Description

A kind of ship auxiliary launching system

technical field

The invention relates to the field of shipbuilding, in particular to a ship auxiliary launching system.

Background technique

The ship built in the dock needs to be launched for outfitting. At this time, the power system of the ship has not been installed, and the ship is in a powerless state. At present, when the ship built in the dock is launched for outfitting, a tugboat is generally used for towing. Towing the ship built in the dock to the corresponding berth, the current method has the following shortcomings. Since the tugboat is fixed at the stern of the ship through ropes to drag the ship into the water, the towing force in the whole process only acts on one or two of the stern of the ship. On the other hand, the tugboat has poor control over the ship. During the movement of the ship in the dock, it is easy to cause the hull to collide with the dock, resulting in damage to the hull.
