Abstract
An ice platform suitable for multiseason use is constructed in a cold offshore region by accumulating ice on a portion of a floating natural ice sheet until the ice mass formed thereby becomes grounded on the marine bottom. A rigid wall element is driven through the ice and a preselected distance into the marine bottom so as to form a structural wall surrounding the ice mass. Subsequently an insulation jacket is installed over the top surface of the ice mass and between the ice mass and the wall. To dismantle the ice platform, the wall and at least part of the insulation jacket are removed to allow natural forces to restore the region to its natural state.
