ARCTIC ICE-BREAKER FREIGHT SUPERSHIP WITH ICREPROOF PYLON Russian patent published in 2010 - IPC B63G8/04 B63B1/12 B63B35/08 

FIELD: transport.

SUBSTANCE: invention relates to shipbuilding and production of marine super ships to be operated in Arctic ice fields with ice breaker escort. Proposed supership has submerged freight hull, above-water section representing floating main deck with superstructure, assembly to joint submerged hull and above-water section, and ice breaking device. Said jointin assembly represents iceproof pylon with loadline running along said pylon. Pylon is arranged at submerged hull bow section, directly behind forepeak in symmetry with ship hull diametric plane. Submerged hull top deck has reinforced structure arranged in the pylon area. Pylon structure makes bearing structure for main deck, while its front part represents ice breaking device. Said ice breaking device notably extends towards the bow from submerged hull. Pylon width is notably smaller than that of submerged hull. Pylon represents high-strength hull with crosswise and lengthwise frame sets in the form of elongated trapezoid with smaller base at stern. Trapezoid smaller base is at top in cross section. Pylon transom bulkhead is inclined towards bow. Note here that pylon height allows ship main deck to float above ice and submerged hull to flow below ice.

EFFECT: higher efficiency and capability of ice breaking.
