Description

Technical Field

[0001] This invention relates to the field of intelligent technology for marine oil engineering, and more specifically, to a method for constructing a digital twin platform for offshore oil platforms. Background Technology

[0002] The harsh environment of offshore oil platforms and the flammable and explosive nature of oil products pose significant challenges to the operation and maintenance of oil and gas companies, requiring safe and flexible responses. As relatively fixed industrial oil extraction and crude oil processing systems, the independence and relative dispersion of offshore oil platforms lead to deficiencies in the overall development and utilization of data. Issues include: abundant IoT data with unintuitive perception; difficulty in integrating and utilizing cross-business data; scattered and disorganized documentation, resulting in high management pressure and difficulty in searching; and complex operations leading to unscientific decision-making. Therefore, it is suitable to utilize digital twin technology to build a comprehensive management platform to gradually achieve intelligent production on offshore oil platforms.

[0003] Digital twins fully utilize physical models, real-time sensor data, and operational history to integrate multi-disciplinary, multi-physical, multi-scale, and multi-probabilistic simulation processes, completing a mapping in virtual space to reflect the entire lifecycle of the corresponding physical device. Digital twins are a concept that transcends reality; they can be viewed as digital mapping systems of one or more important, interdependent device systems.

[0004] Due to their unique characteristics, offshore oil platforms started their digital transformation relatively late, but they have begun active exploration. Currently, there are few research results on the design and construction of digital twin systems for offshore oil platforms in China. Although some applications of digital twins have been explored and 3D visualization has been achieved, the application of combining models and data is limited, especially the application and mining of data. Research on key technologies for constructing digital twin systems for offshore oil platforms is still immature.

[0005] Therefore, how to utilize the concept of digital twins to study the construction method of digital twin systems for offshore oil platforms, and realize the virtual-real interaction between the physical offshore oil platform and the model by constructing a digital twin system for offshore oil platforms, and predict the fatigue state and operation and maintenance state of offshore oil platforms during their life cycle of production and operation, has become an urgent technical problem to be solved in order to meet the needs of offshore oil platform production operation scheduling, safety monitoring, energy consumption management and other requirements.

[0102] In this step, a 3D scene is constructed to obtain a 3D model, enabling scene browsing and control. Using professional 3D modeling software and the UE4 platform and its plugins, the overall structure of the offshore oil platform is 3D modeled, and the production equipment, pipeline system, etc. are digitally restored in ultra-fine 3D.

The platform structure model accurately restores the overall structure and layout of the offshore oil platform. The production equipment includes the appearance, size and functional characteristics of various production equipment on the platform. The pipeline system includes details such as pipeline routing and valve location.

[0105] S032: Use the Datasmith tool to convert the built platform model into a model format that can be directly edited and manipulated by Unreal Engine;

[0119] (2) Connect to the central control system data to intuitively and conveniently control the equipment operating status in the three-dimensional scene;

[0120] (3) Alarm data is linked to three-dimensional scenes, providing timely reminders, efficient positioning, and precise operation and maintenance;

[0121] (4) Comprehensive situation can be grasped with a single map, and the operational trend can be scientifically controlled;

[0122] (5) Access to equipment data for precise operation and maintenance;

[0123] (6) By using the three-dimensional scene layered positioning, when equipment malfunctions occur, the system can promptly remind you and automatically jump to the corresponding equipment location in the linked scene, control the layering of the three-dimensional model, so as to facilitate browsing the equipment distribution location, the relationship with surrounding equipment pipelines, and specific alarm details through the three-dimensional scene perspective.

[0128] (4) Real-time data access and real-time push of PLC instruments are achieved through the OPC / WebSocket protocol.

[0129] S05: Develop application scenarios and, based on business needs, develop digital twin applications for offshore oil platforms using digital twin scenarios.

[0130] Specifically, step S05 includes the following steps S051-S055:

[0131] S051: Develop data visualization functions to enable managers to intuitively see the real-time data and status of each part of the platform. This helps managers quickly understand the operation of the platform and make corresponding decisions.

[0132] S052: Develop roaming inspection function and build virtual inspection scenarios to allow managers to conduct roaming inspections in a virtual environment. This helps reduce the cost and risk of on-site inspections and improve inspection efficiency.

[0133] Specifically, step S052 further includes the following steps S0521-S0523:

[0134] Step S0521: Develop an immersive roaming inspection function based on the UE4 engine to realize first-person immersive roaming in the three-dimensional scene of the offshore oil platform, freely browse the indoor and outdoor environment of the platform, display the equipment status in real time during the roaming process, control the equipment alarm in a timely manner, and carry out inspection and management intuitively and accurately.

[0135] Create a first-person character controller in UE4 and configure parameters such as character movement, rotation, and view switching;

[0136] Design the interaction logic between the character and objects in the scene (such as devices, switches, etc.) to ensure that the character can interact with the environment;

[0137] Connect to data interfaces to acquire real-time operational status data of offshore platform equipment; map equipment status data to corresponding equipment in the 3D model, and intuitively display equipment status by changing colors and displaying status indicator lights; write scripts to monitor data interfaces to ensure that equipment status data can be updated in the 3D scene in real time; set alarm logic based on equipment status data to trigger alarms when equipment status exceeds the normal range; and display alarm information in the 3D scene through sound, pop-ups, color changes, etc., to ensure that inspection personnel can notice problems in a timely manner.

[0138] Step S0522: Develop a customized roaming inspection function based on the UE4 engine. On the basis of the immersive roaming function, customize the inspection route, and the scene will automatically roam along the route to display the status of the devices in the field of view in a timely manner. Alarm events can be detected in a timely manner, freeing up your hands, breaking through the time and space limitations, and realizing efficient and accurate inspection.

[0139] Based on the inspection requirements, tools such as Nav Mesh are used in UE4 to plan the inspection route and complete the path planning;

[0140] Write scripts or blueprints to enable characters to automatically roam along preset routes, achieving automatic scene roaming;

[0141] Adjust the inspection route according to actual needs to ensure coverage of all critical areas and equipment;

[0142] Through data interface development and data mapping display, the device status can be displayed synchronously and alarm events can be detected and alerted during roaming.

[0143] Step S0523: Develop a roaming path editing function based on the UE4 engine, which supports custom editing of inspection routes, fully adapts to the inspection work content, and can realize the saving and scheduling of multiple routes, improve the degree of freedom, and fully play the role of roaming inspection.

[0144] Design the user interface for the path editing tool, including the toolbar, editing area, and properties window;

[0145] The path editing functions, including adding nodes, editing nodes, connecting paths, and adjusting parameters, have been developed and completed.

[0146] The functions for saving, managing, and scheduling routes have been developed and completed.

[0147] By developing data interfaces and displaying data mapping, the device status can be displayed synchronously and alarm events can be detected and alerted during roaming.

[0148] In this step, within the digital twin scenario of the offshore platform, roaming patrol routes are planned and set up, enabling the saving and scheduling of multiple contingency plans. It allows for first-person perspective patrols within the digital twin scenario, with real-time data presentation during the patrol process, overcoming time and space limitations. This allows for comprehensive and multi-scale precise control of the overall situation of the offshore platform without leaving the site.
