Knowledge & Authority Hub
Seven thematic clusters for engineering offices, authorities, operators, expert witnesses and research. Technical articles, comparisons, decision aids and foundations — without marketing fluff, without gated content.
The ScanSustain knowledge hub gathers what we explain again and again in briefings, to expert witnesses and in authority meetings. Every entry follows the same standard as our missions: precise, traceable, no detours. The hub connects expert knowledge directly to matching services and sectors — so you move from question to solution.
The hub is organised into seven topic areas. Each cluster bundles technical articles, foundations and directly linked services.
Foundations and practice of ROV-based visual inspection of structures, pipelines, basins and vessel structures. When ROV instead of divers? What does a robust inspection data package look like?
Matching service: ROV Inspection
When is video enough, when does sonar become a required tool? Multibeam, side-scan, profile sonar — operating limits, resolution, coverage. Why turbid water is no excuse for bad documentation.
Matching service: Sonar & Scanning
Bathymetry, photogrammetry, point clouds and reference models. Which methods deliver which accuracy — and which exchange format fits which downstream processing?
Matching service: Survey & Mapping
What makes an inspection report authority-ready? Which components belong in an inspection file? What does an evidence-grade raw data handover look like?
Matching service: ROV Inspection · Sector Authorities & Municipalities
How does a one-off inspection become a monitoring programme? What is a delta comparison, how is a baseline defined, and why reproducibility matters more than technology?
Matching service: Monitoring & Recurring Inspection
Non-invasive capture of substrate, vegetation and structural features. Use in EIA procedures, protected-area assessments and research. Why baseline quality determines procedural outcomes.
Matching service: Habitat Mapping · Sector Environment & Conservation
Raster-based search strategies, coverage evidence, position determination and evidence preservation. What distinguishes a documented search from uncontrolled wandering?
Matching service: Search & Recovery · Sector Insurance & Expert Witness
Quick orientation between methods and terms — compact, no detours.
A finding that can be used in inspection files, expert reports or court proceedings without rework. Includes time, position and method reference.
A methodology that follow-up missions can traverse identically. Prerequisite for every robust time series.
Structured summary of inspection results with image references, classification and action recommendations. Replaces the verbal diver protocol.
The first audit-grade capture of a structure or habitat. Forms the comparison basis for every later delta mission.
Juxtaposition of two identically captured states to identify change. Core of the monitoring programme.
Method protocol with route, sensors and reference points — so follow-up surveys can reproduce the same dataset.
Chronological list of all technical articles and news entries. Every article links into the matching service or sector context.
