Ship Vibration Symposium '78 OCTOBER 16 - 17, 1978 Sheraton National Hotel, Arlington, VA    The papers presented at the 1978 SSC Symposium highlight some recent SSC research along with other topics that are of great interest to the SSC. An electronic copy of each paper can be searched similar, to the SSC reports, on the Search Reports page or by clicking on the paper title hyper-links on the 1978 SSC symposium Agenda page. The Symposium is jointly sponsored by the interagency Ship Structure Committee and the Hull Structure Committee of The Society of Naval Architects and Marine Engineers. This is the second in a scheduled series of symposia jointly sponsored by these two organizations, following the Ship Structures Symposia in 1975. Ship Vibration Symposium '78 brought together international representatives of the maritime community including ship operators, builders, designers, researchers and governmental and classification bodies, who discussed during an intense two day period all aspects of ship vibration, noise and hull/machinery compatibility problems. The 18 technical papers presented in the Proceedings that were distributed in advance of the Symposium and the accompanying volume containing the printed discussion collectively emphasis the interfaces between hull structure, hydrodynamics, machinery and man. Also, the bound proceedings and discussion serve to document the substantial progress and developments that have occurred in the noise and vibration fields over the past decade. The first U.S. conference on ship vibration was held at Stevens Institute of Technology in 1965. Since that time there has been a dramatic growth in the size of vessels and installed horsepower and appurtenant possible vibration levels. But there also have been significant advances in vibration analyses, model testing techniques and new designs such as highly skewed propellers. It is therefore hoped that participants in the symposium and readers of the Proceedings, especially those individuals in key decision making positions in the design and engineering phase of building new vessels, will have gained a better perspective regarding the state-of-the-art, the problem areas remaining, and the significant technical advances available so that future shipboard vibration, noise and hull/machinery compatibility problems will be minimized or totally avoided.
