[0009] Furthermore, a crane with a telescopic boom is selected as the hoisting equipment to reserve sufficient working space for the operation deck; different tonnages of cranes are required in special working conditions during the scientific research process, and a base for the combined use of different tonnage cranes is designed.

[0010] Furthermore, the transmission track of the manned submersible is arranged along the ship's midship and extends from the equipment room to the ship's stern; the bases of the cranes are relatively evenly distributed on both sides of the transmission track according to the tonnage of the cranes.

[0011] Furthermore,

[0012] The A-frame at the stern is arranged at the ship's stern and extends outward along the transmission track;

[0013] A slidable deployment and recovery winch seat is arranged above the transmission track.

[0014] Furthermore, a slideway perpendicular to the ship's midship direction is provided below the recovery winch seat, and a roller fairlead is arranged at the end of the transmission track to realize the left and right sliding function of the system for towing the optical cable.

[0015] Furthermore, a dedicated maintenance operation platform is provided on one side of the transfer track to enable boarding of the submersible.

[0016] Furthermore, several weldable embedded parts and fastening bases are provided on the stern deck for placement and fixation of scientific research equipment.

[0017] Furthermore, electric tracing channels and channel handrails are arranged on both sides of the transfer track.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The present invention solves the key technical problems of five layout modules of the stern operation deck of a new type of multi-functional scientific research ship in the deep and far sea, namely, the selection of lifting equipment, the transfer function of the manned submersible, the deployment, recovery and maintenance functions of the manned submersible, the fixation of movable scientific research equipment, and the safety of personnel passage in the polar environment.
