Abstract:
1. A ship with one or more liquid transport tanks 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; a tank roof; and a substantially rigid tank circumferential wall extending along said circumferential direction and having a lower end at the side of the tank bottom and an upper end at the side of the tank roof; the tank bottom being supported on or forming part of a lower deck of the ship's hull, wherein the tank circumferential wall is suspended by its lower and upper ends by means of a lower deformable deformation absorber and an upper deformable deformation absorber between the lower deck and an upper deck 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, wherein at least the lower deformation absorber extending in the circumferential direction around 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 a position of a transition between the tank circumferential wall and the tank bottom so as to form a continuous sealing connection between them, wherein the axial direction is parallel to a vertical center line of the tank circumferential wall between the tank bottom and the tank roof, wherein the circumferential direction is in a tangential direction of the tank circumferential wall around the axial direction and the vertical center line, wherein the deformation absorbers are designed in such a deformable manner that deformations of the ship's hull are absorbed by deformation of the deformation absorbers with the tank circumferential wall substantially retaining its shape and not crumpling, wherein the deformation absorbers have freedom to deform at least in the axial direction both axially upward as well as axially downward, and wherein the deformation absorbers have freedom to deform in the axial direction around the entire circumference of the deformation absorbers.
