  • Marc MacDonald

    Expert ProfileMarc MacDonald

    Marc Macdonald

    head of clean fuels

    What is your role?

    Over the past eight years I have worked on a wide range of projects, including consultancy, research in our laboratory facilities, calibration and testing of flow meters and other process equipment, and specification, design and upgrade of flow testing facilities. 

    18 months ago, I took on the role of Head of Clean Fuels area within the R&D Department.

    What is your academic/industrial background?

    I have an MEng in Chemical Engineering from the University of Strathclyde and I am a Chartered Engineer with the Institution of Chemical Engineers (IChemE). I completed a 3-month work placement at TÜV SÜD National Engineering Laboratory as part of my degree and started a full-time role after graduating. Since then, my experience has been roughly evenly split between desk- and laboratory-based activities. Most of my calibration and testing experience comes from working with multiphase flow meters, either for factory acceptance testing before deployment, or supporting the manufacturer R&D. our facilities are very flexible, so I’ve also tested valves, sampling systems, compact separators and other process equipment, and worked with challenging fluids including high viscosity emulsions. 

    What was the route of your interest in engineering?

    My favourite subjects at school were maths, chemistry and physics. I felt that they were rigorous and graded objectively, so you always knew where you stood. Chemical Engineering appealed to me because there is a good balance between these disciplines, with a strong focus on real world, practical application.

    What are your main areas of expertise?

    My main area of expertise is fluid mechanics, for liquids, gases and multiphase flows. I have hands-on experience with most flow meter types, and a strong understanding of the various measurement principles employed. 
    I also have expertise in measurement uncertainty, which is one of the most important considerations in my current work in designing new flow facilities and primary standards. My degree background plays a crucial role here when it comes to facility design and specifying equipment such as pumps, heat exchangers, valves, etc.

    What are your current key projects and who are your key clients?

    The Clean Fuels group has ongoing projects focussed on flow measurement of liquified natural gas (LNG), hydrogen and carbon dioxide. 

    My personal focus is on hydrogen flow measurement and developing new primary standards and flow test facilities. I am the technical lead for several European projects funded through the European Metrology Programme for Innovation and Research (EMPIR), including MetroHyVe and NEWGASMET.

    I also designed our hydrogen flow facility for domestic gas meters, which will be used to support some of the ongoing UK hydrogen demonstration projects and the development of new flow meters.

    What most excites/interests you about your role?

    While flow measurement of liquids and gases is already well developed and understood, there are many knowledge gaps when it comes to fluids like hydrogen and carbon dioxide. There is a need for new experimental data, testing infrastructure and standardisation. 

    Addressing these challenges allows me to use all the skills I’ve developed to date in new and interesting ways.

    What future trends do you see developing in your area of work?

    My area is closely linked to the decarbonisation of energy, so there are many technological and policy developments to keep track of. There is already a pressing need for high accuracy flow measurement to support the uptake of hydrogen fuel cell vehicles and hydrogen for gas grid decarbonisation, but there will also be a need to accurately measure carbon dioxide for large scale CCUS operations. 

    We are engaging with industry as much as possible to identify new requirements for high accuracy flow measurement and provide the required facilities for calibration, testing and research.

    The applications that we are currently working on are relatively small scale. This is ideal from a research perspective because we can test the suitability of various measurement technologies at relatively low cost. For larger scale applications, there will be a financial incentive to find the most cost-effective calibration methods, for example calibration with inert gases rather than hydrogen, but this can only done where equivalence has been thoroughly demonstrated and shown to be generally applicable; in some cases it may be that use of the native fluid is required, but again that needs to be backed up by rigorous research.

  • Dr Behzad Nobakht




    What is your current role?

    I am a data scientist at TUV SUD National Engineering Laboratory, currently working on data-driven strategies to develop Condition-Based Monitoring (CBM) solutions for use in industry. I am also responsible for analysing large, complex datasets and identifying meaningful patterns that lead to actionable recommendations for the UK’s national standard for fluid flow and density measurement.

    What is your academic/industrial background?

    I have a PhD in Petroleum engineering at Uncertainty Quantification group led by Prof Mike Christie in Heriot-Watt University. Before that, I completed a research internship at Total E&P Pau, France.

    I have a Master’s degree in Petroleum Engineering from Polytechnic University of Turin and a Bachelor’s degree in Chemical Engineering from Sharif University of Technology.

    What are your main areas of expertise?

    •Data-driven modelling of time-series and sensor data

    •Error modelling of simulation models

    •Temporal/Spatiotemporal patterns encoding

    •Synthetic data generation and application in probabilistic modelling

    •Uncertainty Quantification of simulation and data-driven models 

    •Parallel computing and scalable real-time analytics

    What specific tasks and responsibilities does your job entail?

    •Automation of workflows using machine learning and advanced statistical methods for CBM modelling with realistic uncertainty quantification of model predictions.

    •Applying the latest advances in deep learning to NEL's ongoing data-driven modelling of flow meter calibration and research data to address critical problems in predictive modelling. This includes feature learning, generalisation capability, model selection and uncertainty quantification.

    •Ensuring that the models correctly reflect real world conditions.

    What are your current key projects and who are your key clients?

    With the UK government’s Department of Business, Energy and Industrial Strategy (BEIS) as our key client, the digital services group have been developing data-driven models for the classification of time-series data output by flow meters and their surrounding facilities by using deep learning models. As part of CBM modelling, we are exploring different models, which are able to predict the state of a system for both in-sample and out-of-sample test data. The outputs of this research will help end-users interpret and act upon the complex data sets that modern meters are capable of outputting at high frequencies.

    We have recently developed new methods of determining multiphase flow patterns through data-driven flow regime prediction models.

    What most excites/interests you about your role?

    The combination of both domain expertise and data science is core to our predictive modelling systems. The advantage of working onsite at a laboratory generating its own data allows us to validate our own models. I am able to understand the underlying physics of our problems by using domain-specific hypotheses to enhance data-driven models.

    As a data scientist, it is a great advantage to work on interesting modelling projects in an environment such as TUV SUD National Engineering Laboratory, where knowledge and research can be communicated easily with its flow measurement experts. In the short time I have been with the company, my interest in the field of data science has grown and been encouraged by my colleagues.

    What exciting developments have you seen in the company since you started?

    Since I started my job here, the company has invested in high-quality hardware and has increased our capabilities to undertake greater data science workloads.

    With the new Advanced Multiphase Facility (AMF), we will have access to an immense volume of data that cover further scenarios likely to be encountered by meters in the field. This provides an additional route to improve data-driven models currently created by the Digital Services Group.

  • Dr Norman Glen




    What roles have you played at TÜV SÜD National Engineering Laboratory?

    I have worked on a wide range of projects including heat exchanger fouling, stack emissions monitoring, the application of data reconciliation techniques to flow measurement in pipe networks and the traceable calibration of industrial densitometers, all of which require traceable measurements.  For the past 15 years I have been directly involved with many aspects of the UK National Measurement System (NMS) including formulation and delivery of programmes and projects in support of the NMS, such as the development of the CO2 measurement infrastructure at TÜV SÜD National Engineering Laboratory.  I also support many aspects of TÜV SÜD National Engineering Laboratory's knowledge transfer activities, for example through publications, presentations and webinars.

    Where were you prior to TÜV SÜD National Engineering Laboratory?

    I joined TÜV SÜD National Engineering Laboratory in 1983, after doing a PhD with Glasgow University, supported by TÜV SÜD National Engineering Laboratory, on the measurement and modelling of thermophysical properties of fluids at elevated temperatures and pressures.

    What is your academic background?

    I have a BSc (2.1) in Chemical Physics (Glasgow University, 1980) and a PhD ("viscosity coefficient measurement at elevated pressure", Glasgow University, 1985).

    What are you main area(s) of expertise?

    Thermophysical properties of fluids
    Measurement uncertainty
    Heat exchanger fouling
    Industrial water use

    What are your current key projects and main clients?

    I am heavily involved with two current Flow Programme projects: flow measurement infrastructure for high pressure injection systems, and infrastructure to support the transition to cleaner fuels, both of which make use of my expertise in thermophysical properties of fluids.  I  am also the technical lead for our Industrial Densitometer Calibration Service, which involves interaction with a wide range of operators and regulators including OGA and NPD.

    What excites/interests you about working at TÜV SÜD National Engineering Laboratory?

    The range of topics I get involved with, the colleagues I work with and the clients I interact with.

    What future trends do you see developing?

    Two thoughts:
    The hydrogen economy - hydrogen as an energy vector (use of renewable energy to generate hydrogen, thus providing storage of energy generated from wind, solar tidal).  Although there are numerous demonstration schemes already in action, the true impact won't be felt until there is large-scale role-out, but it will affect electricity generation and storage, transportation and industrial and domestic energy consumption very significantly, hence why TÜV SÜD National Engineering Laboratory is becoming involved with hydrogen metrology.

    The IoT - although it is already a very widely-used term, the development of small, cheap, inter-connected sensors will transform many data measurement and processing application, including those in the flow metrology area.


  • Dr Ming Yang

    Ming YangExpert Profile

    Dr Ming Yang

    Principal Consultant

    What is your role?

    As a Principal Consultant, my role is predominantly looking after our existing produced water activities which I have established over the past 20 years. These activities include: event organisation, the Produced Water Club, training, JIPs, testing, consultancy and student projects. On top of that, I develop business in the produced water area by initiating new JIPs and extending existing activities to geographically new locations.  

    What is your academic/industrial background?

    I completed a BSc in Chemical Engineering in 1986 at South China University of Technology in Guang Zhou, China. In the 1980s, China was opening up to the rest of the world and very few people had the opportunity to study abroad. I was one of the lucky ones. I then studied for a MSc and PhD in Chemical Engineering at the University of Manchester Institute of Science and Technology (UMIST).

    What was the root of your interest in engineering?

    Studying chemical engineering was never planned. After all, admission to Universities was only re-introduced in China in 1977. In 1982, when I went to South China University of Technology, only a very small fraction of students finishing secondary schools could go on to study in the Universities. It was by chance that I went to study chemical engineering and got into the discipline of engineering.

    Where were you prior to joining the company?

    Before I joined in January 1998, I worked at Heriot-Watt University as a process engineer from 1991 to 1995 and as a research associate at UMIST from 1995 to 1997. I worked on several large research projects, all focused on produced water characterisation, separation and reinjection. The work experience at both universities got me interested in working for the oil and gas industry and shaped my career.

    What are your main areas of expertise?

    My main areas of expertise include: produced water treatment, handling and management; Oil-in-water measurement; and multiphase separation.

    I have been technically responsible for over 30 international conferences, initiated and run 8 Joint Industry Projects (JIPs). One of which resulted in the development and issuing of the UK and OSPAR wide guidance on produced water sampling and oil in produced water measurement. On the subject of oil in produced water measurement, I have written a book chapter and ran a training course.

    What are your current key projects and who are your key clients?

    I am currently working on various key projects:

    • Produced Water Club: running the Club since 2000 with over 100 organisations once being a part.
    • Produced Water Workshops / Conferences: over 30 such events have been organised in the UK, Middle East, Asia and the USA.
    • JIP – Making Online (OiW) Analysers for Reporting (MOAR): This project was launched last year and currently supported by four oil companies and one government regulator. Two more operators are in the process of joining. The project commenced in October 2019 and is still ongoing. The ultimate aim of the project is to make the use of online oil-in-water analysers common practice for reporting the discharge of produced water offshore (from manned, unmanned and subsea installations)
    • Consultancy: Two consultancy projects are on going. One is assisting an operator association to test online oil-in-water monitors specifically for applications in the heavy oil industry and the other is helping an organisation in Brazil in developing correlations between laboratory-based oil-in-water measurement methods. I am also expecting to start a project shortly to assist a national oil company in understanding how oil sheens are formed, detected and what environmental impact oil sheens may cause and how to mitigate them.

    My key clients include regulators, operators and service providers from the oil and gas industry.

    What most excites/interests you about working at TÜV SÜD National Engineering Laboratory?

    I have the support from the organisation to develop business and see it grow. With activities on produced water now covering event organisations, Club, training, JIP, testing and consultancy, we are constantly engaged with organisations from around the globe. Over the years, I have had the opportunity to conduct work in various countries in Asia, Europe, South and North of America and the Middle East, which is always exciting and interesting. COVID-19 has changed the world upside down, and had a huge impact on travelling, but with modern technology, we are able to conduct most activities without having to travel.

    What future trends do you see developing/will you be looking at in your area of work?

    Whilst there is a significant emphasis in developing cleaner energy, oil and gas are here to stay for the foreseeable future even with COVID-19. Having said that, there are several trends emerging, including:

    For the North Sea, oil and gas production is declining, major oil companies will continue to shift their emphasis by diversifying their investments and interests elsewhere, providing new opportunities for independent operators. Cost control and technology development will be key in producing the remaining oil reserves in the basin in particular with a low oil price environment. How well produced water is managed in the North Sea will play a vitally important role.

    Shale oil and gas production continues to flourish in North and South America. Water management, including flowback water and produced water, is critically important for the sector. Treatment and re-use will be increasingly needed. In Europe and UK, shale gas and oil exploration and production are significantly behind. Concerns of local communities and impact to the environment have made it very hard to advance the sector.

    In Brazil, oil production continues to break records with an increasing output from pre-salt fields. However, a recent change in regulatory requirements surrounding organic acids and other components means that meeting produced water discharge standards has become increasingly a challenge.

    Overall, a combination of tightened regulatory requirements and increasing water production together with the need to use chemically enhanced oil recovery, and a shift towards deep-sea production of heavy oil, means that management of produced water is becoming ever more important.

    For oil and gas production, produced water is inevitable; if there is no water, there is no oil! TÜV SÜD National Engineering Laboratory is well placed to consolidate its position to provide expertise and research to support operators with produced water measurement and management. 

  • Dr Chris Mills

    Chris MillsExpert Profile

    dr chris mills

    What is your role at TÜV SÜD National Engineering Laboratory?

    I am a consultant engineer, working on both BEIS-funded flow programme research and projects for Oil & Gas operators.

    What is your academic/industrial background?

    I have a degree in Chemical Engineering from the University of Strathclyde and have recently been awarded an engineering doctorate for my research into on laminar-turbulent transitional flow measurements. Since joining TÜV SÜD National Engineering Laboratory 12 years ago, I have also become a chartered Chemical Engineer.

    What was the route of your interest in engineering?

    I was always interested in engineering and science from a young age. As a child, I liked to explore how things worked and particularly enjoyed science and mathematics classes at school. Engineering seemed like a natural fit for those interests.

    What are your main areas of expertise?

    I mostly work in single phase flow measurement with a focus on Coriolis meters. This work is both theoretical and practical, using our extensive flow measurement facilities.

    What are your current key projects and who are your key clients?

    I am currently working on a BEIS-funded Flow Programme project investigating the consistency of pressure effects on Coriolis meters. Over the last few years, I have conducted a significant amount of research to understand these effects and published a Good Practice Guide which is available freely on our website. The next stage of this work is to understand the consistency of these pressure effects; if we take identical meters from the same manufacturer, are the pressure effects consistent? The aim is to build a bank of data which can be used to update the standards for industry.

    I am also working on various consultancy projects for oil and gas operators who are interested in upgrading their existing metering technologies, overwhelmingly to Coriolis meters. Due to my specific areas of expertise, I am ideally placed to help them pick the optimum solutions for their applications.

    What most excites/interests you about working at TÜV SÜD National Engineering Laboratory?

    I really enjoy the variety of different projects I get the chance to work on, for example government-funded or consultancy work. I travel often to conferences, write journal articles and provide training courses to individuals all over the world. I also love the hands-on nature of working at the company; the flow measurement facilities are some of the best in the world. I was heavily involved in the conceptual, design and operation of one of our newer facilities; the Elevated Pressure & Temperature (EPAT) oil flow facility. Getting the opportunity to formulate, design and build a facility really is exciting and one of the benefits of my role.

    What future trends do you see developing in your area of work?

    Condition based calibration is a huge trend developing in meter calibration. Currently, industry can use our Elevated Pressure and Temperature (EPAT) facility to understand pressure and temperature effects. In future, we might have a body of work which details for a specific meter, the pressure and temperature effects that should be expected and the corresponding calibration requirements. This will allow industry to move from calendar-based calibration to smarter solutions such as condition-based calibration, providing greater confidence in extending calibration intervals, ultimately saving the end-user money and increasing confidence.

  • Dr Yanfeng Liang

    What is your current role?

    My role is Mathematician, and I work in the Digital Services Team. An understanding of mathematics and its application is vital across all sectors, particularly with the data-rich environments of industry today. My expertise in data science and mathematical modelling helps to bring a new dimension to our Digital Services Team.

    What is your academic/industrial background?
    I obtained a Bachelor’s degree in Applied Mathematics at the University of Strathclyde. I then completed a PhD, also at the University of Strathclyde, on mathematical modelling in infectious diseases. The focus of this doctoral project was to use mathematical modelling to look at the dynamical behaviour of various infectious diseases. The models developed were used to predict the spread of infection under the influence of different environmental and demographic factors, the effectiveness of preventative measures, and the potential for eradication.

    After completing my PhD, I worked for three years on British Council-funded Postdoctoral research focusing on mathematical modelling on the spread of both the Zika virus and Dengue. I collaborated with researchers in Brazil on the Zika virus. On the Dengue project, I worked in collaboration with governments, academia and industry in Malaysia, analysing the effectiveness of a new control measure in eliminating the number of dengue cases in Malaysia.
    I hold an honorary research associate position at the University of Strathclyde, and I am a Member of the Institute of Mathematics and its Application.

    What are your main areas of expertise?

    My own areas of expertise include:

    • Applied mathematical modelling in real life scenarios.
    • Statistical modelling and data analysis.
    • Machine learning models.
    • Build data-driven models to predict and forecast.
    • Fault diagnosis and condition-based monitoring.

    What are your current key projects and who are your key clients?

    Here at TÜV SÜD National Engineering Laboratory, I am currently working on a BEIS-supported project where sand erosion data is gathered from Coriolis flow meters from different manufacturers. Using modelling techniques, we are able to predict the remaining useful life of flow meters when exposed to certain hours of sand erosion. Using data-driven models, we investigate how each Coriolis meter performs differently, despite being exposed to the same hours of erosion, in addition to predicting which meter is less susceptible to sand erosion.

    I am also working on a BEIS-supported project examining diagnostic data generated from four ultrasonic flow meters from different manufacturers, performing fault diagnosis, and predicting the cause of drifts seen in variables. Using statistical models and machine learning models, this enables us to better understand the performance of the ultrasonic meters and enables condition-based monitoring.

    What most excites/interests you about your role?

    With the sheer volumes of data available in industry today, modelling can be used to find correlations between data that otherwise would be missed. The ability to work with a variety of datasets coming from different flow meters and under different operating conditions means that as a result, different modelling techniques can be applied, and you obtain different, interesting and useful insights. The flexibility in conducting research and improving the performance of models, as well as extending knowledge and apply this in different areas such as life sciences; the ability to use results from models to make an impact in real- life scenarios is extremely satisfying.

    What future trends do you see developing in your area of work?

    As the world is moving towards digitalisation, where data is produced in large volumes and fast speeds, having a good system to store data is simply not enough. More and more, industry will need to use advanced statistical models, along with machine-learning models, to analyse their data, in order to unlock the potential and the benefits that lie within it.

    Along with the advancement in data modelling in flow measurement, a more reliable approach in calibrating equipment, namely condition-based monitoring can be used, which in return will improve the industry’s efficiency by ensuring errors are identify and rectified quickly.

  • Muir Porter

    Expert Profile

    Muir Porter

    Group Manager for Infrastructure

    What is your role?

    I provide support to the operational areas through development and improvement projects, as well as covering asset management and control. This includes overall management of the maintenance function as well as the implementation of the measurement traceability activities. My previous roles include flow testing and calibrations, and the management of the UK Flow Programme contract for BEIS.

    What is your academic/industrial background?

    Following a HND in Marine Engineering at Glasgow Nautical College, I completed a BSc degree in Engineering (Mechanical), and a BSc in Earth Sciences and Pollution Control through the Open University. Previously, I was head of Process Engineering at Booth Welsh technical consulting and led the Scottish office of ABB Engineering Services.

    How did your interest in engineering develop?

    As a child, I was interested in Naval architecture and navigation as my father was at sea. I had envisaged a future in the Merchant Navy, but as the UK fleet declined in the 1980’s, I decided to divert my interest to more general engineering and took up a career in engineering project management.

    What are your main areas of expertise?

    My career has mostly centered around engineering project management and technical consultancy within the process industries. I have worked in process engineering across many industries including pharmaceutical, petrochemical, whisky industry and life sciences.

    A recently completed project involved the design, build and commission of the brand new £16m Advanced Multiphase Facility, at a brownfield site at our East Kilbride campus. The AMF is a large multiphase flow loop operating at up to 143 barg and with a separator 33 m long and 2.4 m in diameter housed in a 1600 m2 building. Currently, my team and I are working on a suite of projects to bring about a major modification to the existing National Flow Measurement Standards facilities. This combines facility redevelopments along with both process automation and data acquisition.

    What most excites/interests you about your role?

    For what appears to be a narrow field (fluid flow metrology), there is actually a very broad range of engineering and science involved. In addition, the field of measurement is not static, with new areas of interest opening up all the time across all industry sectors.

    I also enjoy leading an efficient interdisciplinary team of individuals, working with them to develop a consistent professional approach in their support of continuous improvement, new and emerging technologies and best practice.

    What future trends do you see developing in your area of work?

    Digitisation and software automation development will be a big part of the future of process engineering, especially for the processing of large volumes of test data. Moving forward, all engineers will require to have a broad range of skills, including knowledge of programming and data management. This will require support from colleges and universities to ensure the next generation of engineers have the skills needed to meet the demands of industry for the future. 

  • Dr Gabriele Chinello

    Gabriele ChinelloExpert Profile

    Dr Gabriele Chinello

    Technical Lead for Wet Gas Flow

    What is your role?

    I am the Technical lead of the wet-gas facility at TÜV SÜD National Engineering Laboratory and have responsibility for the integrity and traceability of our instrumentation, the data analysis and uncertainty budget of the facility.  I also carry out research projects and deliver commercial work for our clients.

    What is your academic/industrial background?

    I have a Batchelor’s degree in Energy Engineering and a Master’s degree from the University of Pisa, Italy.  My Master’s degree also included an ERASMUS placement at the Technical University of Delft in the Netherlands, focusing on CFD simulation of stratified flow for oil and gas transportation. I then began a PhD at Glasgow Caledonian University, Scotland, joint funded by TÜV SÜD National Engineering Laboratory and the Energy Technology Partnership.  My research thesis was focused on the use of Venturi tubes for wet gas measurement.

    I joined the business in January 2019.

    How did your interest in engineering develop?

    The main drivers for my education, research and employment have always been curiosity and the search for understanding related to physical and engineering processes.

    What are your main areas of expertise?

    My main area of expertise is fluid mechanics applied to multiphase flows, with special focus on wet-gas flow measurement. This includes also the development of Computational Fluid Dynamic (CFD) simulations and multiphase flow phenomenological models. However, my background is broad and includes also thermodynamics, heat transfer, chemistry and electrical knowledge.

    What are your current key projects and who are your key clients?

    Recent key projects have included; research and development for wet-gas flow measurement with Venturi tubes, advances in the standards for wet-gas flow measurement, and sampling and allocation projects for the Oil and Gas industry.

    What most excites/interests you about your role?

    I enjoy the hands-on nature of my role and working on such a diverse range of projects.  No two days are ever the same.  The facilities at TÜV SÜD National Engineering Laboratory are well-known across the world and the organisation is known for its leading-edge work on flow measurement.  New facilities such as the Advanced Multiphase Facility, demonstrate a commitment to the future of flow measurement and one I am excited to be part of. 

    What future trends do you see developing in your area of work?

    There are a number of key trends developing in the area of wet-gas measurement:

    • The development of wet-gas meters based on a single differential pressure device without the need for radioactive sources and for which the operating principle/correlation is in the public domain (e.g. covered by ISO standards or ISO technical reports).  This should offer continuous measurement of the liquid loading (up to and beyond 0.3 Lockhart-Martinelli value) and the water to liquid ratio.  
    • Proving the meter performance at field conditions, under changing flow rates and fluid properties. In this sense a better understanding of the physical phenomena involved in wet-gas flow measurement is fundamental.
    • Enhanced diagnostic capabilities of wet-gas meters.
    • In its role enabling the energy transition, gas will continue to grow; immediately through LNG, but also with blue hydrogen production via SMR or ATR coupled with CCS - projects already entering FEED stage.Developing better Venturi-based meters has a long-term, future-proofed perspective.


  • Marc Laing


    Marc Laing

    head of Computational Fluid Dynamics (CFD) and Modelling 

    What is your role?

    I am the head of the Computational Fluid Dynamics (CFD) and Modelling group, with my time split between overseeing consultancy projects and work on BEIS-funded flow measurement projects.

    What is your academic/industrial background?

    I have a master’s degree in Chemical & Process Engineering from the University of Strathclyde. Previously I worked in the nuclear industry with the National Nuclear Laboratory & AMEC, I have also worked in the energy sector with Doosan Babcock, specifically in their coal combustion research centre.

    What was the route of your interest in engineering?

    I have always been interested in engineering; even from an early age I enjoyed making things and always had an eye for how something could be made better or more efficient. At school my strengths were the sciences and mathematics, so it seemed to be perfectly suited.

    What are your main areas of expertise?

    I work primarily with Computational Fluid Dynamics to simulate complex problems for clients that would otherwise be dangerous, expensive or possibly even impractical to solve with other methods.
    This covers all areas of flow measurement from single phase to multiphase and virtual flow metering.

    What are your current key projects and who are your key clients?

    My key clients are generally major oil and gas operators from all over the world who are looking to evaluate the performance of their infrastructure to ensure that they are operating efficiently, safely and in a way that minimises their environmental footprint.

    Currently we are working on many different projects, however the most exciting of these is a 3-phase flow simulation of a sub-sea riser, and also a flare gas metering & combustion simulation for a major operator across all their global assets

    I am also involved in a BEIS-funded project through the Industrial Strategy Challenge Fund which is looking at how we can monitor and verify the performance of multiphase flow meters in situ, which is an exciting project and a huge step forward for industry if successful.

    What most excites/interests you about working at TÜV SÜD National Engineering Laboratory?

    I enjoy the variety of projects that I have the opportunity to work on. As I carry out a lot of consultancy work, the opportunity to work on real industry challenges provides a sense of satisfaction knowing that the work you are doing is adding value.
    I also get to travel a lot for work which allows me to see many different parts of the world that you wouldn’t often see.

    What future trends do you see developing in your area of work?

    The cloud is becoming much more prominent, both for providing resources such as high-power computing, and the ability to connect multiple different technologies together to minimise common errors.
    The IoT (internet of things) will also likely play a bigger role, along with digital twin models of major assets, however we are a few years away from this becoming the norm.

    Whilst much of our CFD work has historically been related to O&G, we are increasingly translating this to other sectors such as clean fuels, water and life sciences. CFD is highly transferable between sectors and coupled with our flow measurement specific knowledge, CFD will be highly valuable to these new areas as the organisation diversifies.

    Expert Profile

    Dr Zak Latif

    Technical Lead for TÜV SÜD National Engineering Laboratory’s Advanced Multiphase Facility

    What is your role?

    Over the last five years, I have been heavily involved in all aspects of multiphase flow, erosion effects and produced water. Recently I have taken on the role of Technical Lead of our new Advanced Multiphase Facility, which launched in October 2019.

    What is your academic/industrial background?

    I have recently completed an Engineering Doctorate with Coventry University on ‘Continuous Online Oil-in-Water Measurement for Regulatory Purposes’. I also have a Masters degree in Chemical Engineering from the University of Strathclyde and I am currently working towards chartership with the Institute of Chemical Engineers.

    What was the route of your interest in engineering?

    I always found maths, chemistry and physics the most interesting subjects at school. Chemical engineering seemed to fit my interests perfectly, with a great balance between my favourite subjects.

    What are your main areas of expertise?

    I have expertise in a range of topics, including flow system design, multiphase flow, sand management/erosion, uncertainty and produced water measurement and management.

    What are your current key projects and who are your key clients?

    I am involved in much of the research and testing work carried out at high pressure multiphase conditions in our Advanced Multiphase Facility. The main clients I work with are multiphase/wet gas meter manufacturers and end-users. We also work with universities, meter manufacturers, operators and BEIS on research and Joint Industry Projects (JIPs).

    What most excites/interests you about your role?

    Diversity. Due to the nature of different projects that I work on, I can experience different aspects of engineering, from desk-based uncertainty budgets to hands-on slurry testing. I particularly enjoy the hands-on nature of the role, most recently the commissioning of the new multiphase facility.

    What future trends do you see developing in your area of work?

    There are several key trends I see developing:

    • A move away from laboratory to field calibrations
    • Live uncertainty
    • Higher pressures/temperatures
    • Stricter regulations/environmental
    • Focus on traceability

    In our unique position as the UK’s designated Institute for Flow and Density Measurement, our expertise can feed into all of these aspects.

    Expert Profile

    dr Gordon Lindsay

    head of Digital Services

    What is your role?

    Over the last 10 years, I have been one of the lead design engineers of TÜV SÜD National Engineering Laboratory’s Control and Instrumentation Systems within their fluid flow research laboratories. Recently I have taken on the role of Technical Lead in the Digital Services area within the R&D Department.

    What is your academic/industrial background?

    I have a BEng (Hons) in Electronic and Electrical Engineering from the University of Glasgow and I am a Chartered Engineer with the Institution of Engineering and Technology (IET). I am currently in the final stages of an Engineering Doctorate Research Degree with Coventry University, having recently submitted my thesis ‘Detecting and Correcting Calculated Fluid Density Errors in Coriolis Meters’ for examination.
    Prior to joining the business, I was an electronic engineer at robotics designer Clansman Dynamics Ltd, where I designed control hardware and software for use in robotic manipulator systems used in the forge and foundry industry.

    What was the route of your interest in engineering?

    When I was a child, my parents owned an Amstrad CPC 464 computer. I remember from the age of three, loading the cassettes, playing the games and trying to figure out how it all worked. That led to an interest in physics and sciences at school, particularly electronics and digital logic which fits the way my mind works. I enjoy problem solving and find the hands-on nature of engineering extremely appealing.

    What are your main areas of expertise?

    Control system design, build and commissioning; electronic hardware design; digital network design and implementation; engineering research; and software development and support. My EngD has focused on developing intelligent temperature correction for fluid density calculation in Coriolis technology.

    What are your current key projects and who are your key clients?

    I am Technical Lead for a BEIS-funded research project looking at the effective use of flow meter diagnostics. Our project is looking at developing digital solutions that will deliver data at a resolution that enables useful diagnostic interpretation and more effective decision making.
    I am also currently working on several client projects, each with real commercial applications and the potential to encourage innovation in the industry.

    What most excites/interests you about your role?

    It is a very hands-on job. My work involves everything from wiring individual sensors to commissioning the complex system interlocks required for each of our facilities. In addition, as Technical Lead of a new service and team, there are real opportunities to mould and shape our offering in response to industry needs for the future.
    From a personal perspective, I find that being able to pursue professional development opportunities alongside working on commercial and government research projects make TÜV SÜD National Engineering Laboratory a unique place to develop as an engineer.

    What future trends do you see developing in your area of work?

    As devices become more digital, the volume of ‘big data’ produced from industrial facilities will continue to increase. Developing tools to interpret the historical trends buried within the data to monitor the current condition and performance of meters has led to a new range of Condition-Based Monitoring (CBM) solutions available for industry. However, this is not the end of the story; how do we provide confidence that CBM systems are performing as they should? In our unique position as the holder of the UK Flow Measurement Standard, our expertise can feed into supporting CBM systems in the field, increasing confidence in the outputs of CBM for the benefit of industry.
