International Ship Structure Symposium '84

Arlington, Va. October 15-16 The International Ship Structure Symposium '84 (SSS 84) will be held October 15-16 at the Sheraton National Hotel in Arlington, Va. Sponsored jointly by the interagency Ship Structure Committee and The Society of Naval Architects and Marine Engineers, this is the fourth in a series of symposia sponsored by these two organizations. The first three were the highly successful Ship Structure Symposium in 1975, the Ship Vibration Symposium in 1978, and the Extreme Loads Response Symposium in 1981.

The Ship Structure Committee is the standing U.S. interagency committee charged with conducting a research program to improve the design, materials, and construction of ships and marine structures. The member agencies are the Coast Guard, the Naval Sea Systems Command, the Military Sealift Command, the Maritime Administration, the American Bureau of Shipping, and the Minerals Management Service.

The purpose of SSS 84 is to bring together representatives of the maritime community, including shipowners, operators, builders, designers, researchers, government, and classification societies to discuss recent developments in ship structural design. The program will cover a range of topics including load definition, reliability, ice-capable tankers, ultimate strength, CAD/CAM tools, fracture mechanics, corrosion fatigue, and productivity. In recent years there has been considerable state-of-the-art improvement in these areas, and as always, there remains much to be accomplished. It is timely that the available technology be exposed and discussed in an open forum.

The preregistration fee is $170 per person; registration at the symposium will be $190. This covers admittance to all technical sessions as well as a reception on Sunday evening, October 14, coffee during the technical sessions, luncheons on Monday and Tuesday, and the reception/ banquet on Monday evening. The fee also covers a bound copy of the symposium papers and a second bound volume of the discussions after the symposium.

The main speaker at the banquet will be RADM William M. (Mike) Benkert, USCG (Ret.), who has had and continues to have a colorful career in various positions within the maritime community. SSS 84 is being dedicated to Professor Emeritus J. Harvey Evans, Massachusetts Institute of Technology, who has spent many years teaching, writing on, and researching the structure of ships. He will speak at Monday's luncheon.
