Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. It is to be understood, however, that the spirit of the invention is not limited to the embodiments shown and that those skilled in the art, upon reading and understanding the spirit of the invention, may easily suggest other embodiments within the scope of the same concept.

FIG. 1 is a block diagram showing a schematic configuration of a system for checking pipeline interference and installation order according to the present invention. FIG. 2 is a block diagram of a piping material coordinate information interlocking module according to the present invention, A diagram for explaining the process of loading data is shown.

Referring to these drawings, the system for checking the interference of marine plant piping material and checking the installation order of the marine plant piping material according to the present invention checks the interference between parts based on the production drawings (SPOOL) of a large number of parts constituting the offshore plant piping, It provides an optimal installation process.

To this end, the present invention provides a piping material interference information check interlocking module (100) for loading piping material information, a piping material interference check check module (200) for checking interference between respective parts using the piping material information loaded and forming an interference matrix, A vertical relationship analysis module 300, and a piping material installation order determination module 400 for determining an optimized installation sequence by synthesizing the interference matrix.

In detail, the piping material coordinate information interworking module 100 loads information including a pipe, a length and a weight based on information of a production drawing (SPOOL), and the loaded result can be confirmed through an execution screen as shown in FIG. 2 . The information loaded by the piping material coordinate information interworking module 100 can be expressed as a line segment based on the coordinates of the start and end points of each part.

The piping material interference check check module 200 checks whether or not the piping material is interfered with by using the information represented by the line segments as described above.

FIG. 3 is a block diagram showing a main configuration of a piping material interference check check module, which is a main constituent of the present invention. FIG. 4 is a block diagram of a piping material interference check check module according to the present invention. FIG. 5 is a view showing a state in which crossing is checked by a piping material interference check check module which is a main component of the present invention.

Referring to these drawings, the piping material interference check check module 200 confirms whether the parts cross each other on a plane in order to determine whether the parts intersect based on the loaded information.

Referring to FIGS. 4 and 5, in the piping material interference check check module 200, each line segment created based on the coordinate values interlocked with the coordinate values of the piping material is vertically oriented on the XY plane, Identify the intersection.

For this, the piping material interference check check module 200 includes a plane generator 220 for generating a virtual XY plane having a normal vector in which the installation direction of the piping material is set, and an XY plane generated by the plane generator 220, An intersection confirmation unit 260 for confirming whether or not pipelines orthogonally projected by the coordinate orthogonal projection unit 240 intersect in the XY plane, and an intersection confirmation unit 260 for confirming And an output unit 280 for outputting the generated interference generation piping.

That is, the piping material interference check check module 200 checks whether the interference is two-dimensional or not, and includes the following equations.

[Equation]

CCW (P3, P4, P2) <0 & CCW (P1, P2, P3)

That is, the intersection check unit 260 checks whether the two line segments intersect with each other through the equation. When the intersection is confirmed, the corresponding part or pipe material is output through the output unit 280.

On the other hand, the piping material output as described above is checked for interference in the three-dimensional space by the piping material top-bottom relationship analysis module 300.

In detail, the piping material top-bottom relationship analysis module 300 calculates a straight line distance from the contact point of the piping material that has confirmed interference occurrence through the output unit 280 to a plane having the installation direction as a normal vector, The piping material to be installed in the preceding stage is determined and an interference matrix is generated.

4 and 5, the piping material top-bottom relationship analysis module 300 calculates z-axis coordinate values by substituting the linear equations of P1 and P2 and the linear equations of P3 and P4.

In this case, if the z-axis coordinate value of the straight line of P1 and P2 is z1 and the z-axis coordinate value of the straight line of P3 and P4 is z2, then "1" if the value of z1 is larger than the value of z2, "0" . The above-mentioned substitution is performed in order to realize disassembly from a small-sized piping material because interference due to a piping material having a large z-axis coordinate value occurs when the interference matrix is implemented based on disassembly order.

Meanwhile, if the intersection between the parts or piping materials is confirmed by the piping material interference check check module 200 and the piping material vertical relation analysis module 300 as described above, it is represented by an interference matrix.

In this case, the generated interference matrix is represented only by "0" and "1" indicating interference, and the direction of orthogonal projection is the -z axis direction. However, since the actual installation direction is mostly from the upper side to the lower side, the matrix is transposed to obtain the matrix in the + z-axis direction.

When the interference matrix is generated as described above, the piping material installation order determination module 400 determines the position, weight, position, size, weight, and size of the piping material in consideration of the position, size, and weight of the piping material. The Analytic Hierarchy Process (AHP) is performed through a pair comparison, and weights are assigned according to relative importance to determine the optimal installation order.

In detail, in order to prioritize the piping material installation order, the present invention determines the weight to be given by selecting a position, a weight, and a size as elements of the analytical layering process.

To this end, the present invention is applied to a large number of practitioners, and an average of the scores of the two comparisons is obtained. The obtained averages are used as upper triangular matrices of the square matrices, and eigenvectors of the matrices are obtained to determine weights.

In the embodiment of the present invention, it is confirmed that the weights are given in order of Posion, Weight, and Size by combining opinions of practitioners who install piping materials using Table 1 as below, Weights of 0.5, 0.3 and 0.2 were derived, respectively.

Value Level of importance One Equally important 3 Slightly more important 5 Strongly more important 7 Very strongly more important 9 Extremely more important

In addition, ranking is given to each element in the installation priority, and each element is as follows.

First of all, in the case of position, it is the first thing to be considered at the time of installation, and the piping material at the time of design is classified according to the type and position of the structure.

That is, due to the nature of the topside structure of the offshore plant, the bottom part is positioned facing upward, and the piping material is installed first. Then, the turnover method is used to install the above part. In this invention, the position of the piping material is above And Below, so that the ranking of the bottom part is set low so that it can be installed first.

On the other hand, in the case of the weight, since the heavy parts have a limitation on the operation on the deck, the heavy equipment is set to be lower in the initial loading so that it can be installed first.

In the case of a size, the larger the piping material, the wider the range of installation space is occupied, so that the ranking of the large piping material is set to be low so that it can be installed first.

The order of installation of the final piping material is determined by multiplying the ranking by the physical quantity of each piping material, that is, the position (Posion), the weight and the size (Size) to obtain a total score, The installation priority is determined in that order.

Hereinafter, a method of checking the interference of the offshore plant piping material and confirming the installation order will be described using the above-described configuration of the offshore plant piping interference check and installation order confirmation system.

FIG. 6 is a flow chart showing a method of checking the interference of the offshore plant piping material and confirming the installation order according to the present invention, and FIGS. 7 to 10 are views showing a process of determining a piping material installation sequence according to the present invention .

Referring to these figures, in the present invention, step (S100) of loading coordinate information according to installation position and work unit of piping material and linking piping material coordinate information is performed.

The step S100 includes loading the information of the production drawing (SPOOL) using the piping material coordinate information interworking module 100 as described above, and displaying the coordinates as a line segment using the loaded information.

When the step S100 is completed, a step S200 of performing orthogonal projection of the coordinates of the piping material loaded in the virtual XY plane having the installation direction of the piping material as a normal vector is performed.

In step S200, the coordinates of the piping material can be displayed on a two-dimensional plane using the plane generator 220 and the coordinate orthorhombarder 240 of the piping material interference check check module 200.

When orthogonal projection is completed through step S200, a step S300 of determining whether orthogonal piping material coordinates intersect the XY plane is performed.

If interference is confirmed in step S300, a straight line distance from the contact point of the piping material to the plane having the installation direction as a normal vector is calculated to analyze the vertical relationship (S400).

That is, the intersecting piping material through the step S300 is additionally checked for interference in the space through the step S400.

Then, in step S300 and step 4300, a piping material to be installed ahead of the piping materials where interference occurs is determined and a decomposition priority order through the interference matrix is generated in step S500.

More specifically, in step S500, a process of marking a '1' when interference is generated through the steps S300 and S400 and a matrix of '0' when interference does not occur S510) is performed.

In step S520, an index having all row values of '0' in the matrix generated in step S510 is performed. In step S520, the part identified in step S520 is recorded, and ' 1 &quot; is added to determine the decomposition order (S530).

If the decomposition order is determined as described above, a process of removing the ordered components on the matrix (S540) is performed, and a process of reconstructing the matrix using the remaining components after the process S540 (S550) The generation of the interference matrix is completed by repeating the process from step S520 to step S550 in the matrix reconstructed by the step S560.

That is, in the generated matrix, as shown in FIG. 8, the rows 2, 3 and 7 are all identified as "0", and after adding "1" to each row, the matrix is removed and then the matrix is reconstructed.

Then, after confirming the first and fourth rows in which the values of all the rows are all "0", add "1" to each row, and then remove the row. The above process is repeated to remove all 8, The determination of ranking is completed.

In step S600, an installation priority is generated in a reverse order of the decomposition priority according to the interference matrix, and a weight is assigned to the generated installation priority to determine an optimized installation order.

That is, in step S600, as the reverse order of decomposition is the same as the installation order, the installation priority is determined in the reverse order of the decomposition priority according to the result of the step S500, and the determined installation priority is weighted Check the installation sequence.

The weight is derived by performing an Analytic Hierarchy Process (AHP) using a pairwise comparison using Position, Weight, and Size as described above. Then, the derived weight is multiplied by the physical ranking of each part to check the total score, and the optimized installation order is confirmed based on the confirmed total score.

11 is a view showing an embodiment of a piping material installation virtual simulation using a sequence defined by a marine plant piping material interference check and installation order confirmation system according to the present invention.

Referring to the drawings, in the present invention, the weights are given in the order of the position of the piping material, the weight of the piping material, and the size of the piping material, as described above, and the installation priority is determined in descending order of the total score obtained by multiplying the physical ranking by the weight Therefore, it was confirmed that installation priority is higher than that of relatively large and heavy parts.

According to the present invention, since the optimized installation priority is provided considering the physical quantity of the components and the interference between the components as described above, it is possible to provide a more efficient installation when the installation process is performed according to the installation priority determined at the actual installation of the piping material An operation can be performed.
