Definitions

• the invention relates to a device for storing an independent tank for liquefied gas, in particular LNG, in a ship according to the preamble of claim 1, as well as a particularly suitable for the device biloben pressure tank.
• Liquid natural gas places special demands on the design because its temperature is lower than that of most technical liquefied gases.
• bilobe tanks which have the shape of two parallel and intersecting circular cylinders.
• Such biloben tanks have been used for some time, because they use the space more efficient than circular cylindrical tanks while preserving their advantages in terms of mechanical stability.
• Ethylene charge temperature about -100 ° C
• At lower temperatures, e.g. occur in liquid natural gas pushes the known construction to its limits, and because of the temperatures themselves and additionally because of the higher thermal expansion coefficient of the tank material, which must be used for cryogenic liquefied gases.
• the invention has for its object to provide a device of the type mentioned, which is not only suitable for circular cylindrical, but also for bilobe tanks that are to be filled with particularly cold, so-called. Tiefkalten liquid gases, especially LNG.
• the inventive device foundation and saddle form no structural unit. Rather, both are separated from each other and have two mutually parallel planar surfaces, between which the accordingly also level thermal insulation layer is located.
• the insulating layer with two flat boundary surfaces within this relative movements can now take place to compensate for thermal stresses in all directions, ie just transverse to the longitudinal direction of the tank, so that it for the functioning of the construction on the cross-sectional Shape of the tank and, because the tensions are not collected, but reduced, no longer reaches a minimum temperature of the liquefied gas.
• the device according to the invention is therefore particularly predestined for the storage of biloben tanks for the transport of LNG.
• the insulating layers of the device according to the invention are preferably made of a pressure and shear-resistant material, so that they can withstand not only the load of the filled tank, but also the frictional forces, which are introduced at temperature difference-related relative movements.
• the material may be a polymeric plastic.
• the insulating layers may be fixedly attached to the top of the foundation or fixed to the underside of the associated saddle. In the case of two-part insulating layers, one part is fixedly attached to the upper side of the foundation and the other part to the lower side of the associated saddle, whereby the relative movement between the two takes place within the insulating layer at the flat boundary surfaces of the two parts.
• the first alternative in which each insulating layer is firmly attached to the top of its foundation, so that the relative movement between the saddle and foundation on the underside of the saddle takes place. That is the simplest way of constructing.
• the holder of the tank in the ship to avoid shifts is generally best done with the means of claim 4, wherein the webs prevent sliding movements between the underside of the saddles and the insulating layer held on the foundation each transverse to their longitudinal extent.
• the choice and arrangement of the webs should be chosen so that the degradation of thermal stresses is not restricted. A preferred arrangement in this respect is apparent from the claims 5 and 6.
• the at least one web extending in tank transverse direction on a saddle prevents the movement of the tank on this saddle in the longitudinal direction. On the other saddles or on the other hand, there is no transverse web, so that there the necessary relative movement to reduce the tension in the longitudinal direction is possible.
• the tank secure the longitudinal webs according to claim 6, but allow symmetrical to its two sides, the relative movements in the transverse direction, which are necessary here for reducing the thermal stresses. If the tank with its longitudinal axis is parallel to the ship's longitudinal direction, the usual and preferred arrangement, the longitudinal webs should be exactly in the middle of the vessel, with respect to its transverse direction, so that the tank centers in the event of any stretching or shrinkage in relation to the ship remains and thus its trim is not disturbed.
• the fuses which prevent the lifting of the tank from the foundations in rough seas, are preferably designed according to claim 7. They are also located in the transverse center of the ship. This has over a conceivable arrangement on both sides of the tank the advantage that it at The discharge of the tank does not lead to jamming between the tank and the hull due to a slight concave curvature of the bottom of the ship, which indeed occurs during unloading:.
• tanks can be stored in each case by means of a device according to the invention in a ship.
• the design of the ship in this respect depends on customary, known criteria.
• a tank according to the invention also with other liquid media, e.g. To fill chemicals to ensure the economic exploitation of the ship.
