The invention relates to a pipeline layout structure for a ship ballasting system. The pipeline layout structure for the ship ballasting system comprises a seawater master pipe, wherein the seawater master pipe is connected with a ballasting pump through a pipeline; a pump inlet valve is mounted on the pipeline; two pipelines exist at an outlet of the ballasting pump; one pipeline is a ballasting chamber entering pipeline; the other pipeline is an out-board draining pipeline which leads to the outside of a ship and is used for draining water in a ballasting chamber out of a board; an air pipe is mounted at the top of the ballasting chamber; a return pipeline is connected between the pipeline and the ballasting chamber; a return valve is mounted on the return pipeline; an elbow is mounted on the out-board draining pipeline; and the position of the top of the elbow is higher than the top of the ballasting chamber and lower than the top position of the air pipe. The elbow is 1-2 m higher than the top of the ballasting chamber. The top of the elbow is connected with a vent pipe. According to the invention, overpressure water and ballast water in the ship ballasting chamber can be prevented from overflowing to a deck so that daily works of sailors are ensured.
