Offshore mobile platforms are important facilities for the development of deep-water offshore oil and gas resources. In life-cycle safety assessment of offshore mobile platforms, there remains a lack of effective structural corrosion models to guide design evaluation. From a large amount of corrosion data provided by the China Classification Society regarding the operation of offshore mobile platforms, relevant data were statistically analysed, and available corrosion data were selected for analysis and comparison. By analysing the experimental data of offshore mobile platforms, it was verified that the corrosion rate of local components of offshore mobile platforms follows the Weibull distribution, which is consistent with Paik's verification that the corrosion rate of local components of marine mobile platforms follows Weibull distribution. Therefore, the corrosion evolution model of local components of offshore mobile platforms was established by referring to the ship corrosion rate model.
