The characteristics of general cargo ships 2021-06-20 13:15:19 general cargo ships, also known as ordinary cargo ships. It is a merchant ship whose main business is the shipment of spare parts. Most of them sail regularly on fixed routes, and there are also round-the-world routes between the two ports, triangle routes or certain waters. General cargo ships generally have the following characteristics: (1) General cargo ships have a strong longitudinal structure, and the bottom of the hull is mostly a double-layer structure. (2) The bow and stern are equipped with front and rear pointed cabins, which can be used to store fresh water or load ballast water to adjust the trim of the ship. In the event of a collision, it can prevent seawater from entering the large cabin, which plays a role of safety protection. (3) In order to facilitate cargo handling, general cargo ships generally have 2 to 3 decks. A general cargo ship with a deadweight of 10,000 tons has 5 to 6 cargo holds. (4) Many 10,000-ton general cargo ships often have deep tanks due to ballast requirements, and deep tanks can be used to carry liquid cargo (animal and vegetable oils, molasses, etc.). (5) General cargo ships are generally equipped with lifting devices, most of which are mainly booms, and some are equipped with hydraulic rotary cranes.

(7) Unscheduled general cargo ships are generally low-speed ships. Excessive speed is very uneconomical for general cargo ships. The speed of ocean-going general cargo ships is 14-18 knots, and the endurance is more than 12,000 nautical miles; the speed of offshore general cargo ships is 13-15 knots; the speed of coastal general cargo ships is 11-13 knots.
