This paper discusses and evaluates the data collected from structural detail survey of twelve typical families found on various ship types. The fifty ship survey included seven ship types. Engineers in the Hull Technical Department of Newport News Shipbuilding conducted the survey which was under the sponsorship of the Ship Structures Committee by means of a Naval Sea Systems Command contract. The families surveyed were beam brackets, tripping brackets, non-tight collars, tight collars, gunwale connections, knife edge crossings, miscellaneous cutouts, clearance cuts, deck cutouts, stanchion ends, stiffeners ends, and panel stiffeners. Sketches and pictures depict the 553 observed variations in structural configuration which evolved into fifty-six family groups. The data are synthesized by summarizing the observed data according to family groups and by normalizing the data and summarizing it by ship type. During the survey, 490,210 details with 3,307 failures were observed. Eight-two percent of the failures were in the cargo space and were predominately located in structure adjacent to the side shell. The remaining 18% were distributed, 10% forward and 8% aft of the cargo spaces. Figures and tables are used to present failure trends and percentages. Feedback data of this type is beneficial to design and repair offices. It provides, in systematic manner, the results of "full scale operational testing" on individaul shipboard components. Data of this type has not, to the authors' knowledge, been available in the past.
