Half-ship floating state monitoring method

The invention belongs to the technical field of ship construction, and discloses a half-ship floating state monitoring method, which comprises the following steps of: S1, respectively assembling liquid level detection devices at a plurality of positions on the outer side of a half ship; s2, the dock is opened to enter water to enable the half ship to float, after the half ship floats stably, the dock is closed to pump water, and a plurality of liquid level detection devices are started to monitor the height value H between the liquid level detection devices and the liquid level of the dock; and S3, the half ship is leveled by adjusting ballast water on all sides of the half ship, so that the height values H between all the liquid level detection devices and the liquid level of the dock are equal until the half ship falls on the pier. According to the half-ship floating state monitoring method, liquid level detection devices are installed on the periphery of an unconstructed half-ship, in the pier falling proc
