Systems and methods for insulating vessels are disclosed. In one or more embodiments, the disclosure provides a vessel insulation system (e.g., for use with a reactor or pressure vessel), which includes a floating ring sized to circumscribe a top nozzle of a vessel; a plurality of straps connected to the floating ring, the plurality of straps extending downward from the floating ring and being positioned to run along a length of the outer shell of the vessel; and a plurality of segmented rings positioned to circumscribe the outer shell of the vessel and connected to the plurality of straps. The plurality of segmented rings is configured to support an insulation material circumscribing the outer shell of the vessel, which can provide effective securement of the insulation material around the outer shell without welding components on the vessel to secure the insulation material.

The present invention utilize a combination of wooden elements (20, 21), stainless steel membranes (22) and insulating materials in embodiments of the present invention. An object of the present invention is to be able to build the LNG tank separately from the building of the ship, and fit a complete or nearly complete LNG tank into the space of the ship hull when appropriate during the process of building the ship. Therefore, the building of the tank and the ship can be done in parallel, which by experience reduces the total time of building the ship considerably, and hence provide substantial cost savings.

The present invention relates to the use of a layer of a material as a thermal insulation barrier on an interior surface of wall of a containment system for a fluid, wherein the cryogenic fluid is one of liquid natural gas (LNG), liquefied nitrogen, liquefied propane, liquefied oxygen, liquefied carbon dioxide and liquefied hydrogen, the material having a contact angle which is at least 150.

An internal bottom wall of the double hull bears a sump structure comprising a rigid container arranged through the thickness of the bottom wall of the tank and intended to accommodate a suction member of a pump. The rigid container comprises a bottom wall situated at a level further toward the outside than the secondary sealing membrane of the bottom wall of the tank. The sump structure comprises a primary connecting plate surrounding the container, the primary connecting plate having a connecting surface extending parallel to the primary sealing membrane of the bottom wall of the tank, the primary sealing membrane of the bottom wall of the tank being attached in a sealed manner to the connecting surface all around the sump structure.

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 insulating 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 insulating block carries, on the face of same opposite the load-bearing wall, two metal connecting strips arranged in parallel to the sides of the insulating block. The sheets of the membrane carried by the insulating block are welded to the strips. The connecting strips are rigidly connected to the insulating block carrying same. The sheets each have at least two orthogonal folds parallel to the sides of the insulating blocks, the folds being inserted into the gaps formed between two insulating blocks.

The invention relates to an insulation arrangement for a liquefied gas carrying ship wherein the ship has a primary barrier for containing a liquefied gas and a hull, and where the hull is spaced from said primary barrier to define a void between the hull and primary barrier. The hull is insulated with an insulation layer, said layer comprising a plurality of individual tessellating insulation panels.

This invention relate to a tank, for transport and/or storage of cryogenic gases where the tanks insulation (1) are on the inside of the tank. The tanks insulation (1) has a leak proof layer (2) made of carbon fiber, fiberglass, plastic, metal or similar leak proof material.

The disclosure relates to a corner structure which is suitable for a sealed and thermally insulating tank for storing a fluid comprising a secondary thermal insulation barrier which is retained on a carrier structure, a secondary sealing membrane, a primary thermal insulation barrier and a primary sealing membrane which is intended to be in contact with the fluid contained in the tank, the corner structure comprising: a first panel and a second panel forming a corner of the secondary thermal insulation barrier, and comprising an external face intended to move opposite the carrier structure and an internal face; a corner arrangement of the secondary sealing membrane, which arrangement is fixed to the first and second panels; a first insulating block and a second insulating block of a primary thermal insulation barrier which are fixed to the first and second panels, respectively, and which rest against the corner arrangement of the secondary sealing membrane; and a corner of a primary sealing barrier comprising a first wing and a second wing which are fixed to the first and second insulating blocks, respectively.

The disclosure relates to a sealed and thermally insulating tank for storing a fluid, said sealed tank comprising an outer support structure, a thermal insulating barrier retained on the support structure, and a sealing barrier supported by the thermal insulating barrier. In one embodiment, the thermal insulating barrier comprises a corner structure positioned at an intersection between a first and a second wall of the support structure, the corner structure comprising a first and a second insulating panel, each having an outer surface positioned facing the support structure, an inner surface provided with a member for securing the sealing membrane, and lateral edges, the first panel having an outer surface resting against the first wall of the support structure and a lateral edge resting against the second wall of the support structure, the second panel having an outer surface resting against the second wall of the support structure and a lateral edge resting against the outer surface of the first panel.

An internal bottom wall of the double hull bears a sump structure comprising a rigid container arranged through the thickness of the bottom wall of the tank and intended to accommodate a suction member of a pump. The rigid container comprises a bottom wall situated at a level further toward the outside than the secondary sealing membrane of the bottom wall of the tank. The sump structure comprises a primary connecting plate surrounding the container, the primary connecting plate having a connecting surface extending parallel to the primary sealing membrane of the bottom wall of the tank, the primary sealing membrane of the bottom wall of the tank being attached in a sealed manner to the connecting surface all around the sump structure.
