Disclosed is an apparatus for controlling a pressure vessel including a clamp that surrounds an outer peripheral surface of the pressure vessel fixed to a subject target, a driver that provides a driving force for adjusting a fastening force of the clamp according to an internal pressure of the pressure vessel, and a controller that performs a control such that rotation of the driver is prevented during an abnormal operation of the driver.

An apparatus for energy replenishment, fueling for non-hydrocarbon fueled vehicles includes a reconfigurable display comprising a matrix graphically representing and communicating locations and energy type or refueling status of a plurality of energy dispensers for non-hydrocarbon fueled vehicles. A method of scheduling availability of a plurality of energy dispensers in a refueling station forecourt for non-hydrocarbon fueled vehicles includes providing the reconfigurable display to help vehicle operators choose a location that improves traffic flow and reduce congestion within the forecourt. The reconfigurable display may indicate that a first energy dispenser in the plurality of energy dispensers is unavailable until a second energy dispenser in the plurality of energy dispensers immediately forward of the first energy dispenser is occupied.

A sealed and insulating reservoir contains a pressurized cold fluid in a rigid, sealed enclosure. A fluidtight membrane is positioned to contact the cold fluid contained in the reservoir. An insulating barrier is placed between the fluidtight membrane and the internal surface of the rigid enclosure, with the insulating barrier forming a support surface to support the fluidtight membrane. A pressure balancing device is able to limit the pressure difference between a first sealed volume located inside the fluidtight membrane, and a second sealed volume located outside the fluidtight membrane. The pressure balancing device typically includes a fluid circuit having two chambers sealingly separated by a movable separator. The first chamber is linked to the first sealed volume, and the second chamber is linked to the second sealed volume. The movable separator exerts a loading force in the direction of the second chamber.

The invention relates to a calculation method (400) for calculating dimensions of spacer elements (40) intended for the construction of a liquid-product storage facility (1), the storage facility comprising a load-bearing structure (10) having an internal space (11) delimited by a load-bearing wall (12) and a sealed tank (20) installed in the internal space (11) of the load-bearing wall (12).

The calculation method (400) is based on an iterative decrease in the dimensions of the spacer elements (40) under the constraint of acceptability criteria, the acceptability criteria comprising planarity criteria limiting deformations of planar facets (224) of the tank (20).

A gas pressure tank system is disclosed, and includes at least one gas pressure tank comprising a thermal pressure relief device. The thermal pressure relief device may include a valve unit fluidically connected to the at least one gas pressure tank and including at least one fluid path, by way of which a gas stored in the at least one gas pressure tank can be discharged into an environment. The valve unit may include a locking element which can be moved between an open position, in which the gas can flow through the fluid path, and a closed position, in which no gas can flow through the fluid path. The thermal pressure relief device may include a first trigger means configured to detect heat impact at least at one location of the gas pressure tank system spatially separated from the installation location of the thermal pressure relief device.

A liquefied gas storage facility has a sealed and thermally-insulating tank. A bottom wall of the tank includes a plurality of angular sectors which are images of each other through rotation by a predetermined angle about a vertical axis, the predetermined angle being equal to k.360/N, where k is a positive integer. A vertical wall of the tank has a vertical row of planar insulating wall modules disposed on each vertical load-bearing section of a load-bearing structure of the tank. An azimuthal angular deviation with respect to said vertical axis between two rows of planar insulating wall modules disposed on two adjacent vertical load-bearing sections is equal to 360/N, preferably with an accuracy better than 5 mm.
