TWI will be presenting a poster titled “Fatigue Performance of Longitudinal Seam Welds Made by Rapid Weld Electron Beam Welding for Use in Monopiles” supported by Cambridge Vacuum Engineering (CVE) and SSE Renewables at Wind Europe in Bilbao on 6^th April.

The presentation will highlight the potential of electron beam welding to produce significant cost savings in many industries under the Rapid Weld project.

The Rapid Weld project aims to create an industry-approved weld process for offshore wind, which is more productive and sustainable than established methods while reducing energy and material costs significantly.

This will use CVE’s new technology, Ebflow.

Ebflow can reduce the time needed to weld a monopile by 95%, whilst being 94% more energy efficient, resulting in a 98% overall cost reduction – compared to traditional submerged arc welding (SAW) – based on a typical specification of a 60 metre long, 8 metre diameter monopile, with a wall thickness of 80mm.

CVE’s Head of New Energy Applications, Chris Punshon, will be at the event – please get in touch if you’d like to discuss the project in more detail!

For more information, you can view the poster.

Find out more about the event on the organiser’s website.

Chris Punshon, Head of New Energy Applications at Cambridge Vacuum Engineering, will feature on the upcoming episode of Weld Tech Talk on Saturday 30th October 2021 at 17:00 IST.

Hosted by The Indian Institute of Welding, the episode’s title is Local Vacuum Power Beam Welding in Energy Applications.

The presentation will cover CVE’s development of local vacuum electron beam welding and its commercialisation (Ebflow), illustrating practical applications of the process in heavy section structural steels, austenitic stainless steels and high-temperature alloys.

Examples of the current and potential applications will be presented together with evidence of achievable weld quality and properties.

Electron beam (EB) welding is a powerful welding process capable of joining large thicknesses of metallic materials in a single pass, leading to the potential for high productivity combined with exceptional weld quality and minimal distortion.

The development of reduced pressure EB welding, and more recently, reduced pressure laser welding has led to the possibility of deploying the process outside the usual confines of a vacuum chamber using local sealing and pumping.

This local vacuum process variant also permits the delivery of active gas during welding, which leads to the possibility of weld composition modification in autogenous welds.

The presentation will aim to answer any questions received before the event where possible, or you may ask them at the end during the Q&A session.

The presentation will take online via Zoom on Saturday 30th October 2021 at 17:00 IST.

Cambridge Vacuum Engineering secure Offshore Wind Growth Partnership funding for a ground-breaking advanced welding solution to support low-cost offshore wind tower manufacturing.

The Offshore Wind Growth Partnership (OWGP) has awarded funding to Cambridge Vacuum Engineering (CVE) in the 2020 Development Grants Competition for the development of ground-breaking electron beam welding technology, Ebflow. As an industrial partner, Global Energy Group (GEG) will be supporting a trial programme and qualification of the technology for eventual use at their planned tower manufacturing facility.

• OWGP award £300k grant for the development of ground-breaking Ebflow electron beam welding technology
• Industrial partner GEG will provide offshore wind sector expertise and a trials programme to qualify the technology with the aim of implementing it at their planned state-of-the-art tower manufacturing facility at the Port of Nigg in the Highlands of Scotland
• Ebflow has the potential to reduce welding time by 76%, cut electricity usage and reduce carbon emissions by 90%

The OWGP grant will facilitate the deployment of CVE’s welding technology for producing long seam and circumferential seam welds associated with offshore wind tower production.

GEG are advancing their plans to develop a next-generation tower manufacturing facility at the Port of Nigg. Participating in this project as an industry partner provides evidence of a UK route to market in offshore wind, paving the way for the commercial introduction of Ebflow. High-productivity welding is a defining factor in influencing the economics of large-scale serial manufacturing.

Ebflow can be readily transported and operated on-site and applied to significantly larger structures than can be accommodated in a vacuum chamber. Ebflow brings all the advantages of electron beam welding to structures of unlimited size.

The technology is also strongly endorsed by SSE Renewables who are leading the current RapidWeld project in electron beam welding and facilitating a trial on the Dogger Bank Wind Farm, the world’s largest offshore wind farm. If successful, this UK innovation will be a world-leading technology, with substantial benefits to UK energy consumers, UK offshore engineering, the associated offshore wind supply chain and the UK’s high-value jobs market.

In addition to other competitive benefits, the collaborative project between CVE and GEG has the potential to reduce welding times by over 75% while bringing down energy usage and associated carbon emissions by over 90%.

Global Energy Group’s Director of Innovation, Steve Chisholm, commented:

“GEG recognises that it can only maintain a position of international competitiveness through the development and deployment of ground-breaking innovation. The application of electron beam welding to offshore wind tower production is truly transformational and has massive potential to improve productivity, reduce cost and dramatically lower carbon emissions.”

Cambridge Vacuum Engineering’s Managing Director, Bob Nicolson, commented:

“Ebflow is a disruptive technology that has been in development for 10 years. It is a major breakthrough in thick section, large structure welding and it has applications in a wide range of industries. The OWGP grant, in conjunction with the RapidWeld project, has the potential to provide a significant step towards the Offshore Wind Sector Deal’s ambition of increasing the UK content of UK offshore wind farms to 60% by 2030. We are excited about the collaboration with GEG, who have demonstrated willingness to adopt new advanced manufacturing processes and are perfectly positioned to integrate this technology into their newly installed manufacturing set-up.”

OWGP Programme Director, Andy Macdonald, commented:

“OWGP is delighted to be supporting CVE’s development of electron beam welding for offshore wind monopiles and towers. It is essential that UK fabricators have early access to technology that can reduce costs and ensure quality for long-term competitiveness. As well as providing solutions to fabricators, this project will help CVE to develop new markets and increase sales in the offshore wind sector.”

Pennsylvania College of Technology (PCT) recently honoured its donors after a ‘best-ever’ philanthropic year. Amongst the list were Cambridge Vacuum Engineering (CVE), who partnered with Penn College in early 2020, resulting in PCT acquiring a CVE electron beam welding machine.

The event saw Penn College recognise honourees for their unwavering support that ignited a record-setting year for institutional fundraising.

The annual event took place in front of the Penn College Donor Wall, which pays permanent tribute to those whose contributions of gifts, pledges, donations and entrustments of equipment and technology significantly empower students – including CVE who feature under the Heritage Society section.

The recognition is a result of the $2m Welding Expansion Project that added 35,000 sq. ft. of space to the College’s instructional lab, as well as new systems and technologies. The state-of-the-art welding lab features a CVE welding machine – believed to be the only electron beam welder used for instruction in U.S. higher education. Next door to the welder, you can find advanced laser welding and cutting processes (including CNC plasma cutters) and a full lab of automation and robotics.

Principal supporters for the expansion project included Cambridge Vacuum Engineering, BAE Systems, Kuka Robotics Systems, Lincoln Electric and more.

As a result, the College can enrol up to 60 more welding students annually – more than 300 in total. The welding lab was first extended in 2010 but has had to be expanded again due to the programme’s popularity and growing demand for graduates in the industry.

The ability to weld thick sections efficiently is critical to drive widespread deployment of cost-effective solutions to meet low-carbon energy needs. Thick section local vacuum electron beam welding is considered a key enabling technology in the serialised fabrication of micro modular reactors (MMR) and other large tubular structures.

CVE, TWI, and Cammell Laird have been working collaboratively for over three years to produce the UK’s first full-size MMR vessel segment.

Supported by Innovate UK, the EBManPower project has demonstrated a low cost and rapid pressure vessel manufacture solution for thick section vessels for nuclear and other industries, using existing UK logistical and manufacturing capabilities. EBManPower focussed on using CVE’s Ebflow system, deployed at the Cammell Laird’s shipyard in Birkenhead, to demonstrate the viability of cost-effective MMR fabrication.

Electron beam welding has been used for the nuclear and aerospace industries for decades. This is the first time that a commercially available local vacuum EB system has been deployed in an industrial environment.

This project has received funding from Innovate UK, grant agreement: 3534/104220. Innovate UK is part of UK Research and Innovation, a non-departmental public body funded by a grant-in-aid from the UK government.

There will be a demonstration day held at TWI Ltd (10:00-14:30), followed by an optional visit to Cambridge Vacuum Engineering (14:30-17:00) to view the Ebflow system, on the 20th July 2021.

CVE is excited to announce the appointment of Chris Punshon as the Head of New Energy Applications at our head office in Cambridge.

Chris brings a wealth of experience and knowledge from the energy, power and renewables industries, which will be utilised to build on CVE’s existing zero-carbon project portfolio.

Chris’ career in engineering began in 1983, after graduating from the University of Sheffield with an honours degree in Metallurgy B.Met (hons). He then joined TWI Ltd, one of the foremost independent research and technology organisations where he worked for 38 years, starting as a Project Leader and leaving as Industry Group Manager Power and New Energy.

During his career, he has directed many ground-breaking research and development projects relating to welding and joining, material properties, and other advanced technologies; in collaboration with a wide range of clients and partners throughout key industries such as oil and gas, renewable energy and power generation.

With growing numbers of countries committed to achieving net-zero emissions by 2050, new energy applications have never been more important.

As such, Chris’ role will focus on further commercialisation of Ebflow within applications such as offshore wind, pressure vessels (small- and micro-modular reactors SMR and MMRs), as well as hydrogen encapsulation and transportation.

Ebflow is a local vacuum power beam welding technology that brings all the advantages of electron beam and laser welding (productivity, repeatability, accuracy), to the fabrication of large structures of unlimited size, achieving high joint completion rates. Therefore, Chris Punshon will be at the forefront of developing its adoption within zero-carbon, new energy applications.

Chris is also a Chartered Engineer (CEng), a Professional Member of the Institute of Materials, Minerals and Mining (MIMMM), as well as a Fellow of The Welding Institute (FWeldI) – a testament to his experience, reputation, and contribution to the community of welding, joining, and allied technologies.

CVE would like to take this opportunity to welcome Chris to the organisation as we look forward to continuing CVE’s commitment to engineering and innovation together.

The developers of the world’s largest offshore wind farm will carry out the first large-scale pilot of Ebflow for the welding of monopiles, which will reduce welding times by as much as 80%.

CVE’s Ebflow technology is expected to be used at the Dogger Bank A phase of the wind farm, to fabricate welds on offshore wind foundation monopiles, reducing the time it takes to carry out the task from several hours to a matter of minutes.

It will be the first time that reduced pressure electron beam (RPEB) has been used on a large-scale offshore infrastructure project and will take place under a collaborative project named RapidWeld.

The RapidWeld project aims to create an industry-approved weld process for offshore wind, which is more productive and sustainable than established methods while reducing energy and material costs significantly.

The project team comprises of:

• SSE Renewables, a leading developer, owner, and operator of renewable energy across the UK and Ireland
• Sif, a global leading manufacturer of offshore foundations
• TWI, the UK’s foremost welding research establishment
• Cambridge Vacuum Engineering, the designer and manufacturer of Ebflow

Ebflow is a reduced pressure electron beam (RPEB) technology that uses heat generated by a beam of high energy electrons to make a high strength and durable welded steel join, cleanly and efficiently.

Ebflow uses a local vacuum, allowing the system to be readily transported and operated on-site and applied to structures significantly larger than those that can be accommodated in a vacuum chamber.

Ebflow will streamline the fabrication process for offshore wind farms, further increasing the efficiency of large-scale projects and demonstrating increased cost-effectiveness of renewable energy for consumers.

Ebflow will also reduce the carbon emissions associated with the traditional welding methods by 90%.

The RapidWeld project is expected to develop methods that outstrip existing welding technology and reduce the costs of future offshore wind foundation monopiles by up to 20%.

A joint venture between SSE Renewables, Equinor and Eni, SSE Renewables is leading the construction and delivery of Dogger Bank, while Equinor will operate the wind farm on operation. When complete, Dogger Bank will be the largest offshore wind farm in the world.

Steve Wilson, SSE Renewables Project Director for Dogger Bank Wind Farm said:

“This is a ‘first-in-class’ project, establishing this UK innovation as world-leading technology. With monopile type foundations accounting for over 90% of foundations used in UK projects, Ebflow RPEB could realise significant cost savings on future projects.

“These substantial savings will not only benefit the UK offshore engineering industry but could be passed on to UK energy consumers.

“It’s exciting that Ebflow is being used at Dogger Bank – a project which continues to contribute to the UK economy by creating jobs and supporting to the supply chain. No doubt, other offshore projects across the world could ultimately benefit from what the RapidWeld partnership achieves.”

The project has been made possible with a smart grant of £600k from Innovate UK, which is part of the UK Government-backed Research and Innovation organisation.

Sif will be responsible for the fabrication and supply of 190 monopiles and primary steel for the transition pieces, as well as for the marshalling of all foundation components for the first two phases of Dogger Bank Wind Farm.

Chief Operating Officer for Sif, Frank Kevenaar said:

“We see great potential in the Ebflow RPEB welding process for thick section welding. Reduced distortion and elimination of filler material are, amongst others, great advantages. We are very pleased to have the opportunity to contribute to this innovative project that is joining forces and expertise to create new cost-effective production methods.”

Ebflow can reduce the time needed to weld a monopile by 95%, whilst being 94% more energy efficient, resulting in a 98% overall cost reduction – compared to traditional submerged arc welding (SAW) – based on a typical specification of a 60 metre long, 8 metre diameter monopile, with a wall thickness of 80mm.
