Embodiment Construction

[0039] In FIG. 1 , reference numeral 1 generally designates a transport tank. The transport tank 1 consists of a tank bottom 2 , a cylindrical tank peripheral wall 3 and a tank top 4 . The tank bottom 2 is designed flat and is connected to the lower deck 7 of the hull, which is not shown in further detail, by inserting an insulating layer 6 . The top 4 of the tank is connected to the upper deck 9 of the hull by inserting an insulating layer 8 . The tank circumferential wall 3 is partially supported towards the bottom by deformable support means 12 . The support means 12 engages on the bottom part of the tank peripheral wall 3 . Deformation absorbers 15, 16 are accommodated in the tank walls. Here the deformation absorbers 15, 16 are formed as segments with a cross-section in the shape of a sector (quarter circle shape) and are respectively between the tank bottom 2 and the tank peripheral wall 3, or between the tank top 4 and the tank peripheral wall 3 extend between. The...

Abstract

A ship (20) with one or more liquid transport tanks (21) arranged in an upright position in a ship's hull, said transport tanks having an axial direction and a circumferential direction, and each transport tank comprising a tank bottom (22) , a tank circumferential wall (25) and a tank roof (23) , the tank bottom being supported on or forming part of a lower deck of the ship's hull. The tank circumferential wall is suspended by its lower and upper ends by means of deformable deformation absorbers (26) between the lower deck and an upper deck (24) of the ship's hull, which deformation absorbers are designed so as to absorb deformations between the ship's hull and the tank circumferential wall at least in the abovementioned axial direction, at least the lower deformation absorber extending in the circumferential direction around substantially the entire circumference of the tank circumferential wall, and at least the lower deformation absorber forming part of the tank wall and being accommodated at the position of the transition between the tank circumferential wall and the tank bottom so as to form a continuous sealing connection between them.

Description

technical field [0001] The invention relates to a ship having one or more liquid transport tanks arranged in the hull for transporting liquid media. Background technique [0002] Existing methods of transporting liquid media such as chemicals, oil and agricultural products mainly use tankers equipped with rectangular cargo tanks integrated with ships, so-called parcel tankers. A cargo tank is a part of a ship's structure, wherein the walls of the cargo tank are formed by the hull, formed transverse and longitudinal bulkheads provided therein, and the deck of the ship. [0003] The disadvantage here is that cracks can develop in the tank walls due to the deformation of the ship in high seas and due to temperature differences. The above-mentioned deformations cause high stress concentrations in the tank, especially at the corner points, which lead to the formation of cracks. If this happens, the opening between two adjacent tanks becomes larger, so that undesired mixing of s...
