Offshore Construction Start

In Q1 2026, offshore construction for BorWin6 commenced with the installation of the BorWin kappa converter platform jacket at the project site in the German North Sea (Cluster 7). The 5,461-tonne jacket foundation, fabricated at McDermott's Jebel Ali yard in the UAE, was loaded out by Mammoet in February 2026 and sailed to the installation site. Per Heerema/Mammoet Q1 2026 social media updates (including Hallam Knight's LinkedIn posts ~March 2026), the jacket was successfully installed offshore with pin piles in place, marking the first offshore works at the project site. Topside float-over is expected later in 2026. This is the genuine offshore_construction_start for BorWin6 — distinct from the earlier factory fabrication milestones (first steel cut July 2023, topside staging Jan 2025, jacket loadout Feb 2026) which are recorded as manufacturing_update events.
