Offshore Construction Start

Offshore construction for TenneT’s BorWin5 grid connection advanced in May 2025 when Allseas’ heavy-lift vessel Pioneering Spirit executed a two-week offshore campaign to transport and install the BorWin epsilon offshore converter platform in the German North Sea. The scope covered transport, installation, piling, and grouting of the 7,500‑tonne jacket and 12,300‑tonne topside, which houses the HVDC equipment that will convert power from offshore wind turbines for transmission to shore; the campaign concluded with the safe set-down of the topside on 18 May and was executed without support vessels.
