Observer is a small remotely operated underwater robot providing camera imagery to its operator. Subsea Tech offers several equipment levels within the same product family. The vehicle has three thrusters and can operate from batteries or a surface power supply. Camera edition, connections and supplied tether length differ with the selected set. Figures here come from the official Observer brochure and describe the vehicle rather than a complete transport package. For inspection, the selected cable should follow the route and the imagery should match the object being assessed. Listed battery duration is a maximum; project duration and charging arrangements should reflect the actual mission.
