Analysis for oil and gas

Regulations applying to offshore operations and other high hazard industries require operators to undertake risk assessment and analysis in order to identify measures to protect people against accidents and environmental incidents.

Our analysis services provide you with assurance and better understanding of how to avoid failures in materials, products, systems or structures and mitigate against hazards that pose a risk to both personnel and assets. We do this by identifying and improving understanding of the damage mechanisms, causes of fatigue, behaviour of objects in certain operating conditions and when under stress and root causes of failure. Our technical experts and engineers recommend appropriate remedial actions, verifying safety design and compliance with the latest standards to help reduce risk, down time and inspection costs.

Our services provide a structured basis to identify hazards and to ensure risks have been reduced to appropriate levels in a cost-effective manner:

  • Failure analysis
  • Finite element analysis (FEA)
  • Structural dynamics
  • Flow assurance analysis
  • Data and uncertainty analysis
  • Failure modes and effects analysis (FMEA)
  • Failure modes effects and criticality analysis (FMECA)
  • Failure modes, effects, and diagnostic analysis (FMEDA)
  • Dimensioning accidental loads (DAL) analysis
  • Cryogenic spill analysis for liquefied natural gas (LNG) production and storage facilities such as:
    • liquefaction plants
    • regasification plants
    • their floating counterparts (floating liquefied natural gas (FLNGs), floating storage regasification units (FSRUs) and floating storage units (FSUs))
    • LNG transport facilities such as seagoing tankers, road and rail tankers.
  • An initial cryogenic risk analysis (ICRA): a high level approach running coarse integral methods to estimate the cryogenic hazard zones for the asset and safety critical elements.
  • An advanced cryogenic risk analysis (ACRA): A detailed 3D method that uses 3D numerical methods to estimate heat transfer rates from the cryogenic fluid to the structure (CFD), assess the thermo-mechanical performance of the structure (FEM), and optimise the cryogenic spill protection.
  • A hybrid approach combining the ICRA and the ACRA methods


  • Improved understanding of equipment failure reasons and preventions
  • Understanding of the relationship between process conditions and damage to equipment
  • Reduce inspection costs
  • Reduce risk of failures and downtime
  • Material selection, fabrication control and process monitoring system improvements
  • More effective in-service monitoring and inspection procedures
  • Predictive maintenance
  • Reduced lifecycle costs and operational expense (OPEX) and capital expenditure (CAPEX) optimisation
  • Safely operate beyond original design life
  • Increase safety and reliability
  • Avoid future equipment failures by developing modified inspection plans or by changing equipment design
  • Avoid time and cost consuming design changes at a late stage in the development
  • Make more informed decisions regarding materials and/or equipment operations
  • Improve understanding of an object behaviour under normal or upset operating conditions
  • Make accurate predictions relating to mechanical behaviour of component items under different load conditions
