method and apparatus for data input without the diver control of cathodic protection of a structure immergee in salt water

摘要

DIVERLESS CATHODIC PROTECTION DATA ACQUISITION: Diverless monitoring of cathodic protection of offshore platforms wherein a reference electrode is passed along a guideline in proximity to a portion of the platform subject to corrosion is improved by maintaining the electrode at a fixed distance and radial direction from the taut guideline, as by slideably mounting a fixed distance from a second parallel taut guideline.
