This invention belongs to the field of marine technology and discloses a hatch cover system and a cargo ship. The hatch cover system includes a hatch cover body rotatably mounted on the deck of the cargo ship, capable of rotating relative to the deck to switch between a covered state, a side enclosure state, and a deck extension state. In the covered state, the hatch cover body covers the upper part of the deck, thus covering the hatch opening of the cargo hold located below the deck. In the side enclosure state, the hatch cover body rotates to an angle with the deck, at which point it forms a side enclosure structure on the deck. In the deck extension state, the hatch cover body rotates to the outside of the cargo ship, at which point it can carry cargo. This hatch cover system can switch between multiple forms to function as a cover, a wall, and an extended deck area, improving functional integration and space utilization.

Disclosed in the present invention is a hull form of a shallow-draft anti-rolling transport vessel. The hull form comprises a stern section, a cargo hold section and a bow section which are connected in sequence, wherein the length of the stern section does not exceed 30% of the overall length of a vessel; the length of the bow section does not exceed 25% of the overall length of the vessel; the stern section uses a multi-hull structure; the cargo hold section uses a monohull structure; the bottom of the cargo hold section is of a double-bottom structure; the bow section uses a catamaran structure; side flare structures are arranged at both sides of the stern section and the bow section; the stern section, the cargo hold section and the bow section share a main deck; and the main deck is a flat grillage. In the present invention, by means of reducing the draft, a wetted surface area and a wave height during high-speed navigation are reduced, thereby greatly reducing wave-making resistance; and the stability and seakeeping performance of the vessel under severe sea conditions are also taken into account.

This invention discloses a ship bulwark and a ship including the bulwark. The bulwark includes a bulwark body, a sealing plate, and locking components. The bulwark body is fixedly installed on the side of the ship's open deck and has a notch. The lower side of the sealing plate is hinged to the bulwark body. The sealing plate has a blocked position and an open position. When the sealing plate rotates to the blocked position, it blocks the notch. When the sealing plate rotates to the open position, it is located on the outer side of the bulwark body, and its position is lower than the notch. Both ends of the horizontally rotating sealing plate are detachably connected to the bulwark body via locking components, so that the sealing plate can be held in the blocked position. By setting the vertically rotating sealing plate, the notch can be opened to its maximum size, and the rotating sealing plate cannot be separated from the bulwark body, avoiding the need for hoisting or moving the sealing plate. The locking components allow the sealing plate to be quickly locked in the blocked position without the need to tighten a large number of bolts, greatly improving work efficiency and reducing labor intensity.
