Description

Technical Field

[0001] The present invention relates to the field of offshore oil and gas field structure design, and particularly to a calculation method, system, processing device and storage medium for a standardized ultra-high strength steel module structure. Background Art

[0002] To adapt to the high-quality development of offshore oil and gas resource development, the current offshore platform structure design is shifting towards standardization and intelligence.

[0003] Through the statistical analysis of data such as the functions, equipment layouts, and environmental conditions of in-service offshore platforms, the prior art has disclosed a set of standardized platform libraries that can cover the entire Bohai Sea area. This standardized platform library contains 9 types of upper modules, called standardized modules. In the future, when designers conduct module structure design, they only need to select the appropriate type in the standardized platform library according to the needs of the module's functions, equipment layout, etc., saving the time of starting from scratch. Currently, this standardized platform library has been successfully applied to oil fields such as Suizhong 36-2 and Kenli 10-2 in China. The standardized module structure is composed of steel plates, beams, columns, etc. According to the different specifications of beams and columns used in the module, a series of steel material libraries that can meet the strength design of the standardized platform structure have been formed. This series of steel material libraries includes high-strength (yield strength of 355 MPa) welded profiles, high-strength profiles, low-strength (yield strength of 235 MPa) profiles, pipe tubes, and seamless steel pipes, etc. The maximum yield strength of the steel currently in use is 355 MPa.

[0004] To meet the future requirements of lightweight and green and low-carbon materials for offshore platforms, ultra-high strength steel with a yield strength of 420 MPa has been introduced. Currently, the designed standardized platform modules also hope to use ultra-high strength steel to achieve weight reduction of the standardized module structure. However, if the 9 types of standardized modules are redesigned using ultra-high strength steel, the manpower and time consumed will be huge. Summary of the Invention

[0023] To meet the future requirements of lightweight and green and low-carbon materials for offshore platforms, ultra-high-strength steel with a yield strength of 420 MPa is introduced. Currently, the standardized platform modules that have been designed also hope to achieve weight reduction of the standardized module structure by using ultra-high-strength steel. However, if ultra-high-strength steel is used to redesign these 9 standardized modules, the human and time costs are huge. Embodiments of the present invention provide a calculation method for a standardized ultra-high-strength steel module structure, including: forming an ultra-high-strength steel upper module model library and an ultra-high-strength steel material library based on the upper module model library of a standardized offshore platform; Performing static, dynamic, seismic, and installation analyses on the ultra-high-strength steel upper module model library; Extracting the maximum UC values of each member in the ultra-high-strength steel upper module model library under static, dynamic, seismic, and installation analysis conditions; Replacing the members in the ultra-high-strength steel upper module model library whose maximum UC values do not meet the preset requirements with members of a larger size in the ultra-high-strength steel material library and performing recalculation until the maximum UC values of all members in the ultra-high-strength steel upper module model library meet the specification requirements, thereby completing the calculation of the ultra-high-strength steel module structure of the standardized offshore platform. The present invention can realize the rapid application of ultra-high-strength steel in the design of standardized platforms. Through software development of computer equipment, this calculation method is programmed to assist the design of ultra-high-strength steel standardized modules by marine engineering practitioners.

[0024] Embodiment 1 As Figure 1 shown, this embodiment provides a calculation method for a standardized ultra-high-strength steel module structure, including the following steps: 1) Using SACS software (Structural Analysis Computer System), construct the upper module model library of a standardized offshore platform.

[0025] Specifically, the upper module model library of the standardized offshore platform includes 9 types of upper modules, including small unmanned wellhead platform modules, medium unmanned wellhead platform modules, gas field unmanned wellhead platform modules, medium manned wellhead platform modules, large manned wellhead platform modules, Type I central platform modules, Type II central platform modules, Type III central platform modules, and Type IV central platform modules. As Figure 2 shown, it shows the schematic diagrams of each upper module model. As shown in Table 1 below, it lists the types of 9 upper modules: Table 1: Types of 9 upper module models in the upper module model library of the standardized offshore platform

[0026] 2) Based on the constructed upper module model library and the steel grades of the upper modules therein, a serialized steel library is formed.

[0027] Specifically, the serialized steel library includes high-strength (yield strength of 355 MPa) welded profiles, high-strength profiles, low-strength (yield strength of 235 MPa) profiles, rolled tubes, seamless steel pipes, etc. These steels can be selected in two different delivery conditions: normalizing and TMCP (Thermo-Mechanical Control Process). Among them, steels with a yield strength of 355 MPa generally adopt the normalizing delivery condition, and when the steel thickness ≤ 75 mm, the TMCP delivery condition can be adopted. As shown in Table 2 below, it lists the model settings, steel yield strength, and delivery conditions of the serialized steel library: Table 2: Models, yield strength, and delivery conditions of the serialized steel library

[0028] Note: ① For H1800×650×45×50, 1800 represents the web height, 650 represents the flange width, 45 represents the web thickness, and 50 represents the flange thickness, with the unit being mm. ② For Ø 2800×50, 2800 represents the outer diameter of the steel pipe, and 50 represents the wall thickness, with the unit being mm.

[0029] 3) Replace the models that meet the requirements in the upper module model library and the serialized steel library with ultra-high-strength steel, and correspondingly reduce the wall thickness of this model to form an ultra-high-strength steel upper module model library and an ultra-high-strength steel library.

[0030] Specifically, replace the profiles with a flange and web wall thickness of 16 mm and above and the tubes with a wall thickness of 16 mm and above in the upper module model library and the serialized steel library with ultra-high-strength steel (yield strength of 420 MPa). At the same time, round up the wall thickness of the profiles and tubes after reducing it by 1 / 6 to ensure that the flexural strength of the members before and after replacement is equivalent.

[0031] More specifically, for steel with a yield strength of 420 MPa, when the steel thickness > 60 mm, it is delivered in the QT (quenched and tempered) state; when the steel thickness ≤ 60 mm, it is delivered in the TMCP (thermo-mechanical control process) state. Table 3 below lists the model settings and delivery states after replacing the serialized steel with ultra-high-strength steel. Steel above H900 is generally welded profiles, and welded plates can be replaced with ultra-high-strength steel. Steel below H700 is generally finished steel and is not suitable for replacement with ultra-high-strength steel: Table 3: Steel model, yield strength and delivery state after replacement with ultra-high-strength steel

[0032] 4) Use SACS software to perform static, dynamic, seismic and installation analyses on the ultra-high-strength steel upper module library. Among them, the analysis using SACS software is the content disclosed in the prior art, and the specific process will not be elaborated here.

[0033] 5) Extract the maximum UC value (Unity Check stress ratio) of each member in the ultra-high-strength steel upper module library under static, dynamic, seismic and installation analysis conditions.

[0034] 6) Determine whether the maximum UC value of each member in the ultra-high-strength steel upper module library is less than 1.0. If so, complete the calculation of the ultra-high-strength steel module structure of the standardized offshore platform; otherwise, replace the member with a maximum UC value ≥ 1.0 in the ultra-high-strength steel upper module library with a member of a larger model in the ultra-high-strength steel library, and repeat steps 4) and 5) until the maximum UC value of all members in the ultra-high-strength steel upper module library is less than 1.0.

[0035] The following uses specific embodiments to illustrate in detail the calculation method of the standardized ultra-high-strength steel module structure of the present invention: Taking the small unmanned wellhead platform (ST-1) in the upper module library of the standardized offshore platform as an example, the functions of this small unmanned wellhead platform include: applied to conventional oil fields with reserves less than 8 million cubic meters, the designed production capacity is 1 to 2 million cubic meters per year, with functions of oil and gas metering and external transportation and water injection, having 12 well slots for 16 wells, and also including 4 legs and 3 decks of 1800 m 3 . The serialized steel library involved in the ST-1 module is shown in Table 4 below: Table 4: Steel models involved in the small unmanned wellhead platform

[0036] Replace profiles with a flange and web wall thickness of 16 mm or more and pipes with a wall thickness of 16 mm or more in the ST-1 block with ultra-high-strength steel. At the same time, reduce the wall thickness of the profiles and pipes by 1 / 6 and round it up to ensure that the flexural strength of the members before and after replacement is equivalent. Members that can be replaced with ultra-high-strength steel are as shown in Figures 3 to 9 the blue members in Figures 3 to 9 . The wall thickness of the replaced ultra-high-strength steel members is less than 60 mm, and the delivery condition of the steel is TMCP. Table 5 below shows the replacement of the members in the ST-1 block: Table 5: Replacement of members of the small unmanned wellhead platform with ultra-high-strength steel

[0037] For the ST-1 block with the introduction of ultra-high-strength steel, conduct static, dynamic, seismic, and installation analyses.

[0038] Extract the maximum UC values of the members of the ST-1 block under the static, dynamic, seismic, and installation analysis conditions, as shown in Table 6 below: Table 6: Maximum UC values of members of the small unmanned wellhead platform

[0039] The maximum UC value of the ultra-high-strength steel member with the model number Ø 610×16 in Table 6 above is 1.05. Replace the members of this model with a maximum UC value ≥1.0 with Ø 762×16, and re-conduct static, dynamic, seismic, and installation analyses. After recalculation, the maximum UC value of the member with the model number Ø 762×16 is 0.95. At this time, the maximum UC values of all members of the ST-1 block are less than 1.0, meeting the specification requirements. After passing the calculation, the member models involved in the ST-1 block are shown in Table 7 below. Due to the introduction of ultra-high-strength steel, the steel weight of the ST-1 block is reduced by about 80 tons, optimizing the steel consumption of the ST-1 block. The use of the TMCP delivery condition also saves the processing cost of the steel, achieving the purpose of saving project investment under the condition that the structure meets the specification requirements: Table 7: Member types of the ST-1 ultra-high-strength steel block
