For risk assessment, our ReliaSoft reliability engineering toolkit is used extensively within Oil & Gas to systematically and efficiently undertake life data analysis (Weibull), Root Cause Analysis (RCA), FMEA/FMECA and Reliability Block Diagram (RBDs) & Fault Tree Analysis (FTA) among other tasks. Typical applications include:
- Rank assets based on potential risk to identify critical items
- Model system reliability and availability to identify areas of improvement and increase operational productivity
- Optimise maintenance plans using reliability centered maintenance (RCM) and/or risk based inspection (RBI) principles
- Reduce overhead costs and unscheduled downtime
- Minimise future costs by focusing maintenance resources on assets with the highest potential risk
With our support, ReliaSoft can be an integral component of a Asset Health Management strategy to meet the demands of ISO 55000, while also facilitating safety-related actitivites. Closely related to Chemical & Process, our technical safety team has a 20 year history undertaking HAZOP/HAZID/HAZAN chairing, LOPA and SIL assessment & verification and related qualitative & quantitative risk assessment (QRA) activities. In conjunction with our simulation expertise, we also can undertake Consequence Analysis.
Finite element analysis (FEA) is an invaluable technique for determining safety factors against structural and fatigue failures. We have undertaken hundreds of structural analysis projects for oil & gas related equipment and infrastructure including:
- Linear & non-linear stress & thermal simulation
- Dynamic analysis, including natural Frequency,shock Spectrum, time history & PSD loading
- Stress and fatigue assessment: to relevant DNV, ASME, ANSI ,API & PD5500 codes
Much of this work has served to demonstrate the benefits to our clients of using ANSYS, widely recognised as one of the most capable and popular simulation systems for oil & gas applications. We have undertaken many technology transfer projects, supplying appropriate software and on-going training & support services to all sizes of company, from multinational equipment suppliers to SMEs and consultants.
Our PLAXIS geotechnical FEA software has been deployed for demanding soil-related applications, including stability and settlement analysis, suction anchor & seismic assessment, and reservoir & wellbore scale analysis of borehole stability or reservoir depletion.
Computational fluid dynamics (CFD) simulation is also widely used for optimising throughput while improving reliability. We have supplied both ANSYS CFD software and consulting solutions for upstream and downstream operations. Typical applications include separators, valves, elbows, seals, downhole tools, pigging, coupling and LNG handling, involving pressure-flow characterisation, mixing, cavitation, multi-phase and fluid-structure interaction.
For system level fluid modelling, Flownex is used across the entire supply chain to analyse and optimise plant design and existing infrastructure to maximise potential outputs. Diverse application areas include:
- Pipeline Transportation
- Pumping & Compression
- Heat Transfer Equipment
- Fire Protection
- Blowout Preventer
- Drilling Mud Circulation
- Gas Liquefaction
- SCADA Systems & Control
We are members of Achilles FPAL and NOF Energy.
