摘　　要：压载舱长期处于海水压载和空载的干湿交替状态,环境高温湿热、盐分高、密不通风,极易发生腐蚀。浮式生产储油装置(FPSO)压载舱一旦因腐蚀发生泄漏,将造成严重的经济损失和海洋环境污染。为避免此情况发生,对某油田FPSO压载舱的壁板减薄严重、涂层破损、阳极失效等腐蚀问题给出了治理方案,对于其他压载舱的腐蚀治理亦有一定借鉴意义。The ballast tank is in a state of alternating wet and dry conditions between seawater ballast and empty load for a long time,with high temperature and humidity,high salt content,and poor ventilation,which makes it prone to corrosion.Once the FPSO ballast tank leaks,it will cause serious economic losses and marine environmental pollution.To avoid this situation,this article provides a corrosion treatment scheme for the severe thinning of the wall panels,coating damage,anode failure and other corrosion problems of the ballast tank.It has reference significance for the corrosion treatment work of other FPSO ballast tanks.
