Abstract The modernization of cathodic protection system of the Baltic Beta platform legs is described. It was that the sacrificial anodes cone-shaped groups were to be placed on the seabed at a depth of 80 m. The measurements results of cathodic protection effectiveness during its ten-years operation are presented. The effectiveness was assessed based on the potential value along the entire length of the legs from the sea surface to the seabed. The gained experience indicates that use of sacrificial anode systems mounted on the seabed can be an effective form of cathodic protection of offshore platforms legs. It is basically the only means of anticorrosion protection in case of a platform not able to leave its location for renovation works in a shipyard.

生产钻机支腿的现代化阴极保护系统 - 十年服务期间的评估

摘要 描述了波罗的海 Beta 平台腿阴极保护系统的现代化改造。是将牺牲阳极锥形组放置在80 m深度的海床上。给出了其十年运行期间阴极保护有效性的测量结果。有效性是根据沿从海面到海床的腿的整个长度的潜在值来评估的。获得的经验表明，使用安装在海床上的牺牲阳极系统可以成为海上平台腿阴极保护的有效形式。如果平台无法离开其位置在造船厂进行翻新工程，它基本上是唯一的防腐保护手段。
