Description

Technical Field

[0001] This invention relates to the field of digital technology for offshore oil engineering, and in particular to a standard system and platform system for digital delivery throughout the entire lifecycle of offshore oil engineering. Background Technology

[0002] With the increasing demand for offshore oil engineering and the advancement of technology, digital delivery has become a key means to improve project efficiency and quality. However, in the implementation of digital delivery in offshore oil engineering, current practices mainly refer to relevant international industry standards, such as ISO 15926, CFIHOS, Q / SY01015-2017, and GB / T 51296-2018. But these standards all have limitations in fully adapting to the EPC (Engineering, Procurement, and Construction) delivery of offshore oil engineering projects.

[0003] ISO 15926, or Industrial Automation Systems and Integration, integrates lifecycle data from processing plants, including oil and gas production facilities. It features object-oriented programming, semantics, ontology, and markup languages, and is supported by a complete theoretical framework. The data models it defines are suitable for the entire lifecycle data integration of process plants. However, it also suffers from excessive freedom and complexity, such as being overly IT-oriented, lacking defined attribute ranges, and being difficult to implement in practice. This standard focuses on IT and digital delivery theory support and is not suitable as a digital delivery standard for offshore oil and gas engineering.

[0004] CFIHOS, short for Capital Facilities Information Transfer Specification, is an application practice of ISO 15926. It provides a practical standardized specification for information transfer in the process and energy industries. It has clearer transfer recommendations and more specific implementation requirements and constraints. However, its implementation requirements and constraints differ significantly from the situation of domestic offshore oil engineering business. This standard can be used as a reference for the application of digital delivery standards in offshore oil engineering.

[0005] Q / SY01015-2017, the Specification for Digital Transfer of Information for Oil and Gas Field Surface Construction Projects, is a corporate standard of China National Petroleum Corporation (CNPC) and is mainly applicable to CNPC's core business scope. However, this standard does not include any content related to offshore oil engineering. GB / T51296-2018, the Standard for Digital Delivery of Petrochemical Engineering, emphasizes the use of digital means for delivery, including but not limited to data, documents, 3D models, delivery methods, delivery strategies, and delivery platforms. However, it differs significantly from the actual situation of domestic offshore oil engineering operations and can provide an important reference for the digital delivery standards of offshore oil engineering.

[0006] Traditional engineering delivery methods rely primarily on manual processes and paper documents for data and information transfer. In large and complex offshore oil engineering projects, this often leads to untimely information delivery, data errors, and duplication of work, resulting in project delays and cost overruns. Furthermore, traditional methods lack flexibility in resource allocation and risk management.

[0007] Offshore oil engineering, as a multi-disciplinary, long-term, and high-value industry, faces significant challenges due to the complexity and integration of its technologies. Digital delivery requires the effective integration of data from multiple phases, including design, procurement, and construction. This necessitates not only sophisticated technical support for processing and analyzing massive amounts of data but also seamless interoperability between systems to ensure data consistency. However, most existing engineering data systems are often siloed, making cross-system data integration particularly difficult and increasing the risk of data errors and redundancy.

[0008] Furthermore, the digital delivery of offshore oil engineering projects faces the challenge of insufficient industry standards and regulations. While digital technologies are developing rapidly, related industry standards and regulations are lagging behind, leading to regulatory uncertainty and compliance risks during implementation. The lack of unified standards also makes it difficult to effectively compare data across different projects and ensure data quality and security. Summary of the Invention

The data quality verification module automatically checks the compliance, integrity, and consistency of the delivered data during the data delivery process and generates a delivery inspection report.

[0013] Furthermore, the method for constructing the digital delivery standard system includes: Comprehensive analysis steps: Comprehensive analysis of relevant domestic and international standards such as ISO15926, CFIHOS, Q / SY01015-2017, and GB / T51296-2018; Integration steps: Integrate with the China National Offshore Oil Corporation (CNOOC) enterprise standard Q / HS5069—2019 Specification for Digital Collection of Offshore Oil (Gas) Field Engineering Information; Customization steps: Based on the characteristics and professional division of labor in offshore oil engineering EPC business, the standard is improved and modified from the perspectives of business processes, management methods, and delivery platform functions.

[0015] Furthermore, the business logic layer is implemented based on a microservice architecture, including application delivery services, project delivery services, process services, and lightweight engine services.

[0016] Furthermore, the lightweight engine service supports lightweight display in RVM, FBX, IFC, and STEP formats, and uses WebGL technology to display 3D models on the browser side, responsible for lightweight processing and display of 3D models.

[0017] Furthermore, the synchronization management module extracts delivery files from the data pool through the ETL process, converts them into a delivery data organization form according to the delivery standards, and realizes data linking based on tag number, thereby realizing the automatic data delivery process.

[0018] Furthermore, the standard mapping management module enables data conversion between different standards by delivering dictionaries and mapping relationship configurations. The conversion process includes: data import, standard matching, field mapping, data conversion, and data output.

[0060] (5) Automated delivery technology.

[0061] Data linking based on tag number enables an automated data delivery process. Delivery process: Retrieve data from the data pool → Classify data according to delivery standards → Establish tag associations → Generate deliverables; Deliverables include: structured data, documentation, 3D models, etc. Delivery verification: Through the data quality verification mechanism, the system automatically checks the integrity and consistency of the delivered data during the data delivery process, generates a delivery inspection report, and ensures that the delivered data meets the requirements of the digital delivery standards for offshore oil and gas engineering.

Data Preparation Phase: Based on the project's business process requirements, the digital delivery platform first obtains design data from the "data pool"; the design data is categorized according to the offshore oil engineering delivery standard library, and each object accesses the field data required by its library according to the category content; by calling the dp-project / syncData / sync interface, the synchronization type and synchronization parameters are configured to achieve automatic data synchronization.

[0063] 2. Data Processing Phase: The delivery platform automatically imports 3D models, intelligent P&ID diagrams, design drawings, and other data obtained from the "data pool" and completes automatic parsing; it saves class library property configurations by calling the dp-project / categoryProperty / save interface; it establishes a mapping relationship between objects and tag numbers by associating objects with tag numbers; the delivery platform obtains drawings and documents from the "data pool" for the design, construction, installation, commissioning, and special design phases; it classifies documents according to the document classification requirements of the offshore oil engineering delivery standards (classified and stored according to design phase, professional discipline, and file type); and it imports document property configurations by calling the dp-app / sdDocumentProperty / importProperty interface.

Based on digital delivery standards, over 2,000 relationships were established and over 30,000 attributes were parsed through the delivery platform.
