ICE-RESISTANT OFFSHORE PLATFORM Russian patent published in 2007 - IPC E02B17/00 

FIELD: hydraulic structures, particularly artificial islands mounted on piles or like supports, for instance, platforms on raisable legs, preferably adapted for oil production in shallow continental shelf, and installed directly on ground or to be fastened thereto by anchor connections.

SUBSTANCE: offshore platform comprises upper structure connected to support base by means of support columns and ice-protective fence installed on the support columns. The ice-protective fence is made as endless inclined assembly extending along platform perimeter in area of ice contact with the platform. The ice-protective fence encloses outer support column perimeters. Inclined assembly has additional ice-protective belt connected to upper part thereof and extending in direction opposite to inclined assembly inclination. The additional ice-protective belt is inclined at an angle of not less than 8° to vertical plane. The ratio between additional ice-protective belt height and inclined assembly height is not less than 0.08.

EFFECT: increased reliability and safety of offshore platform operation in ice conditions.
