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.

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.

The present invention relates to a remote propane-monitoring device primarily comprised of a body with a front surface further comprised of a display and at least one button, a retaining clip and a mobile application. In the preferred embodiment, the body is generally rectangular and is made from a rigid, water-resistant/water-proof, weather-resistant plastic. The body further has a clip assembly that allows the device to attach to a propane gauge of a propane tank and a piping/tubing that attaches to the tank. The device is further comprised of an internal pressure gauge that reads the pressure of the propane gas being pushed out from the tank to determine the level of propane gas left in the tank and relay said information to the mobile application.

A hydrogen filling system includes a first tank and a second tank that are configured to be filled with hydrogen and communicate with each other, a first hydrogen feeder and a second hydrogen feeder configured to feed hydrogen to the first tank and the second tank, and a controller configured to control the first hydrogen feeder and the second hydrogen feeder. The controller estimates a hydrogen fill factor of the first tank and the second tank, based on a first internal temperature of the first tank and a second internal temperature of the second tank, and a first pressure of hydrogen gas fed from the first hydrogen feeder and a second pressure of hydrogen gas fed from the second hydrogen feeder. The controller is configured to stop the first hydrogen feeder and the second hydrogen feeder when the hydrogen fill factor reaches a predetermined threshold fill factor.

A type IV conformable pressure vessel is provided comprising an elongated folded tank and a valve assembly configured to pass fluid into and out of an interior of the tank through first and second filling couplers directly connected to a respective first and second end of the tank. The tank has at least two chambers for the storage of fluid. The valve assembly receives fluid from an external source, selectively provides the external fluid through a Venturi nozzle into a mixing chamber, recirculates fluid from the second end of the tank into the mixing chamber, and delivers the mixture of the recirculated fluid and the external fluid to the first end of the tank.

A metering device for attaching to a container configured to store a fluid, the device including: a valve configured to control the amount of fluid dispensed from the container; a user interface comprising at least one control configured to operate the valve between an open position and a closed position; and a control circuit configured to set a threshold amount of the fluid to be dispensed from the container, where the control circuit is configured to override the user interface and close the valve when the threshold amount of fluid to be dispensed has been reached.
