Abstract
The device comprises an assembly of three principal components, a member for embedding in the rear wall of a tabular iceberg at some depth below the water line, a support structure projecting therefrom and a propulsion unit. It preferably includes a shield to transmit the thrust to a sufficiently large surface of the iceberg wall to avoid creep problems. The propulsion unit may be an electric motor.
