[0031] like Figure 1 As shown, this embodiment of the invention provides a method for strength verification of an offshore transformer platform, including:

[0032] S101. Obtain Platform Data: By obtaining the platform's design and environmental data, the structural design and construction process of the platform are evaluated using these data. For example, design data includes construction drawings, material reports, and installation records. Utilizing these documents for strength analysis of the transformer platform is of significant importance, as they provide a comprehensive and detailed data foundation for strength analysis, making the analysis results more accurate and reliable. First, the construction drawings detail the structural layout, dimensional parameters, and detailed design of the transformer platform. Analyzing these drawings allows for a deeper understanding of the overall structure of the platform and the interrelationships of its various components, thus enabling a preliminary assessment of its structural strength. Simultaneously, the construction drawings can help identify potential structural weaknesses or design flaws, providing direction for subsequent strength analysis and optimization. Second, the material reports provide detailed information on the materials used in the transformer platform, including material types, performance parameters, and quality standards. Analyzing these reports reveals key properties such as material strength, toughness, and corrosion resistance, thereby determining whether the platform meets design requirements and the needs of the operating environment. Finally, the installation records reflect the actual conditions of the transformer platform during construction and installation. Analyzing installation records allows us to understand whether the platform was constructed strictly according to the construction drawings and material requirements, and whether there were any improper operations or potential problems during installation. This information is of significant reference value for assessing the overall quality and strength of the platform. Environmental data includes marine environment, wave levels, tidal changes, and seawater corrosion data. The marine environment is a complex and variable system, including factors such as temperature, salinity, and water flow. These factors can lead to corrosion, aging, or performance degradation of the platform's structural materials, thereby affecting the platform's overall strength. Wave levels are a crucial factor affecting platform strength. Under strong winds and large waves, the platform may be subjected to enormous impact forces and dynamic loads, which can lead to structural deformation, connection failure, or overall instability. Therefore, accurately assessing the impact of wave levels on platform strength is key to ensuring the platform's safe operation. In addition, tidal changes also affect the strength of the platform. With the rise and fall of the tide, the platform may experience periodic stress changes. Long-term effects may lead to structural fatigue and performance degradation. Especially under extreme tidal conditions, the platform may face greater loads and challenges. Finally, seawater corrosion is another factor that cannot be ignored. The salt, oxygen and other chemicals in seawater may react with the platform materials, leading to material corrosion and performance loss. This corrosion will not only reduce the strength of the materials, but may also cause structural defects and safety hazards.

[0033] S102. Analyze the platform based on the acquired data; model the platform structure using the acquired data, and simulate and analyze the structural deformation of the platform under extreme working conditions. Specifically, finite element analysis software is used to model the platform structure. Construction drawings, material reports, and installation records provide accurate data input for the finite element analysis software modeling. Next, using the finite element analysis software, a three-dimensional model of the platform can be constructed. By setting parameters such as the model's geometry, material properties, boundary conditions, and loads, the stress conditions of the platform in the actual operating environment can be simulated. Especially for extreme working conditions, such as strong winds, giant waves, and extreme tides, corresponding loads and boundary conditions can be set to simulate the platform's structural response under these extreme conditions. After modeling, the finite element analysis software performs a large number of numerical calculations to solve for the stress distribution and deformation of the model under extreme working conditions. These calculation results help us to deeply understand the structural performance of the platform under extreme conditions and identify potential weaknesses or risks. In addition, after analyzing the platform based on the acquired data, the process includes conducting on-site measurements to collect actual deformation and stress distribution data. This data is then compared and verified with the simulation results. During the on-site measurements, specialized measuring equipment and techniques are employed to accurately measure the platform's actual deformation and stress distribution. By comparing the simulation results with the actual measurement data, the accuracy and reliability of the simulation model can be evaluated, and potential differences or deviations can be identified. If the comparison results show significant discrepancies between the simulation results and the actual measurement data, the simulation model settings and parameters need further examination to confirm any omissions or errors in the modeling process. Simultaneously, other influencing factors that may exist in the actual operating environment, such as differences in environmental conditions and changes in material properties, need to be considered. These factors may affect the platform's actual deformation and stress distribution. Through comparative verification, a more comprehensive understanding of the platform's actual performance can be obtained, identifying potential problems and risks. Based on the actual measurement data, the platform's structure can be further optimized and improved to enhance its strength and stability.

[0034] S103. The analyzed platform is evaluated. This evaluation includes fatigue testing and ultimate strength testing to assess the platform's strength changes under extreme conditions. For example, in the test, alternating loads of specific frequency and amplitude are applied to simulate the long-term vibration and stress cycles the platform may experience in the actual operating environment. By observing and analyzing structural deformation, crack propagation, and other phenomena in the fatigue test, the fatigue life and durability of the platform structure can be evaluated. In the test, the load is gradually increased until the platform reaches its failure point, and the structural response and failure mode of the platform at different load levels are recorded. Through ultimate strength testing, the strength limit and failure mechanism of the platform under extreme conditions can be understood, providing important references for the safe design and operation of the platform. By combining the results of fatigue testing and ultimate strength testing, the strength changes of the platform under extreme conditions can be comprehensively evaluated. These test data not only help verify the accuracy of the simulation results but also provide targeted suggestions for the optimized design and improvement of the platform.
