Background

The ship type with high requirement on port entering and exiting maneuverability such as a line container ship, a multipurpose ship and the like often needs to be provided with tail side pushing at the tail part. However, the ship is low in square coefficient, the tail of the ship is thin in line, and the space is very tight. In order to obtain better turning moments in different draught conditions, the aft side thrusts are usually arranged as close as possible to the stern and the bottom of the vessel, i.e. in the area of the stern shaft of the vessel. How to arrange tail side thrust in a narrow tail shaft space is a difficult problem of this type of ship-type design.

The tail side pushing arrangement mode in the prior art is as follows: the tail side push body and the driving motor are integrally supplied and installed; in the ship length direction, the tail side is arranged behind the shaft generator of the gear box in a pushing mode; in the height direction, the tail side push pipe is arranged below the propulsion shaft system; in the ship width direction, the tail side thrust is arranged at one side of the propulsion shafting to avoid the spatial conflict with the propulsion shafting. Under the condition that the length and width spaces of the tail shaft area are sufficient, the arrangement mode can better realize the arrangement of tail side pushing. However, when the line pattern narrows to a certain extent, most of the space in the region of the tail shaft is occupied by the propeller shaft, the gearbox, the shaft generator, the coupling and the structural aggregate. In this case, according to the conventional tail side pushing arrangement mode, it is difficult to find a sufficient space in the tail shaft region to realize the arrangement of tail side pushing.
