Abstract : Even though fractures in ship structures have been researched for over 40 years the continue to be bulk carriers lost at sea with no trace and unexpected fatigue failure in deep draft tank ships. It has been found on many occasions that failures, while unexpected, could have been prevented had currently known information been used in the design, construction, maintenance, and inspection of the ship. The Ship Structure Committee recognized this situation and requested the Marine Board of the National Research Council to convene a workshop to document the methods and educate the industry. This report includes all elements of the Symposium and Workshop on the Prevention of Fracture in Ship Structures held in March, 1995. It invited background papers were presented covering History and Background, Defining the Problem, and Current Practices in Other Industries. Then a series of technical papers on the state-of-the-art in areas of Design, Fatigue and Fracture, Reliability, Inspection, Loads and Materials and Fabrication were given to have the workshop members enter discussions on a level playing field. The first section of this report are the findings of the workshops with the final recommendations to the industry. The papers presented in the symposium follow that.
