People at Sif

Our people – dedicated, competent and solution-oriented – are our most valuable asset. The older and younger generations at our company share a drive to consistently deliver the best results and remain ahead of the pack. It is this quality, the ‘Sif spirit’, that is our competitive edge in the industry.

We are resourceful enough to do things differently, in the interest of our clients and the market. We firmly believe that an open culture where we support each other, learn from each other and are driven to keep improving is the key to a safe and healthy workplace. We focus on effective collaboration, practical solutions and quality.

Sif offers internal training in the field of rolling, welding and other specific work within our own production lines and there is continuous attention for internal improvements.

We have developed an in-house programme called The Improvement Project (TIP), in which more complex and/or comprehensive ideas for improvement suggested by employees are implemented on a project basis by in-house improvement teams, based on a method developed by Sif. TIP seeks to promote good ideas, connect employees and successfully implement improvements in the workplace.

Sif is known for delivering quality on time. Our entire team can take credit for this, and we invest in their development because they help us make a difference. We have a flexible attitude and know our business. We also give our people the freedom to grow and to show what they can do.

Our core values

Ownership

Another word for commitment
and responsibility. This starts with
clarity about who does what and an open culture in which we approach one another with a focus on solutions
about everyone’s share in the bigger picture.

Focus on results

That’s why we do what we do.
Together, we think carefully about the right focus to ensure that today is better than yesterday.
Sustainable and quantifiable.

Teamwork

The ‘we’ of Sif is super-strong both internally and externally. That is important, as we are a vital component in the wider chain providing wind energy.

Johnsif

John Goessens, Head of Engineering
New solutions in a professional chain. Our profession is very much in development. Both the demand for wind turbines and their scope are increasing with every year that passes, and that has an impact that sends ripples through the chain. It all starts with strong foundations that require as little maintenance as possible and weigh as little as possible.

Andre Derikx Sif dl2 RGB 07

André Derikx, Commercial Manager Pin Piles & Jacket Tubulars
At sea, everything is different; that’s something I have become very aware of since becoming a Commercial Manager for Offshore Steel Structures at Sif. The legs, piles, and pile sleeves that we supply for the jackets for production platforms and distribution stations need to satisfy the most stringent of requirements. And that’s a good thing. After all, when it comes to safety, there can be no compromises.

Bart Theunissen s RGB 02

Bart Theunissen, Manager Production Technology & Innovation
At Sif, we are looking for things to improve every day, whether in our products, processes, or partnerships. Our ambition – to become better, smarter, and more sustainable each day – has been ingrained in all members of staff for a long time. One new development is that I have been coordinating the larger innovations as the manager of innovation & maintenance since the spring of 2018. My job is to connect, encourage, focus, and contribute, because if everyone only works on their own little innovations, then the connections between them and the larger overall success will remain elusive.’

Herman Goverse TK RGB 04

Herman Goverse, Plant Manager
Sif has more than 2000 monopiles to its name. We understand the powerful dynamic between sea, wind, and seabed and we know the properties of our steel inside out,’ explains Herman Goverse. ‘We also know exactly how to make a monopile and a transition piece. This is expertise that can really make a difference when it comes to quality, planning, and budget. By using our practical expertise and experience in the design, we can create added value for our clients.

Michel Kurstjens s RGB 01 2021 03 01 154547 1

Michel Kurstjens, Product Strategy Director
Sif uses new technologies and smart solutions to take the market to the next level and reduce the costs of wind energy. There’s also a need for this: to remain competitive with other energy sources (without the need for subsidies), the costs of the entire chain must be reduced and revenues increased. The Skybox is one of the cost-saving innovations.

Ralph IMG 4485

Ralph Lacroix, Project Manager
On 25 April 2020, Van Oord successfully installed the Slip Joint foundation at the Borssele 5 wind farm using a monopile and transition piece from Sif. It is the first time that an underwater Slip Joint foundation has been installed on an offshore wind turbine on a fully commercial basis anywhere in the world. Sif also supplied a foundation treated with TSA (Thermal Sprayed Aluminium) in a fully automated process – TSA is an alternative coating that protects the pile from corrosion.

Logistic Services Lando s RGB 06

Lando Bax, Operations Manager Logistic Services
There are more than 1,000 transports of monopiles at Maasvlakte 2 every year. In addition, the Sif terminal, with its 600-metre-wide deep-sea quay and favourable location near the estuary, is very suitable as a logistics distribution point for third parties.

Siewerd Hartenhof s RGB 02

Siewerd Hartenhof, Quality Control Engineer
Although steel is strong, it’s also sensitive to rust. We now have six coating halls in Rotterdam, where monopiles are coated in order to extend their lifespan in salt water. This is also where we make the markings for installation. Siewerd Hartenhof has been our Quality Control Engineer for corrosion protection for a year now.
