Hazard and Threat Analysis

Adelard has applied several major hazard analysis techniques on a wide range of projects involving programmable electronic elements. These techniques we have used include:

  • Hazard and Operability Studies (Hazops): we regularly lead and record Hazops in several sectors including rail, defence and civil nuclear. We also conduct security Hazops as part of our security informed safety risk assessment.
  • Fault Tree Analysis (FTA): we regularly undertake FTA and assess FTA performed by others.
  • Event Tree Analysis (ETA): recent experience of ETA includes assisting with the ETA of a command and control system and advising on the ETA of a motorway traffic control system.
  • Failure Mode, Effect and Criticality Analysis (FMECA): Adelard assesses FMECA reports for computer and FPGA-based systems like smart sensors, controllers and condition monitors.
  • Structured What-If Analysis (Swift): this has been applied in air traffic management components and map systems.
  • Cause-Consequence Analysis and Bow-Tie Analysis: these techniques have been used in rail industry assessments.

We also provide training on hazard analysis techniques.
