In other embodiments, reinforcements may be provided only on the first ply 110 or the second ply 120.

As shown in fig. 2, in the present embodiment, the reinforcement is provided on the side walls of the first and

second laminates

110 and 120 located within the cavity 130. The presence of the reinforcement on one side inside the cavity 130 on the one hand avoids the occupation of the compartment between the two transverse bulkheads 100 of the ship and on the other hand makes it possible to make the compartment look aesthetically pleasing, while reducing the difficulty of cleaning the compartment.

Of course, in other embodiments, the reinforcement portion may be disposed on the sidewall outside the cavity 130, and is not limited herein.

In this embodiment, the stiffeners include stiffeners, vertical girders 101, and horizontal girders 102. Of course, the type and number of the reinforcing parts can be selected according to the magnitude of the load to be borne by the bulkhead, and the bulkhead can have enough strength.

In this embodiment, the bottom stool 200 has a hollow structure, and the width of the bottom stool 200 is gradually widened from top to bottom. The bottom stool 200 with the structure improves the supporting strength and reduces the overall weight of the ship, and is used as a ballast water tank to enhance the ballast water amount of the ship.

As shown in fig. 1, the bulk carrier further includes a bottom side tank 500, and the lower ends of the first and

second floors

110 and 120 of the partial transverse bulkhead 100 of the ship are connected to the bulkhead of the bottom side tank 500.
