The SEARACK frame is metal free, neutral buoyancy, scalable and flexible frame to mount on any ROV, each holding up to 4 FGM3D UW sensors – making it the ultimate universal ROV frame. The flotation panels can be inserted, increased or removed one by one to adapt to overall ROV setup. As the frames are combinable – either fixed or even with hinges to keep the low logistics approach and to fit through A-frames – larger survey width or sensor spacing can be achieved without jeopardizing maneuverability and payload of the ROV.
