Three typical scenarios from three sectors — with identical demands for documentation depth and reproducibility.
Ports & marine construction
Example scenario
ROV inspection
Example scenario Ports & Marine Construction — quay wall and dolphin inspection
Typical situation: A port operator wishes to document the condition of several dolphins and a quay wall section — for example as the basis for maintenance planning or a recurring structural inspection. Conventional diver operations are costly and often produce only verbal protocols without a comparable data basis.
Approach: ROV inspection with HD camera and lighting. Systematic traversal of structures along a defined route with video recording. Targeted stills at damage locations, biofouling zones and joints. Harbour operations typically continue.
Result: Structured findings report with image references, damage classification and recommended actions. Handover to the planning engineering office within a few working days depending on scope.
Deliverables: HD video · selected stills (e.g. 100–200 depending on scope) · damage classification table · findings report (PDF) · method protocol with route for follow-up inspection.
Scope: 3 mooring dolphins + approx. 120 m quay wall
Duration: approx. one day, depending on current and visibility
Diver logistics: can be reduced or partially replaced depending on the task

Industry & energy
Example scenario
ROV + Sonar (optional)
Example scenario Industry & Energy — basin or cooling water inspection
Typical situation: An industrial or energy operator wishes to inspect a cooling water, process water or storage basin without fully interrupting operations. Draining is often neither economically nor operationally feasible — for example with facilities that continuously supply cooling or process water.
Approach: ROV deployment, depending on visibility, geometry and safety requirements. Optional sonar support for areas with restricted visibility caused by suspended matter. Video coverage of floor, walls and inlet sections along a documented route.
Result: Documentation of visible deposits and condition features. Report with comparison photos as a possible monitoring baseline for future recurring inspections. Basis for internal maintenance planning and budgeting.
Deliverables: HD video · optional sonar dataset · selected stills · deposit map · monitoring baseline report · reproducibility memo for the follow-up inspection.
Scope: e.g. 500–1000 m² basin area
Duration: depending on geometry and visibility
Operational interruption: often avoidable or reducible, depending on safety clearance and facility

Authorities & municipalities
Example scenario
Structural inspection
Example scenario Authorities & Municipalities — bridge pier inspection
Typical situation: A public body, planning office or asset owner needs a traceable underwater condition survey of bridge piers or other hydraulic structures. Requirement: authority-ready documentation that can flow into an inspection file or structural database without rework.
Approach: ROV inspection of each pier on all four sides, from waterline to riverbed. Documentation of scour, biofouling, concrete condition and joints along a reproducible route.
Result: Photo documentation with position reference per pier, summary report in a format suitable for the inspection file. Used as a comparison baseline for future inspection cycles — the first data point of a time series.
Deliverables: HD video · position-referenced stills (e.g. 100–200 depending on scope) · findings report in a format suitable for inspection files · damage classification · method and reproducibility memo · handover-ready data structure for inspection file or structural database.
Scope: e.g. 4 bridge piers depending on the structure
Duration: depending on current, visibility and structure size
Diver logistics: can be reduced or partially replaced depending on the task
