World’s Toughest Ships | Floating Mega Mine: Treasure Hunt on the Ocean Floor | Free Documentary World’s Toughest Ships - Extreme Icebreaker: https://youtu.be/DhXQDz-Oo-4 Along the wild Atlantic coastline of southwestern Africa, a remarkable vessel carries out one of the most extreme industrial operations on Earth: underwater diamond mining. Originally built as a semi-submersible heavy-lift ship, the Dock Express 20 has been transformed into a state-of-the-art floating mining platform for De Beers. Beneath the waves, powerful crawler machines scour the seabed for diamond-bearing gravel, pumping material up through massive hoses to be processed aboard the ship in a complex network of sorting systems. Operating in rough seas, strong currents, and unpredictable Atlantic weather, the crew faces constant challenges as they search for precious stones hidden hundreds of feet below the surface. This is the story of an engineering giant repurposed for one of the toughest and most valuable jobs on the ocean floor. #FreeDocumentary #Documentary #ship ▬▬▬▬▬▬▬▬▬ Subscribe to Free Documentary Channel for free: https://bit.ly/2YJ4XzQ ▬▬▬▬▬▬▬▬▬ Free Documentary is dedicated to bringing high-quality documentaries to you on YouTube for free with the latest camera equipment used by well-known filmmakers working for famous production studios.
