20110005442 | ARCTIC HEAVY-TONNAGE CARRIER AND ICE-RESISTANT PYLON FOR CONNECTING THE SHIP UNDERWATER AND ABOVE-WATER BODIES - The invention applies to shipbuilding dealing with the construction of Arctic heavy-tonnage carriers. The Arctic heavy-tonnage carrier comprises an underwater cargo hull and above-water body in the form of the main deck with a superstructure. The underwater hull is connected to the main deck with an ice-resistant pylon along which the ship load waterline passes and which is located in the fore body of the underwater hull directly behind the forepeak symmetrically related to the center plane of the ship hull. The upper deck of the underwater ship hull has in the area of the pylon a strengthened construction. The pylon structure is a bearing one for the main deck. The underwater hull can be made in the cross-sectional view to the shape of a round-angled rectangle the height of which is 10-12 m and a height-breadth ratio does not exceed 1:6. The underwater hull of said ship has along each side the aft arranged retractable mooring bollard. The ice-resistant pylon for connecting the ship underwater hull to above-water body is executed in the form of a strength longitudinally and transversely framed hull having in the plan view a long and symmetrical shape. The pylon breadth or diameter is significantly less than that of the ship load hull as well as the practical width of channel to be laid by the icebreaker. The pylon height provides the movement of the main deck above the ice surface and underwater hull—beneath the lower ice edge. The invention enables to increase the ship heavy ice-breaking capabilities when going after the icebreaker in the Arctic shelf areas with shallow waters as well as to decrease the ship navigation resistance in broken ice and decrease the height of ship underwater hull. | 01-13-2011 |
20110315060 | ICE BREAKING SYSTEM FOR FLOATING BODY - The invention relates to an ice-breaking system for floating bodies in or near ice, having a protruding stem and at least two trim tanks ( | 12-29-2011 |
20120031318 | VESSEL OR FLOATING STRUCTURE OPERATING IN ICE-COVERED WATERS AND METHOD OF USING IT - The invention relates to a vessel or a floating structure operating in ice-covered waters comprising a hull or the like ( | 02-09-2012 |
20120291684 | Ice Breaking Drilling Vessel With Stowable Mast - A drilling vessel may function both as an ice breaker and, if needed, as a drilling platform for drilling a relief well.

20130087088 | ICEBREAKING VESSEL AND METHOD OF BREAKING ICE - To keep the water around an off-shore installation ( | 04-11-2013 |
20140209004 | Ice Breaking Drilling Vessel With Stowable Mast - A drilling vessel may function both as an ice breaker and, if needed, as a drilling platform for drilling a relief well. The vessel may be provided with a mast that may be stowed when drilling operations are not being conducted. | 07-31-2014 |
20150020723 | WATERCRAFT WITH IMPROVED CHARACTERISTICS FOR TRAVEL IN ICE - The invention relates to a watercraft having improved characteristics for travel in ice, particularly an icebreaker, supply vessel, cargo vessel or corresponding, which watercraft has a hull, which has at the stem portion a propulsion and steering arrangement, which is mainly responsible for movement and steering of the watercraft and which includes at least one skeg-like projection, in which is located at least one propeller device. In accordance with the invention, said skeg-like projections comprise two units located on different sides of the centre line of the hull. Said propeller device is located at the stem end of the skeg-like projection. In addition, the skeg-like projection has between the propeller device and the hull of the watercraft, in the longitudinal direction on the skeg-like projection, one or more thruster devices to provide a water flow mainly transverse in relation to the hull. | 01-22-2015 |

20110239923 | ICEBREAKING VESSEL - A vessel and method for breaking ice drifting in a predominant direction relative to an offshore installation such as a drilling vessel. The vessel is used to deploy an anchor in a position at a distance from the offshore installation and in a direction which, seen from the offshore installation, is substantially in parallel with the direction of movement of the ice. By means of the machinery of the vessel, the direction of the anchor line is adjusted and so is the orientation of the vessel relative to the anchor line to the effect that the propellers can be used to crush and dispose of the ice without using motive energy to hold the vessel against the pressure of the ice. | 10-06-2011 |
