In order to find suitable drilling sites in the lake area of Dapengwan Lagoon and its underwater landform, we can focus on the long-term geomorphological evolution of the Dapengwan Lagoon and its extreme disaster events, such as storms, fluvial flooding and even tsunami inundation. The research team used 3D design and digital lamination technology to produce the unmanned hull, and developed a long-distance dual communication system to penetrate and integrate RTK GNSS and underwater sonar. The technical specifications and underwater detection capabilities that are no less than unmanned surface vehicles from other countries. Based on the internal precision assessment, in terms of single-beam underwater potential mapping in Dapeng Bay, can achieve the centimeter-level accuracy level and the IHO special level. The underwater digital terrain model constructed in this study will provide potential selection for underwater drilling areas.
