Concepts for Drilling and Excavating in and below the Ocean Bottom

摘要: Abstract : In support of planned development construction systems for precise excavation and drilling in the deep ocean floor, a study potential problems which might be encountered has been made. Two Deep Ocean Technology (DOT) efforts are considered, two major subsystems described. The first subsystem is seafloor excavator can shape prepare trenches drill shallow foundation holes. To avoid man undersea environment, this equipment will unmanned, remotely controlled by computer and/or numerical techniques. primary work function similar to conventional milling machine, with ability bore second penetration bottom rock large holes, sealing off cavity prepared steel structure, dewatering, lateral tunneling at one-atmosphere pressure. Initial mining or moles, recent technology disintegration may allow use less massive machine low thrust torque.
