The 27 separate design steps are presented in a logical sequence, which allows for iterations and feed-back at the appropriate stages of propeller and hull de- sign and model testing. SSC-292, "Report on Ship Vi- bration Symposium '78," is a sum- mary of the Ship Vibration Sym- posium held in Arlington, Va., in October 1978. It succintly pre- sents the state-of-the-art in ship- board vibration and noise, and of- fers key conclusions and recom- mendations reached at the sym- posium. SSC-293, "Underwater Nonde- structive Testing of Ship Hull Welds," is a state-of-the-art study of underwater inspection tech- niques. Radiography, ultrasonic inspection, and magnetic particle testing are particularly discussed, along with necessary modifica- tions for underwater applications.
