Fault analysis

Fault analysis is a method of determining the various chains of effects that would cause a system to fail, compromising safety or. The fault tree analysis (fta) was first introduced by bell laboratories and is one of the most widely used methods in system reliability, maintainability and safety analysis it is a deductive procedure used to determine the various combinations of hardware and software failures and human errors.

Fault analysis create fault cut-off lines using hanging wall and footwall trim and inclusion distances unique per side of fault calculate and visualize heave polygons for all faults and horizons in a model. Fault tree analysis is a top-down approach to the identification of process hazards it is touted as one of the best methods for systematically identifying and. The analysis of these types of faults is often simplified by using methods such as symmetrical components. A fault tree diagram is used to conduct fault tree analysis (or fta) fault tree analysis helps determine the cause of failure or test the reliability of a system by stepping through a series of events logically.
