Search & Recovery Underwater
Lost or submerged objects can be safety-critical, operationally relevant or environmentally sensitive. Structured localisation and, where required, recovery calls for appropriate technology, a tailored methodology and traceable documentation.
Diverless localisation and recovery of underwater objects
Lost or submerged objects can be safety-critical, operationally relevant or environmentally sensitive. Structured localisation and, where required, recovery calls for appropriate technology, a tailored methodology and traceable documentation.
SCANSUSTAIN provides diverless underwater search and recovery operations enabling controlled localisation, position fixing and—depending on the project scope—interventions directly at the object.
Why diverless search & recovery?
Diver operations often involve elevated risk, limited visibility and restricted bottom time. Diverless methods offer clear advantages:
- increased safety by avoiding diving operations
- systematic search even in poor visibility
- repeatable search tracks and area coverage
- objective, data-driven documentation
ROV systems allow controlled approach and project-scope-defined actions without unnecessary disturbance to the surrounding environment.
Methodology & technology
For search and recovery, SCANSUSTAIN uses a coordinated combination of:
- sonar for area and object detection
- video for visual identification
- navigation and position data for accurate localisation
Depending on the project scope, we will:
- locate and document objects
- assess position and condition
- perform preparatory or accompanying actions at the object
- or execute a structured recovery
The approach is adapted to local conditions on a case-by-case basis.
Typical use cases
SCANSUSTAIN search and recovery operations are commonly used for:
- lost or submerged items
- safety-relevant objects in waterways
- harbour and infrastructure areas
- environmental and waterbody projects
- pre-surveys ahead of clearance or construction works
Documentation & deliverables
All operations are documented in a traceable manner. SCANSUSTAIN provides:
- video and image material
- position-accurate location descriptions
- structured mission and results reports
This documentation forms a reliable basis for subsequent project decisions.
SCANSUSTAIN – precision in a project context
With diverless search and recovery operations, SCANSUSTAIN delivers a safe, controlled and data-based solution for tasks below the surface—aligned with project goals and scope.
