The Tenth Annual IREAPS Technical Symposium, held in August 23-25, 1983 in Boston, Massachusetts, represents one element of the IREAPS program which is designed to provide industry with the opportunity to review new developments in shipyard technology. The Symposium highlighted all aspects of the National Shipbuilding Research Program (NSRP) in that presentations were made by all the panel chairmen of the SNAME Ship Production Committee. The 1983 IREAPS Technical Symposium Proceedings contain the papers presented at the meeting.

The REAPS Program is a U.S. shipbuilding industry/Maritime Administration cooperative effort whose goal is the improvement of shipbuilding productivity through the application of computer aids and production technology. The Seventh Annual REAPS Technical Symposium, held October 14-16, 1980 in Philadelphia, Pennsylvania, represents one element of the REAPS Program which is designed to provide industry with the opportunity to review new developments in shipyard technology. The Symposium this year highlighted all aspects of the National Shipbuilding Research Program (NSRP)* in that presentations were made by all the panel chairmen of the SNAME Ship Production Committee. Appreciation is expressed to the management of Sun Shipbuilding and Dry Dock Co. for allowing symposium registrants to tour their facilities. We are particularly indebted to all the people at Sun who volunteered their time to make these tours so interesting. The 1980 REAPS Technical Symposium Proceedings contain most of the papers presented at the meeting.

The computerized programs for piping system evolution: 1. provided pipe bending data for length, bend angles, roll engles and distance between bends, 2. added fitting, valve, and hanger locations to both bent and straight pipe by match marking and creating pipe details, 3. combined details into assemblies, 4. generated isometric and orthographic drawings, 5. added welding identification and data, 6. extracted and added material information, 7. expanded to include work authorizations, trade work instructions, feed relationships, test boundaries, and serialization, and 8. generated tapes for data transfer to work authorization files and reports for manufacturing and installation.
