Marine & Underwater
Bathymetric & hydrographic survey
Uncrewed boats mapping depths of lakes, rivers, ports and reservoirs.
People ask for this as: “bathymetry survey”, “hydrographic survey drone boat”, “USV survey”
How it works
Robots used
- USV
- Sonar Boat
Ways to buy it
- Service — you pay for the outcome (one inspection, one show, X acres).
- Rental — the machine for days or weeks.
- Purchase Buy the robot (plus software and service plans, usually).
Bot or Not?
A robot makes sense when…
- The job is high, dangerous, or hard to reach
- It is huge or repetitive (acres, nights, square metres)
- You need data you will compare over time
- You need eyes on it right now
Hire a human when…
- It is small, low and one-off
- It needs hands, judgement or a repair
- Weather, permits or timing make robots awkward
- Nobody has defined the job yet
Here's the catch for this job
- Robotic ROV work can replace diver teams for many inspections — ask for both quotes.
- Hull cleaning with debris capture is required in more ports every year.

What to specify and ask
Put these in your request and you'll get a real price instead of "it depends":
- Location (port, offshore, inland water)
- Water depth
- Asset type (hull, pipeline, dam, cage)
- Visibility and currents
- Deliverables (video, sonar, NDT)
- Class society requirements
- Vessel availability
Rules and regulation
Underwater work may need class society approval (DNV, ABS, Lloyd's), port authority permission and environmental permits (e.g., hull cleaning capture rules).
General information, not legal advice. Rules change; ask the operator which permits they hold and verify them.
