摘　　要：吸力锚作为FPSO系泊系统的重要组成部分,关系到整个系泊系统的安全性与可靠性,防腐设计以及建造至关重要。吸力锚的防腐方案采用阴极保护联合涂层防护。阴极保护采用安装牺牲阳极,涂层防护采用涂装水下环氧涂料。无论是阴极保护还是涂层防护都要满足吸力锚的设计寿命。Suction anchors as an important part of the FPSO mooring system, affect security and reliability of the mooring system, corrosion design and construction is critical. The solution of corrosion control adopt cathodic protection in combination with coating protection. Sacrificial anode shall be used for cathodic protection, immersed epoxy coating shall be used for protective coating. Whether cathodic protection or protective coating must meet the design life of suction anchor.
