Technical+risk+%26+reliability+analysis

Today’s systems are growing increasingly complex, with a progressive impact on project risk and production availability. It is therefore imperative to handle the technology’s risks and implementation appropriately. DNV offers a wide range of risk and reliability services to manage both technical and project risk.

Purpose

The purpose of these services is to identify and manage technological risks.

Benefits

There are many risk assessment techniques available to the industry today, but a risk assessment is only as good as the experience of those who make it. DNV’s knowledge of the technologies in the oil and gas industry, combined with first-class risk and reliability methods, ensures that the project’s risks can be managed appropriately.

Key benefits:

  • Wide range of competencies and disciplines that combine system knowledge and state-of-the-art risk and reliability techniques, which results in better quality assessments
  • ‘Lessons learned’ from other parts of the industry
  • Identifies the project’s key risk drivers
  • Predicts failure data even when little historical data is available, or for newly developed technologies.

Our approach

DNV assesses the problem at hand and determines the risk or reliability method that will yield the required result with minimal use of resources. To ensure that all the relevant risks are appropriately evaluated, we typically use a multi-disciplinary team. This combines in-depth knowledge of the technology with the best risk and reliability techniques. Subsequently, we propose appropriate actions to mitigate the identified risks, based on their priority.

Some of the techniques that we utilise:

  • FMECA’s, HAZOP, HAZID
  • Structured What-If Technique (SWIFT)
  • Bow-tie analysis
  • Fault tree, and event analysis
  • RAM analysis
  • Structural reliability analysis
  • Fire and explosion simulation (probabilistic)
  • Simulations (process, operational, logistical and more)
  • Probabilistic life cycle cost = NPV (Revenue – CAPEX – OPEX – RISKEX)
  • Reliability-based design
  • SIL analysis (IEC 61508 & 61511 and OLF guideline 070).
