call the only ship that has been repairing them for more than a decade

That an underwater cable breaks (or someone cut it) can happen anywhere. There is amazing ships dedicated to deployment and repair of this critical infrastructure in our hyperconnected world. However, when it happens in Africa there is only one ship that can answer the call at any time. Is called Leon Thevenin and has been in operation for more than forty years.

The ship. As they say in Rest of WorldIn the world there are 62 cable repair ships that are always available, but in Africa there is only one. The Léon Thévenin is part of the fleet of Orange Marinea subsidiary of the French operator Orange, and for thirteen years has been in charge of all repairs from Ghana to Madagascar. It is 107 meters long and the crew that operates it is 60 people. It also features a remote submarine and a small work boat. According to the official ship record, It is capable of making repairs in extreme weather conditions, in both deep and shallow water.

African cables. In this map We can see that the continent is surrounded by countless cables that provide connections to both its inhabitants and data centers and ground stations. Among the most notable is the ‘Peace Cable’ connecting Singapore to Kenyathe West African cable system and the Alphabet Equiano that go from Portugal to South Africa. The cable also stands out 2Africa which with its 45,000 kilometers is the longest in the world; It connects from the United Kingdom, goes all the way around the African continent and ends in India. And there are many more.

Accidents. Cables deteriorate, they can also be damaged after storms or if a ship drops anchor and drags it. Many times the cuts are intentional, but they usually occur in other places in increased geopolitical tension like Taiwan either the baltic sea.

In March 2024, much of the west and center of the continent was left without connection due to simultaneous failures in several cables. The Léon Thévenin was in charge of returning connectivity to millions of people. It has not been the only case. In recent years the ship has been having a lot of work because the Congo Canyona huge underwater canyon that extends 280 kilometers into the Atlantic, is suffering many landslides that have affected several cables.

A great responsibility. It is estimated that 99% of the world’s internet traffic travels over submarine cables. If a cable breaks, it can leave millions of people without connectivity. Furthermore, in the age of AI, connectivity is even more important because it connects the infrastructure that makes it work. The price to pay for the Léon Thévenin crew is spending very little time with his family. Sometimes they rest for a month, the problem is that if a breakage occurs they are the only ones who answer the call.
