FacebookTwitterEmailLinkedin As part of its Superstructures: Engineering Marvels series, National Geographic has published a video regarding the GPO Amethyst, a semi-submersible heavy-lift ship capable of transporting some of the largest and heaviest cargoes in the world. As explained in the video, at first glance, it may look like a conventional cargo ship, but its capabilities are extraordinary. The Amethyst is not just large. It is one of the biggest ships in the world, designed to carry cargoes so massive that ordinary ships could never hope to manage them. It is a hybrid of cargo ship and submarine, able to partially submerge itself to lift and transport colossal loads with precision.
