Cathodic protection (CP) anodes and corrosion coating on two offshore pipelines were damaged during deep water installation. In-situ methods for deep-water inspection and repair of the pipelines` CP and coating systems were developed and used. High-pressure natural gas Pipeline. A design was 5.6 miles of 8.625 in. OD by 0.406 in. W.T. API SL, Grade X-42, seamless line pipe. Pipeline B design was 0.3 miles of similar specification pipe. Both pipelines were mill-coated with 14 mil of fusion-bonded epoxy (FBE) corrosion coating. Girth welds were field-coated with FBE.
