In recent years, advances have been made in the application of quantitative fatigue and fracture assessment procedures facilitating safe and cost-effective decisions in design, material specification and maintenance of land vehicles and structures, aircraft, offshore structures, and pipelines.
Several projects sponsored by the Ship Structure Committee (SSC) have demonstrated the applicability of these principles to ship structures. However, their practical implementation has been somewhat limited. In 1998 (Troy, Michigan), 2000 (Houston, Texas), 2001 (Halifax, Nova Scotia), 2004 (Houston, Texas, and London, England), 2005 (Arlington, Virginia, and Athens, Greece), 2006 (Houston, Texas), 2008 (Barcelona, Spain), 2010 (Houston, Texas), and 2011 (Houston, Texas), BMT Fleet Technology Limited, on behalf of the SSC, conducted a short course designed to impart existing knowledge to those engaged in ship structural design and to demonstrate its application through practical examples.

This three-day course begins with a review of the fatigue and fracture problems observed in marine structures and how they have been addressed. This is followed by an introduction to material characterization for in-service defect and condition assessment with explanation of the quantitative procedures for assessing the fatigue and fracture performance. The concepts discussed can be used at the design stage as well as in-service to select materials and size scantlings, to make maintenance and inspection decisions and to assess life extension. Ample opportunities, formal and informal, will be available for discussion among participants and the course leaders.Attendees are encouraged to bring a laptop computer to participate in interactive sample applications of the concepts and approaches discussed, using FlawCheck software provided free of charge by BMT.
This course is geared toward the needs of naval architects, ship superintendents, marine surveyors and engineers responsible for design, material specification, welding, operational safety/risk and for scheduling and implementing maintenance. Senior students engaged in naval architecture studies would also benefit from this course.
