SOME CONSIDERATIONS OF FRACTURE MECHANICS APPLICATIONS IN SHIPS DESIGN, CONSTRUCTION AND OPERATION

The paper discusses the philosophy of a fatigue and fracture control plan for high performance ships and the use of modified LEFM for shipboard LNG cargo containment systems. Current applications of a fatigue and fracture control plan are discussed. The types of shipboard cargo containment systems designed using the modified LNG approach are described. The paper addresses the need for an integrated life time quality assurance program. Such a program is shown to require a synthesis of materials characterization, structural analysis and nondestructive testing. A service performance feedback loop will assist the designers in continually improving the then governing design criteria. In addition, areas requiring further work and possible further applications for fatigue and fracture analysis are discussed.
