Chemosensor Array for Detecting the Proliferation of Weapons of Mass Destruction

Not Available This proposal will develop a feasible framework for reliability assessment of existing watertight decks and bulkheads of vital spaces and establish reliability levels inherent in present design codes for these structural components. Applied Research Associates, Inc. brings over fifteen years of experience in reliability and risk assessment, and reliability-based design methodology. ARA has teamed with industry partners ABS Americas and Designers & Planners, Inc., who will bring valuable expertise in ship structural analysis and design. In this proposal, we will present innovative and feasible solution strategies for reliability assessment, including: (1) use of a simplified load model with consideration of uncertainty in ship motion, wave action and various sea states as well as hydrostatic pressure, and (2) use of simple and basic element models. The load model proposed will be consistent with damaged stability criteria. Modes of failure will be identified for structural components under flooding conditions. The successful completion of this study will provide a basis for further calibration of the current design codes and development of reliability-based design criteria for these structural boundaries in Phase II. Use of these new criteria will result in a uniform reliability level for the structural components forming vital spaces.
