Definitions
- the invention relates to a tank for the transport and / or storage of liquefied natural gas, methane, propane, butane, ethylene or other cryogenic liquids. More particularly, the invention relates to tanks that are suitable for placement on board ships. It also refers to tanks that can be used as land tanks.
- Cryogenic fluids are transported or stored at very low temperatures. This temperature is about minus 164 degrees Celsius for liquefied methane (LNG). For liquefied ethylene (LEG) it is minus 103 degrees Celsius.
- Liquefied gas tankers with membrane tanks are known in which a membrane of the tank is held in the ship's hull.
- liquefied gas tankers are known with self-supporting tanks. It is also known to produce the tanks for weight saving of aluminum.
- EP 1 723 053 B1 describes an aluminum tank for storing LNG or similar media at very low temperatures.
- the tank consists at least substantially of prefabricated construction elements of less different types.
- the construction elements have planar elements of mechanically extruded aluminum profile elements, which are used as jacket panels of the tank.
- the profile elements have a planar part and a stiffening part, wherein the stiffening part extends substantially perpendicular to the planar part.
- the profile elements are welded together at their planar parts by means of a friction welding process to form the planar elements.
- the planar elements are provided with longitudinal and / or transverse stiffeners, which are made of mechanically extruded aluminum profile elements, which are welded together by means of the friction-welding process.
- the stiffeners extend over the insides of the planar elements of the tank, being in the longitudinal direction of the aluminum profile elements
- CONFIRMATION COPY extend or extend transversely across these.
- the stiffeners extending across the panels must be fixed either on the ends of the stiffening parts or on the insides of the planar parts of the profile elements. This limits the strength of the connection of the stiffeners with the planar elements.
- WO 2006/00 17 11 A2 describes a tank for storing liquids, in particular at very low temperatures, which has outer plates which form at least part of the roof, the side walls and the bottom.
- the tank has an internal cell structure with fluid connections between the cells of the cell structures. At least part of the outer panels have a layered sandwich structure.
- the inner cell structure serves as a support and anchoring for the outer plates.
- the cell structure may be connected directly to the inner wall of the plates or to fasteners arranged in the sandwich structure.
- the inner cell structure may be connected to a flange which is fixed to the outer wall and projects into the tank.
- the flange may protrude from a connecting element having two U-shaped grooves in which elements of the outer wall are inserted. This compound is stable against stresses in the tensile and compressive direction of the cell walls. However, it is not stable against forces acting on the structure across the flange.
- WO 2008/10 30 53 AI describes a double-hull tank with inner and outer walls and inner horizontal supports.
- the tank walls consist of horizontal profile beam sections with two parallel flanges, which are connected by a web.
- the profile carrier sections are mounted one above the other and welded together on the adjacent longitudinal sides of their flanges. At the ends they are connected by connecting pieces.
- the profile carrier sections bear from the inner wall projecting Ribs.
- On the ribs are welded plate plates to which the supports are attached.
- the knee panels bridge the weld joints between the narrow sides of horizontally arranged profile support sections. The attachment of the supports to the tank walls is stable against tensile and compressive loads in the direction of the supports, but not against forces acting transversely to the ribs or barbs.
- the prior art tanks are not suitable for use on board a liquefied gas tanker under sea conditions due to their limited strength. They are also not particularly suitable for use as a land tank, as they are not sufficiently stable to loads caused by liquid, wind and other influences.
- the object of the invention is to provide a more stable tank for the transport and / or storage of cryogenic liquids.
- the tank according to the invention for the transport and / or storage of liquefied natural gas, methane, propane, butane, ethylene or other cryogenic liquids has a tank shell,

- tank shell further comprises extruded aluminum joint profiles each having a joint profile plate forming part of the tank shell and a connecting profile land protruding from the inside of the joint profile plate, the joint profiles being disposed between adjacent tank shell panels extending perpendicular to the tank shell profiles the longitudinal sides of the connecting profile plates are welded by butt welds with the narrow sides of TankhüUenprofilplatten,
- Support plates in the corners between the panels and the frame members, which are welded at one edge with a Tankhüllenprofilsteg and at another edge with a frame member.
- the tank shell is composed essentially of tank shell panels and connecting profiles, which are arranged between the tank shell panels.
- the tank shell panels are composed of parallel tank shell profiles, the TankhüUenprofilplatten and from their inner sides projecting tank shell profile webs have.
- the tank cover profiles are welded together on the long sides of the Tankhüuenprofilplatten by butt welds.
- the connection profiles have connection profile plates and connecting profile webs projecting from their insides.
- the connection profiles are disposed between adjacent tank shell panels, extending perpendicular to the tank shell profiles of the tank shell panels.
- the connection profile plates are on their long sides by Butt welds welded to the narrow sides of the Tankhüenprofilplatten the adjacent tank shell profiles.
- the tank cover profiles and the connection profiles are made of extruded light metal. Compared to profiles made of welded components, they are therefore not warped from the outset by heat input and impaired in their strength.
- the light metal is aluminum or an aluminum alloy.
- the frame members are welded to projecting into the tank ends of the connecting profile webs. Further, the frame members are fixed at the edges by means of support plates which are welded at the edge to a tank shell profile web and the respective frame member.
- the tank envelope profile is relevant to the tank shell profile plate adjacent part of the tank shell profile web.
- Decisive for the strength of the connection profile is the part of the connection profile web adjacent to the connection profile plate.
- the arrangement of the welds the heat input and the delay and the impairment of the base material in the relevant for the strength areas of the tank shell profiles and the connection profiles are kept low.
- the support plates can be advantageously arranged in the plane of the tank shell profile webs, which is aligned perpendicular to the plane of the adjacent connection profile web.
- the tank according to the invention has a high resistance to contamination by liquid filled, swell, wind influences, etc. and a high durability. It is therefore particularly suitable for use on liquefied gas tankers and as a land tank.
- the tank can be designed with any dimensions and filling volumes. Due to its high strength, it is also suitable for tanks with very large filling volumes.
- the Tankhüenprofilkopf increases the stability of the tank shell profiles and reduces the heat transfer into the base material of the tank shell profile web when welding the support plates.
- the connection profile head increases the stability of the connection profiles and reduces the heat transfer into the base material of the connection profile web when welding the frame elements.
- the Tankhüuprofilprofilkopf and / or connecting profile head is preferably a Tankhüllenprofilfiansch and / or Mattsprofilflansch which is arranged perpendicular to the tank shell profile web and / or connecting profile web.
- the tank shell profile webs and / or the connecting profile webs at the outer ends and / or the support plates adjacent to the imaginary vertex of the edges on grooves greatly reduce voltage spikes.
- the tank shell profiles and / or the connection profiles have a mounting rib projecting from the outside of the tank shell profile plate and / or connection profile plate.
- outer structural elements of the tank are welded to the outer ends of mounting ribs. Due to the mounting rib, the heat input into the tank cover profiles and / or connection profiles when Welding to external structural elements is reduced and loss of strength is avoided.
- the outer structural elements holding means for a tank storage element and / or for a tank insulation and / or an outer safety barrier of the tank may be formed by plates welded between the mounting ribs.
- the safety barrier serves to monitor the tightness of the tank shell and absorb leaks in the event of an accident.
- the tank cover panels comprise intermediate plates, which are arranged between adjacent tank envelope profiles and are welded at longitudinal edges via butt welds with longitudinal edges of TankhüUenprofilplatten.
- the dimensions of the tank shell profile webs and / or connecting profile webs can be selected in the dimensioning of a tank according to the invention from a strength point of view. For given dimensions of these webs, the possible dimensions of the TankhüUenprofilplatten and the Vietnamesesprofilplatten are subject to restrictions due to the application of the extrusion process. These restrictions can be compensated by using intermediate plates.
- the connecting profiles which connect two tank shell panels arranged in the same plane, are essentially T-shaped.
- the connection profile plates of a connection profile extend in a common plane.
- connection profiles on Tankecken on connection profile plates which are at an angle to each other Have plate portions, wherein the angle of the two plate portions corresponds to the angle between the Hauptausdehnungslegien of the two adjacent, interconnected by the connecting profile tank shell panels and the connecting support web between the two plate portions protrudes into the tank.
