North Sea windfarm seabed risk

Highlights

Greenpeace dropped 15 tonnes of boulders on the Norfolk Vanguard windfarm site in the southern North Sea, creating a protest barrier against bottom trawling.
The UK's £1bn public investment in Vanguard West and Vanguard East, part of a £12bn offshore wind agreement, faces possible delays as construction is slated for next year.
RWE is negotiating with Greenpeace to verify boulder placement amid concerns extra clearance or updated seabed surveys could raise costs or delay windfarm construction.

Project site overlaps with protest barrier

As first reported by The Guardian, Greenpeace has dropped about 15 tonnes of boulders on to the sea floor in the southern North Sea, with most of the material landing on the site earmarked for the Norfolk Vanguard project. The campaign group says the barrier is designed to protect harbour porpoises by preventing bottom trawling off the Norfolk coast.

The action takes place days before the prime minister tells the Cop31 summit that the UK will invest £1bn of public money in the Vanguard West and Vanguard East windfarms. The wider offshore scheme is linked to a £12bn agreement with the UK government and is due to begin construction next year.

The Guardian says the developer, German utility RWE, is in talks with Greenpeace to verify the exact placement of the boulders so seabed surveys that began last summer can be updated. The company is also investigating any potential effect on the project buildout and undersea cables.

Construction and fisheries impact in the North Sea

Some of the stones, weighing as much as 2 tonnes each, carry signatures from public figures including Simon Pegg and Benedict Cumberbatch, who support the marine conservation campaign. But the boulders are likely to be removed within months as developers prepare the site for construction activities.

Industrial fishing, including bottom trawling, is also likely to shift away from the construction zone once work begins. Greenpeace co-executive director Will McCallum says claims that the boulders create a serious obstacle are "absurd", arguing that offshore wind developers in the North Sea routinely move much larger naturally occurring rocks before installing infrastructure.

The episode underlines a growing operational tension in the North Sea, where marine conservation efforts, fishing activity and large-scale renewable energy investment increasingly overlap on the same seabed. For developers, the immediate issue is whether extra clearance work or revised surveys add time or cost to a flagship UK offshore wind build.
