1. System for support of a cargo tank (4, 40) in a vessel (41), comprising:
a cargo tank having a generally flat and generally flexible bottom; substantially evenly distributed underneath the bottom of the tank are support elements (13); each comprising an insulation layer (15), wherein substantially all vertical force from the tank is transfer ras pressure generally evenly distributed from the contents of the tank, through the bottom structure of the vessel and on to water pressure exerted on an outer bottom (10) of the vessel (41); the cargo tank (4, 40) comprising at least two pairs of tank pressure faces (38) fastened to a tank shell (23) of said tank wherein at least one pair of said tank pressure faces (38) is arranged transversely and wherein at least one pair of said tank pressure faces (38) is arranged longitudinally in the vessel (41); an insulation layer (26) arranged proximate to each of the tank pressure faces; a corresponding hull pressure face (39) arranged proximate to each of the insulation layers on the other side of each of the insulation layers (26), each hull pressure face fastened to a ship side (19) or to a bulkhead (5); and wherein each the tank pressure face (38) and the corresponding hull pressure face (39) is aligned so that an orthogonal line of force is directed generally tangentially to a middle of the tank shell (23) so that the insulation layers (15, 26) can transfer pressure without transferring substantial bending moment from the support loads to the cargo tank structure or to the bottom of the vessel and, at the same time, thermally insulate between the cargo tank and the vessel. |
