Digital Twins for Life Cycle Management

Seminars 01 December 2022

TWI Workshop: Digital Twins for Life Cycle Management

 


Digital twins have great potential to improve the management of all types of structures. The key to a fully functional digital twin for asset management is two-way communication. The digital twin:

1. Collects data from sensors or measurements.
2. Processes that data via modelling, simulations and data analysis.
3. Sends a decision back to the structure or operator.

This type of digital twin has the potential to result in a step-change in automating the assessment of structural integrity, and for informing decision making for asset management.

TWI experts will present on the potential applications for digital twins for asset management, TWI’s capabilities in NDT and structural health monitoring, finite element analysis and structural integrity assessment. We aim encourage discussion on the suitability of the use of digital twins for asset management.

In the interactive session, we want your views! What challenges do you face when using digital twins for structural integrity applications? Digital twins as an information repository or predictive tool? What other digitalisation/ digital twin challenges do you face? The aim of the session is to make links and develop the scope for future TWI joint industry projects.

Tyler London - Technology Fellow / Section Manager – Numerical Modelling and Optimisation

Tyler London

Technology Fellow / Section Manager – Numerical Modelling and Optimisation

Tyler is responsible for computational engineering activities at TWI: developing mathematical models and applying engineering analysis techniques to support R&D, consultancy, product development, and failure investigation.

Tyler’s main areas of focus are related to manufacturing process simulations, fracture and fatigue assessments, and numerical optimisation. He is a Chartered Engineer, Chartered Mathematician, Chartered Scientist and NAFEMS-certified Professional Simulation Engineer. Tyler supports multiple national and international codes and standards including the UK Nuclear structural integrity code R6 (weld modelling guidelines committee), British Standard 7910 (strain-based design and assessment committee), EN 13094 (FEA committee), and the NAFEMS Working Group on Manufacturing Process Simulation. Tyler has published more than 40 journal articles and conference papers and was part of TWI’s team that received first prize for residual stress predictions in the NIST International AM Benchmark competition.



Graham Edwards - Consultant, Non-Destructive Testing Group

Graham Edwards

Consultant, Non-Destructive Testing Group

Graham Edwards has over 45 years of experience in Non-Destructive Testing (NDT). Along with several other graduates, he started his career in NDT with the Unit Inspection Company, where he received training in all aspects of NDT and weld inspection. In 1973, he was one of the first ultrasonic test technicians to gain CSWIP approval. For the next four years, he worked in the North Sea offshore oil, the French nuclear power and Middle Eastern petrochemical industries. In 1977 he joined Baugh and Weedon Ltd as an applications engineer, and was involved in the development of the award winning ‘Seaprobe’ underwater ultrasonic test equipment. In 1981 he became a lecturer in the School of Applied NDT at The Welding Institute (TWI), before moving over to the NDT Research department in 1986. There, his research projects included NDT of plastics and composites, expert systems, and acceptance criteria in BS5500 for ultrasonic testing. He also set up the specialist site services team. While at TWI, he collaborated with the French Welding Institute on the NDT of fillet welds and was seconded to the Edison Welding Institute in the USA for two years to set up the NDT section there. In 1997 he moved to Plant Integrity (PI) Ltd, a subsidiary of TWI, as a plant assessment engineer, and ran many of the early inspections using the Teletest Long Range Ultrasonic Test (LRUT) system.

After 7 years as an independent consultant in NDT, he moved back to TWI in 2005 and has since managed many collaborative projects in topics ranging from guided wave inspection of aircraft wiring to robotic inspection of mooring chains. He is currently in the Monitoring and Inspection Research section (CSM) at TWI, where he is developing continuous monitoring techniques for quality control during manufacture and structural health in service.

Carol Johnston - Consultant – Fatigue Integrity Management

Carol Johnston

Consultant – Fatigue Integrity Management

Carol joined TWI and the Fatigue Integrity Management section in 2009. She manages a range of projects related to the fatigue strength and structural integrity of welded joints. Her main area of work is on validation fatigue testing of welds using the resonance fatigue testing technique and she is now focussing on how TWI’s experience and expertise can be applied and used in the renewable energy sector.

Ujjwal Bharadwaj - Manager, Asset Life Cycle Management

Ujjwal Bharadwaj

Manager, Asset Life Cycle Management

Ujjwal leads a team of experts developing bespoke decision support approaches and software to enable asset operators make optimum decisions based on a variety of criteria, particularly those leading to measurements of risk and life cycle sustainability. The types of decisions that Ujjwal and his team provide support for include when and where to inspect and how to optimise run, replace, life-extend or decommission decisions; this requires establishing the condition of the asset system, at times requiring the use of data analytics, including machine learning.

Ujjwal has been with TWI since 2005 and is now manager of the Asset Life Cycle Management team in the Asset Integrity Management section at TWI. He is a risk management professional with more than 25 years of experience. He is a Chartered Engineer (CEng), with a Doctor of Engineering (EngD) degree from Loughborough University based on his work on approaches to risk-based life management of offshore structures and equipment. He read for an MSc in Risk Management from the London School of Economics (LSE) and a Bachelor of Engineering (BE) degree in Electrical and Electronics engineering from Mangalore University, India.

Martin Bourton - Principal Project Leader

Martin Bourton

Principal Project Leader

Following graduation from the University of East Anglia in 1987, Martin joined TWI as a project leader developing hardware and software solutions. Since 2014, he has managed a series of technology transfer programmes and collaborative research projects related to welding engineering and structural integrity.
