Oil and Gas

The engineering issues and risks associated with upstream and downstream operations have resulted in great demand for our simulation, safety and reliability software and services over the past decade. With the current economic challenges, these technologies can support asset extension decisions and reduce on-going development and operational costs.

Structural Analysis (FEA)

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.

Fluid Dynamics (CFD)

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.

System-level fluid modelling can be 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

Risk Assessment

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.

We found that the staff at Wilde Analysis listen and are very adaptable, responding effectively and promptly to modifications that can occur during a project. We feel that we work together as one team rather than a separate company.

Europa Valve Ltd

Fantastic support - I have contacted a few times and have always had the problem solved. Professional, friendly and reliable service! The engineer I dealt with has been of great help!

Monition Ltd

Wilde’s integrated scope of material testing, material modelling and model validation provides an excellent base for our FE analysis, allowing our in-house analysis team to focus on providing high-quality analysis of our products.

Siemens Subsea

We are very satisfied with the CFD consultancy project that Wilde completed for us, and found our contact with them very rewarding. The project deadline was extremely tight so we especially appreciated Wilde’s quick response, and the fact they completed the work to a very high standard even sooner than requested. Having an independent third party such as Wilde to validate our data provided important reassurance for our client.

Dunlop Oil & Marine

MAHLE Industrial Filtration UK Ltd have worked with Wilde on a number of previous occasions where independent specialist knowledge, supported by the use of up-to-date computational techniques, were sought to support designs using conventional design processes.

MAHLE Industrial Filtration UK

This course has illuminated areas of technical risk assessment that were unclear.

GE Oil & Gas

Very good course, first class tutor and good introduction to FEA software.

Score Europe

Very good course. Communicates a huge complex package simply and effectively……A rounded course covering a range of topics, presented by a very knowledgeable tutor.

Technip Umbilical Systems

Having some exposure to ANSYS Mechanical in my current role the mechanical intro course has answered a lot of questions and uncertainties. It has also prompted new questions about potential for many of the encountered features and the prospect of facilitating better engineering analysis.

John Crane

Thanks for your support on this. It’s really beneficial to get a second pair of eyes.

FMC Technologies

The course is excellent I feel confident about going back to work and using ANSYS.


Great to be shown the full applications in the software [Lambda Predict] and how they overlap.

Camcon Technology

The project fully met our defined objectives and gave us exactly what we wanted. I was particularly impressed with the Wilde engineer’s knowledge of materials – not many mechanical engineers would know so much about stress properties but he was very clued up on this. In terms of value for money, I would give Wilde ten out of ten

Pipeline Engineering & Supply Co.

The [ReliaSoft] Weibull++ software is a powerful, practical and easy to use package for life data analysis. Its graphical user interface enables new users to master this tool in a relatively short period of time. I recommend this tool in my organisation.

Chevron Texaco

This project was a new venture for us, and ensuring the safety of the operators using this equipment was our key concern. The combination of clear, precise guidance and specialist technical expertise ....... enabled us to accomplish everything that we required.

GE Oil & Gas

Well executed, gives accurate level of confidence to start running simulations unaided... efficient …required minimal interface, but provided a pragmatic approach & interpretation (of results)

Halliburton (Red Spider Technology)

It was very useful to us to get a feeling for how the seal behaves from before fixing to fixed. We would certainly include this phase for future jobs where we plan to use straight tooling for manufacture.

Crux Products

Wilde have given a first-rate service enabling us to prove and improve critical design features.

Moffat 2000

We’d like to thank you for your help with this project. Getting such concise and helpful information back will ultimately help in our quest to buy the ANSYS software.

Victor Lighting

Wilde provided efficient communication with a cost effective approach within the timescale required to keep the project on target. The final report was delivered to both our client and Lloyds Register for third party approval. The team at Wilde gave excellent back up after the report had been delivered, answering any queries relating to the analysis that was raised by the third party body.

Contitech Oil & Gas

We believe that we have been very well supported by Wilde FEA and have a robust solution in the ANSYS product.

Precision Polymer Engineering

Wilde has always demonstrated a knowledgeable and professional understanding to our needs and have been able to quickly and thoroughly assimilate our requirements, and equally quickly produce the necessary results to support our design process and provide guidance on the solution(s) best suiting our needs commercially and technically.

MAHLE Industrial Filtration UK

Wilde was instrumental in the modifying of our existing design to ensure that performance met the specific & stringent customer requirements on this particular project. Without the modelling capabilities & advice/service provided by Wilde we would not have been able to identify the limitations in our current design in house, nor have been able to implement the required design changes that the CFD process identified as being required.

Northvale Korting

Technical support gave timely well informed help with the problem that I faced, including recommendations for tackling similar situations more effectively in the future.
