Imagine lifting 900 tons of ship, then putting it down - v-e-e-ery carefully

Bath Iron Works in Maine recently broke its weight-lifting record when it hoisted a 900-ton superstructure 89 feet in the air, then lowered it atop a DDG 1000 Zumwalt-class destroyer.
Bangor Daily News has the story, with a video. It notes "The downward force on the cranes was so intense the ground beneath them was reinforced to distribute the load."
The story gives the weight in pickup-truck equivalents ("5,200 full-sized Ford pickup trucks") but not in the more enjoyable elephant equivalents, a unit of measurement that fascinates New Scientist magazine.
