Abstract

An improved barge hull for offshore drilling rigs is disclosed. The invention comprises a channel in the bottom of a barge hull extending from the bottom of said barge hull to the back of said barge hull for directing the flow of water under said barge hull to the back of said barge hull in order to disrupt the relative hydrodynamic stability of a body of water immediately behind said barge hull and thereby decrease the towing resistance of said barge hull.
