The deepwater artificial seabed(DAS) system represents an innovative type of offshore equipment for oil and gas development in deep and remote waters. The DAS system serves as a feasible solution orienting to adaptability to disastrous marine environments, including strong winds, huge waves, high surface currents, and the ultra-high pressure of the seabed. This paper elaborates on the design principles and structural characteristics of the DAS system. On this basis, the current research progress of the DAS system in design and analysis techniques is reviewed, covering the conceptual design, optimization design, hydrodynamic characteristics under ocean waves-currents/internal solitary waves, and the associated safety control mechanisms. Future research directions are proposed towards advancing the sustainable development of the DAS system with independent intelligent property rights, which look forward to playing an essential role in promoting the independent development process of the offshore oil and gas industry in China.
