Definitions

• the invention relates to a container for the transport and storage of liquids with a device for damping the fluid movement, wherein the
• Damping device introduced in the form of a supporting structure in the container and is positively adapted to the geometry of the container.
• Such slosh plates are usually integrated in tankers directly into the construction of the tank walls. They then often form orthogonal to the tank wall aligned protruding sheets, which are arranged both on the tank bottom and on the tank walls and exert a damping effect on the liquid movement transverse to the flow direction.
• a disadvantage is that the effect of the slosh plates, which are usually designed as ribs, are limited only to the areas adjacent to the tank walls of the tank and so the central region of the tank, in which the liquid movements are strongest is not dampened by slosh plates. Sufficient fluid damping throughout the tank would require very large slosh plates that would be associated with a relatively high cost and a reduction in the tank volume available to the fluid.
• Object of the present invention is to provide such a container in such a way that the slosh movement is optimally damped even in the simplest and most cost-effective manner, if this container is a membrane tank.
• the invention solves this problem by providing that in such a container, the structure is inserted without fixed connections to the walls in the container or tank and its elements are releasably connected to each other.
• the framework itself preferably consists of pipes, fasteners, horizontal, oblique and vertical sheets.
• the invention enables the installation and the optimal positioning of slosh plates in the tank, without a firm connection with the tank wall has to be made, and is therefore particularly suitable for the retrofitting of tanks, without structural changes to the tank would be required. It is therefore particularly suitable for retrofitting of cryogenic tanks, for example in LNG tankers, where additional connections to the Tank would lead to a deterioration of the insulation effect and are therefore undesirable.
• the device according to the invention ensures that the
• Fluid movements are optimally damped even when the tanks are only partially filled.
• hollow pipes are connected by means of plug-in connections to the supporting structure and there are attached to the pipes and connecting elements Schwappbleche which are arranged both horizontally, and obliquely and vertically to the tank.
• This design allows an optimal positioning of the sheets for the particular application.
• the entire construction rests on sacks, which are preferably filled with a bed consisting, for example, of polystyrene balls or similar materials softer than the tank wall and resistant to cryogenic media.
• molded parts can also be used instead of the sacks. Due to the positive fit with the tank geometry slipping of the structure in the tank is not possible and damage to the tank can be avoided.
• the device provided in the container according to the invention has a modular construction and can thereby be introduced into any desired tank, for example also into cubic tanks. Because no additional
• Attachment points must be present in the tank, such tanks can be equipped with such a damping device in retrospect.
• the intended use in the inventive device non-movable components also avoids uncontrolled contact with the container or tank walls and thus their damage. Necessary maintenance and the associated costs are minimized in this way.
• the inventively provided device does not form thermal bridges, as solid connections to the tank wall, such as Versehraubungen or welding, are not provided. Since the damping device is arranged largely insulated from the tank wall, the heat additionally introduced into the container by this device is reduced to a minimum.
