Abstract
The cathodic protection anodes and corrosion coating on two (2) 8-inch (203.2 mm) outside diameter (O.D.) offshore pipelines were damaged during deep water (-380 feet, -116 m) installation. In-situ methods for deep water inspection and repair of the pipelines' cathodic protection and coating systems were developed and performed Methods are described in which underwater anode retrofits were performed and friction welding technology was used to re-attach anode leads. Standard procedures for underwater pipeline coating repair and remediation of damaged line pipe are provided
