Advancements in Underwater Inspection

reportActive / Technical Report | Accession Number: ADA215926 | Open PDF

Abstract:

This report summarizes the advancement of underwater inspection and nondestructive evaluation capabilities being made in the Structural Integrity Monitoring Program, a joint industry program in the United Kingdom. Inspection techniques are discussed that will advance capabilities in the Marine Inspection program area of the U.S. Coast Guard. For example, the Underwater Survey in Lieu of Dry Dock program, mobile offshore drilling unit MODU underwater hull inspection, tension leg platform TLP inspection and inspection of floating facilities mooring system will benefit from this technology. Inspection Systems discussed are eddy current, AC field measurement, and fiber optics. A manipulator is being developed that will perform inspection with these inspection techniques in deep water without human intervention. Participation in this technology. It provides an insight to the industrys viewpoint through contact with commercial sponsors of the joint industry program. Keywords Robotics. AW
