In aquaculture, maintaining the integrity of underwater infrastructure is essential to protecting stock, avoiding environmental risk, and sustaining operational uptime. Containment nets, fish pens, and mooring systems are constantly exposed to mechanical stress, environmental forces, and biological fouling. Regular inspections are critical—but underwater visibility challenges often limit the effectiveness of traditional video systems.
That’s why Voyis brought the Discovery Stereo Camera to Aqua-Cage Fisheries in May, demonstrating how high-resolution optical imaging and real-time 3D data can elevate structural inspections from subjective visual checks to quantifiable, confidence-driven assessments.
Clarity Where It Matters Most: Net Inspections
Net integrity is the first line of defense in aquaculture. Any breach—whether from abrasion, predator damage, or wear over time—can lead to devastating fish escapes or biosecurity issues. During the demo, we used the Discovery Stereo Camera to perform detailed visual inspections of the containment nets, even in the low-visibility conditions typical of active fish farms.
The true-colour, high-resolution imagery clearly captured fine structural details, demonstrating how the system can detect early signs of wear—such as frayed mesh fibers, small holes, or biofouling buildup—if they were present. But seeing these details is only part of the value. With stereo imaging, operators are also able to take precise measurements in real time—like the length and width of any openings, or the diameter of specific features—turning the inspection into a repeatable, data-driven process. In this case, the inspection confirmed structural integrity, but the ability to quantify potential issues is key to proactive maintenance and long-term asset reliability.
Accurate Pen and Mooring Assessments
Beyond nets, the broader infrastructure—pens, brackets, floats, and mooring connections—was inspected for signs of corrosion, misalignment, or mechanical fatigue. These are often difficult to assess without diver intervention or manual measurement. However, the Discovery Stereo Camera enabled remote measurement of structural elements, such as confirming the angle of a misaligned brace, or checking the spacing between mooring clamps.
This measurement capability proved especially valuable when looking for early-stage structural issues that might not yet be critical but warrant monitoring. The ability to capture both qualitative imagery and quantitative data ensures that inspection records are not only visual but also metric—enabling trend analysis and condition tracking over time.
Inspection Efficiency and Data Confidence
One of the most significant operational benefits demonstrated was the efficiency of data collection. Traditional inspection approaches rely heavily on diver availability and subjective video interpretation. The Discovery Stereo Camera, deployed on a compact ROV, captured high-quality footage and real-time 3D measurements in a single pass, reducing the need for rework or multiple inspection stages.
Operators could verify the condition of assets on-site, make informed maintenance decisions immediately, and record inspection data with a level of repeatability that supports long-term maintenance planning and compliance reporting.
Building a Resilient Operation
Every aquaculture site faces unique environmental stressors and structural challenges. But what they all share is the need for accurate, efficient inspection tools that help maintain safe and productive operations. The Discovery Stereo Camera’s ability to deliver clear optical visibility paired with precise 3D measurements offers farm operators a new level of control over their infrastructure—detecting small issues early, validating structural changes over time, and reducing the risks associated with undetected damage.
