The invention relates to a tracing method (2000) for constructing a liquefied gas storage facility (1). The facility (1) comprises a sealed and thermally-insulating tank (20). A bottom wall (21) of the tank (20) includes a plurality of angular sectors (25) 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 (22) of the tank (20) comprises a vertical row (120) of planar insulating wall modules (131, 131A) disposed on each vertical load-bearing section (14) of a load-bearing structure of the tank. The tracing method ensures that an azimuthal angular deviation with respect to said vertical axis between two rows (120) of planar insulating wall modules (131, 131A, 171) disposed on two adjacent vertical load-bearing sections (14) is equal to 360?/N, preferably with an accuracy better than 5 mm.

A gas supply system includes a first tank, a first path into which a first gas generated by vaporization of a first low-temperature liquefied gas flows, a gas boosting mechanism being disposed in the first path, a second path that is a path configured to extract the first low-temperature liquefied gas from the first tank, a pump and a vaporization mechanism being disposed in the second path and a reliquefaction path that is a path configured to liquefy at least part of the first gas extracted from an upstream side of the gas boosting mechanism in the first path and to cause the liquefied first gas to flow into an upstream side of the pump in the second path, a cooling heat exchanger configured to cool the first gas by a second low-temperature liquefied gas or a second gas being disposed in the reliquefaction path.

A low temperature liquid tank includes: a storage tank having a bottom portion obtained by joining a plurality of bottom plates; and a support portion supporting the bottom portion. The support portion includes: an outer support portion supporting a margin of the storage tank; and an inner support portion disposed inside the outer support portion and having a heat insulation in which creep occurs when a load is applied. An initial height of an upper surface of the inner support portion is set so that, during a service life of the low temperature liquid tank, maximum bending stress applied to the bottom plates due to a difference between a height of the upper surface of the inner support portion and a height of an upper surface of the outer support portion remains equal to or smaller than an allowable bending stress of the bottom plates.

A cryogenic vaporization system and a method for controlling the system are provided. The system includes a first vaporizer arrangement and a second vaporizer arrangement configured for receiving a liquid cryogen and outputting a superheated vapor. The second vaporizer arrangement is connected in parallel with the first vaporizer arrangement, and includes one or more banks of ambient air vaporizer (AAV) units or loose fill media with a high heat capacity. The second vaporizer arrangement has a different configuration than that of the first vaporizer arrangement. The system further includes at least one control valve controlling provision of the liquid cryogen to at least one of the first vaporizer arrangement and the second vaporizer arrangement.

A sampling device having at least two inputs each configured to receive samples from a corresponding feedstock input line and a sample accumulator. The device also includes a mass flow controller associated with each feedstock input line, each mass flow controller having a sample output and being configured to receive a signal representative of the flow rate at each input, where each mass flow controller adjusts the flow rate of its respective sample from its respective sample output in response to receiving representative signals. Further the device includes at least a first and second sample output line respectively connected with a sample output of each mass flow controller, each sample output line being connected to an input of the sample accumulator for introduction to the sample accumulator of samples from the output of the mass flow controllers.

A Sealed and thermally insulated tank has a tank wall on a carrier structure. The tank wall has an insulating barrier, sealed barrier and an anchoring member. The sealed barrier has a first undulating metal membrane and a second undulating metal membrane which are located at one side and the other of the anchoring member, along an assembly edge which is oriented parallel with a longitudinal direction of the anchoring member. The first and the second membrane undulate with a first series of undulations which intersect with the assembly edge Terminal undulation portions which are associated with the first series of undulations of the first membrane extend in a direction transverse to the assembly edge in the direction of the second membrane, beyond the terminal undulation portions which are associated with the first series of undulations of the second membrane.

A securing device for securing a pipe in a housing, which has a cylindrical collar, at least three securing arms, each securing arm containing a proximal arm portion mounted on the cylindrical collar, a distal arm portion bearing a bearing pad, the bearing pad containing a bearing surface facing away from the collar and intended to collaborate with a wall of the housing in which at least one of the securing arms contains a guideway capable of translationally guiding the distal arm portion with respect to the proximal arm portion, an elastic member being coupled to the guideway so as to be able to apply a return force that pushes the distal arm portion away from the proximal arm portion.

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.
