Failure Mode Analysis

Definition

Failure mode analysis is a systematic process used to identify and evaluate potential failure modes of a system, component, or process. This analysis helps in understanding how failures can occur, the consequences of those failures, and the likelihood of their occurrence, which is particularly critical in the design of mooring systems for wave and tidal energy devices where reliability and safety are paramount.
