Computer Vision for Subsea Inspection

Flag corrosion in ROV footage. Get the compliance report.

Ecodetect watches every frame of your underwater survey video, marks each anomaly by location and type, and drafts the inspection report, so engineers work on findings, not playback.

Figures drawn from discussions with offshore inspection teams in our early-access programme.

What we detect

Full-spectrum anomaly detection, built for offshore infrastructure

Trained on annotated ROV footage from real offshore wind and marine inspection programmes.

Corrosion and Coating Loss

Surface oxidation, pitting, and coating failure detected frame-by-frame across monopiles, J-tubes, and transition pieces.

Cathodic Protection Wear

Anode depletion and zinc bracket degradation identified without specialist divers or contact measurements.

Marine Growth and Fouling

Biofouling extent mapped and quantified on structural surfaces, with thickness-trend output across repeated surveys.

Crack and Fracture Detection

Linear surface defects detected at visibility limits, with confidence scored per frame and position tagged to GPS coordinates.

Cable and J-Tube Condition

Cable sheath abrasion, J-tube wear markers, and clamp displacement tracked along the full cable route.

Report-Ready Anomaly Records

Every detection exports with timestamp, depth, GPS position, frame reference, and regulatory classification built in.

From footage to compliance

Draft report in hours, not weeks

The footage is on the vessel within hours of the survey. The inspection report that turns that footage into a compliance submission has historically taken six to twelve weeks.

Ecodetect closes that gap. Upload the ROV video, and the platform returns a structured anomaly log and a compliance-formatted draft report within hours of processing completion.

How operators use it

Built into the inspection programme, not bolted on

Ecodetect fits the existing ROV inspection workflow. No new survey equipment, no re-training dive teams.

1

Upload ROV footage from vessel or shore

Standard .mp4 or .avi survey files. Vessel-side upload via browser, or automated transfer from the operator's data pipeline.

2

Computer vision analyses every frame

Detection models trained on annotated North Sea and offshore wind survey footage run at 1.4x real-time speed, scoring confidence per anomaly type.

3

Surveyor reviews the structured anomaly log

The flagged frames and classification list are reviewed and confirmed by the inspection engineer, who adds professional sign-off.

4

Compliance-ready report exported

The final PDF report includes all anomaly records, positions, confidence ratings, and the regulatory classification your certifier requires.

From the early-access programme

Reducing post-survey reporting from days to hours

Across 4 ROV surveys in our early-access programme, Ecodetect reduced post-survey reporting time from an average of 11 days to under 18 hours. (Internal timing data, early-access pilot cohort.)

"We were getting footage back in 48 hours and waiting ten weeks for the report. With Ecodetect, the anomaly log was in our portal the same week as the survey. The sign-off process went from a bottleneck to a formality."
