Iceberg Mover. Because icebergs can cause tragic accidents if they lie along the route that a ship plans to travel on or run into an oilrig, oil companies have devised a way to clear them out of their rigs’ ways. Enter the iceberg mover. Using a specially-constructed tugboat, the iceberg mover circles the iceberg with a huge rope, and then moves it to a safe location. This job isn’t for wimps. Icebergs can flip during the towing process, cutting the tugboat in two.
