Penstock & hydropower inspection

Crawlers, drones and ROVs inspecting penstocks and turbines.

People ask for this as: “penstock inspection robot”

How it works

Robots used

  • Crawler
  • ROV

Ways to buy it

  • Service — you pay for the outcome (one inspection, one show, X acres).
  • Raas — a subscription covering robot, software and support.
  • 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

  • Per-asset pricing (per turbine, per MW) is common.
  • Combine thermal and RGB in one flight to save mobilization costs.
