Understanding the technique
Uses remotely operated underwater platforms for visual inspection and suitable instrumented examination tasks. Operations are planned to obtain traceable evidence from the required locations.
Where it adds value
Subsea structures and marine assets where remote inspection is appropriate.
The purpose is to provide evidence that supports a defined asset decision: prioritizing maintenance, investigating degradation, assessing serviceability or documenting equipment condition. The examination is planned around the asset's operating context and the information needed by the owner.
Inspection outputs
Video, location references, inspection observations and instrument readings within the agreed scope.
Planning considerations
Vehicle configuration, currents, visibility and tether management influence the operational plan.
From scope to decision
Provide equipment identification, drawings, material details, operating conditions and previous inspection records where available.
Confirm the inspection objective, accessible locations, coverage, acceptance basis, site arrangements and reporting requirements.
Review recorded findings against the agreed scope, identify any coverage limitations and define the need for further inspection or engineering assessment.
Project questions
What information helps define a quotation?
Share the asset type, location, quantity, inspection objective and desired schedule. Drawings, previous reports and access information help the team prepare a realistic scope.
Can this technique be combined with other services?
Yes. Complementary examination or engineering assessment may be needed to characterize relevant findings. The combination depends on damage mechanisms, material, geometry and the decision required.
