ICE ISLANDS AND METHOD FOR FORMING SAME

摘要

"" An ice island for use in offshore operations in cold waters includes an operations pad and a surrounding containment barrier, the bases of which are grounded on the marine bottom. The island is constructed by accumulating ice in confined areas defined on a sheet of native ice until the mass of the accumulated ice causes the ice underlying and adjacent to the confined area to be depressed with respect to the main body of ice and be grounded on the marine bottom.
