The first liquid cargo ship was an oil tanker, which was used to transport crude oil. Now, there are more and more types of liquid cargo ships. According to the different cargoes carried, liquid cargo ships are divided into three categories: oil tankers, liquefied gas tankers, and liquid chemical gas tankers. Oil tankers are special ships that carry bulk crude oil and refined oil; oil tankers can be divided into crude oil tankers and refined oil tankers. Liquefied gas tankers are special ships that carry liquefied natural gas and liquefied petroleum gas. Liquid chemical tankers are special ships that transport various liquid chemicals such as ether, benzene, alcohol, acid, etc. The ship's liquid cargo shore connector refers to the end connector of the cargo oil pipe, fuel oil pipe, and oil and gas recovery pipe in the cargo oil manifold area of ​​oil tankers and chemical tankers. It is a key component for realizing the safe and reliable connection of ship-to-ship and ship-to-shore loading and unloading equipment during the loading and unloading of liquid cargo by liquid cargo ships, and directly affects the entire process of loading and unloading cargo oil by liquid cargo ships.
