In recent years, fish farms have increasingly started using underwater ROVs (remotely operated vehicles) for cleaning the nets that enclose their fish pens. A relatively new one, the StealthCleaner, has a unique triangular form factor.
Manufactured by Norwegian ROV company Kystdesign, the StealthCleaner is connected to a surface-located support vessel or shore-based control station via a power/communications umbilical cable.
Utilizing real-time feeds from four onboard cameras (which are assisted by LED spotlights), the operator starts by remotely piloting the ROV through the water, over to the pen. They then guide it back and forth, in successive passes along the net.
