Abstract

The U.S. Navy is currently challenged to develop new ship designs under compressed schedules.

These ship designs must necessarily incorporate emerging technologies for high power energy

conversion in order to enable smaller ship designs with a high degree of electrification and

next generation electrified weapons. One way this challenge is being addressed is through development

of collaborative concurrent design environment that allows for design space exploration

across a wide range of implementation options. The most significant challenge is assurance of

a dependable power and energy service via the shipboard Integrated Power and Energy System

(IPES). The IPES is largely made up of interconnected power conversion and distribution equipment

with allocated functionalities in order to meet demanding Quality of Power, Quality of Service

and Survivability requirements. Feasible IPES implementations must fit within the ship hull

constraints and must not violate limitations on ship displacement. This Thesis applies the theory

of dependability to the use of scalable metamodels for power conversion and distribution equipment

within a collaborative concurrent design environment to enable total ship set-based design

outcomes that result implementable design specifications for procurement of equipment to be used

in the final ship implementation.
