Subsea pipeline & cable inspection

ROVs and AUVs surveying subsea pipelines, cables and wind farm foundations.

People ask for this as: “subsea survey AUV”, “pipeline ROV survey”

How it works

Robots used

  • Work Class ROV
  • AUV

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 it costs

Published ranges, each with a receipt. Not quotes: your price depends on scope, location and date. older price = 18+ months.

What to specify and ask

Put these in your request and you'll get a real price instead of "it depends":

  1. Pipeline length, diameter and burial status
  2. ROV class needed and support vessel provision
  3. Location (port, offshore, inland water)
  4. Water depth
  5. Asset type (hull, pipeline, dam, cage)
  6. Visibility and currents
  7. Deliverables (video, sonar, NDT)
  8. Class society requirements
  9. 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.
