Many of the tasks assigned to work class ROVs – or human divers – is shallow (less than 300m) and involves searching, inspecting, or surveying underwater. These tasks are ideally suited to GNOM ROV technology. Smaller, lighter, ROVs that consume very little power can be deployed from many different areas or rigs and ships. Since they have very little mass, they can be safely used on comparatively delicate machinery without fear of damage.

Launching simply involves heaving the submersible by hand into the water. They can be deployed in sea states that would be too dangerous for larger machines. Their thrust to weight ratio for a small tether means that mini ROVs can be handle more current than most work class ROVs in shallow waters.
