Seaway Heavy Lifting

Seaway Heavy Lifting acted as the offshore installation contractor for the HVAC offshore transformer station serving Trianel’s Borkum West 2 Phase 1, the first wind farm to be connected to the DolWin1 transmission project. Using its heavy-lift vessel Oleg Strashnov, the company carried out a two-day offshore campaign to lift, position and weld the 2,400-tonne topside onto its pre-installed foundation in the German North Sea. This work formed part of the construction phase of the DolWin1 grid connection chain, delivering the offshore substation that collects power from the wind farm for onward transmission into the DolWin1 HVDC system.
