Confined spaces access caused 10 deaths each year for more than 20 years in the maritime industry.
Recently in Europe, we inspected a cable layer's water ballast tanks with our drone⚓
As you can see it would have been difficult for an inspector to get there.
The high levels of CO2 and H2S would have require to ventilate tanks for hours before allowing safe entry.
Therefore, the drone inspection allowed us to complete our task quickly, remotely, and securely.
