[0003] In terms of ship form, this type of ship designed by Europeans is a globally recognized, specific ship type. Years of design experience have resulted in a practical combination of principal dimensions and form coefficients. However, existing general ship forms still present some challenges, such as high resistance to navigation, insufficient propulsion performance, limited visibility from the bridge during operation, and the need for improved seakeeping in adverse sea conditions.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0020] Please refer to Figures 1 to 3 An embodiment of the present utility model provides a multifunctional ocean-going tugboat, comprising a hull 1.
[0021] In this embodiment, the right end of the hull 1 is the bow body 2 and the left end is the stern body 3. In actual circumstances, the bow body 2 is the forward end of the hull and the stern body 3 is the stern of the hull. When the hull 1 drives forward, the bow body 2 will be impacted by seawater.
[0022] Furthermore, the overall shape of the bow body 2 of the ship is upright, and when the hull 1 is driven forward, the external waterline is located within the vertical range of the bow body 2 of the ship. In other words, the draft surface is located in the middle of the bow body 2 of the ship. When the hull 1 moves, the bow body 2 of the ship overcomes the obstruction of seawater and moves forward. Since the waterline is located within the vertical range of the bow body 2 of the ship, the underwater part of the forward end of the entire hull 1 can be upright, which can lengthen the waterline length, reduce the bow inflow angle, and reduce the bow resistance. At the same time, the above-water part also remains upright, which can reduce the bow impact and is beneficial to the wavekeeping of the ship.
[0023] A bow thruster 4 is provided on the lower part of the bow body 2 of the ship and on the hull 1. The bow thruster 4 can cooperate with the forward movement of the hull 1 to facilitate the steering of the hull 1. It should be noted here that, in actual working conditions, the bow thruster 4 is an existing equipment and its installation method is also an existing method, so it will not be described in detail here.
[0024] Furthermore, a propeller 5 and a flap rudder 6 are provided at the lower part of the stern body 3 of the ship. In this embodiment, the propeller 5 is two sunken ducted propellers. Since the sunken ducted propeller 5 is adopted at the stern of the hull 1, the diameter of the propeller can be increased under a certain draft of the hull 1, the propeller propulsion efficiency is improved, and the bollard drag of the ship is increased; at the same time, the flap rudder 6 at the stern and the bow thrusters 4 on both sides of the forward end of the hull 1 can greatly improve the turning maneuverability of the ship; it should be noted here that, in actual working conditions, the sunken ducted propeller and the flap rudder 6 are both existing equipment, and their installation method is also an existing installation method, so they will not be described in detail.
[0025] The upper end surface of the hull 1 is a working deck 7. An upper surface of the working deck 7 close to the bow body 2 of the ship is provided with a superstructure 9, and a cab 11 is built on the superstructure 9. In this way, the height of the cab 11 can be increased by the superstructure 9, thereby expanding the driver's field of vision; further, a fire monitor 12 is provided at the upper end of the cab 11, and a bow anchoring mooring system 13 is provided in the superstructure 9.
[0026] A towing winch 8 is provided in the middle part of the working deck 7, and a shark clamp 14 is provided on the end face of the working deck 7 close to the stern body 3 of the ship; a bow pushing frame 10 is fixedly provided above the bow body 2 along the edge of the hull 1, and the bow pushing frame 10 is fixedly connected to the upper end of the bow body 2 of the ship. The function of the bow pushing frame 10 is mainly to facilitate the protection of the forward end of the hull 1; the connection between the bow body 2 of the ship and the bow pushing frame 10 is tilted forward, and the connection between the lower end of the bow body 2 of the ship and the bottom surface of the hull 1 is chamfered, which facilitates the forward movement of the hull 1.
[0027] A multifunctional ocean-going tugboat in this embodiment mainly ensures that the bow of the ship above and below the waterline is upright through the upright design of its forward end, thereby lengthening the waterline length, reducing the bow inflow angle, reducing the bow resistance, and reducing the bow impact; at the same time, the upright bow and twin sunken ducted propellers of the ship can reduce the ship resistance and increase the propulsion efficiency. Compared with ships of similar size, the bollard drag can be increased, and the propulsion fuel consumption rate at the same speed can be reduced.
