Underwater Drones

Whenever drones are mentioned, many tend to think of uncrewed aerial vehicles (UAVs). For maritime applications, however, remotely operated underwater vehicles (commonly referred to as underwater ROVs or underwater drones) are king. Underwater ROVs, like their airborne cousins, have become widely adopted in recent years. Just as UAVs have democratized the skies for many, industries and institutions across the globe whose work requires them to journey into bodies of water are looking to underwater ROVs as affordable solutions to access these depths.

What are underwater drones and ROVs?

As their name suggests, underwater drones or ROVs (short for remotely operated vehicles) are submersible, tethered, and highly maneuverable drones designed to operate underwater. Like aerial drones, underwater ROVs come in a variety of sizes. They can be outfitted to meet the unique needs of a multitude of maritime and subsea industries and applications.

Thanks to their versatility and cost-effectiveness, many agencies and organizations that traditionally relied upon expensive submarines and human divers to carry out their underwater operations have all but replaced them with underwater ROVs. These include but are not limited to asset monitoring, infrastructure inspections, public safety, search and rescue/recovery, defense and security, academia, and environmental conservation/preservation.

How are underwater drones being used?

Thanks to their compact size and 360° omnidirectional maneuverability, underwater drones are a safe and efficient way for maritime and subsea industries, agencies, and organizations to remotely evaluate and monitor their assets and conduct inspections while reducing both operational costs and human risks. Below are some examples of underwater ROVs’ real-world applications:

Aquaculture

Fisheries and other aquacultural enterprises can utilize underwater ROVs to remotely assess their fish farming operations. Traditionally, fish farmers would have to do so manually by making the dives themselves.

Shipping

Underwater drones enable shipping companies and shipyards to perform routine ship evaluations remotely and efficiently. They can also perform detailed hull inspections, shipyard activity monitoring, and damage assessments.

Offshore Energy

Underwater ROVs are a safe and cost-effective way for offshore energy companies to remotely carry out detailed industrial inspections. They can perform maintenance at offshore platforms without having to put engineers in harm’s way.

Utilities

Utilities providers such as power and telecommunications companies can deploy underwater drones to remotely assess and monitor subsea or submerged structures. Underwater drones can also track underwater pipelines, power cables, and fiber optic data cables.

Public Works

Underwater drones are ideal for agencies and organizations that maintain various water-related public works. They routinely carry out detailed structural and safety inspections of waterways and ports. They can also monitor submerged structures like bridge piers and abutments, dams, and other subsea platforms.

Search and Rescue/Recovery

Thanks to their ability to house variety of add-ons (such as buoyant robotic arms and other search and recovery tools), underwater ROVs are perfectly suited for a range of underwater search and rescue as well as salvage and recovery operations. Their ability to retrieve and carry much heavier payloads than human divers is an obvious advantage. In situations that require deployment of human divers, underwater drones can identify potential dangers to the environment before sending in human assets.

Defense & Security

Since you can operate underwater ROVs remotely from a distance, they can scout, locate, identify, and eliminate dangerous underwater threats that may be present within naval theaters of operations without the need to place human assets in jeopardy.

Academia

Since they are much more affordable than cost-prohibitive submarines, underwater ROVs greatly lower the barrier to entry for educators and students studying marine biology, naval engineering, and other maritime fields. Underwater drones allow educators to safely and efficiently conduct detailed subaquatic explorations to uncover the mysteries of the vast oceans.

Marine Conservation and Preservation

Thanks to their much smaller footprint and relatively quiet operation, underwater ROVs are also important tools for organizations working in marine conservation and ecological preservation. They facilitate the non-disruptive monitoring of marine environments, home to hundreds of thousands of aquatic species, as well as the diverse habitats that support them.
