AN SHIP FOR DRILLING THE SEA

摘要

PURPOSE: A drilling ship is provided to control height of a worktable according to difference of water level to conveniently draw a support pile from a soft ground. CONSTITUTION: A drilling ship comprises a worktable(1) for drilling; a supporting pile(2); sliding pipes(3) mounted on the worktable and frame; and a buoy(4) preventing load of the worktable from delivering to the supporting pile. The drilling ship connects the worktable and the sliding pipe on upper and lower frame of a triangle shape with a frame, and installs the buoy on a lower portion of the sliding pipe not to deliver the weight of the worktable into the supporting pipe by generating buoyance. The buoy fixed on a lower portion of the sliding pipe discharges water to generate the buoyance by connecting a pump mounted on the worktable with a water hose(42). The drilling ship moves in a stable state of the ship body by reducing the buoyance through filling the water into the buoy. Thereby, the marine drilling ship moves on a ground by conveniently assembling and releasing.
