How it works
Robots used
- Cleaning ROV
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.
