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

FIELD: hydraulic structures, particularly marine platforms to be operated in ice circumstances.

SUBSTANCE: ice-resistant platform comprises support base, column and upper building, as well as ice barrier installed on the platform in area of ice action upon the platform. The barrier comprises enclosing wall with stiffening ribs and heat-exchanging device adapted to circulate heat-carrier. The heat-exchanging device is made as a number of channels arranged between stiffening ribs and defined by at least two sealed cavities. One cavity is adapted to circulate heat-carrier, another one is used as air insulation means. Heat-carrier circulation cavity adjoins inner wall of ice barrier. Air insulation cavity is defined by adjacent partition located between both cavities and lid supported by flanges of stiffening rib formed in ice barrier. Heat-carrier circulation cavity is provided with heat-dissipation members installed in flow direction and fixed to barrier wall.

EFFECT: increased reliability and safety of platform operation in ice circumstances due to increased heat to be transmitted to barrier wall cooperating with ice and as a result increased wall temperature and ice melting rate.
