Guidance Notes On Failure Mode and Effects Analysis (FMEA) for Classification/Руководство по классификации отдельных систем методом анализа видов и последствий отказов

Книга на английском языке.
ABS requires clients to develop and submit FMEAs as part of Classification requirements for select systems. For instance, FMEAs are required for achieving many of the special or optional Classification notations such as CDS, ACC, ACCU, R1, RQ, DPS-2, DPS-3, ISQM. This document provides guidance and insight into the development process for FMEAs to comply with ABS Classification rule requirements. The utilization of this guidance will provide tangible benefits as the marine and offshore industry is able to realize the positive results of FMEAs that are developed correctly and managed appropriately throughout the lifecycle of a system.
The information presented herein is intended solely to assist the reader in the methodologies and/or techniques discussed. These Guidance Notes do not and cannot replace the analysis and/or advice of a qualified professional. It is the responsibility of the reader to perform their own assessment and obtain professional advice.
