The invention provides an installation method of a marine drilling platform pipe arranging machine. The pipe arranging machine comprises an upper pulley, a lower pulley and a stand column. The installation method comprises the steps that the upper pulley is installed on a derrick, the lower pulley is installed on a main hull deck of in a drill pipe stand area, and the upper pulley and the lower pulley can slide in parallel in the same direction of the port side and the starboard side; a connecting tool is fixedly mounted on a sliding path of the lower pulley on the main hull deck of the drillpipe stand area, wherein the height of the connecting tooling is smaller than the height of the lower pulley; the stand column is integrally lifted and tilted and then sent to the derrick from an opening of the derrick, and then the stand column is integrally lowered to enable the lower end of the stand column to be sent into the drill pipe stand area and rotatably connected to the connecting tool; the stand column is adjusted to be in a vertical state by using the connecting tool as a fulcrum; and the connection between the stand column and the connecting tool is released, the connecting toolis removed, and the upper end and the lower end of the stand column are separately connected with the upper pulley and the lower pulley.
