For tank owners
Most owners are asked to approve a shutdown in order to discover whether a shutdown is needed. An in-service inspection answers the question first, while the tank stays full and available.

Anthony: Shot from the owner's side of the fence, not ours. Open on the site running normally — water moving, plant working, a gauge holding steady. A contractor's van arrives, a tripod goes up on the tank roof, and that is the entire disruption. Cut to the screen the owner is shown: the floor of their own tank, the sediment, the map of where it sits. Close back on the site, still running, and the crew driving away. The owner never sees a fence line, a drained tank or a permit.
The situation
Sediment accumulates slowly and invisibly. By the time it is costing you usable capacity, affecting pump performance or putting product quality in question, the only way to confirm it has traditionally been to take the asset out of service — which is the very thing you are trying to decide about.
An inspection carried out while the tank is in service turns that around. You get the evidence first, then decide what the work should be, and what it is worth.

Anthony: The evidence an owner receives. A frame from inside a tank showing real sediment on the floor, ideally paired with the sonar depth map of the same tank. This is what they are buying: knowing.
What an inspection gives you

Anthony: A single clear frame off the robot's own camera inside a tank — a column base, a wall joint or a fitting, lit by the machine. It should look like evidence, not marketing: the kind of frame an owner would forward to their engineer.
Recorded camera survey of the floor, walls, columns and internal fittings, with anomalies logged where they are found — whatever the tank holds.

Anthony: The sediment depth map of a real tank — the colour plot with the tank outline around it. Ideally the same tank as the frame in the card beside it, so the pair reads as one survey.
An acoustic profile of the sediment gives depth and distribution across the floor, so the volume is measured rather than estimated.

Anthony: The deliverable as an object. A printed survey report on a desk, open at the floor plan, with a laptop showing the same data behind it. Any client names blurred or removed.
Findings you can put in front of your own maintenance contractor, or use to compare offers on equal terms.
The tank stays full and in service throughout. Everything above is obtained from outside, with the asset working normally.
How it happens
Paragonix Tek builds the robotic systems and supports the companies that operate them. The cleaning and maintenance work is always carried out by a maintenance company — ours, or yours.
A light inspection to establish what is in the tank and what condition it is in — enough to specify the work, and yours to use however you choose.
Where a company operating our equipment is well placed for your site, we put you in touch. The work, the contract and the relationship are then theirs and yours.
If you already have a maintenance contractor, they can be trained and equipped to do this work themselves — or we support them on the first job.
How we help
We help you establish what is in the tank, what condition it is in, and what the work ought to be. The maintenance itself is delivered by a maintenance company — your own, or one operating our equipment — with our engineering support behind them.
That arrangement works in your favour. The findings are yours to take wherever you like, and the contractors who already serve you keep serving you.
Applications
Start with the tank
Tell us the tank type, roughly how big it is, the access opening and where it is. We will tell you whether an in-service inspection is the right answer — and if it is not, we will say so.
