| Number | Title | Issue Date |
| 7111750 | Liquefied natural gas storage tank Substantially rectangular-shaped tanks are provided for storing liquefied gas, which tanks are especially adapted for use on land or in combination with bottom-supported offshore structure such as gravity-based structures (GBS). A tank according to this invention is... | 09/26/2006 |
| 6966271 | Waveless hull A vessel hull that does not create bow, stern, or transverse waves when moving through the water having an exterior surface that has a substantially constant cross-section along the length of the hull, and an interior surface that substantially encloses a flow chann... | 11/22/2005 |
| 5996520 | Icebreaking method and icebreaker A relatively wide vessel is assisted through an ice field by an icebreaker having a relatively narrow hull. The icebreaker includes two steerable propulsion mechanisms at the opposite ends respectively of the hull, and the propulsion mechanisms are used t... | 12/07/1999 |
| 5567078 | Method for forming a sloped face ice control structure The present invention pertains to sloped-faced, ice control elements that are each spaced apart across a riverbed adjacent to a floodplain region. The elements arrest a breakup ice run. The size and spacing of the ice-resisting elements can vary with rive... | 10/22/1996 |
| 5460110 | Method for changing the characteristics of a ship and a hull form of an icebreaking ship A hull for improved seakeeping characteristics of an icebreaking ship so that the breadth of the ship's hull will be decreased on the aft side of a wide foreship in the vicinity of the waterline. It can be implemented with solid hull form or so that on th... | 10/24/1995 |
| 4831951 | Ice-breaking vessel An ice-breaking vessel having a spoon-shaped bow portion and an obliquely downwardly/rearwardly extending reamer at each longitudinal side is provided with second reamers located above the water line, above the rear portion of the adjacent first reamer an... | 05/23/1989 |
| 4738566 | Ice deflector A semi-submersible oil platform comprising two pontoons (1), columns (2) extending up from the pontoons and supporting a deck structure (3), and stays (4) extending transversally of the pontoons between the columns (2), is provided with a plough-like prot... | 04/19/1988 |
| 4732101 | Stern apron for ice breakers The stern apron is constructed as a volume body tapering to a sharp end in streamlined manner towards the stern of the ship and which at its lower outer edges is in each case wider than in the overlying region, so that the ship's resistance and the necess... | 03/22/1988 |
| 4597350 | Mooring system and liquid cargo transfer facility for ice infested waters A mooring and liquid transfer column which is fixed to the floor of an offshore body of water for securing a marine vessel. The column is resiliently retained and cable supported to permit its being deflected in response to ice forces acting thereagainst.... | 07/01/1986 |
| 4506617 | Ship The prow of the ship with a lower power requirement in open and ice-covered water has a front surface which is forwardly inclined at the top over the entire beam of the ship with marginal cutting edges, preferably on rod-like profiles. The front surface p... | 03/26/1985 |
| 4351255 | Ice-breaking ship In an ice-breaking ship, having sufficient power and being generally designed for efficient ice-breaking, the breaking of the ice is made more effective by changing the zone of ice crushing and shearing which occurs at the stem during normal ice-breaking ... | 09/28/1982 |
| 4102288 | Operations vessel for ice covered seas A mobile monopod operations platform for use in ice covered seas and adapted for carrying out two modes of ice disaggregation, either or both such modes being selectively useable during either transit or relatively stationary operations. An ice breaker bo... | 07/25/1978 |
| 3931780 | Icebreaker vessel An icebreaker vessel having a forecastle of a pontoon-shaped configuration and of a greater width than the width of the ship's hull wherein an upper portion of the lower surface of the forecastle is substantially planar and inclined upwardly, and a lower ... | 01/13/1976 |
| 3930456 | Ship's afterbody, especially for a full-form ship fitted with more than one propeller With ships fitted with more than one propeller, it has been found that a remarkable increase in a ratio speed/power can be obtained especially in full-form ships, if the under-water portion of the ship's afterbody, at a level corresponding to the top clea... | 01/06/1976 |
