NSRP_LOGO.jpg

$17.1 Million in New Cost-Reducing Shipbuilding R&D Projects The Executive Control Board of the National Shipbuilding Research Program (NSRP) has awarded funding for five new research and development projects to continue the program’s mission to reduce the costs associated with U.S. shipbuilding and ship repair. These new projects, valued at approximately $17.1 million in both Navy funding and industry cost share, were among those proposed in response to a May 2011 Research Announcement. The NSRP collaboration periodically funds R&D projects to advance technologies and improve processes to reduce shipbuilding and repair costs for the Navy and the shipbuilding industry. The current project portfolio reflects the program’s strategic focus on:   • Reduction in Total Ownership Cost of ships. • Improved quality in ship construction and/or repair. • Improved energy efficiency and environmental impact in shipyards and ships. A brief description of each of the new projects, with a list of participants and funding information, follows:   SHIP CABLE MANAGEMENT Project Lead: Newport News Shipbuilding Team Members: TechnoSoft Inc.   Objective: To adapt, enhance and customize wiring application software applicable to all ship programs in order to reduce cost and time for validation of cable layout design, creation of wiring and signal schematics, generation of production work
