People at Sif

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.

Our core values

Ownership

We take responsibility. In other words: everyone knows their role, and we hold one another to account when we need to. That way, we can all stay sharp and focused on solutions.

Focus on results

This is what we're all about. Every day, we want to be better than the day before. With lasting and measurable results.

Teamwork

At Sif, our sense of collective is strong, both internally and externally. And that truly matters, as we are an essential link in the wind power chain. By helping one another to achieve a shared higher purpose, we are making the difference.

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.

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.’

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.

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.

Stefan Sturm & Ralph Lacroix

This year Sif started the production of 70 TP-less monopiles for Hollandse Kust Noord, a Van Oord project. The monopiles are scheduled to be ready at the beginning of 2023. Stefan Sturm (Manager Operations Office) and Ralph Lacroix (Project Manager) explain how they translate the customer's wishes into an efficient production process.
