FIELD: water-development works for production of oil and gas on shelves of freezing sea. SUBSTANCE: platform includes bearing head-piece, working platform and piles secured in ground; piles pass through head-piece. Head-piece consists of bearing holder provided with jigs for securing the piles; these jigs are supported by holder of body made in form of hyperboloid of revolution on whose upper band working platform is mounted. Piles are made form steel pipes; outer surfaces of piles and inner surfaces of jigs has form of auger. During interaction with moving ice field, platform is exposed to minimum horizontal loads due to specific shape of body. EFFECT: enhanced efficiency of ice breaking due to reduced energy of waves and consequently vibration of structure. 1 dwg
