Unless you intend to class your platform to the Chinese Classification of Shipping, you require their rules. I believe their is no requirement to class a platform in China. But you do required the platform to be certified by one of the four classification societies, name DNV, ABS, Lloyd, and CCS according to "Safety Rules for Offshore Fixed Platforms".
I do have the 1992 version. But a much latter version was issued probably sometimes in 2000 or 2001.
How can I help?
