Abstract: As a type of offshore oil and gas resource development and extraction equipment, self-elevating drilling platforms play a crucial role in China's offshore petroleum industry. In recent years, with the continuous deepening of offshore oil development, the application of self-elevating drilling platforms has become increasingly widespread, and the corresponding equipment maintenance issues have become increasingly prominent. The quality and efficiency of equipment maintenance directly affect the safe production and oil and gas extraction benefits of the platforms. Analyzes the current maintenance status of self-elevating drilling platform equipment, identifies existing problems and then proposes equipment maintenance strategies applicable to self-elevating drilling platforms in China. This improves the management level of equipment maintenance and ensures the safe and stable operation of drilling platforms.

Key words: self-elevating drilling platform, equipment maintenance, offshore oil
