RISK ASSESSMENT

Micro-structural changes and structural changes of the materials are result of various operating conditions, high stress-strain and temperatures. This is specific for the pressure equipment installed in petrochemical plants and power generation plants.

Manufacturers of the pressure equipment are obliged to verify and approve risk assessments as part of a Conformity Assessment process according the PED Directive 97/23/EC.

During service, risk assessments are necessary when changes are being made to the installation.

The benefits of a risk-based approach to inspection include increase in availability and cost saving, minimum duration of shutdowns, decreasing of the inspection intervals and safety compliance issues.

The type of pressure equipment is relevant for the applied risk assessment method, such as Hazop/Hazan, Fault Tree Analysis (FTA), FMEA, and others.

TSG has great experience in risk assessment consulting and services with key benefits of:

  • Identification of key process parameters affecting degradation rates
  • Identification of potential damage mechanisms
  • Estimating the likelihood of occurrence of the hazard
  • Assessment of proposed process changes that could impact degradation rates
  • Identifying measures and evaluation of effectiveness of inspection activities
