Can you distinguish the ship's register, flag and class?

Ship's class

It is a kind of norm and standard for supervising the construction of ships, and the corresponding authority exercising the right is the classification society. All ships of more than 100 gross tons need to obtain classification society certification. Different classification societies have different requirements for ship construction technical indicators. The classification society is selected before a ship is built, and the design drawings should be approved by the classification society. After the completion of the construction of the ship, the classification society shall inspect the ship according to its technical standards and issue a certificate.

Classification society certification contributes to the safe navigation of ships and proves that they meet the technical requirements for safe operation.

The world's more famous classification societies are China Classification Society (CCS), Lloyd's Register of Shipping (LR), German Lloyd's Register of Shipping (GL), and Norwegian Classification Society (DNV). Among them, GL and DNV have been merged into DNV-GL.

China Classification Society (CCS) is the only professional institution engaged in ship classification and inspection business in China, with more than 80 branches covering major ports at home and abroad, forming a global service network covering Asia, Europe, America, Africa and Oceania. At present, the government of 34 countries or regions is authorized to carry out statutory surveys for ships flying the flag of these countries or regions.
