FIELD: cryogenics.
SUBSTANCE: invention relates to cryogenic equipment. Sealed and thermally insulated tank arranged in a bearing structure (1) and its walls are attached to the walls of said bearing structure. Tank wall having in succession, in the thickness direction from the inside toward the outside of said tank, a primary sealed barrier (3), primary thermally insulating barrier (4), secondary sealed barrier (5) and secondary thermally insulating barrier (6). Tank further comprising a through element (7, 910) arranged through the tank wall. Tank wall around the through element comprises: secondary insulating blocks arranged on the wall of the bearing structure around the through-element and forming the secondary thermally insulating barrier around the through element so that the through-element passes through the secondary thermally insulating barrier between said secondary insulating blocks, secondary insulating blocks being covered by a first sealed layer forming the secondary sealed barrier. Plate (722, 923) arranged parallel to the tank wall having a surface facing toward the inside of the tank at the same level as the first sealed layer (17, 932) forming the secondary sealed barrier. Plate being connected in a sealed manner directly or indirectly to a peripheral wall of the through element all around the through-element. Second sealed layer (723, 936, 823, 1036) fixed in a sealed manner straddling the first sealed layer and the plate all around the plate. Tank wall further comprises primary insulating elements arranged on the secondary sealed barrier around the through element and forming the primary thermally insulating barrier around the through element. Through element passes through the primary thermally insulating barrier between the primary insulating elements, the primary insulating elements being covered by primary sealed barrier elements, which are connected in a sealed manner to the peripheral wall of the through element so that the through element passes through the primary sealed barrier between the primary sealed barrier elements. Plate (722, 923) is a circular plate having a circular exterior shape. Second sealed layer comprises a circular window having a diameter smaller than the outside diameter of the circular plate, the secondary sealed barrier being passed through by the through element through the window of the second sealed layer. Ship for conveying a cold liquid has a double hull and a sealed and thermally insulated tank disposed in the double shell. Ship is used for loading and unloading a cold liquid product. Cold liquid product is fed through thermally insulated pipes from the offshore or onshore storage to the ship’s tank or from the said tank to the said storage. Transfer system for a cold liquid product, the system comprising a ship, insulated pipelines arranged in such a way as to connect the tank installed in the hull of the ship, to an off shore or on-shore storage facility and a pump for driving a stream of cold liquid product through the insulated pipelines from to the off shore or on-shore storage facility to or from the tank of the ship.
EFFECT: sealed and thermally insulated tank for liquid media was offered.
