Surface-controlled ROV and diver inspection of submerged assets, with sonar/video surveying, geospatial deliverables and configured repair/cleaning functions.
Technical detail
Core features
Surface-controlled sonar/video inspection and owner-coordinate GIS/CAD XYZ outputs
Supplier longest tunnel tether example 14 km; position/drift budget remains separate
Configured ROV grout, sediment removal and commercial diver/construction functions
Method-specific class procedure and certificate scope
ROV inspection
Sonar mapping
Underwater engineering
Asset condition assessment
Use & integration
Recorded applications
Submerged tunnels, pipelines, outfalls and infrastructure inspection
Configured underwater repair and maintenance
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Commercial services with independent municipal award, annual buyer payment and historical ROV execution. Issued diver/class and management certificates have method/site limits. ROSE development and defence exploration do not establish completed operational capabilities.
Commercial availability
Define asset access, depth/flow, sensors, tether/navigation/accuracy, tooling, operators, site and applicable class procedure. Confirm current equipment availability and accepted deliverables; historical fleet ratings are not a current inventory.
Integration and verification
Readiness
A technology readiness level is not established by the reviewed public sources.
The described underwater measurement, inspection or support function can contribute to undersea characterization; this derived fit does not establish defence adoption.
This is a reviewed public-source assessment. It is not procurement eligibility, endorsement, customer interest, or classified demand.

ASI describes WireScan HQ as a wire-guided laser measurement system for gate and stoplog slots above and below water, operated by a two-person team. Example accuracy is 2 mm on steel and 5 mm on concrete, subject to the survey configuration. It complements diving and ROV services rather than constituting an autonomous ROV.
