8. A tank container comprising a vessel covered by an insulation arrangement, and a framework; wherein the vessel is connected to the framework by a clamping device which comprises a sandwich structure with at least one first plate element connected to the framework, at least one second plate element connected to the vessel, and at least one insulating plate element arranged between the first and the second plate element, wherein the first, second and insulating plate elements each have at least one opening, and wherein the first, second and insulating plate elements are interconnected by a joint element traversing corresponding openings of the first, second and insulating plate elements,
wherein the insulating plate element is manufactured from a fiber reinforced plastic material comprising a PTFE material.
9. Tank container comprising a vessel covered by an insulation arrangement, and a framework; wherein the vessel is connected to the framework by a clamping device which comprises a first sandwich structure with at least one first plate element connected to the framework, a second sandwich structure with at least one second plate element connected to the vessel, and a load-bearing connecting plate extending in parallel to the first and second plate element and having a first end overlapping the first plate element and a second end overlapping the second plate element; wherein the first sandwich structure comprises the first plate element interconnected to the first end of the load-bearing connecting plate by at least one joint element traversing the first plate element and the load-bearing connecting plate, and at least one insulating plate element arranged between the first plate element and the load-bearing connecting plate; and wherein the second sandwich structure comprises the second plate element interconnected to the second end of the load-bearing connecting plate by at least one joint element traversing the second plate element and the load-bearing connecting plate, and at least one insulating plate element arranged between the second plate element and the load-bearing connecting plate.
10. Tank container of claim 9 , wherein the insulation arrangement comprises at least one insulation layer which comprises aerogel.
11. Tank container of claim 10 , further comprising at least one outer cover sheet enclosing the insulation arrangement.
12. Tank container of claim 11 , wherein the insulation arrangement comprises at least one insulation layer set comprising at least two insulation layers which comprise aerogel and at least one radiation shield layer between the at least two insulation layers.
13. Tank container of claim 12 , wherein the insulation arrangement comprises at least two insulation layer sets comprising aerogel insulation layers and at least one radiation shield layer, and at least one vapor barrier layer between the at least two insulation layer sets.
