Carderock Division, Naval Surface Warfare Center, Code 623 has been involved in the nondestructive test and evaluation of US Navy surface vessels since the 1960s. In this time, CDNSWC 623 has been involved in the utilization and technical development of many forms of NDE including visual inspection, contact ultrasonics, eddy current inspections, computer- automated ultrasonics, and laser optics. The present laser optic tube inspection system (LOTIS) was developed through a joint venture between NSWCCD 623 and Quest Integrated, Inc. of Kent, WA. CDNSWC 623 is presently involved in the centralization of several fleet- wide NDE practices including boiler inspection devices, contact ultrasonics, eddy current, the ultrasonic tube inspection system, and the LOTIS. These systems all have very diverse ranges of application and have proven to be cost-saving devices when implemented throughout the US Navy.
