A Design Method of Segmentation for G4 Type Ro-Ro Ship

Abstract

The invention discloses a segment division design method for a G4 type rolling ship. The method comprises the following steps: A, basis: determining a whole ship segmented division principle and requirements; B, carrying out segmented division: dividing a cargo compartment roll-roll area into a bottom larboard segment, a middle segment, a starboard segment, broadside multi-layer larboard and starboard segments, multi-layer deck larboard and starboard segments, multi-layer ramp segments and multi-layer column segments; dividing a cargo hold cabin mixing area into a bottom full-width segment, multiple layers of larboard channel segments and one layer of starboard channel segment which are asymmetrical on the broadside, semi-three-dimensional segments and independent transverse bulkhead segments which are asymmetrical on the left side and the right side of the broadside cabin; dividing a cabin area into a left bulwark segment, a right bulwark segment, an independent complete square channel segment, left-right asymmetric deck segments, a larboard double-shell segment with asymmetric broadside, a starboard double-shell segment with asymmetric broadside, a cabin semi-three-dimensional segment with asymmetric broadside larboard and starboard, and a bottom full-width segment. The method is more scientific, reasonable and convenient, the integrity of the outfitting piece can be improved, and the dock period is shortened.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a segmented and divided design method for a G4 type ro-ro ship. Background technique [0002] The G4 ro-ro ship currently undertaken is a new type of combined ship. There is no experience in the construction of this new type of ro-ro ship at home and abroad. In the past, the ro-ro ship was arranged separately from the container and ro-ro areas, and the structural form of each area was relatively fixed and single. Segmentation is more traditional. The G4-type ro-ro ship is a new type of combined ship with a mixed arrangement of ro-ro areas and container areas. The ro-ro area has the function of loading conventional ro-ro cargo and container cargo at the same time. The layout and structure are complex, and there are many asymmetric structures. The existing segmented design method of ro-ro ships applied to new ro-ro ships has the following defects: [0003] First of all, the layout of ...

AI Technical Summary

Problems solved by technology

[0003] First of all, the layout of the new mixed area of ​​ro-ro, container and engine room is relatively narrow and complex in structure. The traditional division method of ro-ro area and container area is inappropriate and unreasonable

[0004] Secondly, the ro-ro deck of the new type of ro-ro ship is equipped with a large number of container embedded box feet and lashing fixtures. The traditional segmented design method does not consider the segmented seam line to avoid the position of the box feet, which will greatly increase the load on the ro-ro deck. Difficulty in controlling the installation accuracy of container embedded box feet

[0005] Thirdly, the stern structure of the engine room of the new-type ro-ro ship is complex and has many asymmetric structures. The traditional method of dividing the ro-ro ship with symmetrical segments on the left and right sides will increase the number of segments, which will greatly increase the workload of the general group and the dock. The construction period and construction quality control are very disadvantageous

[0006] In addition, according to the traditional division design of ro-ro ships, G4 type ro-ro ships need a lot of tooling materials such as tire frame, support and scaffolding, especially the ro-ro deck area, which will greatly increase the construction cost and increase the safety hazard
