ROVs and HOVs

Trieste

Trieste (Bathyscaphe)

The Trieste was the first submersible to carry humans to Challenger Deep, in the Mariana Trench, in 1960.

HOV Alvin

HOV Alvin

Deep Submergence Vehicles (DSVs) are human-occupied vehicles (HOVs) with specific depth ratings. They are piloted by a human on board.

ROV Hercules

ROV Hercules

Remotely-operated vehicles (ROVs) are operated by pilots on a ship and do not have passengers. They are connected to the ship via a cable and are not autonomous like AUVs (autonomous underwater vehicles).
