Background
The transverse supporting bulkheads of a container ship are usually of a three-side fixed, freely supported double-deck plate frame structure at the upper end, and the length of the supporting bulkheads generally depends on the arrangement of the size of the ventilating ducts, the staircase and the size of the passageway of the cargo hold. According to the arrangement number of rows and layers of containers in the cabin, a certain number of vertical girders and horizontal girders are required to be arranged in the supporting cabin wall to form a plate frame structure with higher structural strength, so that the load can be effectively transferred to the main structure of the container ship.
The container ship is designed with a large number of transverse supporting bulkheads in the length direction of the ship in order to support the load of the containers on the hatch covers and to reduce the transverse deformation of the hull. In the conventional hull structure design, a plurality of continuous vertical girders and horizontal platforms are arranged on the supporting transverse bulkheads for conveniently designing the guide rail frames and the channels, so that the weight of the supporting transverse bulkheads is increased greatly, and the weight of the whole ship is increased. The trend of large-scale containers has become more and more obvious in recent years, the main dimension of the container ship has also become larger and larger, the number and the weight of the transverse bulkheads have also increased, which has adverse effects on the cost of ship construction and the performance of the ship, and therefore, the design of good supporting bulkheads has greatly improved the performance of the container ship.
