Underwater Photogrammetry that Delivers Measurable Results
Underwater photogrammetry combines accuracy, efficiency, and visual clarity in a way standard video and sonar often cannot. Using IVM technology, we capture high-resolution imagery and convert it into true-texture 3D models that you can measure, analyse, and share.
Unlike conventional video, the output is not just footage, it’s usable geometry with quantifiable data for metrology and engineering decisions. It also reduces time offshore by replacing repeat passes and complex acoustic set-ups with a faster, cost-effective capture and review workflow.
Independent. Non-Contact. Millimetric Accuracy.
Our Hydro Series cameras operate as a fully independent, non-contact measurement system. No additional sensors, ladders, markers, or navigation aids are required, enabling true free-flight inspections without physical reference points.
Compared to sonar or acoustic methods, underwater photogrammetry delivers the millimetric accuracy required for detailed dimensional control and integrity analysis. High-resolution digital stills also provide greater clarity and measurement reliability than conventional video capture.
Why photogrammetry over other inspection methods?
Photogrammetry isn't a single-purpose tool. Across offshore renewables, oil and gas, and marine civils, it solves a range of problems that traditional inspection methods handle poorly, or can't handle at all. Here are the four most commercially significant applications.
Mooring chain measurement
Manual calliper measurements by divers are slow, inconsistent, and hard to justify on safety grounds. Photogrammetry replaces them with precise, repeatable dimensional data — surveyed weekly, monthly, or annually — so wear rates are tracked over time and failing chain sections are identified before they become a problem.
- Replaces manual calliper measurements with accurate, repeatable dimensional data
- Full 3D model and annotated imagery included in every deliverable
- Weekly, monthly, or annual survey cadence enables trend analysis and wear-rate tracking
- Data supports tension estimation and structural modelling
- Supports integrity management programmes and regulatory reporting
- No diver required
Freespan inspection
We measure freespan height above the seabed to submillimetric accuracy — and because surveys are fully repeatable, we can tell you whether a span has grown since the last inspection. Freespan geometry can also be used to estimate tension loading on the cable or pipeline, giving engineers the data they need to decide whether intervention is warranted.
- Submillimetric height-above-seabed measurement
- Freespan length tracking across repeat surveys
- Identifies whether a span is growing between inspections
- Data supports tension estimation and structural modelling
- Integrates with asset integrity programmes
Crack detection and monitoring
Photogrammetry offers a non-contact alternative to eddy current and ACFM for subsea weld inspection — identifying surface-breaking cracks, characterising their geometry, and tracking progression between surveys without direct sensor contact. This is a developing application with strong early results, and one worth discussing if you’re planning a weld inspection campaign.
- Non-contact surface crack detection and characterisation
- Full 3D model captures weld geometry in detail
- Repeat surveys allow crack progression to be monitored over time
- Potential to reduce reliance on ACFM and eddy current in appropriate applications
- Applicable to offshore renewables, oil and gas and marine infrastructure
Cable integrity and movement monitoring
We deliver photogrammetric cable monitoring surveys for RWE at Triton Knoll, repeated twice a year for the life of the asset. Each survey is compared against the prior inspection and the installation baseline — capturing lateral movement, burial change, and exposure risk so operators can forecast maintenance needs and act before problems develop.
- Precise cable position, condition, and movement data from each survey
- Twice-yearly or custom survey cadence matched to asset requirements
- Direct comparison against installation baseline and prior surveys
- Identifies lateral movement, burial change, and exposure risk over time
- Supports long-term maintenance forecasting and investment planning
- Baseline data transferable across similar assets and sites
Frequently Asked Questions
Learn more about our Photogrammetry solutions
Common questions about our IVM-powered photogrammetry process, deliverables, accuracy, and how the data can be used for inspection and engineering decisions.
What is photogrammetry used for?
Photogrammetry is used to create accurate 3D models from high-resolution imagery, allowing assets to be measured, inspected, and reviewed digitally. It supports engineering analysis, retrofit planning, damage assessment, deformation checks, and condition reporting without relying solely on manual measurements or legacy drawings.
How accurate are your 3D models?
Using IVM technology, our photogrammetry models provide reliable, measurable data suitable for engineering review. Accuracy depends on factors such as access, environmental conditions, surface texture, and scale control, but the output is designed to support practical measurement, spatial validation, and technical decision-making.
What deliverables are included in a photogrammetry project?
Deliverables typically include a shareable interactive 3D model, high-resolution annotated images, key dimensional measurements, and exportable files compatible with common engineering and CAD software. A summary report can also be provided to support internal review or third-party submission.
Can the 3D models be used for engineering and fabrication planning?
Yes. The models provide measurable geometry that can be used for fit checks, retrofit planning, spatial verification, and collaboration between engineering and fabrication teams. Exportable data formats allow integration into existing design workflows.
Does photogrammetry reduce the need for repeat site visits?
In many cases, it does. Because the asset is captured in detail and converted into a measurable digital model, teams can review, zoom, annotate, and take additional measurements remotely. This reduces uncertainty and can minimise the need for repeat physical access.
Is photogrammetry suitable for confined spaces or underwater environments?
Yes. IVM technology can be deployed in confined spaces and underwater environments, subject to access planning and safety controls. This makes it suitable for tanks, hull structures, subsea assets, and other areas where traditional measurement methods may be limited.
