Abstract

The utility model discloses a novel six-leg platform jacket. The novel six-leg platform jacket comprises six jacket legs, and a steel pile penetrates through the jacket legs; the jacket legs are vertically arranged, the upper ends of the six jacket legs are sequentially connected through supporting rods to form a regular hexagon I, and the lower ends of the six jacket legs are sequentially connected through supporting rods to form a regular hexagon II; the length of each side of the regular hexagon I is smaller than the length of each side of the regular hexagon II. According to the novel six-leg platform jacket, a second shaft of the jacket and a third shaft of the jacket can be connected or disconnected as required; the jacket is in split installation through a small floating crane when the second shaft of the jacket and the third shaft of the jacket are disconnected, and cost for installation at sea can be saved; compared with a convectional jacket, the environment load can be reduced by 10 percent, and the pile head force can also be reduced properly; a left platform block and a right platform block are both stably supported, and an extra module supporting frame is not needed. Each single block can be installed without a super large floating crane, and cost for installation at sea can be substantially saved.

Description

A kind of novel 6 leg platform jackets
Technical field
The utility model relates to a kind of novel 6 leg platform jackets.
Background technology
For the exploitation of the offshore oilfield within the scope of 40 meters of depth of water, platform structure mainly adopts jacket form.According to the function of platform, the factors such as the quantity of top installations and facilities, area and weight, determine suitable floor space, determine corresponding working platform point scale, the final form of determining lower guide pipe support, conventional jacket platform is generally 4 legs, 6 legs and 8 leg forms.Platform for the middle homalographic with certain production processing capacity, according to the layout of installations and facilities, adapt to the platform of selecting 6 legs, but adopt traditional 6 leg jacket platform forms, platform chunk need to adopt large-scale floating crane (actual Lifting Capacity need be greater than 3500 tons) to carry out integral hoisting, or need the extra piecemeal lifting that module support frame carrys out implementation platform chunk that increases, will significantly increase offshore construction expense.Therefore eight smaller leg jacket form platforms of employing scale are finally selected in this type of oil field development, are easy to marine installation, but have significantly increased structure engineering quantity, have increased investment.
Utility model content
The purpose of this utility model is to provide a kind of novel 6 leg platform jackets, and then provides a kind of suitable platform area to meet to be with certain production processing capacity, and platform chunk just can adopt more small-sized crane barge to carry out piecemeal installation without increasing module support frame; Simultaneously novel six leg jackets of the utility model can integral installation, and also detachable is two 3 leg jackets, adopts more small-sized crane barge to install, and reduces and employs large-scale floating crane resource, reduces cost of investment, the economic benefit of raising project.
Novel 6 leg platform jackets provided by the utility model, comprise 6 jacket legs, and piling bar runs through described jacket leg;
Described jacket leg all vertically arranges, and the upper end of 6 described jacket legs is in turn connected to form a regular hexagon I by support bar, and the lower end of 6 described jacket legs is in turn connected to form a regular hexagon II by support bar; And the length of side of described regular hexagon I is less than the length of side of described regular hexagon II.
In 6 above-mentioned leg platform jackets, between described regular hexagon I and described regular hexagon II, be provided with 1~2 leveling course, the orthohexagonal plane of described leveling course for being in turn connected to form by described support bar by 6 described jacket legs, leveling course connects each spud leg, transmits horizontal loading.。
In 6 above-mentioned leg platform jackets, between described leveling course, by diagonal brace, connect, by diagonal brace, connect each spud leg, transmit vertical load.
In 6 above-mentioned leg platform jackets, in described regular hexagon I, described regular hexagon II and described leveling course, be equipped with 2 struts, described strut connects 2 described jacket legs that are oppositely arranged, and described regular hexagon I, described regular hexagon II and described leveling course are separated into respectively to 2 symmetrical triangles, the relative spud leg of described strut level connection joint, and make 6 leg jackets can form 23 relatively independent leg jackets.
In 6 above-mentioned leg platform jackets, described regular hexagon II is provided with a mud mat, and when described mud mat meets jacket installation, antiskid moves the ability with sedimentation.
Platform chunk is installed on to the upper end of the utility model 6 leg jacket platforms, obtains a kind of 6 novel leg jacket platforms.
The novel 6 leg platform jackets that the utility model provides are owing to taking above technical scheme, and it has following characteristics:
1, the position of jacket leg is different from tradition, and novel 6 leg platform jackets are in the plane of operating point, and 6 leg posts form regular hexagon;
2, jacket 2. axle can be connected as required or not connect with 3. between centers; While not connecting, jacket can adopt small-sized crane barge to carry out partial installation, can save marine mounting cost;
3, compare conventionally form jacket, environmental load can reduce approximately 10%, and pile crown power also can have suitable minimizing;
4, there is stable support two of platform chunk left and right, do not need additionally to increase module support frame.Chunk monolithic can not adopt super large floating crane to install, and can significantly save marine mounting cost.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following instance.
As illustrated in fig. 1 and 2, the novel 6 leg platform jackets of the utility model, comprise 6 jacket legs 1, and piling bar runs through jacket leg 1 squeezes into seabed.Article 6, jacket leg 1 is vertical setting, article 6, the upper end of jacket leg 1 is in turn connected to form a regular hexagon I by support bar 2, article 6, the lower end of jacket leg 1 is in turn connected to form a regular hexagon II by support bar 2, and the length of side of regular hexagon I is less than the length of side of regular hexagon II, specifically by 6 jacket leg 1 slant settings are realized.Regular hexagon II is provided with a mud mat 4, has antiskid and move the ability with sedimentation during jacket installation.
As shown in Figure 2, Figure 3 and Figure 4, along on the length direction of jacket leg 1, be provided with 2 leveling courses between regular hexagon I and regular hexagon II, each leveling course is the orthohexagonal plane for being in turn connected to form by support bar 2 by 6 jacket legs 1 all.Between each leveling course, by diagonal brace, connect.
As shown in Figure 5, in regular hexagon I, regular hexagon II and 2 leveling courses, be equipped with 2 struts 3, strut 3 connects 2 jacket legs 6 that are oppositely arranged, and regular hexagon I, regular hexagon II and 2 leveling courses are separated into respectively to 2 symmetrical stable triangles.
The novel 6 leg platform jackets that the utility model provides, all have symmetry in every respect, and in marine environment, owing to need to considering the wave current power of all directions, this structure is more balanced than the pile crown power of six traditional leg platform structures.
Structure as shown in Figure 3, is appreciated that as being comprised of two three leg platforms, and the support bar in the middle of can connecting in the situation that crane barge ability meets lifting requirements, forms six complete leg platform structures.Adopt water (as shown in Figure 6) under integral hoisting.The in the situation that of crane barge scarce capacity, also can not connect support bar, form two independently three leg platforms, adopt crane barge to lift respectively lower water (as shown in Figure 7) is installed.This optional installation form is relatively less to the restriction of crane barge, and workability is wider, highly beneficial for the ocean engineering industry of crane barge resource anxiety.
