Description

Technical Field

[0001] The invention belongs to the technical field of offshore oil engineering, and in particular relates to a method for visualizing an offshore oil engineering construction plan. Background Art

[0002] During the bidding and execution of offshore oil engineering projects, the construction plan is often the most important plan that the owner, supervisor and general contractor pay the most attention to, which directly affects the project progress, cost, safety and quality. Traditional construction plans generally use text combined with drawings to display the plan. For particularly important projects, animations are produced through external resources, which requires a lot of manpower to prepare the model and takes a long time to render. It has the characteristics of long production cycle and high investment, and cannot meet the conventional construction plan visualization needs.

[0003] Therefore, it is urgent to design a visualization method for offshore oil engineering construction plans to solve the above-mentioned problems. Summary of the invention

[0004] The purpose of the present invention is to provide a method for visualizing an offshore oil engineering construction plan, which has the advantages of fast and efficient visual simulation of the construction plan and solves the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of a method for visualizing an offshore oil engineering construction plan of the present invention is as follows: A method for visualizing an offshore oil engineering construction plan comprises the following steps: S1. Preparation of construction site resource model; S2. Lightweight and import of site resource model; S3. Preparation of project model; S4. Merge, split and lighten project models; S5, visualization platform for construction scheme simulation; S6. Export construction simulation animation; S7. Build a report presentation of the simulation animation.

[0006] Furthermore, in S1, according to the construction site drawings, if there is no ready-made model, three-dimensional modeling is performed, and if there is a ready-made model, the existing model is directly used, and the resources such as mechanical equipment involved in the site are modeled.

[0007] Furthermore, according to the design requirements in the construction plan, it is necessary to first determine the number of axles and combination unit types of the SPMT transport vehicle, create the corresponding SPMT transport vehicle model based on the axle number combination, and then convert it into the wlkx format required by the visualization platform and put it into the file location specified by the system for the visualization system to call.

[0008] Furthermore, in S2, the site and resource models are imported into the existing visualization platform. If multiple format models are involved, the formats need to be converted first, and then unified lightweight processing is performed after the conversion. If multiple models are involved, the origin of the site model needs to be set in advance, and other models need to refer to the origin to find the coordinates for accurate positioning.

[0009] Furthermore, in S3, if the project model is relatively complete, it will be exported from the 3D design software. For some bidding projects, if there is no target project model, models of similar projects will be collected to demonstrate the construction plan.

[0010] Furthermore, in S4, the target project model is imported into the visualization platform, and the model is split or merged according to the construction plan demonstration requirements, and lightweight processing is performed. After processing, it is integrated with the site resource model, and the project is accurately located.

[0011] Furthermore, between S4 and S5, the construction plan is converted into an animation script. First, the construction scenes are divided into prefabrication and assembly scenes, final assembly scenes, weighing scenes, transportation and loading scenes, etc. Then, the professions under each scene and the corresponding work content of each profession are determined. After the work content is determined, the project models and auxiliary object models required for each work are listed.

[0012] Furthermore, in S5, the construction plan is previewed and adjusted on the visualization platform, the actual obstacles on the site are simply modeled, and effective avoidance is performed.

[0013] Furthermore, in S6, after completing the simulation required for the construction process, the final version of the simulation process is output as an animation, and the video resolution and format are set as needed during the output.

[0014] Furthermore, in S7, the simulation animation can be split and inserted in combination with the construction plan report PPT, or a demonstration report of the construction plan simulation animation can be made separately.

[0015] The present invention has the following advantages: the present invention breaks through the traditional construction plan display method of text plus drawings, as well as the shortcomings of long cycle and large investment in traditional single animation production, and innovatively applies the existing three-dimensional design model, combined with the developed visualization platform, to achieve the reuse of the site model, the project model is lightweight and the construction process is directly simulated, and the simulation animation can be directly exported for plan reporting or direct display. This method overcomes the time-consuming shortcomings of re-modeling and animation rendering, and the visualization effect can meet the needs of fast and efficient visualization of construction plans in bidding projects and implementation projects in a short period of time.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0018] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0019] Please refer to the attached Figure 1 To Attachment Figure 4 The present invention describes a method for visualizing an offshore oil engineering construction plan.

[0020] At present, in the bidding and execution process of offshore oil engineering projects, the construction plan is often the most important plan that the owner, supervisor and general contractor pays the most attention to, which directly affects the project progress, cost, safety and quality. Traditional construction plans generally use text combined with drawings to display the plan. For particularly important projects, animations are produced through external resources, which requires a lot of manpower to prepare the model and takes a long time to render. It has the characteristics of long production cycle and high investment, and cannot meet the conventional construction plan visualization needs.

[0021] The offshore oil engineering construction scheme visualization method includes the following steps: S1. Preparation of construction site resource model; According to the construction site drawings, if there is no ready-made model, three-dimensional modeling will be carried out. If there is a ready-made model, the existing model will be used directly, and the mechanical equipment and other resources involved in the site will be modeled.

[0022] Preferably, the modeling scope includes the slide area site, the non-slide area site, the dock, the workshop, the dock, etc. In other embodiments of the present invention, the modeling may also include other scopes.

[0023] Preferably, the mechanical equipment involved in the site includes a site gantry crane, a crawler crane, a truck crane, an SPMT transport vehicle, a flatbed truck, a barge, etc. In other embodiments of the present invention, the mechanical equipment involved in the site may also include mechanical equipment involved in other construction plans.

[0024] Furthermore, according to the design requirements in the construction plan, it is necessary to first determine the number of axles and combination unit types of the SPMT transport vehicle, create the corresponding SPMT transport vehicle model based on the axle number combination, and then convert it into the wlkx format required by the visualization platform and put it into the file location specified by the system for the visualization system to call.

[0025] Preferably, the number of axles and the combination unit type of the SPMT transport vehicle include a 4-axle vehicle combination or a 6-axle vehicle combination.

[0026] S2. Lightweight and import of site resource model; Specifically, the site and resource models are imported into the existing visualization platform. If multiple formats of models are involved, format conversion is required first, and then unified lightweight processing is performed after conversion. If multiple models are involved, the origin of the site model needs to be set in advance, and other models need to refer to the origin to find the coordinates for accurate positioning.

[0027] S3. Preparation of project model; If the project model is relatively complete, it will be exported from the 3D design software. Before exporting, the placeholder space models and temporary models used in the modeling process should be screened out, and then the formal model content should be exported to avoid the impact of cluttered model content on the visualization effect, and to maximize the consistency between the model content and the actual construction content.

[0028] For some bidding projects, if there is no target project model, models of similar projects will be collected to demonstrate the construction plan.

[0029] S4. Merge, split and lighten project models; Specifically, the target project model is imported into the visualization platform, Tekla models are imported in IFC format, PDMS models are imported in RVM format, and Smart3D models are imported in VUE format. If models in the above formats are missing, nwd model conversion can also be used to obtain lightweight model data.

[0030] According to the needs of the construction plan demonstration, the models are split or merged and lightweighted. After processing, they are integrated with the site resource model and the project is accurately located.

[0031] Convert the construction plan into an animation script. First, divide the construction scenes into prefabrication and assembly scenes, final assembly scenes, weighing scenes, transportation and loading scenes, etc. Then determine the professions under each scene and the corresponding work content of each profession. After the work content is determined, list the project models and auxiliary object models required for each work.

[0032] Preferably, the auxiliary object model includes a crane, a cushion, etc. In other embodiments of the present invention, other auxiliary object models may also be included.

[0033] S5, visualization platform for construction scheme simulation; Preview and adjust the construction plan in the visualization platform, paying special attention to the need to model the actual obstacles on the site during lifting operations and site transportation operations, and make effective avoidance arrangements.

[0034] Preferably, the preview and adjustment of the construction plan include the travel route of the SPMT transport vehicle and the crane lifting process. In other embodiments of the present invention, the preview and adjustment of the construction plan may include other previews and adjustments.

[0035] S6. Export construction simulation animation; After completing the simulation required for the construction process, the final version of the simulation process is output as an animation. Preferably, the video format, resolution, quality and saving path are set as needed during output. In other embodiments of the present invention, other outputs can be performed as needed during output.

[0036] S7. Build a report presentation of the simulation animation.

[0037] The simulation animation can be split and inserted in combination with the construction plan report PPT, and played according to the display needs of the actual plan. It can also be used as a separate demonstration report of the construction plan simulation animation or a visual display of the construction plan in the bidding project.

[0038] The present invention breaks through the traditional way of displaying construction plans with text and drawings, as well as the shortcomings of long cycle and large investment of traditional independent animation production. It innovatively applies the existing three-dimensional design model and combines it with the developed visualization platform to realize the reuse of the site model. After the project model is lightweight, it can directly simulate the construction process and directly export the simulation animation for plan reporting or direct display. This method overcomes the time-consuming shortcomings of re-modeling and animation rendering, and the visualization effect can meet the needs of fast and efficient visualization of construction plans in bidding projects and implementation projects in a short period of time.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
