The present disclosure discloses a high-pressure gas storage and supply device. The disclosed high-pressure gas storage and supply device includes a plurality of gas storage tanks that store a high-pressure gas therein and selectively discharge the stored gas, and a gas transport pipe including tank inlet/outlet lines respectively connected to the plurality of gas storage tanks to fill the gas in the gas storage tanks or discharge the gas stored in the gas storage tanks. Thus, in the present disclosure, the gas may be filled in or discharged from the gas storage tanks by the same one tank inlet/outlet line, and thus a structure for filling or discharging the high-pressure gas can be simplified.

A tank state estimating method of estimating a state in a tank at a predetermined point in time on a sailing course of an LNG carrier is provided. The LNG carrier carrying LNG stored in the tank as a cargo. The tank state estimating method includes: a first step of acquiring information related to specification of the tank; a second step of acquiring information related to a state in the tank at a start point of a target section on the course; a third step of acquiring information on a predictive value of liquid fluctuation of the LNG in the tank during the section, the predictive value being obtained on a basis of a weather forecasting value during the section and information on the weather forecasting value; and a fourth step of calculating the state in the tank at an end point of the section by thermal transfer calculation based on thermodynamics on a basis of the information acquired in the first to third steps in assuming that a heat input to the tank during the section is used for vaporization of the LNG in the tank.

A device for transferring a fluid from a supply tank to a receiver tank includes at least one duct for charging the receiver tank with liquid and at least one duct for return of the gas. The gas return duct is configured to transfer the gas contained in the receiver tank at a pressure close to or significantly different from the pressure of the supply tank.

A tank is used in the containment, transport, and/or storage of fluids, e.g., one or more liquids and/or gases. In one embodiment, the tank includes a plurality of segments collectively defining an interior chamber that retains the fluid(s), each of which includes opposing ends defining beveled mating surfaces. The tank also includes a plurality of endcaps positioned between, and in engagement with, adjacent segments, as well as a plurality of webs that include a series of first webs having a first configuration and a series of second webs having a second, different configuration. The first webs are positioned within the plurality of segments between the ends thereof, and the second webs are positioned within the endcaps. In an alternate embodiment, the tank is devoid of the endcaps, and instead, includes segments defining beveled mating surfaces that intersect at junctures to define four corner sections of the tank.

The present invention relates to a computer-implemented method and system for computing a transition parameter of a liquefied gas storage medium, the storage medium having at least one sealed and unrefrigerated tank, the transition parameter characterizing an evolution of a two-phase mixture contained in the sealed and unrefrigerated tank between an initial state and a final state, the two-phase mixture including a liquid phase and a vapour phase, the transition parameter may be a duration of the transition, a liquid bleeding rate or a vapour bleeding rate.

One or more indicators provide an indication of fueling status of a hydrogen powered vehicle. One or more sensors detect temperature and/or other characteristics of the fuel provided to the vehicle and provide an electrical signal to one or more of the indicators to permit an indication of fueling status. The indicators, which may be visual and/or audible, may be positioned on the fueling apparatus and on the vehicle in the vicinity of a fueling receptacle. The indicators may also be positioned elsewhere on the vehicle and may be separate from the vehicle such as on or around a fueling station and/or on separate computerized devices.
