Abstract
An arctic drilling barge to perform offshore activities in the shallow water, fast ice regions of the arctic seas. Optimal ice interaction is obtained by shaping the hull of the barge in the form of an upright frustum. Ice which does adhere to the barge is detached and melted by circulating fluid through a plurality of interior hull compartments next to the hull sidewalls of the barge.
