What is the general composition of the ship structure

Ships are means of transport by sea. Ships vary in size, but the main parts of their structure are much the same. A ship mainly consists of the following parts:

(1) Ship Shell

The hull is the shell of the ship, which is made of multiple steel plates riveted or welded together, including three parts of the keel wing plate, the curved outer plate and the upper outboard, which is the main part of the water pressure, wave impact force and longitudinal bending force.

(2) Ship Frame

Ship frame refers to the general term for various materials used to support the hull, its role is to withstand the weight of the hull and ensure the structural integrity of the ship, while also able to absorb and disperse the impact force, protect the hull and hull structure from damage, divided into longitudinal and transverse timber two parts. Longitudinal materials include keel, bottom bone and side bone; The transverse materials include ribs, ship beams and bulkheads. The design and manufacture of ship frame need to take into account the type, use, size and tonnage of the ship and other factors to ensure the safety and stability of the ship.


(3) Deck

The deck is a steel plate laid on the beam of the ship, dividing the hull into upper, middle and lower layers. The number of decks of large ships can be as many as six or seven layers, and its role is an important part of ensuring the safety and stability of the ship. When designing and building a ship, factors such as the strength, durability and maintenance of the ship deck need to be taken into account to ensure the safety and reliability of the ship.

(4) Holds and Tanks

The cabin refers to the space below the deck for various purposes, including the bow cabin, the stern cabin, the cargo hold, the machine room and the boiler room. The main role of these Spaces is to carry cargo and provide a living and working place for the crew. Depending on the type of ship, the type and number of cabins will vary. There are many other auxiliary compartments, such as oil tank, fresh water tank, sewage tank and so on. The main role of these auxiliary cabins is to provide the auxiliary facilities required for the operation of the ship to ensure the normal operation of the ship. In the design and construction of the ship, the layout and structure of the cabin need to be fully considered to ensure the normal operation and safety of the ship.

(5) Super Structure

The ship's surface building refers to the building above the main deck, usually located above the main deck, which is the place where the crew works, lives and stores the ship's equipment. The ship's surface construction includes the bow house, the tail house and the bridge, etc. The bow house is usually located in the bow of the ship to provide the crew with rest and work place; A stern house, usually at the stern, is used for storing gear and other items; The bridge is located in the middle of the ship and is the main place for the crew to work and live. In the design and construction of the ship, the layout and structure of the ship surface building need to be fully considered to ensure the normal operation and safety of the ship.
