Description

Technical Field

[0001] The present invention relates to the technical field of ship inspection, and in particular to a ship system inspection work package design method and system based on construction rules. Background Art

[0002] In the complex process of ship design and construction, multiple key links such as hull structure, ship piping, hull insulation and external outfitting have a vital impact on the safety, reliability and overall performance of the ship. However, the current traditional model of ship construction and inspection has many drawbacks, which seriously restricts the improvement of ship construction quality and efficiency.

[0003] First of all, the hull structure is the support and load-bearing body of the ship. The traditional mode of its construction and inspection process mainly relies on document-based design, that is, the inspection process is compiled and expressed in the form of documents. This mode requires operators to manually modify documents when the design changes, which is not only inefficient, but also prone to errors and omissions, resulting in poor consistency between the design and on-site production inspection. In addition, the two-dimensional drawing information relied on during the on-site inspection process is relatively abstract, which increases the difficulty for on-site personnel to understand the inspection process and affects communication efficiency. At the same time, the inspection data and structure are stored in paper form, which is neither convenient for preservation nor can it effectively support further quality analysis.

[0004] Secondly, as an important part of the ship, the construction and inspection of the ship piping system also face challenges from the traditional model. The problems in process design, modification, information transmission and data storage of the piping system inspection are similar to those in the hull structure and electrical inspection, which seriously affect the quality and efficiency of piping system construction.

[0005] Furthermore, as an important measure to protect the cabin environment and life safety of ships, the construction and inspection process of hull insulation is also restricted by traditional models. The processing, construction and inspection of insulation materials all rely on document-based design, resulting in poor consistency between design and on-site inspection, and difficulties in storing and analyzing inspection data.

[0006] Finally, as a key system that affects the safety of ship navigation, the inspection process of external outfitting also relies on traditional two-dimensional drawings and document modes. This mode has obvious deficiencies in information expression, transmission, storage and analysis, and it is difficult to meet the requirements of modern shipbuilding for high quality and high efficiency.

[0007] To sum up, the ship construction and inspection model in the existing technology has many drawbacks. In order to ensure the consistency between design and on-site production inspection, improve design efficiency, ensure that on-site construction personnel accurately understand the design intent, and improve inspection quality and efficiency, this application provides a ship system inspection work package design method and system based on construction rules. Summary of the invention

[0041] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0042] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and therefore the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0043] Ships are important tools for ocean transportation, and the safety and reliability of their structures are crucial to the navigation of ships. The hull structure, piping, insulation materials, and external outfitting are the main parts of a ship, and they occupy a core position in the shipbuilding process. However, the existing shipbuilding and inspection processes have some obvious limitations, which not only affect the efficiency of shipbuilding, but also pose a potential threat to the safety and reliability of ships.

[0044] Piping system construction and inspection: As an important part of a ship, the ship piping system is constructed and inspected in a document-based design mode. In this mode, design changes will cause process personnel to modify documents, which is inefficient and prone to errors. On-site inspections are based on paper documents, and the information abstraction of two-dimensional drawings will hinder on-site personnel's understanding and communication of inspection processes. Paper storage of inspection data and results is difficult to save and cannot support further analysis.

[0045] Hull structure inspection: The traditional hull structure inspection process mainly relies on the file-based design mode, and the process is compiled and expressed in the form of documents. In this mode, once the design changes, the process personnel need to modify the document manually, which is not only inefficient, but also prone to omissions and errors, resulting in poor consistency between the design and on-site production inspection. In addition, on-site self-inspection, mutual inspection, special inspection and shipowner inspection are all based on paper documents. The information in the two-dimensional drawings is abstract, which is not conducive to the understanding and communication of the inspection process by on-site personnel. The paper storage method of inspection data and results is also difficult to preserve for a long time, which is not conducive to further data analysis.

[0046] Outfitting inspection: Outfitting involves many key systems in shipbuilding, and its inspection process mainly relies on two-dimensional drawings and documents. In this mode, information expression is abstract, which may lead to differences in understanding and communication between on-site personnel. The expression and transmission of documents are also prone to omissions and errors. Paper documents are not conducive to the storage and query of inspection data and results.

[0047] Hull insulation construction and inspection: Ship insulation construction includes multiple links, such as inner plate rust removal, anti-rust painting, insulation material construction, etc. The existing inspection process is also inefficient and prone to errors, and paper documents are not conducive to the understanding and communication of on-site personnel, and the storage and analysis of inspection data and structures are also difficult.

[0048] In view of the above defects, the present application provides a ship system inspection work package design method and system based on construction rules, which are now described in detail through the following embodiments.

[0049] Embodiment 1

[0050] This embodiment provides a ship system inspection work package design method based on construction rules, such as Figure 1 As shown, the ship system is a piping system, and the design method includes the following steps:

[0051] S110. Inspection attribute definition: Based on the three-dimensional model of the piping system, the inspection phase, inspection items, inspection elements, inspection level, and inspection standard of the piping system are defined and associated with the three-dimensional model of the piping system in the form of attributes.

[0052] For example, taking the pipeline as the object and based on the pipeline 3D model, the pipeline system inspection attribute definition is completed in a visual and interactive way. The inspection attributes include but are not limited to inspection stage, inspection items, inspection elements, inspection level and inspection standard.

[0053] The specific definitions of inspection stages, inspection items, inspection elements, inspection levels and inspection standards are as follows:

[0054] Inspection phase definition:

[0055] The construction stage of the pipeline is defined by attribute definition. Different shipyards have different divisions of construction stages. The main stages should include: pipe segment production, segment installation, and overall segment installation. The above stages can be added, deleted, and modified according to the actual construction division rules of the shipyard. Each stage type needs to be defined in the inspection stage library in advance.

[0056] Inspection item definition:

[0057] The attribute definition method is used to define the inspection item name of the piping system, and the corresponding inspection item code is automatically generated. The code is used to support the identification and retrieval of the inspection items in the later stage. The main inspection items of the piping system include pipe bending inspection, weld inspection, non-destructive inspection, pipe strength test, pipe cleaning, etc. Each inspection item is named "weld inspection" and the inspection item number is automatically generated, such as 002-1206-343. The specific coding rules are defined by the shipyard itself. Among them, according to the name of the pipe section, the relevant inspection items can be automatically pushed for the process personnel to select.

[0058] Inspection element definition:

[0059] The inspection elements of the pipe system inspection items are defined by attribute definition, including but not limited to surface treatment, external dimensions of pipes after assembly, welding quality, system installation integrity, installation accuracy, etc. Taking the inspection of a pipe bend as an example, the inspection elements are mainly external dimensions, including bending angle, bending radius, etc. Among them, according to the names of pipe system components and the defined inspection items, relevant inspection elements can be automatically pushed for selection by process personnel.

[0060] Inspection level definition:

[0061] Different inspection items require different management and control methods, that is, different inspectors are required to participate. The inspection level of the inspection items is defined by attribute definition. The definition of the inspection level needs to refer to the hull construction requirements and the actual situation of the shipyard. For example, there are the following types: Level I, which requires self-inspection by on-site operators and inspection by team leaders; Level II, which requires self-inspection by on-site operators, inspection by team leaders, and special inspection by the quality management department; Level III, which requires self-inspection by on-site operators, inspection by team leaders, special inspection by the quality management department, and inspection by the shipowner. Among them, according to the name of the piping system and the defined inspection items and inspection elements, the inspection level can be automatically pushed for the process personnel to choose.

[0062] Inspection standard definition:

[0063] The attribute definition method is used to define the inspection standards that need to be referenced for the inspection items. For example, the pipe manufacturing inspection needs to refer to the "Basic Requirements and Tolerance Requirements for Pipe Manufacturing", and the pipe installation needs to refer to the "Technical Requirements for System Pipe Manufacturing, Installation, Cleaning and Testing". Among them, according to the defined inspection items and inspection elements, the relevant inspection standards can be automatically pushed for process personnel to choose.

[0064] S120. Verify the definition of geometric elements: Based on the three-dimensional model of the piping system, the definition of geometric elements is verified by three-dimensional annotation.

[0065] Based on the three-dimensional model of the piping system, the definition of inspection geometric elements is realized by three-dimensional annotation to provide guidance for subsequent on-site inspection and construction. The inspection geometric elements that need to be defined include three types: reference elements, measured elements and measurement auxiliary information.

[0066] Among them, the reference element refers to the element used to determine the direction and / or position of the measured element;

[0067] The elements to be tested are those for which shape and / or position tolerances are given in the inspection atlas;

[0068] Measurement auxiliary information refers to the supplement to the reference elements and measured elements in the inspection atlas.

[0069] The specific definitions of reference elements, measured elements and measurement auxiliary information are as follows:

[0070] Datum feature definition:

[0071] Based on the 3D model of the piping system, the definition of inspection benchmark elements is completed, including benchmark points, benchmark lines, and benchmark planes;

[0072] Reference point: refers to the point used as a reference to determine the shape and / or position tolerance of other points, lines, surfaces, etc., generally the center of a sphere or a circle;

[0073] Datum line: refers to the point used as a reference to determine the shape and / or position tolerance of other points, lines, surfaces, etc., usually a straight line or a curve;

[0074] Reference surface: refers to the surface used as a reference to determine the shape and / or position tolerances of other points, lines, surfaces, etc., generally a plane or a curved surface.

[0075] Definition of measured elements:

[0076] Based on the three-dimensional model of the piping system, the definition of the test elements is completed, including points, lines and surfaces.

[0077] Measurement auxiliary information definition:

[0078] Based on the three-dimensional model of the piping system, the definition of auxiliary measurement information is completed, including the drawing of auxiliary measurement points, auxiliary lines, auxiliary surfaces, and the marking of dimensional tolerances, form and position tolerances, auxiliary texts, symbols and other information. The auxiliary information is a supplement to the reference elements and measured elements to facilitate on-site inspection personnel to understand the inspection process.

[0079] S130. Definition of inspection accuracy requirements: Based on the three-dimensional model of the piping system, the definition of inspection accuracy requirements is implemented in a three-dimensional annotation manner.

[0080] Inspection accuracy requirements must be correlated with the elements being measured.

[0081] Based on the 3D model of the piping system, the inspection accuracy requirements are defined in a 3D annotation manner. Each accuracy requirement must be associated with the element being tested. The inspection accuracy requirements include the following three aspects: dimensional accuracy, shape and position accuracy, and surface accuracy (surface roughness, waviness). Based on the defined inspection items and inspection elements, the relevant inspection accuracy requirements can be automatically pushed for selection by process personnel.

[0082] S140. Definition of inspection implementation requirements: Based on the three-dimensional model of the piping system, define the inspection implementation requirements for the piping system.

[0083] The inspection implementation requirements are defined using attribute definition method, including but not limited to personnel requirements, environment requirements, tool requirements, inspection procedures, operation requirements, etc.

[0084] The specific definitions of personnel requirements, environmental requirements, tool requirements, inspection procedures, and operation requirements are as follows:

[0085] Personnel requirements:

[0086] The attribute definition method is used to define the personnel requirements for piping system inspection work, including but not limited to the number of personnel, personnel qualification requirements, etc.

[0087] Environmental requirements:

[0088] The attribute definition method is used to define the environmental requirements for piping system inspection work, including but not limited to temperature, humidity, and wind speed.

[0089] Tool requirements:

[0091] Inspection process:

[0092] The inspection process of the piping system inspection work, that is, the specific operation steps of the inspection work, is defined by using attribute definition.

[0093] Operation requirements:

[0094] The attribute definition method is used to define the operational requirements for piping system inspection work, that is, the operational matters that need to be paid attention to during the inspection.

[0095] Among them, according to the defined inspection items and inspection elements, relevant personnel requirements, environmental requirements, tool requirements, inspection procedures, operation requirements and other process personnel selections can be automatically pushed.

[0096] S150. Inspection view definition: for the inspection process, an inspection view is constructed based on the three-dimensional model of the pipe system.

[0097] Based on the 3D model of the piping system, combined with models of tooling and tools, an inspection view is constructed to visualize the on-site layout of the piping system inspection, inspection and measurement methods, measurement objects, measurement locations, etc., and to describe the relevant information of the inspection process in text.

[0098] S160, Inspection form definition: Extract the inspection attributes, inspection geometric elements, inspection accuracy requirements, inspection implementation requirements and inspection view information of the piping system and fill them into the general inspection template to automatically generate a special electronic inspection form for the piping system.

[0099] According to the paper inspection forms of different piping systems, a general inspection template for piping systems is constructed for each stage of piping system construction. Based on the above-mentioned information defined by the piping system, relevant data is automatically extracted from the inspection attributes, inspection geometric elements, inspection accuracy requirements, inspection implementation requirements and inspection view information of the piping system and filled into the general inspection template, and a special electronic inspection form for the piping system is automatically generated. On-site personnel feedback the inspection data and results in the electronic form to achieve structured storage of inspection data and results.

[0100] S170, Generation of inspection work package: The inspection attributes, inspection geometric elements, inspection accuracy requirements, inspection implementation requirements, inspection views, and inspection forms of the piping system are structured and organized to form an inspection work package.

[0101] The inspection attributes, inspection geometric elements, inspection accuracy requirements, inspection implementation requirements, inspection views, and inspection forms of the piping system are structured and output in a common or customized format. On-site personnel open the inspection work package on a fixed or mobile terminal and complete the inspection work with reference to the inspection work package.

Inspection attribute definition: Based on the three-dimensional model of external outfitting, the inspection phase, inspection items, inspection elements, inspection level and inspection standard of the external outfitting are defined and associated with the three-dimensional model of the external outfitting in the form of attributes.

[0158] For example, taking the exterior outfitting as the object and based on the exterior outfitting 3D model, the inspection attribute definition of the exterior outfitting 3D model is completed in a visual and interactive way. The inspection attributes include but are not limited to inspection area, stage, inspection item, inspection element, inspection level and inspection standard.

[0159] The specific definitions of inspection areas, stages, inspection items, inspection elements, inspection levels and inspection standards are as follows:

[0160] Inspection area and stage definition:

[0161] The attribute definition method is adopted to define the installation area and stage of the external outfitting 3D model. Different shipyards have different divisions of the installation areas and stages of the external outfitting 3D model. The above-mentioned areas and stages can be added or deleted according to the actual installation division rules of the shipyard; for the 3D models of the key systems, equipment, iron and steel parts of the external outfitting, multi-layer inspection information can be defined for each 3D model according to the construction division rules.

[0162] Inspection item definition:

[0163] The attribute definition method is adopted to define the inspection items required after the installation of the external outfitting three-dimensional model, and define the corresponding inspection item names in the above three-dimensional model; at the same time, a unique inspection item code is automatically generated according to the inspection item, and the inspection item code can support the identification and retrieval of the inspection item in the later stage. Taking the double plate inspection item of a key area stage of external outfitting as an example, the inspection item name is defined as "installation integrity inspection", and the inspection item code is automatically generated, such as 002P-235-001. The specific inspection item coding rules are defined by the shipyard.

[0164] External outfitting can sort out all inspection items according to construction inspection requirements and define them in the inspection item library in advance.

[0171] The external outfitting can define the corresponding inspection level according to the inspection items in advance, and define the corresponding information in the inspection level library in advance. Later, the relevant inspection level can be automatically pushed according to the inspection items or interactively selected and defined by process personnel.
