FIELD: shipbuilding.
SUBSTANCE: invention can be used in designing structures to be used in freezing seas. Offshore floating platform for drilling and/or producing and storing in ice conditions comprises outer side of hull including at least two additional symmetric sections. First section is located on the upper section and has the shape of polygonal regular prism or cylinder with outer diameter not more than 0.9 of section diameter on which it is located. Second additional section is located within the section of hull outer side upper section with back taper, which is made with double knuckle in the form of two consecutive cone-shaped sections with reverse located along the platform axis. Upper section has angle of inclination of horizon about 30 degrees, and lower - nearly 50 degrees. Total height of section with double knuckle is not less than rated ice thickness in water area of the corresponding platform operation area.
EFFECT: possibility to reduce impact of ice loads on platform and improved navigability.
