An Underwater Remotely Operated Vehicle (ROV) is a mobile robot designed for aquatic work environments. Remote control is usually carried out through copper or fiber optic cables. A human operator sits in a shore-based station, boat or submarine bubble while watching a display that shows what the robot “sees”.
ROV machine contains main frame that hold all the components such as :
- Motors with special fans used for moving the machine at all directions.
- Robotic arm to catch, hold, or make some tasks.
- Air tank used for floating and drowning.
- Video camera to record and view image under the water.
- Floodlights which are very important for lighting.
- Navigational sensors and Processors.
The main functions of the ROV is maintenance and repair of oil pipelines by :
- Turn off a valve to stop the flow of oil through the pipeline.
- Examine the gauge dial to determine the pipeline oil pressure.
- Measure the length, cut, remove a section of corroded pipeline and return it to the surface.
- Install and secure an adapter flange over both cut ends of the pipeline.
- Insert a hot stab to simulate injecting corrosion prohibiter into the wellhead.
- Use a map to determine the pathways of flow through a pipeline system.
- Turn valves to ensure that oil will flow through the specified pathway.
- “Push” water through the pipeline system to verify that oil will flow through the correct pathway.
