Abstract: A ship weighing system and a weighing method thereof include a collection module, a computing server, a wireless router, a display control terminal, and a network switch, which are installed in the ship. The collection module synchronously collects water level data of a stern and trim angle data of a front portion, a middle portion, and a rear portion of the ship. The computing server respectively calculates, based on the water level data collected by the collection module, an accumulated volume of the ship below a slice section parallel to a bottom plane of the ship corresponding to the water level data and a volume of a trim wedge formed by the slice section and an actual horizontal plane. The computing server combines results and corrects a volume of a vertical arch wedge in the middle portion of the ship to obtain a displacement volume of the ship.
