In brief
The Léon Thévenin, a colossal vessel equipped with over 50 specialists, plays a crucial role in maintaining Africa's internet infrastructure, often restoring connectivity after significant outages caused by cable damage. With the team’s skilled efforts, this ship works tirelessly to bridge the digital divide in a continent increasingly reliant on technology.
The Léon Thévenin, a majestic vessel the size of a football field, navigates the African seas with a dedicated crew of more than 50 engineers and technicians, working steadfastly to maintain and repair undersea internet cables that are vital for communications across the continent. The importance of this ship became glaringly apparent after a series of internet blackouts last year, stemming from damaged cables, which plunged millions from major cities like Lagos to Nairobi into digital oblivion, impacting everything from messaging services to banking transactions. For over 13 years, the Léon Thévenin has been on a mission to restore connectivity after such disruptions. Shuru Arendse, a dedicated cable jointer from South Africa, shares his sentiment of pride: "Because of me, countries stay connected... I'm a hero because I save communication." His feelings echo through the crew aboard, who collectively recognize their crucial role in sustaining digital connections for myriad users.Undersea internet cables form an intricate network necessary for data transmission. Since most servers are housed outside of Africa, these cables link coastal cities to essential resources, essential to day-to-day operations online. These delicate systems, designed for durability, can face significant risks, primarily due to human interference. "Most of the time, it's people anchoring where they shouldn't and fishing trawlers scraping along the seabed," explains Charles Heald, head of the ship's remotely operated vehicle (ROV). Natural disasters also pose a challenge, particularly in regions with unpredictable weather patterns. For instance, the Congo Canyon is known for strong currents that can jeopardize cable integrity. Compounding the issue, last year saw the severing of three crucial cables in the Red Sea, disrupting connectivity across East Africa for countless individuals.The repair process usually begins with testing electric signals within the cable to identify faults. Upon confirming that the issue lies beyond local repair capabilities (typically 50 meters deep), crews from the Léon Thévenin spring into action. They can operate at depths exceeding 5,000 meters. The ensuing repairs can span over a week, although with modern rerouting methods, many users may remain unaware of the disruption.Once notified of a cable issue, the Léon Thévenin’s team readies to deploy within 24 hours, though logistical challenges can delay their response. After repairs, they meticulously lower the fixed cables back to the ocean floor, ensuring it's restored and setting the coordinates for future reference.Despite spending over half the year at sea, the crews, hailing from diverse backgrounds including South Africa, France, and the Philippines, embrace their essential roles. The emotional sacrifices are apparent, with crew members like Adrian Morgan reflecting on the personal toll of missing family milestones. But among their struggles is a strong sense of unity—the camaraderie onboard helps them navigate the challenges of their demanding jobs.As the crew continues their vital work, they remind us that they are the critical link connecting Africa to the global community. "We are the link between Africa and the world," asserts Chief Engineer Ferron Hartzenberg, embodying the pride and purpose that characterizes their mission on the Léon Thévenin.
