Hydraulic Power Extras: Remotely Operated Vehicles ben lee

If you’ve ever wondered how marine based remotely operated vehicles (ROVs) work then read on. The ROV is also known as an underwater robot and it can be controlled from above the surface of the water. They are connected via an umbilical cable that contains all the cables for the energy source, communications and information transfer.


In order to operate them, it’s necessary for all ROVs to have some type of visual capability, typically a camera. This makes it possible for those up top to be able to see under water and control the device as appropriate. Some ROVs are expected to operate at depths of up to 10,000 feet performing a multitude of activities and functions.


As the technology of ROVs and therefore their capabilities have advanced, the offshore gas and oil industries have relied on them to support their drilling and subsea construction tasks. They can make it possible to explore deep water in addition to working on development projects, all over the world.

Humans are able to submerge to limited depths due to the danger of deep water pressure. The ROV was developed to overcome these limitations and have now become an indispensable tool for the offshore energy industries.


The first ROVs were developed in the mid-1960s. This first concept was known as the Human Occupied Vehicle (HOV) but was fairly limited in its success due to the fragilities of humans, and not being able to travel to the depths of water required for successful task completion.


It was in 1966 that the US used an ROV to locate and recover a bomb off the coast of Spain and there was also a case when sailors were recovered from a sunken submersible off Ireland in 1973.


Since then, ROVs have been manufactured for extensive use in the offshore oil and gas industry. Technology has now advanced rapidly, making them more useful for a wide range of projects, drilling and cable related activities.
