Mighty Ships - Season 3, Episode 03: Cristóbal Colón

Cristóbal Colón represents a whole new breed of massive construction vessels. She's a hi-tech ocean dredger, twice the size of her closest competitor, and can store over 1.5 million cubic feet of sand on board. Follow this super-sized ship on her first mission: dredging and delivering 88 million cubic feet of sand from the sea floor to a construction site in Germany. It's an assignment no other dredger can handle, but up against a tight deadline and Germany's worst winter in 100 years, this job may even be too big for the biggest dredger ever built.
