Background

At the present stage, China vigorously develops offshore wind power construction, and the water level of part of construction positions is deep or even extremely shallow (the average water depth is less than 3 m). For a shallow water machine position, because the traditional wind power installation platform has deep draught, the shallow water machine position is difficult to enter for construction operation when the shallow water machine position is tide. The current mainstream solution is to use a shallow draft barge to be matched with a crawler crane to carry out shallow water machine position fan hoisting operation, the shallow draft barge enters the machine position when the shallow draft barge is still wet, and the 'static-to-static' hoisting operation required by fan installation is realized in a bottom-sitting mode.

Currently, the hull interior generally includes a middle ballast tank and side ballast tanks disposed on both sides of the middle ballast tank, and the volume of the middle ballast tank is greater than the volume of the side ballast tanks. The ship body is usually provided with a pressure discharge pipeline, one end of the pressure discharge pipeline is arranged at the bottom of the ship and is communicated with seawater, the other end of the pressure discharge pipeline is connected with a ballast pump, the ballast pump is arranged in each ballast tank of the ship body, and the ballast tank is used for containing ballast water. The ballast pump is controlled to pump ballast water into the ship body to submerge the ship body, and the ballast water is discharged out of the ship body to float the ship body.

However, when the ship body needs to rise and fall, if the ship bottom and the seabed are adsorbed, the ship is adsorbed on the seabed and cannot float, so that the construction efficiency is influenced, and in severe cases, the local overload and damage of the ship body and even the breakage of the ship body can be caused.
