ROV’s or remotely operated underwater vehicles are robots that accomplish underwater tasks for crews. The crew is mostly on the surface of a boat to which this ROV is tethered. A beneficial product the same helps in search or recovering items. 

Inspection, repair of equipment, scientific analysis and cable laying among other benefits. The ROV’s that are sent in deep water are tethered by a stable system to avoid any discrepancies and here we tell you some features and the types of Underwater ROV’s that you should be aware of.

Features 

The ability of an ROV is measured by what kind of instruments is attached to it. On an outset, an ROV can have a camera, lights, and aquatic thrushers on it without any problems. Some other instruments that you would see predominantly on an ROV are sonar, magnetometers, mechanical manipulators, other camera types, cutting and shearing tools.

 Apart from that, you can also have other instruments that help in monitoring the environment and its characteristics. Electrical systems can be outfitted in the watertight compartments filled with oil. On the other hand, high power tools receive power from hydraulic pumps. 

Types of ROV’s 

There are five types of ROV’s that you can choose from and here is a brief detail of each:

Small electric ROV’s- These are the smallest of ROV’s that can be used. They do not have a hydraulic pump with them. Hence, they can only delve into depths of 1000 feet at maximum. You can use these ROV’s only to make any observations hence making their purpose limited.

High capability electric ROV’s- They also do not have a hydraulic pump however you can use them for purposes like deep-sea observations and deep-sea illuminations. Most of the high capability ROV’s can go into depths of 20000 feet so they are considered suitable for military and scientific industries.

Work class ROV- This type of ROV has a small iteration of hydraulic pump use. It can be modified to be used for specific applications and is used for deep-water drilling and any kind of construction work. The depth limit, in this case, is 12,000 feet at the maximum.

General class ROV- The general class ROV is run with electricity but has primary features like manipulator and sonar. It also has a five-horsepower motor to provide underwater movement.

Heavy class ROV- They are supposed to be the most useful ROV as such. A heavy class ROV is provided with multiple functionality manipulators and the motors can produce several hundred horsepower energy. Though the working depth is limited to 10,000 feet, they can lift to 12000 lb weight.

Conclusion

A remotely operated underwater vehicle offers you more scope than any other. It is a quick method to get your underwater tasks handled in the most efficient manner possible. While purchasing one make sure to do your share of research so that you are not fleeced with an average quality product. The ROV you buy should give you a benefit of all the above features and tackle your tasks with utmost efficiency.
