FIELD: transport.
SUBSTANCE: invention relates to offshore oil production platform 1 equipped with turret 1a jointed to its bottom. Note here that platform hull has lengthwise boards extending in (X-X) direction. Proposed platform differs from known designs in that said lengthwise boards (1b) are furnished with multiple devices 10 for local breaking of floating ice, each comprising breaking tool 11 with, at least, one sharpened part 11a to break ice by repeated action in tool translation or rotation relative to lengthwise board. Note here that said sharpened part comes in local contact with floating ice on moving top-down with force equal, preferably, to, at least, 10000 kN. Note also that said breaking tool is driven by guide structure 14 in translation and/or guide structure 13 in rotation. Said structures are mounted on lengthwise board.
EFFECT: perfected design.
