摘要
A pipe-handling system includes at least two pipe-handling units arranged in a vertically displaceable manner along respective guide tracks of, respectively, first and second portions of a tower. The pipe-handling unit is provided with lower and upper rotary units spaced apart vertically on a chassis. Each of the rotary units is provided with a rotatable tong and a hanging-off device. A method is for inserting and withdrawing a pipe string in/from a borehole by the use of the pipe-handling system.
