Abstract: 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.

Abstract: A sealed and thermally insulating tank has a thermally insulating barrier and a sealing membrane. The tank has a channel extending in a longitudinal direction along the sealing membrane. The thermally insulating barrier forms a bottom of the channel. The tank further has a closure member that is a flexible film. The flexible film has a first fastening zone extending transversely to the longitudinal direction of the channel and fastened to the bottom of the channel and a second fastening zone extending transversely to the longitudinal direction of the channel and fastened to the sealing membrane. The flexible film has a closure portion interposed between the first fastening zone and the second fastening zone. The closure portion closes the channel in order to create a loss of pressure in the channel.

Abstract: A method for assisting the management of a vessel comprising at least one tank configured to contain liquefied gas and a vapor phase treatment system capable of sending boil-off gas exiting the tank to a propulsion engine of the vessel or to a gas combustion unit on board the vessel and capable of extracting a portion of the liquid phase contained in the tank and of evaporating this portion in order to send it to the propulsion engine. The method comprises: generating at least one tank management scenario defining an evolution of the pressure of the gas phase contained in the tank along a path of the vessel; computing a cost function that at least depends on a total amount of boil-off gas generated in the tank along the path; and displaying to a user the tank management scenario as a function of the computed cost function.
