Abstract:

A survey of current Coast Guard inspection techniques used to inspect commercial ships is presented. This is followed by a survey of industry and government agencies to identify current inspection techniques used to inspect large structures. Recommendations are included on ways the Coast Guard could improve the current inspection techniques. In general, it was found that visual inspection was the principal technique used for ship inspections. Ultrasonic thickness gaging is also used extensively to verify plating thicknesses. The current method of inspection appears to be the best judging from what other industries are doing. Improvements in tank lighting for visual inspection or the use of night vision devices show the greatest potential for inspection improvement as reasonable cost. Better access to tank structures is also needed. It is recommended that the Coast Guard consider requiring built-in access provisions for new tankers to reduce the risk of structural problems being missed during inspections
