How we are governed

Safety and Reliability Group Board

The Group works across all industry sectors covering the topics of Safety Regulations, Reliability & Performance, Assessment & Maintenance as well as Human Factors.

Each representative on the Board has a designated role and is responsible for executing any duties or actions relating to reporting on technical activities, links with industry, academia, government, defence, not to mention how it communicates with regions and areas.

The SRG Board members include company directors, distinguished professors, senior engineers and managers, and consultants, who organise and lead events in response to developments and also in response to incidents where safety and reliability have failed.

SRG are able to invite senior people directly concerned with investigations and review to present to the group.

Pete Stewart - Chair

Professional Engineer, FIMechE, Director at Hydrock NMCL

Taimore Afzal

Throughput – Reliability, Availability and Maintainability (T-RAM) Assurance Manager, Sellafield Ltd. 

Taimore is responsible for policies and procedures within his function across a diverse company portfolio.  He has designed and implemented Sellafield Ltd’s T-RAM Case; this is a tool that assures the performance of assets.  He is also responsible for guidance, training and mentoring of reliability engineers and the provision of specialist support to companies within the supply chain, also overseeing collaboration with academia. 

In prior posts he has been the head of the Operations and Maintenance Assurance Team and has been involved in business improvements, modelling and simulation.  Current interests are reliability in asset management, condition monitoring of novel equipment and performance based commissioning.

John Andrews

Royal Academy of Engineering and Network Rail, Professor of Asset Management in the Nottingham Transport Engineering Centre (NTEC), University of Nottingham.

Director of the Centre for Risk and Reliability Engineering.

Prior to this John worked for 20 years at Loughborough University where his final post was Professor of Systems Risk and Reliability. The prime focus of his research has been on the development of models to predict the system performance in terms of that of their components. This accounts for the degradation of the components and the effects of maintenance, inspection and renewal.

In 2005, John founded the Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability of which he  is the Editor-in-Chief. He is also a member of the editorial boards for six other international journals including the Journal of Rail and Rapid Transit.

John has over 200 publications in the field of risk, reliability and maintainability engineering. He is a member of the Safety and Reliability Group of the IMechE, the Advisory Group for Railway Research and Innovation (AGRRI) and Chairs the ESRA (European Safety and Reliability Association) Technical Committee on Mathematical Models in Reliability and Safety.

Vaughan Cole

Former H M Principal Specialist Inspector of Health and Safety (Mechanical Engineering) at Health and Safety Executive

Vaughan, over a period of twenty years, held senior mechanical engineering positions in Health and Safety Executive. He was a Petroleum Specialist in HSE, Offshore Division, a Principal Specialist Inspector in Railway Division and a Principal Specialist Inspector in Field Operations Division. Vaughan has assessed safety reports or safety cases in all three Divisions for offshore, rail and COMAH activities.

Prior to joining HSE, he was employed by CEGB for ten years in the assessment of nuclear safety reports or cases. Vaughan’s earlier responsibilities, with British Rail, related to all aspects of railway mechanical and electrical engineering and with BOC, low temperature development projects. In addition, with CEGB, he was employed on coal and oil fired power stations and was responsible for conventional plant quality and timely delivery at contractors works.

Rhys David

Richard Denning

Principal Reliability Engineer for the Ministry of Defence

Richard is responsible for all policy and standards on reliability across the MOD.

In prior posts he has been intensively involved in setting reliability requirements and assessing the achievement of requirements for naval weapon systems and for major platforms. He has produced numerous papers on various aspects of Defence Reliability and has a particular interested in modelling the Reliability characteristics of complex multi-function platforms and the use of the Reliability Case as a tool to ensure Reliability of assets. He is past Chairman and President of the Safety and Reliability Society (SaRS) and is currently editor of the SaRS Journal.

Nicola Stacey

Facilitator, manager, creator at HSE's Risk Education Network

Nicola originally studied electronic and electrical engineering at the University of Birmingham. Her final year project involved computer modelling of rail traction regenerative braking and building power electronic circuits to validate the model. To do this she taught herself the C programming language and introduced it to HSL programmers when she joined in 1986.

She has since held a range of posts spending six years developing software for data display and analysis for bespoke measuring instruments and risk assessment tools. She then spent a year working in the field of ergonomics during which time she was part of a multi-disciplinary team that evaluated teaching pendants for robots and another that carried out an investigation into passenger falls from railway trains. Since 1993 she has specialised in risk, in 1995 successfully completing a part-time MSc in Process Safety and Loss Prevention from the University of Sheffield.

Nicola became technical lead for risk communication and management in the Human Sciences Unit three years ago. Her particular area of interest is integrating health and safety risk concepts into undergraduate engineering courses, publishing several conference papers in this field and being awarded an honorary visiting lectureship at the University of Liverpool in 2007.

Robert Wilson

Bob Wilson is a Chartered Mechanical Engineer having served an apprenticeship covering both mechanical and electrical engineering. He was enrolled as a Member of the IMechE in 1971 and a Member of the Chartered Management Institute (formerly BIM/IIM) 1986/7.

His engineering career has included research and development, design, production, application.

Prior to retirement in 2004, he was a Senior R&M Engineer within the Defence Logistics Organisation of the UK MoD. He supported the introduction of the reliability case and also pioneered root cause analysis as part of the MoD reliability tool kit. He is now a general consultant operating under the business name of Tridiam Services including accident investigation and similar activities relating to Safety and Reliability.
