Abstract:
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.
Abstract:
A sealed and thermally-insulating fluid storage tank includes an angle arrangement placed at the intersection between the first and the second walls. The storage tank also includes a first and a second insulating blocks respectively retained on the first and second walls of the supporting structure and forming a corner of the thermally insulating barrier; and a metal angle structure forming a corner of the sealing membrane which is welded onto the plurality of metal plates of the first and second insulating blocks. Each of the first and second insulating blocks is associated with an adjacent insulating panel via a bridging element. Each of the first and second insulating blocks has at least one first and one second stress-relief slots extending respectively parallel and at right angles to the intersection between the first and the second walls.

Abstract:
The invention relates to a method for treating and feeding natural gas from a tank for storing liquefied gas storage to an apparatus for generating power, and to a burner of an apparatus for generating power in a ship, said method comprising the following consecutive steps: supplying power to the apparatus for generating power, during which step natural gas is fed through a phase separator that returns a heavy fraction of the natural gas containing the hydrocarbons having the longest carbon chains to the tank as condensate and feeding a light fraction of the natural gas containing the hydrocarbons having the shortest carbon chains to the apparatus for generating power; and then recovering the heavy fraction of the natural gas, during which step natural gas is carried from the tank to the burner, bypassing said phase separator.
Abstract:
A motorized support device for a handling system intended to handle at least one flexible pipe for transferring fluid; the support device comprises:a frame,a support borne by the frame, the support having an upper support surface for supporting the flexible pipe on the frame,and a drive member borne by the frame and able to drive the flexible pipe in two-way translation in a predetermined longitudinal direction.
Abstract:
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.
Abstract:
A bending device for forming a corrugation in a metal sheet, the bending device having a frame, a die having two die elements, each having a concave half-impression, mounted able to slide on the frame; a punch having a head able to engage inside the impression of the die so as to press the metal sheet; and two side clamps mounted sliding and able to move vertically with respect to the lower frame so as to clamp the metal sheet against the bearing surfaces of the die elements. During the displacement of the punch into its bending position, the metal sheet transmits a traction force to the die elements and to the side clamps so as to displace them into their near position.
Abstract:
An impermeable and thermally insulated tank built into a load-bearing structure, the tank wall comprising: a thermally insulated barrier attached to a load-bearing wall and made of insulated blocks, juxtaposed in parallel rows separated from one another by gaps, an impermeable barrier supported by the thermally insulated barrier and made of welded metal sheets. Each insulated block carries, on the face of same opposite the load-bearing wall, two metal connecting strips arranged in parallel to the sides of the insulated block. The sheets of the membrane carried by the insulated block are welded to the strips. The connecting strips are rigidly connected to the insulated block carrying same. The sheets each have at least two orthogonal folds parallel to the sides of the insulated blocks, the folds being inserted into the gaps formed between two insulated blocks.
