Abstract
An offshore well drilling and/or production operation which is carried out on top of a layer of ice which extends over unfrozen water. A ring of thermal insulation is formed on top of the ice around the area of the drilling and/or production operation so that the ice thickness under the ring is thinner than the ice adjacent the ring thereby forming an annular depression in the underside of the ice. The depression will capture and hold any hydrocarbons or other fugitive materials that may escape under the ice in the area of the drilling and/or production operation.
