Prof John Strutt retires as Technical Director

Following 10 years in the role, John's retirement leaves a lasting legacy shaping Astrimar's future

Following 10 years in the role, John's retirement leaves a lasting legacy shaping Astrimar's future

John has served as Technical Director since co-founding Astrimar in 2010.  During this time, John has led Astrimar’s technical innovations, as well as sector-wide transformation in subsea reliability.

John’s career started as a materials scientist at the University of Sussex before moving to Cranfield University where he undertook teaching and research across a number of industries, with an increasing focus on oil and gas and in particular the subsea sector. John’s interest in reliability and risk management grew from his work in understanding materials-related failures, becoming internationally recognised as an expert in the field of reliability engineering.

In 1999 John was awarded an industry-sponsored Chair in Reliability Engineering and Risk Management at Cranfield University, where he led research and taught MSc programs in Subsea Engineering and Safety, Risk and Reliability, teaching many who are now today’s key names in the Subsea Industry.

In 1999, John was approached by a major subsea operator looking at how to improve the reliability of subsea equipment, after experiencing painful early life failures in the new “deep water” fields.  This started a 20-year journey in Subsea Reliability, which has transformed the way the industry addresses reliability and resulted in a step-change in the reliability achieved, enabling subsea to remain competitive against other production solutions.

After more than 30 years in academic research and teaching, John retired from University life and joined Boreas Consultants (subsequently Atkins Boreas) in 2005 to lead their Risk and Reliability team before leaving to set up Astrimar in 2010.

John’s early subsea reliability work led to him becoming the Champion and lead author of a new API Recommended Practice (API RP17N) on subsea reliability and technical risk management, which was first published in 2009 and became the common industry-wide language for subsea reliability.  John was also responsible for updating and extending the guidance following the Deepwater Horizon accident, re-issued in 2017.  In 2014, John received a citation from the API Committee on Standardization of Oilfield Equipment and Materials, for his “distinguished and meritorious service and many contributions to programs of the Institute”.

In parallel to this, John was also asked to review work undertaken by the Subsea processing community, using the NASA concept of TRLs as part of technology qualification.  He developed these approaches further and after supporting operators and developers in their application, and providing training through SUT, he championed the creation of the new API recommended practice on Technology Qualification, API RP 17Q, published in 2018.  The use of TRLs has now, as a result, become the common language of new technology qualification in the subsea industry.

In 2010, after the Deepwater Horizon accident, John was requested to join a new BOP reliability task force in Houston to drive a change in culture in the subsea drilling sector to achieve and demonstrate greatly improved BOP reliability, in response to the requirements set out by newly formed BSEE, to enable drilling to re-start in the GoM.  After serving on the team for around 3 years, he was also asked to support a technology qualification programme for a next generation of (20k) subsea BOP.

John has worked with many different operators, engineering contractors and equipment suppliers around the world, driving reliability engineering best practice across the subsea industry, enabling it to deliver step changes in reliability achievement. He has been responsible for developing industry and in-company best practices, training and coaching engineers and champions, such that reliability engineering is now a routine part of design and operations across the industry.  He has also contributed to a wider range of related industry guidance, including Energy Institute guidance documents on Integrity Management and Obsolescence Management

More recently, as Technical Director of Astrimar, John has continued to be a visionary and lead innovation in applying advanced reliability engineering techniques to address current industry challenges. This includes developing state-of-the-art techniques to support data-driven predictive risk-based integrity management, utilising all inspection, monitoring and test data related to equipment condition. Encompassed in Astrimar’s industry-driven, innovative software pRIOriti-AIM, it is used by operators for both Integrity Management and Life Extension assessment. In addition, John has developed the science behind Astrimar’s InnovateUK funded STEM-flow tool to model the reliability of well P&A sealing systems, to support the qualification of new P&A barrier materials, as well as enabling data-driven risk-based P&A design, for optimisation in subsea decommissioning. 

Throughout his distinguished career, John’s passion has been to understand and prevent failures, by incorporating reliability into everyday business. John continues to support Astrimar in an advisory capacity. His passion for reliability and innovation leaves a lasting legacy shaping Astrimar’s future and its role in the wider industry.

Success at SPE Young Professionals - UK Student Paper Contest

Astrimar is delighted to recognise the success of Brian Willis, one of our R&D Engineers, at the recent SPE Event in London.

Astrimar is delighted to recognise the success of Brian Willis, one of our R&D Engineers, at the recent SPE Event in London.

SPE London Section held its 1st Annual UK paper contest with the Young Professional and Student Chapters at London South Bank University on Wednesday 25th September 2019.  The event provided an excellent opportunity for the two chapters to interact, share and learn from each other, while presenting on their chosen topics in front of a panel of examiners and peers.

Astrimar’s R&D Engineer, Brian Willis, won the young professional category for his presentation of a system model for a risk-based approach to well plugging and abandonment (P&A). He offered an overview of the P&A challenges facing operators and technology developers with a focus on the decommissioning in the North Sea. Brian then proposed a system model to represent a well P&A design addressing the potential failure mechanisms of a plug.  He also explained the importance of a risk-based approach when dealing with the uncertainties present in these systems. Following the presentation, the examiners asked questions relating to the technical aspects presented, about new technologies entering the P&A market and broader topics on P&A legislation, regulation and guidance.

Astrimar present at Decom North Sea Networking Breakfast

Astrimar joined other Decom North Sea members to deliver an elevator pitch on our STEM-flow software for prediction of well P&A integrity risk.

Astrimar joined other Decom North Sea members to deliver an elevator pitch on our STEM-flow software for prediction of well P&A integrity risk.

Astrimar’s Brian Willis was delighted to present about our STEM-flow® modelling approach at Decom North Sea’s event at Aberdeen’s Chester Hotel on 21st August 2019.

STEM-flow®, which incorporates a probabilistic modelling approach, is used to evaluate long term well plug integrity to support P&A design and application of new technologies.

The drive to reduce the huge projected costs for North Sea decommissioning is leading many operators to look to new technologies, including new barrier materials (such as bismuth alloys, resins, and thermite) as alternatives to cement. To effectively displace the use of cement, these materials need to demonstrate that they offer at least the same performance as cement plugs, while costing less to deploy. Alignment to industry requirements to achieve a 3000-year plug life is a significant technical challenge.

Astrimar developed the STEM-flow® risk-based plug integrity assessment model, to support this challenge, by evaluating the performance of cement and new barrier materials over time, based on well data and materials test data.  The insight provided by the analysis enables effective P&A design decisions for both current and new barrier materials. 

More information about the event and a copy of Brian’s presentation can be obtained from the Decom North Sea website: https://decomnorthsea.com/events/august-networking-event.

Astrimar to present at 9th SPE Well Abandonment Symposium

Technical director, John Strutt will be presenting with Brian Willis on our STEM-flow model used to evaluate long term well plug integrity for P&A design and new technologies, at the AECC on 26th June.

Technical director, John Strutt will be presenting with Brian Willis on our STEM-flow model used to evaluate long term well plug integrity for P&A design and new technologies, at the AECC on 26th June.

We are delighted to be presenting our STEM-flow model at the 9th SPE Well Abandonment Symposium taking place in Aberdeen on 26th and 27th June 2019 at the AECC. The STEM-flow model, which incorporates a probabilistic modelling approach to assessing long term well plug integrity, is particularly relevant for new P&A technologies and non-standard approaches to P&A design.

Many operators are looking to new technologies (materials and techniques) to reduce the huge projected costs for decommissioning North Sea assets. New materials, such as bismuth alloys, resins, and thermite offer attractive alternatives to cement. To effectively displace the use of cement, these materials will need to demonstrate that they offer at least the same performance as cement plugs, while costing less to deploy. This is extremely challenging to demonstrate, particularly industry requirement to achieve a 3000-year plug life.

Astrimar has developed STEM-flow, a risk-based plug integrity assessment model, to support this challenge by evaluating the performance of cement and new barrier materials over time, based on well data and materials test data.  The insight provided by the analysis enables effective P&A design decisions to be made for current and new barrier materials. 

Astrimar's presentation, titled: "How can new P&A technologies ever demonstrate they are good enough to meet industry requirements?", will examine the impact of uncertainties in barrier material properties and leak rate criteria on the reliability performance and predicted statistical life of plugs using STEM-flow. Comparisons will be made between cement and Bi alloy plugs. The importance of plug material qualification testing and its role in risk-based well P&A and integrity assurance will be discussed.
