Semi-submersible mother ship capable of safely and rapidly deploying cluster type unmanned submersible vehicles

The invention relates to a semi-submersible mother ship capable of safely and quickly deploying cluster type unmanned submersible vehicles. A base special for the submersible vehicles is mounted on an exposed deck of a semi-submersible mother ship body; the cluster type unmanned submersible vehicle is tied and fixed on the special base for the submersible vehicle; the ballast water system and the dynamic positioning system are mounted on the semi-submersible mother ship body; and the control room is arranged in the superstructure of the semi-submersible mother ship body. According to the semi-submersible mother ship, through the large-area exposed deck and a large number of special bases of the semi-submersible mother ship, cluster type unmanned submersible vehicles can be carried at a time; through the semi-submersible mother ship ballast system and the dynamic positioning system, the ship body can sink to the water level needed by self-propulsion laying of the unmanned submersible vehicle, the posture and t
