Task 2.6: Systems Engineering Based Guidelines and Rules for Designing a 100 MW/20 kV E-Ship Incorporated Into S3D

This report describes the on-going effort to define a process for developing a multi-level, rule-based design specification for naval ship electrical systems that can be implemented in the smart ship system design (S3D) enviroment. A generalized process for designing electric warships proposed by Doerry [1] consists of the following steps:

1. Analyze requirements,
2. Allocate requirements to mission systems,
3. Develop initial Concept of Operations (CONOPS),
4. Assign mission systems to ship zones,
5. Develop derived requirements for ship systems,
6. Develop distributed system architectures,
7. Calculate distributed system component ratings,
8. Synthesize the ship,
9. Evaluate total ship mission effectiveness, and
10. Iterate until total ship mission effectiveness requirements are met.

The principal focus of the study performed under this project was to provide the ship architect with information and tools for completing steps 1 and 5 for the design of the baseline MVDC ship electrical system. The section that follows describes the process of defining the “rules-base” for this ship system. This report details the preliminary work for extracting ship design guidelines and rules from well-known resources. Furthermore, the guidelines and rules extracted through this task will be integrated into the S3D environment to enable applying well-established engineering principles to the automation of design evaluation
