The OMAE ' 97 Materials Symposium continues to serve as a major forum for researchers, engineers, manufacturers, and fabricators to share recent advances, discuss problems, and identify challenges associated with materials applications to ensure the economic development and safe operation of the offshore and arctic industries. This symposium includes more than 40 papers that were reviewed by recognized specialists and revised prior to acceptance. These papers discuss recent advances in several areas that are important tor offshore and arctic development and operations with emphasis on underwater welding and repair, effect of welding parameters on joint properties, advances in offshore materials (composites, aluminum and steel), integrity assessment and fracture, welding and properties of stainless and high strength steel pipelines, and fatigue strength and crack growth kinetics. In addition, some papers associated with materials are also included in Ocean Space Utilization Symposium, and in Safety and Reliability Symposium.
