CHALLENGE ACCEPTED! Ivormatie magazine - August 2022

2

For Iv, these are primarily technical challenges: how can we obtain our energy sustainably? How can we reuse materials better? How do we reduce industry emissions? These are issues for which new solutions must be devised. We love challenges like these at Iv-Groep and on which we can entirely focus: new technologies that enable us to contribute positively to the world around us. The more complex the issue, the more we can demonstrate our passion for technology.

However, the challenge is not only in the technology. Another critical question is: how will we coordinate it? The amount of work to be done is colossal, while there is a great shortage of professionals to do the job; engineers, installers, welders, etc.

And because of the war in Ukraine, the government intends to

It’s again time for a new edition of Ivormatie, this time with the theme ‘Challenge Accepted’. An appropriate theme for the times in which we live. We are faced with a major challenge: climate change.

A Climate Agreement containing goals to limit global warming has been drawn up, with which much work is to be done if we are to achieve these goals. Furthermore, to intensify this challenge: we are dealing with sky-high inflation and war in Ukraine and have yet to find out what the future holds concerning coronavirus? These uncertainties do not make the challenge any easier, but we must find solutions for the issues presented.

speed up its plans. This challenges us to do our job as efficiently as possible; we can use our time only once. Success requires the best possible cooperation with all involved parties because only together can we achieve the utmost.

In more than 70 years, Iv-Groep has developed into a unique company brimming with skilled, enthusiastic employees with many beautiful, challenging projects. Since the beginning of this year, I have had the honour of leading this magnificent company. Quite a responsibility with all the challenges that lie ahead! But fortunately, I don’t have to do it alone. When I see the enthusiasm and passion our people bring to work with them every day and apply it to solving our clients’ issues, I am confident Iv can look forward to a bright future. I am convinced we can take on any challenge. In other words: Challenge Accepted!

I hope you enjoy reading this edition of Ivormatie.

which means temperature differences must also be taken into account. Five degrees can make a substantial difference with, for example, the length because of shrinking or expansion. So these are the aspects that need to be kept in mind.”

We have realised a gigantic project with a relatively small team. That is very impressive.

But such cases also occur in the welding process.

When welding the jacket, the exterior wall of the process vessel, heat is released, through which minimal deformations can occur. These deformations should be limited as much as possible. Of course, this was considered in the design process, says Marcel. “You can’t be ahead of everything or tackle everything in the preliminary phases. But fortunately, we do have highly skilled people here who can prevent this as much as possible.”

According to both gents, the Shenghong project is one of Escher’s most prestigious projects. “The ‘proof of the pudding’ will be the concluding phase in China. Fortunately, we already tested six units during manufacture, which went well without any problems, so we are confident that all will go well.”

Rob hopes that this project will put Escher back on the map. “We have realised a gigantic project with a relatively small team. That is very impressive. And at the

There is potentially a substantial amount of work for us in and around the North Sea. This patented method will make a significant contribution to the careful dismantling of offshore structures. With regard to the tools and in-house specialist knowledge at Iv-Consult, Luuk is confident there is much to gain, both in the conducting of offshore surveys and the patented decommissioning method. “Decommissioning has only just begun and will continue in the coming years.

WHAT MAKES IV SO SPECIAL? Friendly and open culture

Down to earth

Iv feels like a family business: you can always drop by other colleagues to discuss your ideas. You receive a lot of freedom as well as room for entrepreneurship.

Instead of just following trends, we examine the content critically. We innovate because we really want to contribute to the world of tomorrow.

Unique projects

Work hard, play hard

At Iv we work on projects that challenge us to push the boundaries of what is technically possible.

We like to have fun at Iv, which is why, for example, it has become a tradition to attend the UEFA European Championship and FIFA World Cup.

Diversity From infrastructure to submarines: we are the most diverse engineering company in the Netherlands.

Roadmap Plus: The Roadmap Plus was launched in 2019 to accelerate the realisation of Tata Steel’s (climate) goals and is the company’s roadmap to reduce emissions and nuisance for local residents. The introduction of the dedusting installation and the DeNOx installation forms part of this roadmap. The aim is to complete all projects within the Roadmap Plus by 2023, not in 2030. Only the DeNOx installation will be operational in 2025. In addition to sustainability projects around the Pellet Factory, greening and nuisance-limiting measures are also taking place at the Blast Furnace, the coke plant, the cold rolling mill, the steel factory, and the scrap yard and the sinter plant. Many of the dozens of projects within the roadmap are already underway. The Roadmap Plus is expected to be fully completed in 2025.

Then, from here, and considering the health and safety regulations, you further deliberate the system requirements and (partial) solutions.”
