Electrical, Control Systems and Instrumentation

More recently, we now use AFT Fathom and Arrow, a fluid dynamic simulation tool used to calculate pressure drop and flow distribution in gas piping and ducting systems. We also use Honeywell Forge Process Simulation also known as UniSim Design, a multi-purpose process simulation solution for process design, simulation, safety studies, operations monitoring and debottlenecking, digital twins, process optimisation and business planning.

Our electrical engineering consulting team provide professional electrical engineering services, with specialist expertise in power generation and distribution systems. Typical of our full-service portfolio, this includes specialist consultancy services and studies, feasibility, and detailed design through to procurement, installation supervision, and commissioning.

Mechanical, Piping, Vessel and Stress

With our experience in design consultancy, we are well aware of the multiple targets a designer has to meet during the development process. We have a proven track record in providing efficient and practical solutions to optimise any design with respect to crucial criteria such as strength, reliability, simplicity, weight and cost.

With our background in CAD modelling as the foundation, we have over 20 years of experience in stress analysis and FEA modelling.

Call Our Team

Within our piping, vessel and stress departments we utilise industry standard software packages in delivering solutions and analysing problems:

Static Stress
Fatigue and Life Prediction
Pressure Vessel Design
Pipework Stressing
Steel Structures
Composite Materials
Contact Situations
Dynamic Analysis
Vibration and Resonance
Shock and Impact
Seismic Loads
Non-Linear Stress
Drop Test Simulation
Snap-Fit Assemblies

Civil and Structural Design

Whether you’re looking for a 50m high process tower or a 15m deep sheet piled temporary works pit, we have the skills you need. OLG’s expertise ranges from complex moving structures to the smallest of car parks and everything in between.

In the centre of London or in the middle of the North Sea, our engineers have the experience and understanding to complete your project. With everything from the technicalities of the initial design solution to the logistics of the final build, we will ensure it meets your end user requirements.

We ensure the continued professional development of all our team from our apprentices to our Chartered Engineers and we utilise the tools to ensure that we can design efficiently and effectively whilst adding value.

We utilise the full Autodesk AEC collection, from Civils 3D and Revit on our building and civils work to Advanced Steel for our structural modelling and fabrication detailing. Using Tekla Building Designer, StaadPro and Tedds amongst numerous other design and analysis packages, OLG Engineering design to various levels of detail from concept and FEED through to construction detail, but we will always step back and if required undertake some basic manual checks from first principles.

Guiding You Through Your Project

That understanding of the required level of detail transfers into our fully federated inter-discipline models, we can walk our clients through their project every step of the way. But we don’t just rely on digital engineering, with our co-ordinated laser scans, we undertake basic checks using our experience, blending modern technology with good old-fashioned engineering.

We will walk the project with all stakeholders, enabling the design to become a fully collaborative effort, so we can design exactly what you need. This might be something you didn’t initially consider which is why we look at every project with a fresh perspective rather than trying to copy previous solutions.

We can undertake the Principal Designer role to cover CDM Regulations, undertake structural inspections or help get you through planning and building control. If it involves Civil and Structural engineering, anywhere, we have it covered for you.
