SEALED AND HEAT-INSULATING FLUID STORAGE TANK, FLUID CARRIER, FLUID TRANSFER SYSTEM AND METHOD OF LOADING OR UNLOADING VESSEL Russian patent published in 2024 - IPC B63B25/16 F17C3/02 F17C6/00 F17C9/00 F17C13/08 

FIELD: packing and storage.

SUBSTANCE: group of inventions relates to a sealed and heat-insulating reservoir for storing a fluid, a vessel for transporting a fluid, a fluid transfer system and a method for loading or unloading a vessel. Sealed and heat-insulating reservoir for storage of fluid medium contains bearing wall, anchor devices and reservoir wall. Wall of the reservoir includes a heat-insulating barrier and a membrane successively in the direction of thickness from the outer side to the inner side of the reservoir. Heat-insulating barrier comprises insulating blocks of parallelepiped shape located adjacent to each other on bearing wall. Each of the insulating units includes a cover plate forming a support surface for the sealing membrane. At least one of the anchor devices comprises a clamping unit including a lower plate and an upper plate, a connecting element connecting the lower plate to the upper plate, and a separating element located between the lower plate and the upper plate. Separating element includes a thrust part defining the minimum distance between the lower plate and the upper plate, an anchor rod protruding from the clamping unit. Anchor rod includes a lower end attached to the bearing wall between adjacent insulation blocks, and an upper end connected to the lower plate, and a separating part located under the lower plate. Separating part includes an upper surface configured to rest on a lower plate of the clamping unit, and a lower surface, plurality of adjacent insulating blocks of the anchor rod includes a lower plate located in parallel and at a distance from the cover plate, and a unit of fiber-reinforced foamed polymer material located between the cover plate and the bottom plate. Cover plate and block of foamed polymer material include a recess opening angular section of lower plate. Lower surface of the separating part rests on the angular sections of the plurality of insulating blocks. Lower plate of the clamping unit interacts with angular sections of a plurality of insulating blocks through a separating part.

EFFECT: providing flexibility of anchor devices in the direction of compressive force exerted from the inner area of the reservoir, for averaging the reaction of the heat-insulating barrier to compression stresses.
