How do undersea cables get repaired?
How do undersea cables get repaired?
The ROVs can’t operate in deep water due to the increased pressure, so to fix a deep water cable, the ship has to use a grapnel, which grabs and cuts the cable, dragging the two loose ends to the surface. If needed, one end can then be hooked to a buoy and the other end brought on board.
Where does India get internet?
As of May 2014, the Internet is delivered to India mainly by 9 different undersea fibres, including SEA-ME-WE 3, Bay of Bengal Gateway and Europe India Gateway, arriving at 5 different landing points. India also has one overland internet connection, at the city of Agartala near the border with Bangladesh.
Are undersea cables buried?

How are cables repaired in the ocean?
Note this series of slides to be replaced by video Different repair methods are used in different depths and conditions One common method starts with the ship dragging a cutting grapnel to cut the cable For cables buried deeper than 1 m into the seabed, multiple cutting runs may be needed to find the cable 13
What is the marine installation process for submarine cables?
Once the assembled system has been loaded aboard the cable ship and has been tested satisfactorily, the marine installation process can commence. Laying installation means that the submarine cable ship conducts the laying of the submarine cable on the seafloor according to design routing and slack control requirements.
How does the ROV find the repaired submarine cable?
The ROV finds the repaired submarine cable by detecting the 25 Hz low-frequency signal, uses the water gun to perform the burial operation, until the submarine cable is buried in the seabed, and then inspects whether or not the buried depth is enough.
