option.
To be clear: for a formal report on port structures the rules require divers from accredited organisations. The vehicle takes the volume off the diver: pre-survey and area mapping, documentation and less time underwater - and therefore lower cost.
We don't only build vehicles. Our own crew goes out to sites and runs surveys with our own systems - and we also service the equipment of those who bought a PROMETEY.
We arrive with our own system and operators, survey the underwater structure and hand over a finished defect report. No need to buy a vehicle, train people or keep equipment - our crew does it all.
Bought a PROMETEY - we service it in Russia: warranty, spare parts, repairs, software updates and operator training. The vehicle is supported where it was built, with no reliance on imports.
Scheduled every five years, unscheduled after a storm, flood or vessel impact, defect assessment before repairs. We arrive, survey and hand over the report.
Travel, survey, data processing, a report with findings mapped to the structure.
Survey from one day, report within a working week after the visit.
Photo and video, a list of defects, a 3D model of the structure if needed.
One structure, rare surveys, a one-off reason.
Regular scheduled visits: you see the structure's condition over time, and the survey budget is known in advance instead of jumping from case to case.
Visits on an agreed plan. Fish-protection devices twice a year.
The same survey points every time: you see how a defect develops between surveys.
A fixed annual price, with no unplanned service procurement.
Several structures, or surveys required regularly by regulation.
You describe the site and the task
We send a quote and a work programme
Five-minute deployment, work on site
Processing and handover of materials
If you survey one site once every five years, there's no point buying a vehicle - and we'll say so. If surveys are regular, we'll work out the volume at which buying the system pays off.
