Abstract
The invention relates to a cabin wall form, and discloses a fold-line cabin wall suitable for a floating production oil storage device. The fold-line cabin wall comprises a fold-line side longitudinal cabin walls which are arranged between two transverse cabin walls in the middle of a ship and have symmetrical left and right boards; the fold-line side longitudinal cabin wall on each side comprises a middle straight cabin wall as well as front and back oblique cabin walls; the length between the two transverse cabin walls is 1/3 to 1/4 of the ship length; the straight cabin walls are 1-2 meters closer to the a middle longitudinal cabin wall compared to an original side longitudinal cabin wall of the conventional floating production oil storage device; included angles between the oblique cabin walls and a ship length direction are 10-15 degrees. By adopting the fold-line cabin wall, the conventional ship concept is broken through; a fold-line cabin wall design is adopted, the cabin volume of an oil tank is reduced in the middle of the ship, and the volume of the oil tank is increased on the head and the tail parts of the ship, so that the structural weight distribution of the a ship body is changed, the weight of the middle of the ship is reduced, a sagging bending moment is lowered, the floating type oil production storage device is more reasonable in design, and the aims of lowering a still water bending moment and reducing the steel usage amount of the floating type oil production storage device can be fulfilled.
Description
Technical field
The present invention relates to a kind of bulkhead form, specifically, relate to a kind of bulkhead being applicable to floating production storage unit.
Background technology
FPSO (Floating Production Storage and Offloading, i.e. Floating Storage Unloading Device) is offshore oil
One of Main Patterns of exploitation, is widely used in the crude oil production in each marine site, the world, storage and outer defeated.FPSO hull
Structure is generally according to conventional oil tanker design, but FPSO is different, especially in full load conditions from the loading condition of conventional oil tanker
Under, weight concentrates on midship, afterpeak tank and first Peak Tank due to zero load, in moment of flexure of hanging down be far longer than conventional oil tanker, it is necessary to
Vertical moment of flexure in reduction.Owing to Loading conditions is different, using conventional oil tanker design, FPSO will increase the modulus of section, and steel make
Consumption is huge.
Summary of the invention
The technical problem that moment of flexure is bigger the present invention is to solve hang down in current floating production storage unit, proposes one and is applicable to
The broken line type bulkhead of floating production storage unit, by reducing oil cargo tank volume of compartment at Chuan Zhongchu, increases Cargo Oil in stem and afterbody
Cabin volume of compartment, improves weight of ship distribution.
In order to solve above-mentioned technical problem, the present invention is achieved by following technical scheme:
A kind of broken line type bulkhead being applicable to floating production storage unit, including being arranged between midship two transverse bulkhead and left and right
The fold-line edge longitudinal bulkhead that the side of a ship is symmetrical, the described fold-line edge longitudinal bulkhead of every side includes middle straight bulkhead and the oblique cabin front and back arranged
Wall, makes the oil cargo tank volume of compartment in ship reduce, and the oil cargo tank volume of compartment of stem and afterbody increases.
Wherein, a length of 1/3-1/4 captain between two transverse bulkheads.
Wherein, original limit longitudinal bulkhead of the described more traditional floating production storage unit of straight bulkhead is near centerline bulkhead 1-2 rice.
Wherein, described sloping bulkhead is 10-15 degree with the angle in captain direction.
The invention has the beneficial effects as follows:
The present invention has broken away from the constraint of traditional boats and ships theory, uses broken line type bulkhead design, reduces oil cargo tank volume of compartment at Chuan Zhongchu,
Increase oil cargo tank volume of compartment in stem and afterbody, thus change weight of ship distribution, make weight reduction in ship, and then reduce
In hang down moment of flexure, the design making floating production storage unit is more reasonable, it is possible to reduce still water bending moment, reduces Floating Production
The purpose of Fuel Tanking Unit steel usage amount.
Accompanying drawing explanation
Fig. 1 is the structural representation of broken line type bulkhead provided by the present invention.
In figure: 1, fold-line edge longitudinal bulkhead；11, straight bulkhead；12, sloping bulkhead；2, original limit longitudinal bulkhead；3, vertical cabin in
Wall；4, outboard plate；5, ship center line；6, transverse bulkhead.
Detailed description of the invention
For present disclosure, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing specifically
Bright as follows:
As it is shown in figure 1, present embodiments provide a kind of broken line type bulkhead being applicable to floating production storage unit, this broken line type
Bulkhead includes the fold-line edge longitudinal bulkhead 1 in the range of being arranged between midship two transverse bulkhead 6, the length between two transverse bulkheads 6
Generally 1/3-1/4 captain's (i.e. side transverse bulkhead 6 is 1/6-1/8 captain with the distance of ship center line 5).Both sides fold-line edge indulges cabin
Wall 1 port and starboard centered by centerline bulkhead 3 is symmetrical, includes the straight bulkhead 11 of middle setting and the most symmetrically arranged respectively
Sloping bulkhead 12, original limit longitudinal bulkhead 2 of straight bulkhead 11 relatively traditional floating production storage unit leans on apart from centerline bulkhead 3
Nearly 1-2 rice, sloping bulkhead 12 is 10-15 degree with the angle in captain direction.So, at midship, volume of compartment reduces, stem and tail
Portion's volume of compartment increases, even if the ballast tank volume of compartment between outboard plate 4 and fold-line edge longitudinal bulkhead 1 increases, port and starboard fold-line edge indulges cabin
Oil cargo tank volume of compartment between wall 1 reduces, and to improve traditional structure distribution of weight, moment of flexure of hanging down in minimizing, such that it is able to reduce ship
The body modulus of section, reduces the purpose of steel usage amount.By calculating, use broken line type bulkhead design that hydrostatic can be made curved
Square reduces by 1/3rd, makes longitudinal strength design more reasonable.
Although the preferred embodiments of the present invention being described above in conjunction with accompanying drawing, but the invention is not limited in above-mentioned
Detailed description of the invention, above-mentioned detailed description of the invention is only schematically, is not restrictive, the common skill of this area
Art personnel are under the enlightenment of the present invention, in the case of without departing from invention objective and scope of the claimed protection, it is also possible to make
Go out the concrete conversion of a lot of form, within these belong to protection scope of the present invention.
