Autonomous Underwater Vehicles: Challenges and Applications

Autonomous underwater vehicles (AUVs) are transforming the manner in which we discover and develop the underwater world. With manned crews onboard and robot systems far beyond the abilities of any living organism at the helm, AUVs are tailor-made for work that includes oceanographic surveys to constructing underwater hotels. In this article, herein, we discuss AUV applications, challenges, and opportunities, and how they’re reshaping the business in marine science and underwater tourism.

 

What are autonomous underwater vehicles?

Autonomous underwater vehicles, or AUVs, are underwater robots that are not operated remotely by a person. AUVs are equipped with sensors, cameras, and advanced navigation and can be used to gather information, map the ocean bottom, and even perform underwater construction work activities.

In contrast to remotely operated vehicles (ROVs), which are crewed, AUVs are present to get the task done. It is this autonomy that allows them to perform so efficiently at surveying offshore or hostile seafloor.

Applications of Autonomous Underwater Vehicles

There are quite a few different uses for AUVs. Some of the more interesting ones are described below:

1. Oceanographic Research

AUVs are also effortless to use while undertaking research on sea ecosystems, sea geology, and oceanic currents. AUVs can examine water samples, take the temperature, and show salinity levels, as well as monitor sea animals. AUVs, for example, have been deployed to survey coral reefs and climate change effects on sea ecosystems.

2. Construction of an Underwater Hotel

Submarine hotels have facilitated the application of equipment on the basis of their technical capability. Autonomous underwater vehicles are used in site surveys, structural surveying, and foundation building. They are highly efficient and can perform missions at extremely low depths and therefore are suitable to be used under such a situation.

3. Oil and Gas Exploration

AUVs are employed quite extensively by petroleum and gas exploration companies in prospecting within the areas of drilling, seafloor survey, and piping survey. AUVs find application in attempts to perform rescue operations such that the human divers will be rescued under deep water pressure, achieving the operation much more safely and efficiently.

4. Search and Rescue Operations

AUVs are used in wreck searching, missing persons, or lost cargo containers in crisis management. AUVs are fitted with sophisticated sensors and cameras and are able to withstand harsh underwater environments without any hassle.

5. Environmental Monitoring

AUVs are used in the monitoring of environmental pollution, oil spills, and marine ecosystem health. AUVs provide real-time feedback, and scientists and policymakers don’t need to make decisions out of data.

Problems Affecting Autonomous Underwater Vehicles

Although there are certain merits to employing AUVs, they are hit by a list of problems hindering them from being used extensively.

1. Navigation and Communication

Submarine navigation and communication will never be that simple. GPS can never be used underwater, and therefore AUVs would have to depend on the acoustic system, which would be less accurate. Submarine communication would be less and slower compared to aerial.

2. Limited Power

AUVs operate on batteries, and batteries have a shelf life. This reduces the lifespan they can be employed for a mission, and they need to be recovered or recharged periodically.

3. Expensive

AUVs are expensive to produce and operate. Material and technology employed in manufacture to withstand sea pressure render it expensive, thus beyond other organisations’ affordability.

4. Environmental Impact

Whereas AUVs are as limited as they have no long-term environmental harm effects, there will certainly be some effect on injuring aquatic life or ravaging delicate ecosystems. Wisdom and prudence are the best inhibitors of that.

Future of Autonomous Underwater Vehicles

AUVs also have a good future as a lot of research is being done to eradicate all the problems AUVs face now. Battery life, artificial intelligence, and communication underwater will be enhanced, and they will be more efficient.

For instance, scientists are working on developing how to create AUV swarms that will execute complex operations. It will be used to transform sectors such as underwater hotel constructions by AUV swarms constructing complex architecture.

Finally, one-riding submersibles also require AUV designs with immersive outputs. Imagine snorkelling over a coral reef or peering out of an underwater hotel from an AUV-worthy submersible!

Why AUVs Matter

Autonomous underwater vehicles are not only the new technology but also discovery and preservation instruments of the world’s oceans’ significance. AUVs are revolutionising our interaction with the ocean planet, from aiding scientific research to aiding underwater hotel tourism.

We will be using AUVs exclusively to aid in solving global issues like climate change, finding natural resources, and oceanic conservation.
