Smulders supplied secondary-steel work and outfitting for the transition pieces on the original Burbo Bank offshore wind farm (90 MW, commissioned 2007). The primary monopile shafts and transition piece structures were supplied by Sif; Smulders' contribution covered secondary steel (boat landings, J-tubes, walkways, davits, and other appurtenances) and assembly/outfitting of the transition pieces — the same scope split that later formalised into the Sif-Smulders JV on Triton Knoll, Dogger Bank (all three phases) and East Anglia TWO. Wikipedia's loose phrasing ('Smulders supplied the WTG foundations') predates that JV branding.
