The degree of complexity of Integrated Power Systems (IPS) for All Electric Ships (AESs) points out the need to review the design process from a dependability perspective. This paper suggests the application of dependability concepts and definitions to accomplish to requirements set by recent rules and regulations in the field of threat levels for shipboard electrical equipment. Guidelines about 1) how to properly decompose the IPS into conceptual subsystems and 2) how to apply to analyze them, using the Fault Tree Analysis (FTA) and the Failure Mode and Effect Analysis (FMEA) are presented and discussed. As a case study, the IPS of a new built large AES is chosen.

Abstract
The degree of complexity of Integrated Power Systems (IPS) for All Electric Ships (AESs) points out the need to review the design process from a dependability perspective. This paper suggests the application of dependability concepts and definitions to accomplish to requirements set by recent rules and regulations in the field of threat levels for shipboard electrical equipment. Guidelines about 1) how to properly decompose the IPS into conceptual subsystems and 2) how to apply to analyze them, using the Fault Tree Analysis (FTA) and the Failure Mode and Effect Analysis (FMEA) are presented and discussed. As a case study, the IPS of a new built large AES is chosen.Pubblicazioni consigliate
