［Objective］ This study aims to rapidly evaluate the performance of anticorrosiveweatherable coatings used in marine environments of China.［Methods］ Two artificial accelerated ageing test procedures suitable for China..s actual marine environments were established referring to thecyclic ageing test procedures outlined in ISO 12944 and Norsok M501. Procedure 1（P1）consists of one cycle：72 h of UV aging（UVA-340）/condensation + 72 h of salt spray + 24 h of high-low temperature alternation. Procedure 2（P2）consists of one cycle：120 h of UV ageing（UVB-313）/condensation + 48 h of salt spray. Verification tests were conducted，with natural weathering exposures in the South China Sea and East China Sea as benchmarks for comparison.［Results］Procedure P1 was suitable for evaluating weatherable coatings with low requirements for the appearance performance but high requirements for corrosion resistance，such as those for offshore platforms. It achieved an accelerationfactor of more than 21 times for anti-corrosion performance. Procedure P1 was suitable for evaluatingcoatings with high requirements for appearance performance，such as ship topside paints. The acceleration rate relative to one-year atmospheric exposure was about 4-6 times，and approximately 7-9. 5 times relative to two-year atmospheric exposure.［Conclusion］ Both cyclic ageing proceduresdemonstrated significant acceleration effect for investigating anticorrosive weatherable coating systems.However，the appropriate test procedure should be selected according to the specific application scenario.
