[0002] With the increasingly frequent trade exchanges among countries, the diversification of transported products, and the development of the industry, there is a great demand for crude oil in various countries. However, the distribution of oil tanker sources is uneven, and a large number of oil tankers are needed to undertake the transportation tasks.

[0003] An oil tanker is a special ship with special equipment and special requirements. The oil in the oil tank needs to be heated by steam, and the heated steam becomes water through the steam trap group and returns to the atmosphere condenser. The pipe entering the tank is called the steam pipe, and the pipe leaving the tank is called the condensate pipe. The number of steam pipes is determined according to the tank volume. In the traditional practice of the prior art, the connection of the main steam pipe and branch pipes entering the tank and the main condensate pipe and branch pipes leaving the tank are all assembled on site. Multiple condensate pipes and steam pipes need to be hoisted, which requires the cooperation of a gantry crane. The production cycle is relatively long, and a large amount of labor is consumed.
