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.
