In the context of promoting green and low-carbon energy development and structural transformation, traditional energy technology urgently requires innovation and enhanced capabilities. Therefore, intelligent technology for marine engineering equipment is rapidly advancing but faces challenges such as weak independent innovation capabilities, lacking some critical core technologies, and insufficient supporting capacities for key components. To drive the intelligent development of marine engineering equipment and accelerate the construction of intelligent marine engineering equipment, this paper reviews the practical innovations of key equipment in the development of marine oil and gas resources. This includes three research areas: Marine flexible risers and umbilical, marine floating structures, and monitoring technology for marine structures. Firstly, by systematically expounding the current development status of marine flexible riser and umbilical, intelligent algorithms in structural analysis and design are summarized. Secondly, the development progress of intelligent marine floating structures is introduced and the limitations of current analysis technology and future research directions are highlighted. Lastly, the application research of intelligent monitoring technology for marine equipment structures is reviewed and monitoring technology as a crucial pathway for intelligent perception is emphasized. With the rapid advancement of information technology, traditional automation methods are inadequate to address new challenges in the marine equipment maintenance process. The article suggests that comprehensive application of various intelligent technologies such as full perception, real-time interconnection, analysisbased decision-making, autonomous learning, dynamic prediction, and collaborative control in marine engineering equipment should be an inevitable trend for future development.
