For inspection, develop guidelines for f~tness-for-purpose assessments; develop new inspection tools and improve existing tools; and quantify the fatigue life of temporary repairs. For communications, develop a cradle-to-grave ship structural integrity database system that includes hull-stress monitoring, inspection, and repair data; develop and promulgate a manual or library, sorted by levels of fatigue strength of predictable standard details for fatigue resistance; educate and train future structural designers at the undergraduate level in fatigue and fracture design methods; and use concurrent engineering in ship design to include designers, owners, operators, fabricators, and surveyors/inspectors in the process.
