Description
Technical field
The present invention relates to shipbuilding technical field, a kind of no swash bulkhead is specifically related to without stull ultra-large type crude oil
Ship.
Background technique
Currently, traditional ultra-large type crude oil carrier structure arranges that peculiar feature is (as shown in Figure 1): there are 2 longitudinal bulkheads,
It is equipped with stull between longitudinal bulkhead, reducing the span of the vertical purlin of longitudinal bulkhead, improves the integrated carrying ability of lateral strong frame frame,
The cargo tank of ultra-large type crude oil carrier is longer simultaneously, and the setting of stull is also beneficial to reduce cargo hold transversely deforming；In addition, traditional super large
For the single oil cargo tank length of type crude oil carrier up to 50m or so, the ratio of oil cargo tank length and captain are more than 0.15, are considered as in oil cargo tank
Lateral swash bulkhead is arranged in middle part, to reduce rocking for Cargo Oil.The setting of swash bulkhead and stull increases shipyard process aspect
Workload, while being also contemplated that swash bulkhead horizontal girder toe-end problem of stress concentration and stull and being connect with longitudinal bulkhead horizontal girder
The problems such as form (as shown in Figure 2), increases the complexity of structure design.

Hereinafter, being illustrated with a kind of specific embodiment, it should be pointed out that described in following implementation it
Structure, technique, selection are only to illustrate the feasibility of embodiment, the intention of there is no restriction the scope of the present invention.
For a kind of no swash bulkhead provided in this embodiment without stull ultra-large type crude oil carrier, 1 spacing of twice longitudinal bulkhead is 4.8m,
6 times of vertical bone spacing are equivalent to, since 1 spacing of longitudinal bulkhead reduces, the lateral opening plate intensity and toughness for serving as vertical purlin is all very big, nothing
2 ' come cross-cut of stull need to be set.Therefore it can cancel the design of stull 2 ', both reduce difficulty of construction, in turn simplify structure design.It should
Kind crude oil carrier is divided into two middle hold, 4,14 side cargo tanks 5, and the two sides of two middle hold 4 are each provided with seven side cargo tanks 5, most
The big long 40.6m in cabin.4 cabin of middle hold length is larger, but since cabin is wide very narrow, and perforated panel is arranged at each strong frame, is not necessarily to volume
Outer setting swash bulkhead 6 ', and 5 cabin of side cargo tank it is long with captain's ratio less than 0.13, no setting is required swash bulkhead 6 '.With traditional super large
Type crude oil carrier is compared, and oil cargo tank of the invention lacks a cargo hold compared with the oil cargo tank of conventional crude oil ship, but passes through appropriate adjustment inner casing
Chine can be such that hatch capacity is held essentially constant, simultaneously as holohedral symmetry design is so that prestowage is more convenient.
, without swash bulkhead without stull ultra-large type crude oil carrier, side cargo tank bulkhead cancels setting swash bulkhead for this, can be from carrying out
The direct calculating for rocking load, saves part manufacturing process, since twice longitudinal bulkhead spacing is smaller, eliminates stull and sets
Meter, also does dog-ear not necessarily like traditional ultra-large type crude oil carrier longitudinal bulkhead at bow, both reduces difficulty of construction, in turn simplify structure
Design, under the premise of not reducing oil cargo tank volume, simultaneously as holohedral symmetry design is so that the prestowage of oil cargo tank is more convenient.
The above is only preferred embodiments of the present invention, are not intended to limit the implementation manners and the protection scope of the present invention, right
For those skilled in the art, it should can appreciate that and all replace with being equal made by description of the invention and diagramatic content
It changes and obviously changes obtained scheme, should all be included within the scope of the present invention.
