18. Special Equipments for Construction
(Plough)
The Plough is designed for the installation and burial submarine cables at same time to protect the cable

19. Special Equipments for Construction
(ROV)
Remotely operated vehicles (ROV), plough typed vehicle, can be used for the difficult working area like the junction of cables and of re-burial working after repairing the present cables.

21. Visualise - 3D again
Generic repair in 4000 metres of water
Not enough slack - need to cut
drive slowly across the line of the cable
allowing time for things to settle

22. Cable hooked - picking up

23. Cable cut off the bottom

24. Recovering graps - going round again

25. 1st holding drive with new grap
depth of water from the cut

26. Cable hooked - picking up

27. 1st end buoyed off
Ground rope and anchors
Second holding drive has been done

Merely just looking at the connectivity available from systems immediately around Africa, through SAT-3/WASC/SAFE, Atlantis-2 and SMW3, African countries can have direct broadband cable access to at least 50 countries – ranging from South Americas, Europe & Asia, Australasia, etc.
In fact direct cable connectivity is available to all continents of the world – enabling business and to set up operations with the same measure of connectivity available to the global base as with any other first world region of the world.
