讲了船级社，那么有了IMO号码如何查询船级社.
以9232448 为例子
第一步去网站上搜
https://www.nialexisplatform.org/certification/dynamic-positioning/check-vessel-classification/
必须输入船名和IMO UNMBER.
Class Requirements
Based on IMO (International Maritime Organization) publication 645 (IMO MSC/Circ.645, Guidelines for vessels with dynamic positioning systems) the Classification Societies have issued rules for Dynamic Positioned Ships described as Class 1, Class 2 and Class 3.
Equipment Class 1 has no redundancy: loss of position may occur in the event of a single fault.
Equipment Class 2 has redundancy so that no single fault in an active system will cause the system to fail. Loss of position should not occur from a single fault of an active component or system such as generators, thruster, switchboards, remote controlled valves etc. But may occur after failure of a static component such as cables, pipes, manual valves etc.
Equipment Class 3 which also has to withstand fire or flood in any one compartment without the system failing. Loss of position should not occur from any single failure including a completely burnt fire sub division or flooded watertight compartment.
2.网站去试
试的时候搜Classification Society
以为例子

这个就需要你开会员才能看到，单次查询的话，没有必要。
换第二个
https://www.vesseltracker.com/en/Ships/Eternal-8-9232448.html
这个也是看不到。
换第三个
https://www.balticshipping.com/vessel/imo/9232448
