DOI:
Seafloor core sampling drill is necessary equipment for marine geologic and environmental investigation. A 20 m seafloor core sampling drill is chosen as the study object. Its technical features and at-sea operation are described from the aspects of supporting and leveling mechanism technology, drill string making and breaking, drill rods storage technology, telemetry/telecontrol and high-speed data communication technology, as well as escape technology.
