This paper describes an adaptable component level machinery system weight and size estimation tool used in the context of a distributed system architecture framework and ship concept design. The system architecture framework decomposes the system of systems into three intersecting architectures: physical, logical, and operational to describe the spatial and functional relationships of the system together with their operational behavior characteristics. Following an Architecture Flow Optimization (AFO) energy flow analysis based on this framework, vital components are sized based on their energy flow requirements for application in a ship synthesis model (SSM). Previously, components were sized manually or parametrically. This is not workable for assessing many designs in concept exploration and outdated parametric models based on historical data are not sufficiently applicable to new ship designs. The new methodology presented in this paper uses the energy flow analysis, baseline component data, and physical limitations to individually calculate size and weight for each vital component in a ship power and energy system. The methodology allows for new technologies to be quickly and accurately implemented to assess their overall impact on the design. The optimized energy flow analysis combined with the component level data creates a higher fidelity design that can be analyzed to assess the impact of various systems and operational cases on the overall design. This paper describes the SSM, discusses the AFO's contribution, and provides background on the component sizing methodology including the underlying theory, baseline data, energy conversion, and physical assumptions.
