A Brief Introduction To The Main Actor In ROV Operations

ROV is an acronym for Remotely Operated Vehicles which is, in turn, a form of underwater robot that lets the controller be located above water. In typical ROV operations, the robot is connected to the controller through an umbilical link housed on the top side containing an energy source powering the ROV and communications cables facilitating the transfer of information.

All ROVs are equipped with a camera like a visual device that lets the controller see things under the water in addition to other tools that are determined by the purpose for which the ROV is being used. As a matter of fact, certain types of ROVs have multiple manipulators that allow them to carry out different function even underwater as deep as 10,000 feet.

As the technology behind ROVs has developed it has become a friend for the offshore oil and gas industry. The latter relies on ROVs to support their drilling and undersea construction activities.

Different Types of ROVs

The size of an ROV can range anything from between bread box to that of a large van. Its functionality too is similarly varied, from making observations of undersea environments to having multiple agile arms which let the ROV carry our several functions underwater.

But ROVs are used mainly for inspecting and observing subsea environments. The Small Electric Vehicles are the smallest avatar in which ROVs are found. They carry one camera at no more than 300m deep under water.

There are several bigger siblings of the Small Electric Vehicle like the High Capability Electric ROV. Through the introduction of these ROV variants, the operating depth possible is boosted to 6096 meters of 20,000 feet. Their major impediment is being equipped with cameras solely. Their functionality also suffers because of the limits imposed by their electricity supply system. This variant of ROVs is mainly used for military and scientific purposes. As they cannot perform any other task except observation they are of little use oil and gas related exploration and functions.

With the next progressively bigger variant of the ROV the Work Class Vehicle,the robot has electrical and hydraulic power and is able to get a considerable amount of work done in the undersea environment. Granted, the lift abilities and the payload capacity is limited but its manipulator can perform as many as seven functions, in addition, the grabber’s five functions. This range of ROVs is mostly put into use in the inspection of pipelines and in supporting construction and drilling subsea.

If you have some really heavy work to do at depths of 10,000 or 3000 meters, then the Heavy Work Class Vehicle was created keeping in mind your needs. It boasts of 100-250HP and can lift the weight of 11,025 pounds. Not only that with their several grabbers and manipulators they are able to complete installations in the depth mentioned and undersea tie-ins.

The tech behind ROVs like everything else is also evolving the future of the industry the AUV or Autonomous Underwater Vehicle is what industry experts are looking forward to next.
