Description

Floating Production Equipment {Floating Production Storage Offloading Vessels}

The present invention relates to a floating production facility.

Floating production facilities, such as FPSO and LNG FPSO, produce subsea resources such as crude oil or natural gas from the seabed while floating on the sea.

1 is a view showing a conventional floating production facility. Referring to FIG. 1, the floating production facility includes a hull 10 and various production modules 31, 32, 33, and 34 for producing subsea resources. Production modules (31, 32, 33, 34) are all installed on the upper side of the hull (10).

According to the requirements of the Maritime Corporation and the requirements of ISO, when the above production modules 31, 32, 33, 34 are installed on the upper side of the hull 10, the modules 31, 32, 33, 34), a constant safety gap (SG) must be maintained. Due to this, the length of the hull 10 is increased and an unnecessary empty space (VS) is formed inside the hull 10.

An embodiment of the present invention is to provide a floating production facility with improved space utilization.

According to one aspect of the invention, the hull; and a plurality of production modules mounted on the hull for producing subsea resources, wherein a specific module among the production modules is disposed inside the hull and the others are disposed outside the hull. Production equipment can be provided.

The specific module may be specific to one or more of the production modules, and the specific module may be any one of a cooling module, a power generation module, and a water treatment module.

When the specific module is a cooling module, the cooling module is connected to the sea chest formed in the hull, and seawater inside the sea chest may be used as cooling water.

When the specific module is a power generation module, the power generation module may include any one of a gas turbine generator, a steam turbine generator, and an engine generator.

When the specific module is a water treatment module, a pipe trunk through which a plurality of pipes used in the water treatment module pass and a cable trunk through which a plurality of cables used in the water treatment module pass may be formed above the water treatment module. .

According to an embodiment of the present invention, by arranging some of the production modules conventionally placed outside the upper side of the hull inside the hull, it is possible to prevent the length of the hull from becoming unnecessarily long compared to the prior art. In addition, space utilization can be improved by arranging a specific module among the production modules in an empty space formed inside the hull.

In describing the present invention, if it is determined that a detailed description of related known technologies may obscure the gist of the present invention, the detailed description will be omitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and in the description with reference to the accompanying drawings, the same or corresponding components are assigned the same reference numerals and overlapping descriptions thereof will be omitted. do.

2 is a view showing a floating production facility according to an embodiment of the present invention. Referring to FIG. 2 , the floating production facility 100 according to the present embodiment may include a hull 110 and a plurality of production modules 131 , 132 , 133 , and 134 .

In the hull 110, a storage tank 121 for storing produced subsea resources (eg crude oil, natural gas), a residence 122, a machine room 123, and a turret 124 may be formed.

A plurality of production modules 131 , 132 , 133 , and 134 for producing seabed resources are mounted on the hull 110 . The plurality of production modules 131, 132, 133, and 134 each perform a unique function and operate to produce subsea resources.

In this embodiment, a specific module 134 of the production modules 131 , 132 , 133 , and 134 may be disposed inside the hull 110 . The specific module 134 may be specific to one or more of the production modules 131 , 132 , 133 , and 134 . In this embodiment, it is described that one specific module 134 is disposed inside the hull 110, but two or more specific modules may be disposed inside the hull 110, of course.

For example, the specific module 134 may be disposed between the machine room 123 and the storage tank 121 as shown in FIG. 2 . As another example, the specific module 134 may be disposed between the storage tank 121 and the turret 124 as shown in FIG. 3 . For reference, FIG. 3 is a diagram showing another arrangement of specific modules shown in FIG. 2 .

According to this embodiment as described above, by disposing some of the production modules 131, 132, 133, 134, which were conventionally disposed on the upper side of the hull 110, inside the hull 110, the hull 110 compared to the prior art Unnecessarily long length can be prevented. In addition, space utilization can be improved by arranging a specific module 134 among the production modules 131 , 132 , 133 , and 134 in an empty space formed inside the hull 110 .

Referring to FIGS. 2 and 3 , the specific module 134 may be any one of a cooling module, a power generation module, and a water treatment module. However, this is only an example and the specific module 134 may be a module that performs various other functions.

For example, referring to FIG. 4 , a specific module ( 134 in FIG. 2 ) may be a cooling module 134a. For reference, FIG. 4 is a diagram illustrating a case where a specific module of FIG. 2 is a cooling module.

The cooling module 134a cools heat generated in the process of producing seabed resources. The cooling module 134a disposed inside the hull 110 may be connected to the sea chest formed in the hull 110 . In this case, the cooling module 134a pumps the seawater inside the sea chest to the cooling module 134a through a pump included in the cooling module 134a and uses it as cooling water.

According to the prior art, a cooling module (not shown) is disposed outside the upper side of the hull (not shown). In this case, in order to supply seawater used as cooling water to the cooling module, a caisson (not shown) connecting the cooling module and seawater must be separately attached to the hull, and a special pump (not shown) for pumping seawater to the cooling module through the caisson. ) should be used. The installation of such caissons and the use of special pumps are costly.

However, when the cooling module 134a is disposed inside the hull 110 as in the present embodiment, it is easy to connect the cooling module 134a to the sea chest 127 formed on the hull 110 and the pump of the cooling module 134a (1341), the cost can be significantly reduced because a conventional form can be used.

As another example, although not shown, a specific module ( 134 in FIG. 2 ) may be a power generation module. The power generation module may include any one of a gas turbine generator, a steam turbine generator, or an engine generator.

As another example, referring to FIG. 5 , a specific module ( 134 in FIG. 3 ) may be a water treatment module 134b. For reference, FIG. 5 is a diagram illustrating a case where a specific module of FIG. 3 is a water treatment module.

The water treatment module 134b treats water discharged from a separator (not shown) for separating multi-phase mixtures in the process of producing seabed resources. Since the water discharged from the separator contains a small amount of oil, it is purified in the water treatment module 134b before being discharged to the outside of the hull 110.

The water purified in the water treatment module 134b may be discharged into water or may be re-injected into a well for well recovery.

A pipe trunk 1343 may be formed above the water treatment module 134b. One or more pipelines used in the water treatment module 134b may extend to the outside through the pipe trunk 1343 in an aligned state. In this case, only the pipeline extending to the dangerous area can be aligned and extended through the pipe trunk, so that the pipeline can be stably managed and maintained.

In addition, a cable trunk 1344 may be formed above the water treatment module 134b. One or more cables used in the water treatment module 134b may be extended to the outside through the cable trunk 1344 in an aligned state. In this case, the area where the cable used in the water treatment module 134b passes through the deck can be minimized.

Although the embodiments of the present invention have been described above, those skilled in the art can add, change, delete, or add components within the scope not departing from the spirit of the present invention described in the claims. The present invention can be variously modified and changed by the like, and this will also be said to be included within the scope of the present invention.
