Abstract
A method and apparatus for constructing an ice structure in deep (e.g. 50 feet) waters having a moving sheet of ice on the surface. A rubble generator is positioned in the path of the ice sheet and a portion of the marine bottom is artificially raised adjacent to and on the upstream side of the generator by submerging at least one berm onto the marine bottom. The height of the berm is such that it artificially raise the marine bottom to a depth which is less than the original keel depth of a pile of ice rubble formed when the moving ice sheet interacts with the generator thereby the rubble pile will be spontaneously grounded and immobilized on the berm. Once the rubble pile is grounded, additional ice (e.g. spray-ice) is accumulated thereon to complete the ice structure.
