Arrangement method of ship bilge structure, ship bilge structure and ship

Abstract

The invention discloses an arrangement method of a ship bilge structure, the ship bilge structure and a ship. The arrangement method of the ship bilge structure comprises the following steps: S10, the height of a bottom side cabin of a ship is controlled to be smaller than 6 m, a plurality of reinforcing rib plates are arranged on one side of an outer plate, one side of a cabin bottom plate and one side of an inner shell inclined plate, and the reinforcing rib plates on the inner shell inclined plate and the cabin bottom plate are adjusted; S20, the end, away from the inner shell inclined plate assembly, of the outer plate assembly and the end, away from the inner shell inclined plate assembly, of the cabin bottom plate assembly are connected with arc plates, round holes are formed in the positions between the inner shell inclined plate assembly and the arc plates, and round panels are welded to the inner side walls of the round holes; and S30, a reinforcing plate is welded to the reinforcing rib plate, closest to the circular hole, in the outer plate assembly. The arrangement steps of the bilge structure are simplified, materials are saved, and the arrangement difficulty of the bilge structure is lowered.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship bilge structure arrangement method, a ship bilge structure adopting the arrangement method, and a ship including the ship bilge structure. Background technique [0002] Usually, in order to reduce the overall weight of the hull structure, lightening holes are arranged in the structure of the ship's bilge. Generally, such as figure 1 As shown, the ship bilge structure includes the inner sloping plate 1', the outer plate 2' and the bottom plate 3'. The outer plate 2' and the bottom plate 3' are connected by an arc structure 4'. The ends are respectively connected to the outer plate 2' and the bottom plate 3'. The bilge structure of a large oil tanker in the prior art has the following disadvantages: 1. The sloping plate 1' inside the shell and the hopper tank in the bilge are high in height, so it is necessary to set up a manual inspection channel at the position correspondi...

AI Technical Summary

Problems solved by technology

The bilge structure of a large oil tanker in the prior art has the following disadvantages: 1. The sloping plate 1' inside the shell and the hopper tank in the bilge are high in height, so it is necessary to set up a manual inspection channel at the position corresponding to the outer plate 2' of the bilge; 2. The heavy hole 5' is mainly offset by a certain distance from the outer plate 2', the bottom plate 3' and the sloping plate 1' inside the shell to form a triangular lightening hole 5'. The ship bilge structure of this structure needs to be located in the lightening hole. Only by adding more webs and reinforcing plates on the frame plate at the 5' circumference can the structural strength of the ship's bilge structure be ensured. The structure is complex, difficult to construct and low in efficiency.
