And each lower hull 2 has a cabin for holding articles, compared with the prior art that the hull body 10 of the multi-hull ship (shown in figure 1) is provided with the sheet body 20 at two sides instead of the hull body, the multi-hull ship provided by the invention has larger displacement and waterplane area, thereby increasing the loading capacity and stability of the multi-hull ship and improving the anti-overturning capacity of the multi-hull ship; and each lower ship body 2 is uniformly arranged along the width direction of the deck 1, so that uniform support is provided for each position of the deck 1, and the stress uniformity, the stability and the transverse strength of the deck 1 are enhanced.

As shown in fig. 2 and 3, each lower hull 2 is connected to the deck 1 through a longitudinal sheet 3 provided in one-to-one correspondence therewith, and one end of the longitudinal sheet 3 in the height direction is connected to the corresponding lower hull 2, and the other end is connected to the deck 1. The longitudinal sheet 3 has a length direction that is identical to and close to the length direction of the lower hull 2. Compared with the prior art that the hull and the blade body in the longitudinal direction are directly connected with the deck 1, and the hull and the blade body in the transverse direction are connected through the deck 1 or the connecting rod, in the embodiment, each lower hull 2 is longitudinally connected with the deck 1 through the longitudinal blade body 3 and transversely connected through the deck 1, and each lower hull 2 is stably connected with the deck 1 to form an integral structure to resist the storm loads in all directions, so that the stability of the integral structure of the multi-hull ship is ensured; and the interval between the longitudinal sheet bodies 3 and the interval between the lower ship bodies 2 can reduce wind load in the sailing direction, most of sea waves in the sailing direction can penetrate through the interval under severe sea conditions, the impact area between the sea waves and the ship body is reduced, and the impact on the ship body is reduced. Meanwhile, as shown in fig. 2, each longitudinal sheet 3 is provided with lightening holes 301 penetrating in the thickness direction thereof. The lightening holes 301 may be one large hole of a larger size or a small hole of a smaller size with respect to the length size of the lower hull 2. Preferably, the lightening holes 301 are small holes with small size and are distributed along the length direction of the ship body in a plurality. The lightening holes 301 can lighten the empty weight of the ship body so as to increase the load capacity of the multi-hull ship, and when the lateral waves of the ship body impact the ship body of the lower ship body 2, most of the waves can pass through the lightening holes 301, so that the impact of the waves on the multi-hull ship is lightened; and the interval between each longitudinal sheet body 3 and the hollow structures in the sailing direction and the lateral direction of the ship body formed by the lightening holes 301 can reduce the impact of wind and wave loads in all directions on the ship body, obviously improve the wave resistance and the anti-overturning capacity of the multi-hull ship, enable the multi-hull ship to better adapt to severe sea conditions and ensure the safety. In summary, the multihull ship provided by the embodiment improves the safety performances such as structural stability, wave resistance, resistance to wind and wave load, anti-overturning capability and the like of the whole ship body, and can better adapt to severe sea conditions; and the loading capacity of the ship body is increased, and the operation capacity is improved.

It should be noted that the height direction of the longitudinal sheet 3 refers to the vertical direction as shown in fig. 2, and the thickness direction refers to the width direction of the deck 1, i.e., the lateral direction as shown in fig. 2.

In order to improve the structural strength and stability of the whole multi-hulled vessel, as shown in fig. 3, a cross brace 4 connecting any two adjacent longitudinal sheets 3 in the width direction of the deck 1 may be provided therebetween. One end of the cross brace 4 is inserted into one longitudinal sheet body 3, and the other end is inserted into the adjacent longitudinal sheet body 3, or the cross brace 4 is an integral transverse connecting rod, one end of the cross brace is inserted into the longitudinal sheet body 3 at one outermost side, and the other end of the cross brace penetrates through each longitudinal sheet body 3 in the middle and then is inserted into the longitudinal sheet body 3 at the other outermost side. Preferably, as shown in fig. 4, the wale 4 is provided in plurality, distributed along the length direction of the hull. The wales 4 improve the connection strength between the adjacent two lower hull bodies 2, and the longitudinal sheet bodies 3 and the wales 4 form a crossed net structure, so that the structural strength, the connection stability and the stability of the whole multi-hull ship are improved.

The thickness of each longitudinal sheet 3 may be the same as the width of the upper end surface of the lower hull 2, or the thickness of the longitudinal sheet 3 is smaller than the width of the upper end surface of the lower hull 2, that is, the interval between two adjacent longitudinal sheets 3 is larger than the interval between two corresponding lower hulls 2; the cross-sectional shape of the longitudinal fins 3 may be the same as or similar to the contour of the upper end face of the lower hull 2, while the vertical section may be rectangular, as shown in fig. 3: the vertical section of each longitudinal sheet 3 is a structure with wide upper and lower ends and narrow middle part, and the middle narrow part is in smooth arc transition to the upper and lower ends, that is, both side surfaces 302 of the longitudinal sheet 3 are smoothly connected arc surfaces. The waves in the lateral direction of the ship body flap on the lower ship body 2, the waves can roll upwards, the structure of the longitudinal sheet body 3 is arranged as shown in fig. 3, the impact force of the waves on the ship body can be reduced along the flowing direction of the waves, and the impact force of the waves on the ship body can be reduced on the basis of reducing the impact area of the waves on the ship body through the lightening holes 301.

Note that the two side surfaces 302 of the longitudinal sheet 3 refer to two opposite surfaces of the longitudinal sheet 3 in the thickness direction.

In order to reduce the sailing resistance and increase the sailing speed, as shown in fig. 2, 4 and 5, the two lateral surfaces 302 of the longitudinal sheet 3 at the bow position gradually come together in the stern-to-bow direction until they merge to form a blade-like structure 303 at the bow position. When the multi-hull ship encounters sea waves in the sailing direction, the blade-shaped structures 303 can form the effect of splitting the sea waves, and the sailing resistance is reduced.

Further, as shown in fig. 5, the cross-sectional dimension of the blade-like structure 303 is gradually reduced in the direction from the deck 1 to the lower hull 2 so that the dimension of the connection surface of the longitudinal blade 3 with the lower hull 2 at the bow position is smaller than the dimension of the connection surface of the longitudinal blade 3 with the deck 1 and also smaller than the dimension of the upper surface of the lower hull 2. In normal sailing conditions, the water plane is located on the lower hull 2, while in severe sea conditions the multihull vessel undulates up and down in the sea, and the water plane is located on the upper surface of the lower hull 2 or on the longitudinal sheet 3, reducing the cross-sectional dimension of the lower end of the blade-like structure 303 at the bow position further reduces the resistance in the sailing direction and the impact of the sea on the hull.

For the same purpose, the lower hull 2 is provided with a toe 202, as shown in fig. 5, the toe 202 having a tapered configuration with a gradually decreasing size in the direction from the stern to the bow. And a bulbous bow 201 structure is arranged at the bow of the lower hull 2. By the arrangement, the sailing resistance can be reduced to the maximum extent and the ship speed can be improved by utilizing structural improvement. While the lower end of the blade-like structure 303 of the longitudinal blade 3, which has a smaller cross-sectional dimension, corresponds exactly to the boat tip 202.

A propeller group consisting of a plurality of propellers may be provided at the stern of the lower hull 2 to increase the sailing speed of the multi-hulled vessel.

In some embodiments, the deck 1 of the multi-hulled vessel may be provided with multiple layers to increase the load carrying space. The space between adjacent decks 1 can be divided into mutually separated grid-shaped structures by the longitudinal bulkheads and the transverse bulkheads which are arranged in a crossed manner, so that the storage space is separated, and the independent placement and management of different cargos or different working tools are facilitated.

The upper layer of the deck 1 may be provided with upper buildings for performing various offshore work activities, and as shown in fig. 1, the positions, the number, and the functions of the upper buildings may be specifically set according to the kinds of work. Preferably, the superstructure is arranged at a distance less than 0.4 times the total length or width of the deck 1, and the superstructure has a small influence on the structural strength of the hull, and may even be considered to have no influence on the structural strength of the entire hull, facilitating the structural design and strength maintenance of the deck 1, the longitudinal fins 3 and the lower hull 2.

It should be noted that the connections between the various components referred to above can be made by welding, such as the connection of the longitudinal blade 3 to the deck 1 and the lower hull 2. Due to the large size of the ship body, the welding is convenient and fast, and the strength of the joint can be ensured.
