BARD Offshore 1

BARD Offshore 1 (BO1) is a 400 MW fixed‑bottom offshore wind farm in the German North Sea located roughly 100 km northwest of Borkum. The project is notable as one of Germany’s earliest large commercial offshore schemes and for being the first offshore wind farm to use an HVDC export link (BorWin1) into the German grid. BO1 was conceived and built by BARD with an integrated approach — proprietary tripile foundations and in‑house turbine production — which proved both innovative and problematic. Construction and installation were challenged by delays and technical setbacks: a bespoke installation vessel and specialised components encountered design and delivery problems, and the project experienced significant cost overruns and schedule slippage. The original developer BARD went bankrupt during completion. After commissioning activity in 2013 the farm suffered transmission and harmonics problems related to the HVDC link and custom equipment, causing extended periods off‑grid; over subsequent years a dedicated technical and O&M programme restored availability. Commercially the asset was taken into owner/operator hands by Ocean Breeze Energy (UniCredit era) and later sold to Macquarie/MIRA interests. BO1’s experience became a reference case for early offshore industrialisation — demonstrating the risks of vertically integrated, one‑off technology choices while also showing that operational recovery and asset optimisation can restore value in an otherwise troubled project.
