An underwater pipeline tapping machine was successfully developed. The systematic composition, main technical parameters, driving principle and technical solution of the tapping machine were described. The underwater pipeline tapping machine meets working needs by introducing such design as using hydraulic system as power source, putting transmission box to the bottom of machine, setting safety clutch in feeding system, having fast translation function of the spindle, detecting the spindle translation with differential, using dial to display and seting feed depth. By underwater tapping tests, the tapping machine works normally and reaches the target of design.
