Description

Technology Field

[0001] The present invention relates to a technology for installing a building placed in a plant. Background Technology

[0002] Plants that process materials using various equipment include natural gas plants that perform the liquefaction of natural gas or the separation and recovery of liquid natural gas; petroleum refining plants that perform the distillation or desulfurization of crude oil or various intermediate fractions; chemical plants that produce petrochemical products, intermediate chemicals, polymers, etc.; pharmaceutical plants that manufacture medicines; waste treatment plants for low-level radioactive waste; and plant factories that produce plants such as vegetables. These plants are composed of a combination of multiple pieces of equipment.

[0003] Generally, in addition to the equipment that performs the processing of the target material, power-related equipment or control-related equipment is installed alongside the equipment constituting the plant.

[0004] These power-related equipment and control-related equipment may be grouped and arranged in separate buildings independent of the main equipment placement area of ​​the plant, for the sake of shortening the plant construction period or maintenance after construction (e.g., Patent Document 1). These buildings may be installed on a foundation provided on the ground of the site where the plant is constructed, or on a frame provided on said foundation, through supports that support the buildings.

[0005] When installing a building, the strength of the foundation and frame is designed to withstand wind pressure from strong winds or shaking associated with earthquakes. Additionally, a construction method is sometimes adopted in which modules with the building fixed to the frame are built at a remote factory and then transported and deployed to the plant construction site. In this case, it is necessary to design the strength of the frame while also taking into account the shaking of the building that occurs during transportation.

[0006] In implementing such strength design, if a structure is adopted that connects the building to the foundation or frame through rigid connections, the design must be carried out on the premise that moments are applied to the frame or foundation due to shaking. As a result, it becomes necessary to enlarge the foundation or construct the frame using larger steel materials, which becomes a factor in increasing the plant's construction costs.

[0007] On the other hand, while pin connections using bolts can keep the moment applied to the frame or foundation small, their fatigue strength against shaking during maritime transport is low, requiring a large number of bolts and consequently necessitating a massive base plate. Additionally, the building must be installed so that the bolt holes at the connection points with the foundation or frame align with the holes in the base plate, making installation difficult. There is also a concern that this method may increase the construction costs of the plant. Prior art literature

At this time, the support portion supporting one end of the upper surface stopper portion and the support portion supporting the other end are each shared between the two upper surface stopper portions.

With this configuration, the magnitude of the moment applied to the installation surface side due to the occurrence of building shaking is suppressed, thereby suppressing the enlargement of the foundation or frame constituting the plant and suppressing the increase in construction costs of the plant.

[0029] Hereinafter, as an example of a plant, an embodiment of installing a building using the installation mechanism (installation method) of the present disclosure will be described for an LNG plant (1) that produces liquefied natural gas.

[0030] FIG. 1 is a schematic side view of a part of an LNG plant (1). The LNG plant (1) is equipped with a number of devices for performing various treatments to produce LNG, such as separating liquid contained in gaseous natural gas (NG: Natural Gas), removing impurities such as mercury, moisture, and heavy matter, and then cooling and liquefying the NG.

[0031] In addition, the LNG plant (1) is equipped with auxiliary facilities such as an oil heater or boiler that heats a heat medium (e.g., hot oil or steam) used for various heating operations performed in each process, and a gas turbine generator or gas engine generator that supplies power consumed within the LNG plant (1). A number of devices are also installed in these auxiliary facilities.

[0032] A number of devices constituting the LNG plant (1) are grouped by type, for example, processing or auxiliary equipment, and installed within a plurality of frames (100). The frames (100) of this example are constructed as steel frame structures capable of arranging these devices in multiple layers in the vertical direction.

[0033] For example, in the center of FIG. 1, a processing unit (11) is arranged to perform one of the processes for producing LNG. In the processing unit (11), a static unit (101) that is not equipped with power equipment such as a tower tank or a heat exchanger, a dynamic unit (102) equipped with power equipment such as a pump, and a connecting pipe (not shown) that connects between each static unit (101) and synchronous unit (102) or between the synchronous unit (102) on the side of the pipe rack (12) described later.

[0034] In addition, in FIG. 1, a pipe rack (12) is arranged to the right of the processing unit (11). The pipe rack (12) is configured such that a plurality of pipes (103) through which fluid flows between each processing unit (11) are arranged relative to the frame (100).

[0035] In addition, on the upper surface of the pipe rack (12) shown in Fig. 1, a plurality of air-cooled heat exchangers (ACHE: Air-Cooled Heat Exchanger) (104) are arranged in a row to cool the fluid handled in a predetermined processing unit (11).

[0036] Among the equipment installed in the LNG plant (1), for power consuming equipment such as synchronous equipment (102) and power generators that consume power, power is supplied in a transformed state according to the rated voltage of each power consuming equipment.

[0037] Here, power supply equipment such as a substation that performs voltage conversion, a power supply control facility that performs power supply control to each power consuming device, and circuit breakers or disconnectors is installed in these power consuming devices. These power supply equipment is housed within a building (13) consisting of an outer structure partitioned from the surroundings. This building (13) is called a substation and is installed in parallel with the frame (100) in which the power consuming devices are housed.

[0038] Additionally, the equipment installed in the LNG plant (1) includes various control devices, such as a flow control valve for adjusting the flow rate of the fluid, a pressure control valve for adjusting the pressure inside the tower tank, a flow control valve for increasing or decreasing the flow rate of the heat transfer fluid or refrigerant to adjust the heat exchanger outlet temperature of the fluid to be controlled, and an opening / closing valve that performs opening and closing operations according to the liquid level inside the tower tank.

[0039] A controller is installed in conjunction with these controlled devices, and a control loop is established that outputs a control signal from the controller to the controlled devices based on the results of detecting the fluid flow rate, pressure, temperature, or liquid level by the detection unit, and performs operation control of each controlled device.

[0040] At this time, a control information output device called an FCS (Field Control Station) is provided. The control information output device outputs information related to the operation control of the device under control, such as flow rate setting values, pressure setting values, and temperature setting values ​​received from an operator or automatic control device, to a controller that controls the operation of the device under control, or outputs information such as the flow rate, pressure, temperature, or liquid level of the fluid detected by the detection unit to the central control room that performs overall control of the entire LNG plant (1). This control information output device is also housed within a building (13) consisting of an outer structure partitioned from the surroundings. This building (13) is called the device control room and is installed independently of the substation described earlier, and is installed in parallel with the frame (100) in which the device under control is housed.

[0041] In the example shown in FIG. 1, the processing unit (11), the frame (100) of the pipe rack (12), and the building (13), which is a substation or equipment control room, are provided on a concrete foundation not shown that is pre-installed on the site where the LNG plant (1) is to be constructed.

[0042] In this case, the building (13) can be installed on the installation surface (2) of the concrete foundation described above through a plurality of supports (131) installed to extend downward from the lower surface of the outer structure constituting the building (13).

[0043] In installing this building (13), the LNG plant (1) of this example does not use rigid joints and adopts an installation mechanism that installs a support (131) on the installation surface (2). Below, the detailed configuration of the installation mechanism will be explained with reference to FIGS. 2 to 5.

[0044] FIG. 2 is a partially broken perspective view showing the lower part of a support (131) of a building (13) installed on an installation surface (2) using the installation mechanism of the present example. FIG. 3 to 5 are exploded perspective views showing the sequence of installing the support (131) on an installation surface (2) using this installation mechanism.

[0045] As illustrated in FIG. 3, a base plate (132) made of steel material that is rectangular when viewed from a plane and has, for example, a flat bottom surface is installed at the bottom of the support (131). The base plate (132) is joined to the support (131), for example by welding. The base plate (132) constitutes part of the installation mechanism of the present example.

[0046] Meanwhile, on the upper surface of the installation surface (2), for example, a flat placement area (20) is set, and after placing a base plate (132) on this placement area (20), a building (13) is installed using an installation mechanism. At this time, the base plate (132) is not fixed to the installation surface (2) by welding or bolts.

[0047] As shown in FIG. 2, the installation mechanism further includes a side stopper part (41, 41a) provided at a position opposite with a gap between the sides of a base plate (132) placed in a placement area (20) of an installation surface (2), and a yoke (32), which is a top stopper part provided at a height position opposite with a gap between the top surface of the base plate (132).

[0048] As illustrated in FIG. 3, the side stopper portions (41, 41a) are members positioned corresponding to each of the four sides of the base plate (132) to surround the placement area (20) where the base plate (132) is placed. Each side stopper portion (41, 41a) is constructed, for example, by steel. In the example of the installation mechanism shown in FIG. 2, the two side stopper portions (41) positioned along the yoke (32) are constructed by members in the shape of a thick plate. Meanwhile, the stopper portion (41a) positioned between the support portion (31) described later and the base plate (132) is constructed by members in the shape of a short rod plate with dimensions along the direction intersecting the side of the base plate (132) (refer to the area shown by cutting out a part of the support portion (31) in FIG. 2).

[0049] Additionally, as shown in FIG. 2, a side stopper portion (41) with a common rear plate shape may be provided corresponding to all four sides of the base plate (132). In this case, a configuration can be exemplified in which a cutout is provided at the bottom of the support portion (31a) to avoid interference with the side stopper portion (41).

[0050] The placement positions of each side stopper part (41, 41a) are set to opposite positions with a gap of about a few mm to a few cm between them for each side when the base plate (132) is placed in the placement area (20).

[0051] In this state, by placing the base plate (132) in the placement area (20), the side stopper portions (41, 41a) can be positioned facing the side of the base plate (132) with a gap between them (process of positioning the side stopper portions (41, 41a)).

[0052] Each side stopper part (41, 41a) is fixed to the installation surface (2) around the installation area (20). There are no special limitations on the method of fixing the side stopper parts (41, 41a), and a fixing method suitable for the member constituting the installation surface (2) can be adopted. For example, if the installation surface (2) is made of concrete, the installation surface (2) with bolt holes and the side stopper parts (41, 41a) may be fastened together by bolts. Also, if the installation surface (2) is made of steel, the side stopper parts (41, 41a) may be attached to the installation surface (2) by pin joining.

[0053] As shown in FIG. 4, a thin, elongated spacer plate (42) is inserted into the gap between the opposing base plates (132) and each side stopper part (41, 41a) to fill the gap (process of inserting the spacer plate (42)). The spacer plate (42) serves to prevent misalignment of the support (131) (building (13)) in the direction along the installation surface (2). The spacer plate (42) is made of a metal material or a hard rubber material, and is fastened to the side wall of the base plate (132) using a bolt (421).

[0054] Additionally, as illustrated in FIGS. 2 and 3, a support member (31) that supports the yoke (32) is installed at a position opposite to each side stopper member (41a) in the shape of a rod plate. For example, the support member (31) is composed of a plate-shaped member having a side wall surface that extends parallel to the side of a rectangular base plate (132). These support members (31) are formed as a set and support both left and right ends of two yokes (32) arranged with the support member (131) in between. Each support member (31) is composed of, for example, steel.

[0055] In the installation mechanism of the present example, two yokes (32) are installed facing each other with a gap between them in two areas on the upper surface of a base plate (132) set with a support (131) in between. Corresponding to the arrangement of these yokes (32), a set of support members (31) is arranged with the two areas in between and supports the yokes (32) so as to extend along the upper surface of the base plate (132) (process of installing the yokes (32)).

[0056] These support members (31) are fixed to the installation surface (2) in the same way as the side stopper members (41, 41a). For example, if the installation surface (2) is made of concrete, a base plate for fixing may be provided at the lower end of the support member (31), and this base plate may be fastened to the installation surface (2) using bolts. Also, if the installation surface (2) is made of steel, the support member (31) may be attached to the installation surface (2) by a pin joint.

[0057] In the drawings, reference numeral 311 indicates a reinforcing member that reinforces the fixation of the support member (31) to the installation surface (2). When providing the reinforcing member (311), there are no special limitations on its shape or the number of installations. For example, as shown in FIG. 2, FIG. 3, etc., two plate-shaped reinforcing members (311) may be provided spaced apart from each other on the surface opposite to the support surface supporting the yoke (32), so that the cross-section of the entire support member (31) and the reinforcing member (311) forms a π shape according to the height direction of the support member (31). Furthermore, three or more reinforcing members (311) may be provided.

[0058] In addition, a structure may be adopted in which a plurality of reinforcing members (311) are provided between two plates arranged in parallel at a distance, and one plate of the structure is supported as a support member (31) to support the yoke (32).

[0059] As illustrated in FIG. 5, the yoke (32) is a plate-shaped member that is placed across the supporting surfaces of each set of support members (31) positioned opposite each other with the base plate (132) in between. The yoke (32) is made of, for example, steel. Each yoke (32) is installed at an opposing height position with a gap of several mm to several cm between them and the upper surface of the base plate (132). Each yoke (32) is joined to the supporting surface of the support member (31), for example by welding.

[0060] In addition, unlike the gap between the base plate (132) and the side stopper part (41, 41a) into which the previously described spacer plate (42) is inserted, no other member is inserted into the gap between the upper surface of the base plate (132) and the yoke (32).

[0061] In accordance with the order described above using FIGS. 3 to 5, the support (131) placed in the placement area (20) is installed on the installation surface (2) by the installation mechanism (Fig. 2). Then, the plurality of support (131) provided in the building (13) are each installed in the pre-set placement area (20) of the installation surface (2) using the aforementioned installation mechanism. Through this installation process, the building (13) is placed on a designated site of the LNG plant (1).

[0062] Let us assume that in a building (13) installed using the installation mechanism of the present example, shaking occurs due to strong winds or earthquakes. At this time, in the installation mechanism of the present example, side stopper parts (41, 41a) are arranged at the lower ends of a plurality of support posts (131) that support the building (13) from the bottom side, so as to face each side of a base plate (132) installed in the installation area (20). And, a spacer plate (42) is inserted into the gap between these base plates (132) and each side stopper part (41, 41a). With this configuration, even if the force of the lateral component of the shaking exceeds the influence of the building's own weight, the building (13) (each support post (131)) is prevented from shifting in the direction along the installation surface (2).

[0063] Additionally, if the force of the longitudinal component of the above shaking exceeds the self-weight of the building (13), the base plate (132) rises from the installation surface (2). At this time, in the installation mechanism of the present example, a yoke (32) is installed so as to face each other with a gap between them in two areas of the upper surface of the base plate (132) set with the support (131) in between. With this configuration, the base plate (132) can be suppressed so that it does not rise above a preset height defined by the gap with the yoke (32). By suppressing the height of this gap to a few mm to a few cm, the magnitude of the impact accompanying the base plate (132) falling after rising can be suppressed within a preset range, thereby preventing damage to the main body of the base plate (132) or the equipment housed inside it.

[0064] Meanwhile, the base plate (132) is merely placed on the installation surface (2) (placement area (20)) and is not directly joined to the installation surface (2). Therefore, compared to the case where the support (131) is connected to the installation surface (2) by a rigid connection, almost no moment is applied to the installation surface (2) when shaking occurs in the building (13). As a result, the increase in the size of the foundation can be suppressed, thereby suppressing the increase in the construction cost of the LNG plant (1).

[0065] FIG. 6 is a modified example of the installation mechanism shown in FIG. 2. In this example, a support part (31a) supporting one end of a yoke (32) and a support part (31a) supporting the other end are each separated between two yokes (32). In this case, since there is no interference with the support part (31a) compared to the side stopper part (41a) described in FIG. 2, a side stopper part (41) having the same rear plate shape as provided along the yoke (32) may be adopted.

[0066] Next, an embodiment in which a building (13) is installed on a module (1a) of an LNG plant (1), which is a transportable structure, will be described with reference to FIGS. 7 and 8.

[0067] In recent years, in the construction of an LNG plant (1), a method has been adopted in which the LNG plant (1) is divided into multiple modules (1a) and modules (1a) are constructed at a factory far from the construction site, with the main unit (101) or the synchronous unit (102) arranged on the frame (100). The constructed modules (1a) are each transported to the construction site and placed thereafter, and then connected to each other to form the LNG plant (1).

[0068] In the example described above, there are cases where a building (13) is installed in advance on the module (1a). In this case, the frame (100) of the module (1a) forms the installation surface (2) of the building (13). In this case, the installation mechanism of the building (13) is installed on the steel frame structure constituting the frame (100).

[0069] Here, for transporting modules (1a) weighing hundreds to thousands of tons, water transport using a transport ship (5) is employed. Meanwhile, during the water transport of the module (1a), the transport ship (5) shakes up and down due to the influence of waves, so a shaking force is always applied to the module (1a). At this time, if a gap is formed between the upper surface of the base plate (132) and the yoke (32) as in the installation mechanism described using FIG. 2, whenever a large shaking occurs, the base plate (132) rises and repeatedly collides with the yoke (32), which may damage the yoke (32).

[0070] Accordingly, during the transport period of the module (1a), a cushion plate (43) is inserted into the gap between the upper surface of the base plate (132) and the yoke (32), as shown in FIG. 8 (process of inserting the cushion plate (43)). The cushion plate (43) is made of, for example, wood or hard rubber material. By placing the cushion plate (43) between the yoke (32) and the base plate (132), the force repeatedly applied to the yoke (32) along with the shaking of the module (1a) is reduced, thereby preventing damage to the yoke (32).

[0071] After the water transport is completed and the module (1a) is placed on the construction site of the LNG plant (1) via subsequent land transport, the cushion plate (43) is removed to open the gap between the base plate (132) and the yoke (32) (process of removing the cushion plate (43)). After the placement of the module (1a) is completed, there is less risk of large shaking occurring in the building (13) on a daily basis compared to during the water transport period. Therefore, by opening the gap that was blocked using the cushion plate (43), it is possible to ensure that no force is applied from the base plate (132) to the yoke (32) unless large shaking occurs, such as the base plate (132) floating up.

[0072] Here, reference numeral 431 in FIG. 8 indicates a stopper to prevent the cushion plate (43) from slipping out of the gap between the base plate (132) and the yoke (32). For example, the stopper (431) is made of wood or hard rubber material and is fastened to the cushion plate (43) by a bolt. By using the stopper (431), the cushion plate (43) can be prevented from slipping out without fastening the cushion plate (43) to the base plate (132) by a bolt. For this reason, there is no need to provide a bolt hole in the main body of the base plate (132).

[0073] If bolt holes are formed in the base plate (132), there is a risk that water will accumulate in the bolt holes after the cushion plate (43) is removed, and corrosion will proceed. Therefore, by using a stopper (431) to prevent the cushion plate (43) from falling off without using bolts, corrosion of the base plate (132) caused by the formation of bolt holes can be prevented.

[0074] Although an embodiment in which the installation mechanism of the present disclosure is applied to a building (13) attached to an LNG plant (1) has been described above, the plant to which the installation mechanism can be applied is not limited to the LNG plant (1). For example, the installation mechanism of the present disclosure can also be applied to a building (13) attached to a plant that processes various materials (except for manufacturing plants for automobiles, machinery, electronic devices, semiconductor devices, etc.), such as a natural gas plant that separates and recovers liquid natural gas contained in natural gas, a petroleum refining plant that performs distillation or desulfurization of crude oil or various intermediate fractions, a chemical plant that produces petrochemical products, intermediate chemicals, polymers, etc., a pharmaceutical plant that manufactures pharmaceuticals or their intermediate products, a waste treatment plant that treats low-level radioactive waste, or a plant factory that produces vegetables, etc.

[0075] At this time, the equipment for processing the object to be processed installed in the plant or the equipment installed in the auxiliary facility is not limited to being placed in the frame (100), which is a frame structure, as in the LNG plant (1) exemplified in FIG. 1. For example, such equipment may be housed in the main building, which is an outer structure, and may be fixed using the installation mechanism of this example to a building (13) that is smaller than the main building and is installed alongside the main building.

[0076] In addition, regarding the building (13) that can be fixed using the installation mechanism of the present example, the types of equipment housed in the building (13) are not limited to the power supply equipment or control information output equipment already described. For example, the building (13) that houses equipment related to the processing of a target object, or some auxiliary equipment related to the supply of heat transfer fluids, electricity, etc., can also be fixed using the installation mechanism of the present example.
