FIELD: transport.SUBSTANCE: invention relates to ship building, particularly, to arctic navigation. In arctic navigation ice-breaking sip and common ship, common ship is, first, arranged in ice-breaking ship dock. Then, all ice-breaking ships along with icebreaker are coupled in butting column by fitting ship fore to aft recess of forward ship and with the help of unified docking unit. Note here that clearance between aft of every ship and fore of coupled ship is overlapped board skegs that rule out crushed ice effects at ship fore lines. Icebreaker aft has intake part of unified docking assembly and, optionally, devices of stiff docking with fore of the next ship.EFFECT: higher efficiency and safety.34 cl, 11 dwg, 1 tbl |
