Abstract

An offshore structure, such as a drilling platform, which is able to withstand the ice forces imposed thereon by impinging ice sheets and other larger masses of ice is provided with an upper conical portion 6 coaxially positioned relative to a lower conical portion 4. The surfaces forming the walls of both the upper and lower conical portions are inclined at an angle to the horizontal to receive the ice masses moving into contact with the structure. The angle of inclination from the horizontal of the surface of the upper conical portion is greater than the angle of inclination of the surface of the lower conical portion and the maximum cross-sectional diameter of the upper conical portion is no greater than that at the top of the lower conical portion, i.e. the minimum cross-sectional diameter of the lower portion. <IMAGE>
