  • Publication number: 20110209771
    Abstract: The present invention discloses apparatuses, systems, and methods for controlling liquid impact pressure in liquid impact systems. The liquid impact systems include at least one gas and a liquid, the gas having a density (PG) and a polytropic index (?) and the liquid having a density (PL). The methods include the step of calculating a liquid impact load of the liquid on the object by determining a parameter ? for the system, wherein ? is defined as (PG/PL) (??1)/?. The systems are also configured to utilize the parameter ?. The parameter ? may be adjusted to increase or reduce the liquid impact load on the system. Automatic, computer-implemented systems and methods may be used or implemented. These methods and systems may be useful in applications such as LNG shipping and loading/off-loading, fuel tank operation, manufacturing processes, vehicles dynamics, and combustion processes, among others.

  • Publication number: 20100108145
    Abstract: A method and system for transporting fluid is described. The method includes coupling a transit vessel to a terminal vessel associated with at least one terminal. The transit vessel and the terminal vessel are coupled at an open sea or lightering location, which may be selected based upon operational conditions. Then, cryogenic fluid is transferred between the transit vessel and the terminal vessel, while the transit vessel and terminal vessel are moving in substantially the same direction. Once the transfer is complete, the terminal vessel decouples from the transit vessel and moves a terminal to provide the cryogenic fluid to the terminal. The cryogenic fluid may include liquefied natural gas (LNG) and/or liquefied carbon dioxide (CO2).

  • Publication number: 20100074692
    Abstract: Methods and systems for receiving liquefied natural gas (LNG) and delivering vaporized natural gas to a pipeline in fluid communication with onshore equipment and methods for importing LNG. In one embodiment, an open-sea berth import terminal includes a platform, which is fixed to the sea floor and includes two or more sets of berthing structures. LNG carriers berth at the open-sea berth import terminal to transfer LNG to a storage vessel moored at one of the berthing structures. LNG vaporization facilities, either on the storage vessel or the platform, vaporize the LNG prior to delivery to the pipeline. The storage vessel may include a barge or another LNG carrier. In other embodiments, the open-sea berth import terminal may have no storage facilities, but two LNG carriers may berth at the berthing structures to concurrently perform offloading operations, with one transferring LNG and the other performing other offloading operations to enhance operations.

  • Patent number: 7540200
    Abstract: This invention relates generally to testing apparatus and methodology for measuring fluid dynamic properties of structures within fluid flows. One embodiment includes a fluid induced motion testing apparatus of the type which includes a test rig suitable for holding a test body in a fluid body. The apparatus may include any of an actuator suitable for producing a force upon the test body; a turbulence generator located in the fluid body up current from the test body suitable for generating a turbulent flow field with uniform turbulence intensity across the fluid body-test body interface, the turbulent flow field including dominate vortical structures, the axis of the vortical structures about parallel to the longitudinal axis of the test body; or a test body adjuster suitable for adjusting the test body relative to the fluid current in four or more increments, thereby enabling multiple headings of the test body to be tested against the current of the fluid body.

  • Patent number: 7469651
    Abstract: A tank is provided that reduces sloshing pressures in the corner sections of a tank, such as an LNG membrane tank. The tank includes a sloshing impact reduction system placed in selected corner sections within the tank. The system serves as a slosh attenuation system, and reduces the severity of the corner geometry and improves the flow of fluids into the tank corner. In one embodiment, an impermeable structure is disposed in an internal corner section of the tank. The impermeable structure may be a triangular planar surface, or a non-planar structural surface. The non-planar structural surface may be a concave surface or other curved surface. In another arrangement, a permeable structure is placed in an internal corner section of the tank. Such a permeable structure would enable fluid to pass through the device, but would reduce the fluid velocities and accelerations via friction or eddies. The permeable structure may be either rigid or flexible.
