The $15,000 Robotic Cleaning That Removes a Ship's Sludge

Short | 02:01

The remote-controlled robot that cleans the hull of a ship as big as Tonsberg costs $15,000 for its services. But with a soccer field's worth of sea guck to be removed, it certainly earns its keep.

More About This episode

From exotic sports cars to helicopters to locomotives, Tonsberg can carry anything on wheels. She's one of the largest roll-on/roll-off vessels ever constructed, a 17-story warehouse on the waves. Follow her on her latest delivery route, a four-port, 15-day mission that will take her across the Atlantic Ocean. With a giant payload of 3,000 cars, a giant crane, excavators, and even yachts, Tonsberg must work her way through tight channels, shallow waters, and even a tropical storm, delivering everything on time, and without a scratch.
