Abstract
Abstract Technologies and methodologies need to be developed to monitor ship hull and structural integrity as US navy and maritime industry designs increasingly rely on lightweight materials such as composites and aluminum for ship structures to meet future high‐speed/high‐performance goals. Wave loadings at high speeds result in pressure fields that challenge local and global structural integrity to a degree not supported by traditional navy or commercial design approaches. There is little generic experience related to maintaining structural performance of lightweight high‐speed ships. This is especially true as they age. There is a fast growing interest in equipping high‐speed vessels with an operational real‐time structural health monitoring system. Currently, there are several US navy research and development programs that contain the development of ship and hull structural health monitoring systems. Examples of such will be given. Previous and current efforts as well as required technologies for health monitoring of ship structures will be reviewed. The importance and the roles of an effective structural health monitoring system throughout the life cycle of a ship are discussed. The continued advancement of pertinent technologies will ultimately enable a comprehensive structural health monitoring system that includes diagnostic methods and prognostic capabilities to proactively manage future ship hull and structures.
