For the container and ship industries, classification societies play a unique role in ensuring the safety of ships with their professional ship technical 

knowledge. Classification societies pass inspections of ships so that they can meet the safety standards required by the government and insurers, 

as well as the safety standards expected by shipowners and the public. The traditional services provided by classification societies mainly include: 

classification services and statutory services. Due to the increasingly fierce market competition in recent years, the relationship between the 

supervisor and the supervised. In addition, the customers faced by classification societies are diverse. For example, in different stages of ship 

construction, the service objects of classification societies are different. In the stage of ship design and construction, the service object of the 

classification society is the shipyard; after the ship is delivered, the service object is transferred to the owner or manager of the ship. Classification 

societies have different basis for different customer services. It can be seen that the legal status of classification societies is special.
