Description

[0001] The present invention relates to a method for managing ship and marine structure materials,

The present invention relates to a method of managing materials for ships and offshore structures. More specifically, by computerizing and managing the residues generated by the cutting process of raw materials in the process of manufacturing and drying ships and offshore structures, it is possible to minimize process delays by making quick decisions on the use of raw materials and residues according to the drying schedule, By increasing the recycling rate of the residue, it is possible to reduce the disposal throughput of the residue, reduce the amount of raw materials, and in particular, reduce the cost and time required for processing the residue, And to a method of managing materials for ships and offshore structures.

Recently, due to the development of maritime trade and the development of marine resources, the demand for ships and offshore structures is rapidly increasing, and the demand for materials for building ships is also increasing.

Generally, in the ship drying process, various raw materials such as steel plates and H beams and angles are used to form hulls and various structures. Such raw materials are manufactured and circulated in the form of standard products having a certain size It is used to make specific parts or hull structure for ships or offshore structures by cutting the raw materials according to the size of raw materials at the time of manufacturing the ship and then joining the cut raw materials by welding or the like.

In the case of manufacturing such specific parts or hull structure, the use of the external workshop in the shipbuilding in a single shipyard has increased dramatically, and the amount of movement of the materials including the materials has also increased as the amount of the dry matter has increased.

Cutting the standardized raw materials in each workshop into a member having the required specific shape and size of the ship or offshore structure inevitably leaves a residue from the raw material. Since a large number of raw materials are used in the process of drying and fabricating a ship or an offshore structure, the amount of residue remaining after the cutting of the raw material is increased by an increase in the amount of dry matter.

These residues can be reused in the manufacturing and drying process, recovered as waste or discarded, or supplied to the raw material producer for recycling when the drying schedule and the material materials are the same. Since additional costs arise in the disposal or recycling process, It is economically inefficient and very inefficient in terms of overall process efficiency.

Particularly, when the shipyard does not manage such residues, a considerable amount of residues are generated, and it takes a great deal of time and money to process the residues, and there is also a problem that a large number of residents are required to handle the residues. In addition, even if the remnants are managed, the operator can not classify and record them by hand according to the types of remnants, so that accurate and smooth remnant management can not be achieved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a flowchart illustrating an operation process of a ship and an offshore structure material management method according to an exemplary embodiment of the present invention. FIG. 2 and FIG. 3 are flowcharts of operations of a ship and an offshore structure material management FIG. 4 is a view schematically showing a state where residues are deposited on a stocker through a ship and an offshore structure material management method according to an embodiment of the present invention. Referring to FIG.

The ship and offshore structure material management method according to an embodiment of the present invention includes steps S1, S2, S3, S5, S5, S6), a receivable-of-receivable derivation step (S7), and a destruction accounting step (S9).

In the ordering stage (S1), the pre-nesting process is used to determine the amount of raw materials and some residues to be used in the detailed design stage before the production, and the materials required for the construction and manufacture of ships and offshore structures are firmly ordered.

In the raw material receiving and registering step (S2), the raw material materials ordered through the ordering step (S1) are sequentially received according to the process plan, and the received raw materials are registered in a separate database.

The residue calculation step (S3) is performed in such a manner that residues arising from the raw materials are calculated according to the amount of material used in the design process of the ship or offshore structure. For example, a design drawing is created to cut a member of a certain size from a raw material. At this time, a design drawing is created in a form in which the remnants from the raw material can be minimized by using a design program such as a nesting program, Calculate the residuals expected from the raw materials according to the design drawings.

The remnant registration step (S5) is performed in such a manner that the remnants generated for each block production work site are compared with the planned drawings, registered in the designated stocking place, and registered in the remnant management program. That is, in the cutting processing line, the raw material is actually cut according to the design drawing. The actual generated residues are compared with the planned drawings through the cutting processing step, and the result is stored in a separate designated storage space. At the same time, And registers the corresponding remnant.

In addition, in the residue registration step (S5), the residue generated after the cutting of the raw material is configured to move to the residual stockyard of the designated work site according to the next requirement plan.

After performing the residue registration step (S5), a separate comparison confirmation step may be performed. The comparison confirmation step S5 is performed in such a manner that the residues calculated in the residing calculation step S2 and the residues registered in the residue registration step S4 are compared with each other. Check whether the generated residues are identical. If the two residues are different from each other, it is desirable to go through the residue registration step (S4) again after finding the cause.

The necessary residue deriving step (S6) is performed in a manner of deriving a necessary necessary remnant list in comparison with the drying schedule for the remnants necessary for each block production work site.

The step of deriving the receivable residue (S7) is performed in such a manner that the state of the receivable residues can be grasped according to the block production schedule and a list of receivable receipts can be derived before the production. In addition, in the step of deriving the receivable residue (S7), according to the work schedule of the ship and the offshore structure, it is possible to check the cost based on the material available to be carried and the materials that can be sorted and moved by the minimum moving distance A list of receivable remnants that can be minimized is derived.

The destruction settlement step S9 is performed in such a manner that the unused remnants and the lost remnants are destroyed and settled.

In this case, the ordering step S1 is preferably performed in consideration of the remnants registered in the remnant management program through such a process. In other words, it is desirable to consider the residues registered in the residue management program in the process of ordering the raw materials. For example, it is desirable to minimize the ordering and the receipt of the raw materials as much as possible when the residue can be used instead of the raw materials. This can maximize the recycling of the residues and reduce the ordering and receipt of additional materials, thereby preventing cost reduction and waste of resources, and improving the process efficiency.

Meanwhile, in addition to this process, the ship and marine structure material management method according to an embodiment of the present invention further includes an identification sign display step (S4) of displaying an identification code in the remnant according to the kind of remnants actually generated from the raw materials of the block production worksite And the like. At this time, the remnant registration step (S5) is performed for the remnant marked with the identification code through the identification code display step (S4). That is, when a remnant is generated from the raw material, an identification code is displayed in the remnant according to the type of remnant, the remnant is placed in the stocking place, and the remnant is registered in the remnant management program according to the identification code.

At this time, the remnant is associated with the material number of the material database and the remnant number is derived, and the identification number can be displayed according to the remnant number. Accordingly, the remnants are verified in real time through the identification code to generate and delete remnants, and are managed so that the history applied to the ship and offshore structures can be confirmed.

On the other hand, the identification code may be displayed in a symbolized form of a plurality of pieces of information on the remnants, and may be formed in a barcode shape capable of displaying such information. According to the identification code of the barcode type, the remnant registration step (S5) can be performed by recognizing the identification code in the form of a barcode through a separate barcode recognizer and registering the identification code in the remnant management program.

In addition, the method of managing a ship and an offshore structure according to an embodiment of the present invention may further include a step of recycling (S8) a step of using the remnants deposited in the stocking site in the process of manufacturing and drying the ship and the offshore structure. At this time, it is preferable that the remnant calculation step (S3), the identification code display step (S4), and the remnant registration step (S5) are performed also for the re-occurring remnants from the recycled remnants. Particularly, in the remnant registration step (S5), when the remnant deposited in the stockyard is dispatched for recycling, it is preferable to perform the process of inputting the remnant dispensing information to the remnant management program.

More specifically, when the raw material 10 is received, a design drawing for cutting the raw material 10 is prepared so as to minimize the remnants in the designing process, and accordingly, as shown in FIGS. 2 and 3 (a) When the specific member 11 is cut from the raw material 10 according to the design drawing, the remaining portion remains in the form of the remnant 12.

Thereafter, as shown in FIG. 2 and FIG. 3 (b), the identification sign display step S4 is performed in such a manner that the identification code M is displayed for the actually generated remnants 12. [ The identification code M may be formed in the form of a barcode sticker as described above and may be displayed by an operator in such a manner that it is attached to the remnant 12. [ Thereafter, in the remnant registration step (S5), the barcode is recognized by the barcode recognizer so that the remnant 12 can be automatically registered in the remnant management program.

At this time, the identification code M can be displayed in a symbolized form of a plurality of pieces of information on the remnants 12. For example, the type of the remnants (section steel, steel plate, steel pipe, etc.), material, thickness, Numbers and the like may be displayed as alphanumeric characters.

In the remnant registration step S5, the remnant 12 is registered in the remnant management program, and the remnant material 12 is placed in the stocker 20. The stocker 20 is formed so as to be able to be stacked according to the type of the remnant 12 do. It is preferable that the respective residues 12 are formed so as to be spaced apart from each other so that the identification mark M indicated on each of the residues 12 may be exposed to the outside in a state where a plurality of the residues 12 are deposited. The operator can easily identify and classify the remnant 12 through the identification code M of the remnant 12 in the state where the remnant 12 is placed.

4, a plurality of separation guide bars 21 are formed so that each of the remaining members 12 can be individually stacked, (12) may be separately mounted. At this time, the separated remainders 12 are arranged so as to be spaced apart from each other by the separating guide bar 21, so that the identification mark M displayed on each remainder 12 can be easily identified.

In the comparative confirmation step, the residues 12 registered in the residue registration step S4 and the residues 12 calculated in the residue calculation step S2 can be compared with each other, and the residue registration can be modified according to the comparison result.

Meanwhile, in the recycling step S8, the residues 12 deposited on the stocker 20 are used again in the ship drying process. For example, as shown in FIGS. 2 and 3 (b) ) Can be recycled and the specific member (11) can be cut therefrom. For example, in the case of the specific member 11 having a relatively small size, the remnant 12 deposited on the stocking station 20 can be recycled and used. In this case, it should be judged whether or not the remnants 12 can be recycled in the designing process. In a specific situation, the remnants 12 may be directly recycled in the cutting process line irrespective of whether or not they are judged during the designing process.

When the remnants 12 are recycled again through the recycling step S8, the remainder of the remainder 12 where the specific member 11 is cut is left as the remainder 12 '. That is, as shown in FIG. 2 and FIG. 3 (c), another type of residue 12 is generated after the recycling step. Since the shape of the remnant 12 is changed, information on the remnant 12 should be changed. That is, the identification code M displayed on the remnant 12 should be changed to another type of identification code M 'so that the remnant 12 information of the changed type can be displayed. In addition, in the remnant registration step (S5), the remnant (12) with the changed information should be newly registered in the remnant management program.

Thereafter, the remnant can be used again in the same manner, and the remaining remnant can be utilized without disposal of the remnant by continuous utilization of the remnant, and similarly, another type of identification code should be displayed for the remnant after the re- Through this, the remnant can be continuously tracked from generation to extinction.

On the other hand, when the remnants 12 deposited on the stocking area 20 are recycled, the remnants 12 must be dispensed from the stocking area 20. In the remnant registration step S5, Can be performed. That is, in the remnant registration step (S5), both the registration of the remnants and the dispensation information are input to the remnant management program, thereby enabling more accurate remnant management.

The remnant management method described above can be applied not only to the remnants generated in the cutting line inside the shipyard but also to the remnants generated in the cutting line outside the shipyard. That is, in case of special situation inside the shipyard, or in case of specific blocks and parts of the ship, it is manufactured in a separate production line outside the shipyard and is put into the shipyard. In this case, it can be managed through the same residual management method, And the like can be managed at the same time in such a manner that the remnants generated during the manufacturing process at the time of the finished parts are received at the same time or the remnants are periodically put on the parts.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
