[0002] The ship includes open cooling system, deck drainage system, air conditioning condensate, bilge drainage, and domestic sewage treatment systems that meet the standards. The drainage of the above systems is discharged overboard through the side pipes on both sides of the hull. The side pipes are installed on the hull outer plate above the waterline.

[0003] Since the hull outer plate in the installation area of ​​the side pipe is mostly a curved plate, and the curvature of the hull line of the hull outer plate at the bow or stern is greater, when drilling a hole on the hull outer plate for the side pipe, the projection of the hole is a circle, but on the curved surface with a large line change, it is an irregular shape. Therefore, it is difficult to determine the center of the installation circle, resulting in great difficulty in marking and drilling.

[0004] In addition, most ships install the side pipes in the block stage or even the assembly stage. During the block stage or the assembly stage, the deck is not installed, so there is no reference when marking and opening holes, which makes marking and opening holes more difficult. In addition, the opening quality of the hull outer plate directly affects the strength, appearance and corrosion resistance of the hull outer plate.
