20130000537 | PADDLE WHEEL YACHT - A paddle wheel yacht includes a ship body and a ship power device that is arranged on the ship body and consists of a propeller driven by a main engine. The propeller consists of two paddle wheels. The lower edges of the paddle wheels are lower than the bottom surface of the ship body and are symmetrically arranged on the two sides of the ship body. Paddles are uniformly distributed on the outer edges of the paddle wheels in the radial direction and continuously flap the water surface down-backward at high speed when the paddle wheels rotate at high speed. Only the tail part of the ship body contacts with the water surface and the ship body slides on the water surface, so as to avoid large water resistance and obviously improve the propulsion efficiency to realize the high speed and economical navigation of the ship. | 01-03-2013 |

20080295756 | Dual Draft Crane Vessel - Vessel including a hull of a substantially closed surface has at deck level a lifting crane, ballast tanks within the hull and a ballast control unit for admitting water to the ballast tanks for changing the draft of the vessel. The hull has a narrow lower section having first width over a height from keel level to a widening level, and a top section having a larger width than the lower section, extending from the widening level upwards towards deck level. The control unit is adapted to ballast the vessel to have a relatively shallow draft level in a transit mode, so that the wide top section is above water level, while the vessel is traveling, and to ballast the vessel to a relatively deep draft level in a lifting mode so that the widening level is below water level, at least when the vessel is substantially stationary and the crane is in its lifting position. | 12-04-2008 |
20090084297 | SELF-SUSTAINING DATA CENTER OPERATIONAL TO BE EXTREMELY RESISTANT TO CATASTROPHIC EVENTS - The Self-Sustaining Data Center makes use of a site that is inherently immune to catastrophic events and incorporates features to facilitate the substantially continuous availability of data stored therein. The architecture of the Self-Sustaining Data Center makes use of multiple data communication links to sites that are remote from the data center to enable the uninterrupted communication access of customers' computer systems to the mass storage systems operational at the Self-Sustaining Data Center. The Self-Sustaining Data Center also includes facilities that include at least one of: power generation, housing and food for data center staff, and voice communications facilities, thereby to enable the Self-Sustaining Data Center to continue its operation for an extended period of time in the absence of municipal utility services and the possible inability of the data center staff to access outside sources of food and water. | 04-02-2009 |
20090293789 | RIGID TUBE BUOYANCY ASSEMBLY FOR BOATS - A stabilized watercraft having a pointed bow, a transom and curved sides, and a rigid buoyancy tube which extends from the bow to a point past the transom. The tube has a cross-section which is approximately rectangular, but is generally somewhat wider in a lower portion than in an upper portion thereof over at least an aft portion of the boat. The tube has a dead rise in the range of 0° to +15° with the upper surface of the tube being flared outwardly in the range of 30°-80° at the bow portion of the watercraft and an angle of 60°-80° at the stern portion. | 12-03-2009 |
20110271889 | Marine JEEP - The vessel is adapted for the safe navigation in rough and storm sea. A belt of variable waterlines is separated from the body of the boat. Possible target population is transport ships, for example: sea commandos, rescue service, pilot service of seaports, sportsmen, owners of comfortable yachts, the industry of tourism and entertainments. | 11-10-2011 |
20120204775 | FLOAT DEVICE - A float device includes a drive motor provided inside a float hull, a plunger reciprocating along with rotation of the drive motor, an internal oil reservoir for housing an hydraulic oil therein, an externally-opened cylinder attached to the float bull, a buoyant force adjustment piston reciprocating in the cylinder along with exit/entry of the hydraulic oil, and a three-way valve having a first connection port connected to the plunger, a second connection port connected to the internal oil reservoir, and a third connection per connected to the cylinder, for switching the flow between the first connection port and the second connection ports and the flow between the first connection port and the third connection port. | 08-16-2012 |
20120291685 | OFFSHORE BUOYANT DRILLING, PRODUCTION, STORAGE AND OFFLOADING STRUCTURE - An offshore structure having a vertically symmetric hull, an upper vertical wall, an upper inwardly-tapered wall disposed below the upper vertical wall, a lower outwardly-tapered wall disposed below the upper sloped wall, and a lower vertical wall disposed below the lower sloped wall. The upper and lower sloped walls produce significant heave damping in response to heavy wave action. A heavy slurry of hematite and water ballast is added to the lower and outermost portions of the hull to lower the center of gravity below the center of buoyancy. The offshore structure provides one or more movable hawser connections that allow a tanker vessel to moor directly to the offshore structure during offloading rather than mooring to a separate buoy at some distance from the offshore storage structure. The movable hawser connection includes an arcuate rail with a movable trolley that provides a hawser connection point that allows vessel weathervaning. | 11-22-2012 |
20120325136 | Hull design with engine air flow system - A hull design configured for use in combination with at least one outboard motor disposed within a motor compartment formed at the stern of the boat to operatively enclose the outboard motor having an air flow system to direct the flow of air to the engine of the outboard motor during operation thereof and an idle exhaust system to direct the flow of exhaust gases from the motor compartment when the engine of the outboard is at idle while permitting the outboard motor to be trimmed or tilted and rotated for directional control of the boat and a directional fluid flow control to channel or direct water flow to the propeller of the outboard motor during operation thereof. | 12-27-2012 |
