Abstract: An installation for storing and transporting a cryogenic fluid on a ship includes: a sealed and thermally insulating tank, having a ceiling wall including, from the outside to the inside, a primary thermally insulating barrier and a primary sealing membrane intended to be in contact with the cryogenic fluid; and a sealed line penetrating through the ceiling wall of the tank, the line including a bottom portion of which a first end is situated inside the ceiling wall of the tank and a second end is situated outside the ceiling wall of the tank in a thicknesswise direction of the ceiling wall, and a top portion fixed to the second end of the bottom portion. The bottom portion includes an alloy with low thermal expansion coefficient. The primary sealing membrane is tightly fixed to the bottom portion of the line around the line.

Abstract: A sealed and thermally insulating tank incorporated in a supporting structure (2), the tank including at least one inclined tank wall (1) forming an angle with a horizontal direction and fixed to a supporting wall of the supporting structure (2) is disclosed. The tank wall (1) has a multilayer structure including successively, in the direction of thickness from the outside to the inside of the tank, a thermally insulating barrier (3) held against the corresponding supporting wall and a sealed membrane (4) carried by the thermally insulating barrier (3). The tank includes sealed strips (15) in the space formed between the thermally insulating barrier (3) and the supporting wall.

Abstract: A method for checking the sealing of a sealed tank for storing a liquefied gas at low temperature, the tank having an inner hull and a secondary sealing membrane, a secondary space that is arranged between the inner hull and the secondary sealing membrane, a primary sealing membrane and a primary space that is arranged between the primary sealing membrane and the secondary sealing membrane is disclosed. The method has the following main steps: generating a pressure lower than the pressure of the primary space in the secondary space using a suction device, measuring the temperature of an outer surface of the inner hull, and detecting the location of a sealing defect of the secondary sealing membrane in the form of a cold spot on the outer surface of the inner hull.

Abstract: The invention relates to a method for managing maintenance for a ship comprising a sealed and thermally insulating tank for transporting liquefied gas. The method comprises the steps consisting in determining 310 a current filling level of the tank, determining 320 a current state of movement of the ship, determining 330 a current sloshing index IBi from the current filling level of the tank and the current state of movement of the ship, taking into account the position and the geometry of the tank, integrating 340 the determined current sloshing index IBi into a wear index IUi that takes into account a history of the sloshing indices. The wear index is then compared to a threshold in order to indicate if the tank needs to be inspected, depending on the result of the comparison.

Abstract: The invention relates to a tank wall (1) fixed onto a supporting wall (3) wherein the secondary insulating barrier comprises a plurality of secondary rows (A, B, C) parallel to a first direction and juxtaposed in a second direction at right angles to the first direction according to a repeated pattern. The secondary sealed membrane comprises a plurality of strakes (21) parallel to the first direction, the size of the repeated pattern of the secondary rows (A, B, C) being an integer multiple of the size of a strake (21) in the second direction. The primary insulating barrier (5) comprises a plurality of primary rows parallel to the first direction, and the primary sealed membrane has first corrugations (56) parallel to the first direction and spaced apart by a first regular spacing (58), wherein the size of the repeated pattern of the primary rows is an integer multiple of said first regular spacing (58).

Abstract: A tank includes a secondary insulation barrier, a secondary sealing membrane resting on the secondary insulation barrier, a primary insulation barrier resting on the secondary sealing membrane, a primary sealing membrane resting on the primary insulation barrier, and a primary reinforcing member. The primary sealing membrane includes primary corrugations and the secondary sealing membrane includes secondary corrugations projecting toward the interior of the tank. The primary and secondary corrugations are superimposed along a thickness direction. The primary insulation barrier has passages, and the secondary corrugations are accommodated in the passages. A dimension of the primary insulation barrier is less than a dimension of the secondary corrugations along the thickness direction, so the secondary corrugations extend through the passages and are partially accommodated in the primary corrugations. The primary reinforcing member is interposed along the thickness direction between superimposed primary and secondary corrugations so as to reinforce the primary corrugation.
