Abstract: In recent years, global energy supply, energy security, ecological environment and other issues have become increasingly prominent, and the development and utilization of new marine energy has become an important way of energy strategies for countries around the world and an important direction of implementing sustainable development strategies. Marine geological disasters are one of the important factors restricting the development of marine economy. Based on the characteristics of new marine energy development and the disaster risks faced by it, this paper summarizes the research contents, technical methods and development trends of marine geological disaster investigation and research discipline, and puts forward the prospect of marine geological disaster risk assessment under the background of land and sea coordination in the new era. It provides reference for enhancing the security and stability of energy supply chain, realizing high-quality energy development in China and building a modern energy system.
