At this very moment, the Vole au Vent has installed the final WTGs for the Bligh Bank 2 project of the entire 51 windmills. For this ongoing installation project, we supported Jan De Nul with designs and know-how for seafastening and installation of all WTG components.

TWD assisted Jan De Nul already at an earlier stage during the Bligh Bank 2 OWF installation. In June 2016, their jack-up vessel Vole au Vent set sail with re-used seafastening structures, formerly designed and later on modified by TWD.


The Vole au Vent can transport and install as many as eight sets of the wind turbines per trip. Based on the reuse of six existing seafastening structures, TWD redesigned and performed structural integrity checks to make the existing structures suitable for a different vessel and towers interfaces.

Additionally, TWD designed two more seafastening structures to support two remaining tower components and nacelles. The new tower grillages, were not just a copy of the old re-used versions, but were made suitable for the forthcoming Tahkoluoto project, which includes larger tower diameters.

Fabrication Services

Fabrication Services was offered during fabrication and mobilization to provide additional QA/QC follow-up of the TWD designs and unburden Jan De Nul during these final phases. We optimized the production process and translation between designer and fabricator, by providing site inspections, document reviews and onsite assistance during mobilization.
