Anastasia Lennon has published several informative articles in the New Bedford Light on the challenges posed by the presence of glauconite on North Atlantic wind leases. The above illustrations explain those challenges and identify where glauconite has been found to date. Per her latest article:
Preliminary geotechnical analysis for New England Wind, an Avangrid project, showed a risk of turbine pile foundation refusal in 50 of nearly 130 turbine locations, or about 40%, according to 2023 records obtained through a Freedom of Information Act request.
The mineral’s behavior poses a “significant risk” to offshore wind development, said BOEM, the federal regulator of offshore wind, in a paper last year.
The potential for foundation problems associated with glauconite and other geotechnical factors are among the reasons why decommissioning financial assurance should be demonstrated in full when turbines and other facilities are installed, not years later.
