Abstract
The utility model discloses a novel six-leg jacket platform. The novel six-leg jacket platform comprises six jacket legs and platform blocks, wherein the jacket legs are vertically arranged, and the connecting lines of the jacket legs form a hexagon along the horizontal face; the jacket platform comprises the two platform blocks, the two platform blocks are both placed at the upper ends of the jacket legs, and each platform block is arranged at the upper ends of three jacket legs which are arranged in a triangle. The novel six-leg jacket platform blocks can be installed independently through a middle floating crane with the actual hoisting capacity smaller than 3000 tons, large floating crane resources in use can be reduced, investment cost can be reduced, and economic benefits of projects can be improved.
Description
Technical field
The utility model relates to a kind of novel 6 leg jacket platforms, belongs to offshore platform field.
Background technology
In recent years along with continuous discovery and the rolling development of marine oil field, most blocks have formed regionl development general layout, according to offshore oil field development scale and newly-built platform, in regionl development, need the functional requirement of bearing, some platform need to arrange the facilities such as power station, oil gas water treatment and life building as the gathering center in region, because relevant equipment, facility are more, 4 conventional leg platform floor spaces often cannot meet the demands, and most platforms that need 6 legs or 8 leg jackets to support provide enough deck spaces.
Adopt traditional 6 leg jacket platform forms, owing to realizing, deck chunk is carried out to piecemeal lifting, can only carry out integral hoisting, therefore must adopt large-scale floating crane (actual Lifting Capacity need be greater than 3500 tons) to carry out integral hoisting.And large-scale floating crane resource scarcity, expense is the twice left and right of medium-sized crane barge, causes operating expenses significantly to increase.
Adopt 8 leg jacket form platforms can realize the smaller resource of employing scale and also than more rich medium-sized crane barge (actual Lifting Capacity is generally at 2000 tons～3000 tons), realize piecemeal lifting.Medium-sized crane barge expense is lower, can effectively reduce installation cost.But 8 leg platforms have increased two legs than 6 leg platforms more, in structural steel amount, also can roll up than 6 leg platforms.
Utility model content
The purpose of this utility model is to provide a kind of novel 6 leg jacket platforms, the utility model is by changing the arrangement of jacket operating point (the platform chunk strong point), solved traditional 6 leg platforms can not piecemeal the problem of lifting, reduce and employ large-scale floating crane resource, reduce cost of investment, improved the economic benefit of project.
Novel 6 leg jacket platforms provided by the utility model, comprise 6 jacket legs and platform chunk;
Described jacket leg is vertically to arrange, and along on horizontal plane, the line of described jacket leg forms a hexagon;
Described jacket platform comprises 2 described platform chunks, and 2 described platform chunks are all positioned over the upper end of described jacket leg, and described in each, platform chunk is all positioned over the upper end of 3 described jacket legs that are triangularly arranged.
In above-mentioned novel 6 leg jacket platforms, the line of described jacket leg forms a regular hexagon, is convenient to described platform chunk and is divided into left and right two and lifts.
In above-mentioned novel 6 leg jacket platforms, 2 described platform chunks are symmetrical set as far as possible, so that reduce the bias of the whole center of gravity of platform chunk, are conducive to the stressed even of jacket and pile foundation.
In above-mentioned novel 6 leg jacket platforms, be 2 described leg-of-mutton drift angles that are oppositely arranged and be 45 °～75 °, to keep the stability of platform.
The novel 6 leg jacket platforms that the utility model provides are compared with 6 traditional leg jacket platforms, in position, jacket operating point, mounting means and expense, have difference as shown in table 1:
The difference of the novel 6 leg jacket platforms of table 1 the utility model and traditional 6 leg jacket platforms
A kind of novel 6 leg jacket platform chunks provided by the utility model, the line of jacket leg operating point is 6 limit shapes, can obtain following technique effect:
1) be convenient to platform chunk piecemeal and install, increase the flexibility of installing; 2) for the platform of medium-scale floor space, can select 6 leg jacket platform forms;
The novel 6 leg jacket platform chunks that the utility model provides, make platform chunk can adopt medium-sized crane barge (actual Lifting Capacity is less than 3000 tons) to carry out piecemeal installation, can reduce and employ large-scale floating crane resource, reduce cost of investment, improve the economic benefit of project.
Accompanying drawing explanation
Fig. 1 is the top view of jacket leg in the novel 6 leg jacket platforms of the utility model.
Fig. 2 is the top view of the novel 6 leg jacket platforms of the utility model.
Fig. 3 is the elevational schematic view of the novel 6 leg jacket platforms of the utility model.
In figure, each mark is as follows:
1 jacket leg, 2 offshore platform chunk edge lines, 3 offshore platform chunk lifting piecemeal lines, 4 crossbeam center lines, left of 5 offshore platform chunk piecemeal lifting, right of 6 offshore platform chunk piecemeal lifting.
A jacket operating point center to center distance, B jacket operating point center to center distance, C jacket operating point line angle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.
As depicted in figs. 1 and 2, the novel 6 leg jacket platforms that the utility model provides, it comprises 6 jacket legs 1 and platform chunk (not marking in figure), 6 jacket legs 1 are vertically to arrange, and along on horizontal plane, the line of jacket leg 1 forms a hexagon; Jacket leg operating point center to center distance A, B may be selected to be 14m～20m.
The utility model jacket platform comprises 2 platform chunks, and 2 described platform chunks are symmetrical upper ends that are positioned over jacket leg 1 all, and each platform chunk is all positioned over the upper end of 3 jacket legs 1 that are triangularly arranged, as shown in Figure 2.In order to guarantee the stability of platform, jacket leg 1 operating point line angle C (being 2 leg-of-mutton drift angles that are oppositely arranged) is generally taken as 45 °～75 °.
As shown in Figures 2 and 3, offshore platform chunk lifting piecemeal line 3 is in chunk centre position, while making the lifting of offshore platform chunk piecemeal, left 5 of offshore platform chunk piecemeal lifting and the lifting of offshore platform chunk piecemeal all have 3 jacket legs 1 to support for right 6, realize piecemeal lifting.
The novel 6 leg jacket platforms that the utility model provides are generally applicable to weight at the medium-sized offshore platform of 3000t～5000t.Within the scope of this, select above-mentioned novel 6 leg jacket platforms in technical scheme more rationally, economic benefit is more remarkable.
Take certain offshore platform as example, adopt the novel 6 leg jacket platforms of the utility model and adopt the contrast of traditional jacket platform as shown in table 2.
The contrast of the novel 6 leg jacket platforms of table 2 and the traditional jacket platform of employing
