The Choice Is About Exposure And Coverage
ROV is not a cheaper diver. It is a different instrument: better at covering distance and depth consistently, weaker at tactile assessment and any physical intervention.
Decision Criteria
- Depth and current beyond efficient diver working conditions
- Long routes requiring consistent coverage
- Confined or hazardous access
- Need for a repeatable visual baseline
Combined Scopes
The most common arrangement is ROV first, diver second: remote survey identifies where intervention is required and diver time is then spent only where it adds value.
