TSF, European leader in the manufacture of bolted joints in the wind sector

01 February 2024

Why did you join the MAREWIND project and what’s your role?

TSF is one of the European leaders in the manufacture of bolted joints in the wind sector. Thanks to the collaboration with Lurederra in other regional and national R&D projects, TSF was involved in Marewind for developing fasteners and supply samples during the project.

How is TSF contributing to the European renewable energy targets?

As mentioned above, TSF manufacture specialises in producing fasteners for prominent market players. Our main customers include  SGRE, Enercon or Nordex.

Could you provide more details on the criteria and considerations used in the selection process for the specific wind-power sector references that TSF company intends to coat during the MAREWIND project?

One main connection in a wind turbine is the attachment of the blade to the hub. This junction often involved the use of the so-called T-bolts, where the stud is threaded onto the barrel nut embedded in the blade root. The protrudes stud is then fastened to the hub. During the project, there was the 13 meters demonstrator blade manufacturing and TSF fabricated this union in M20.

How does TSF plan to analyse the coating application process and assess the performance of the coated fastening elements in their facilities?

The coating process is scheduled to be applied in Lurederra/Tecnan. THis particular coating has been previously tested in NSS chamber, yielding exceptional results. TSF plans to develop some other mechanical test for characterisation, which are yet to be defined.

How does TSF plan to assess the overall feasibility of the newly coated elements and ensure that they meet the required properties?

Following different international standards about NSS test, mechanical properties, fasteners… One of the main points is the comparison with the already known coatings and their performance on aggressive environments.

How do you see the future of the MAREWIND project?

Based on the quality and importance of the participating companies, covering a wide spectrum of the wind production ecosystem, I predict results that satisfy the initially set objectives.
