A precast, prestressed concrete tank and method that facilitates construction of a primary inner tank within a secondary outer tank, and which permits for the construction of the primary inner tank after the secondary outer tank has been erected, but without requiring insertion through a top of the secondary outer tank, or by tunneling underneath the secondary outer tank, is disclosed. The primary inner tank has an inner wall and the secondary outer tank has an outer wall (precast, prestressed concrete) and wire windings. The primary inner tank is disposed inside of the secondary outer tank. The secondary outer tank has a plurality of first precast outer wall panels, and a temporary construction opening frame. The temporary construction opening frame defines an access doorway during construction of the tank. The temporary construction opening frame is disposed on a foundation base slab.

A method for regasification of liquefied natural gas (LNG) and an LNG regasification terminal employing said method. An LNG carrier is filled with LNG at an LNG hub and transports the LNG to a receiving terminal. The LNG is offloaded to LNG storage at the receiving terminal. The LNG storage has less storage capacity than the storage capacity of the carrier. The LNG is regasified at a regasification rate at the receiving terminal. The carrier is maintained at the receiving terminal until the carrier is empty, and then returns to the LNG hub to be filled with more LNG. The process is then repeated. The storage capacity of the LNG storage is sufficient to supply LNG for regasifying the LNG at the regasification rate until the carrier returns with additional LNG from the LNG hub. The carrier is the sole source of LNG for the receiving terminal.

A pressurized gaseous and liquified hydrocarbon feedstock storage system method. The system includes a plurality of underground circuits or sections having parallel pipes joined together by radial ends arranged in various configurations to minimize plot space and maximize the amount of pressurized gaseous fuel stored.

A membrane finishing sheet, which is disposed at a membrane finishing part among multiple membrane sheets which form a sealing wall installed at a membrane type cargo, comprises a corrugated part having a structure closed in a direction toward the membrane finishing part. In addition, a membrane insulation structure comprising a membrane finishing sheet according to the present invention comprises a membrane finishing sheet disposed at a membrane finishing part among multiple membrane sheets which form a sealing wall installed at a membrane type cargo. Among four sides of the membrane finishing sheet, a finishing side in contact with the membrane finishing part has a structure in which the corrugated part is closed and thus provides a membrane insulation structure that does not require a separate finishing member for sealing a membrane.

Disclosed are a corrugated plate having a smooth top surface and drawbeads, and a storage container. The corrugated plate includes a corrugated plate body, a longitudinal corrugation, a transverse corrugation, and an intersection portion. The intersection portion includes a smooth top surface and four drawbeads extending from the top surface to the corrugated plate body. The top surface transitions to the drawbeads smoothly. An overall extension direction of each of the drawbeads intersects a transverse direction, a longitudinal direction, and a height direction perpendicular to the corrugated plate body.

The invention relates to an insulated chamber comprising at least one element that may operate at sub-ambient temperature, the space around the element(s) being filled with solid insulation and means for injecting a gas containing at least 95 mol-% nitrogen into the insulation, at least some of the gas-injection means opening at a position vertically above at least one element to insulate.

The invention relates to a sealed and thermally insulating tank for storing a fluid, wherein a tank wall comprises, successively in a thickness direction, a secondary thermal insulation barrier (1), a secondary sealing membrane (4), a primary thermal insulation barrier (5) and a primary sealing membrane (7), wherein the secondary sealing membrane (4) is a corrugated metal membrane comprising a series of parallel corrugations (25, 26) forming channels and flat portions located between said corrugations (25, 26), and wherein anti-convection filler elements (16, 20, 22) are disposed in the corrugations (25, 26) of the secondary sealing membrane (4) to generate a head loss in said channels.

The invention relates to a method for providing pressurized gas from a source of liquefied gas to a consumer (8), wherein vaporized gas is supplied from the source of liquefied gas (1) through a main input line (2) to a compressor arrangement (300) for pressurizing the vaporized gas, the compressor arrangement (300) comprising a plurality of compressor modules (3, 5, 31, 51), each compressor module being able to operate independently from any other compressor module of the compressor arrangement (300), one or more of the compressor modules (5, 51) of the compressor arrangement (300) can be bypassed, and wherein gas is conducted through only a part or all of the compressor modules depending on at least one of pressure level, temperature level, mass flow and composition of the gas to be provided to the consumer (8).

Corrugated fluid-tight membrane fluid-tight wall (1) including two series of parallel corrugations forming a plurality of nodes (5) at the crossings of said series of corrugations, wave reinforcements (11) being arranged under the corrugations (3) of the first series of corrugations (3), two successive wave reinforcements (11) in a corrugation (3) each including a hollow sole (15) and a reinforcement portion (16) disposed above the sole (15), the two wave reinforcements (11) being developed in the corrugation (3) on either side of a node (5), a connecting member (13) at the level of the node (5) being nested in the soles (15) of said two wave reinforcements (11) in such a manner as to assemble the two wave reinforcements (11) in an aligned position.
