Floating production platform

 

(57) Abstract:

Floating production platform is designed for use primarily in Arctic waters. It contains underwater wodoslawsky module supporting surface module through a rigid supporting columns with binding elements. Rigid support columns, with the connecting elements are made detachable from the underwater module. Achieve enhanced operational capabilities of the platform by improving the means of keeping the upper body for quick departure from dangerous ice conditions in the area and ensure a return to the abandoned place. 1 C.p. f-crystals, 2 Il.

The invention relates to the development of the continental shelf and with the greatest effect can be applied to deep-water platforms with stretched legs.

Known floating drilling platform (application of UK N 1550384, class B 63 B 35/44, 1979), containing the anchor rack of several tubular sections each connected locking and centering elements. Floating platform equipped with wodoslawsky support columns.

The disadvantage of this framework is that it cannot ispolzovaniya floating offshore platform (application Velikobritanii N 1337601, class. B 63 B 35/44, 1973), taken as the prototype of the claimed invention, containing wodoslawsky underwater housing hard bearings supporting surface case with technological equipment. The underwater housing is held stretched by flexible connections attached to the anchors.

Known platform has the disadvantage that it cannot be used in Arctic conditions, as when the ice fields, it is difficult to remove the platform from the moorings and even more difficult to return it to the same place.

The task of the invention is the enhanced operational capabilities by improving the means of keeping the upper body for quick departure from dangerous ice conditions in the area and ensure a return to the abandoned place.

This object is achieved in the floating production platform, containing underwater wodoslawsky module supporting surface of the module by means of rigid supports with the connecting elements, retained tension ties, fixed on a bottom anchor, and support columns, with the connecting elements are made detachable from the underwater module.

The task is achieved by the fact that ve is ragousis with them supporting columns and binding elements.

The proposed platform is shown in the drawing, where:

in Fig. 1 - shows the platform on the side;

in Fig. 2 - section a-a of Fig.2.

Floating production platform contains a surface module, which includes support columns 1, interconnected horizontal wodoslawsky the connecting elements 2. On top of the supporting column 1 supports a working platform 3 with technological equipment.

Horizontal connecting elements 2 mated with the upper deck of the underwater module 4 and the depressions 5.

Underwater module tension ties 6 is held at the project depth of the pond.

In accordance with the project underwater module 4 is transported (towed) to the place of production, where the bottom drops anchor devices (conventionally in the drawing are not shown because of the wide popularity and they are fixed tension connection 6. By mechanical sampling connections 6 underwater module 4 is buried on the depth determined from the conditions under work area 3 maximum possible wave height for a given area. After the underwater module 4 will take its design position, in the area of his productions privacyrelated surface fashion what other connecting elements 2. After surface module koordiniruyutsya with the location of the underwater module 4, is receiving the liquid ballast in the ballast tank surface module. Gradually acquiring negative buoyancy, surface module horizontal connecting elements 2 sits in the recess 5. For reliability in the recesses can be mounted locking devices (not shown), which are not considered in depth, as it does not affect the subject matter.

According to the draft displacement underwater module 4 is selected such that not only keep the working area 3 (which in the operational state of negative buoyancy) above the water surface, but also to create the necessary efforts in the tension ties 6.

These links are placed with some inclination to the external side, which together with the necessary power maintenance provides neatlanta the whole platform from the design position. At the end of operations on the production platform in place on her wound pipelines from production wells and from that moment is her operation. The described platform is designed for operation in Arctic waters. In the case of paulinenhof removed liquid ballast. Surface module acquires positive buoyancy, floats and oboxious in port shelter.

The remaining underwater module 4 is located at a depth of about 50 meters, It can be equipped with the necessary acoustic instruments, for which it's easy to find to resume. Again the operation is repeated coordination surface of the working platform 3 with columns 1 and horizontal connecting elements 2 relative to the subsea module 4, lowering it and connecting pipelines.

1. Floating production platform containing underwater wodoslawsky module supporting surface module through a rigid supporting columns with the connecting elements and the tension ties, mounted on the bottom anchors, characterized in that the rigid support columns, with the connecting elements are made detachable from the underwater module.

2. Floating production platform under item 1, characterized in that on the upper deck of the submarine of the module is made of deepening the number and form adequate to the number and shape mating with them the support columns and the connecting elements.
