摘　　要：FPSO处于恶劣的海洋环境中,无论是船体还是上部模块腐蚀都非常严重。针对不同的腐蚀环境采取不同的腐蚀防护措施。对于FPSO船体的防腐措施一般是船体水线以下外表面采用涂层联合阴极保护,水线以上外表面采用涂层防护。对于FPSO上部模块的防腐措施主要包括材料选用、涂料保护以及容器内部的阴极保护。几种防腐措施联合使用,效果最佳。FPSO works in harsh marine environments, the corrosion are very serious whether the hull or topside. Different measures will be adopted against different corrosive FPSO, the outer surface of the hull below the waterline to be protected by cathodic protection combining with coating, the outer surface of the hull above the waterline to be protected by coating. For the topside modules of FPSO, corrosion measures include material selection, paint protection and cathodic protection for iraler surface of vessels. Several anti corrosion measures used together will reach the best results.
