ABSTRACT:
Apparatus in an offshore fixed structure for monitoring the effectiveness of an under water cathodic protection system. Said system includes a guide cable, both ends of which are adjustably positioned at the structure's upper end. The cable is retained on a turning spool at the structure lower end to define parallel guide segments upon which a carriage is operably mounted. Monitoring instrumentation carried on the carriage is caused to scan the structure, thereby providing a series of readings which report on the effectiveness of the cathodic protection system.
