How we check

Every project is checked by hand against at least two public sources — company newsrooms, regulators, trade press. No commercial databases.

Each card shows its sources and the date we checked them (every project in this set: on or after 2026-10-08). We re-check every month; a project that finishes or is cancelled leaves the tour.

Companies appear as sourced project facts only. Reported risks are shown as reported. The discipline lists are our own inference and say so. The small dots are other projects from public datasets — context, not checked by us.

    Why we watch it

    The largest offshore wind farm under construction in the US, and a live example of political/regulatory risk hitting an in-progress project — a case study for how fast schedules and crew mobilisation can move when a stop-work order lands and lifts within weeks.

    Phase in full, as reported

    installation (approx. 81% complete as of 31 July 2026; 31 turbines installed and 32nd underway; first power to the grid March 2026; two of three offshore substations commissioned)

    Reported risk in full, as reported

    A Bureau of Ocean Energy Management stop-work order (December 2025) halted construction; work resumed in January 2026 after a US District Court preliminary injunction, and Interior let the deadline to appeal lapse (April 2026). Project cost rose by an estimated $228 million because of the stoppage; Dominion's budget now stands at $11.65bn (up from $11.4bn) and completion has slipped to end-2027, citing contingency for weather, vessel maintenance, loadout and extended jacking.

    Why we watch it

    Taiwan's first Round-3.1 offshore wind project to reach financial close, and a clean example of Dutch and Belgian marine contractors splitting scope on the same project (Van Oord on cables, DEME on foundations) — the kind of specialised installation work that draws Dutch offshore crews to Asia-Pacific.

    Phase in full, as reported

    installation (99 pin piles, offshore substation and both export cables complete as of early August 2026; CDWE's installation of the 33 jacket foundations follows; inter-array cables from 2027)

    Who builds it as stated by the sources

    Operator / developerCopenhagen Infrastructure Partners (CIP), developed via Copenhagen Offshore Partners

    • Copenhagen Infrastructure Partners / Copenhagen Offshore Partnersdeveloper
    • Van Oordtransport, installation and burial of 33 inter-array cables (~64 km) using cable-lay vessel Nexus, starting 2027
    • DEME, via its Taiwanese JV CDWEtransport & installation of 33 jacket foundations, pin piles and the offshore substation, from Q1 2026, using vessel Green Jade
    • Jan De Nulinstallation and protection of the two high-voltage export cables (~45 km and ~44 km) with cable-layer Willem de Vlamingh; both pulled into the offshore substation by August 2026

    Key dates as stated by the sources

    Financial close
    March 2025
    Completion target
    Commercial operation scheduled 2027

    Disciplines likely needed our inference
