SubC Imaging explores how ROVs are categorized into distinct classes, each designed for particular operational depths and specialized roles in marine exploration and industrial tasks. Read more >>
Remotely Operated Vehicles (ROVs) are essential instruments in underwater research, allowing access to areas too hazardous or remote for human divers. These engineered systems support scientific missions and data collection in some of the most extreme oceanic environments.

Built for demanding deep-sea missions where diver access is impossible, these ROVs are a mainstay in offshore energy operations and deepwater archaeological work. They operate at depths between 3,000 and 6,000 meters.
Light Work Class ROVs
Used in both mid-depth and deep-sea settings, these systems frequently handle inspection and maintenance jobs. They support a range of add-ons, including laser scanners and advanced sensors, and typically function within 1,000 to 3,000 meters below the surface.
Observation Class ROVs
Compact and versatile, these vehicles are deployed in shallower environments like coastal regions, lakes, and rivers. Equipped with sonar and configurable sensor packages, they are generally rated for depths of 300 to 1,000 meters. The Rayfin Micro subsea camera by SubC is well-suited for this class.

Micro or Mini ROVs
The most compact of the ROV classes, these are ideal for close-up inspections in tight or shallow underwater spaces, such as pipelines and submerged structures. They usually operate at depths ranging from 100 to 300 meters.
The full article from SubC Imaging takes a closer look at how ROVs operate, details each class, and explores their growing impact on underwater discovery and analysis.
