澳门玄机图 updates key BOEM report and OceansMap Portal for Floating Offshore Wind Farms in California

Floating offshore wind in the U.S. is moving rapidly in California. The California Energy Commission has set ambitious targets of , and multiple Floating Offshore Wind Farms (FOWF) must be built to meet this goal.听

As a follow-up to the report by 澳门玄机图 delivered in 2020, The Bureau of Ocean Energy Management (BOEM) requested an update to include additional data on geohazards that developers of wind farms must consider during site selection.

Project history

The Bureau of Ocean Energy Management's (BOEM) mission is to manage lease areas for offshore wind in an听environmentally and economically responsible way. In a previous study by 澳门玄机图 for BOEM, titled "Potential earthquake, landslide, tsunami and geo-hazards for the U.S. Offshore Pacific Wind Farms",听we听assessed the potential threats to wind energy development, including the effects of geo-hazards on听mooring and anchorage systems and buried transmission lines.

This report titled "Geohazard analysis and suitability updates for California Floating Windfarms鈥� updates the first study by incorporating additional newly acquired geophysical and geotechnical data. The benefit of reassessing a site's suitability when further data is made available is that specific risks can be analyzed more accurately, and optimal sites can be chosen.

What area does the report cover

The study covers the Humboldt, Morro Bay and Diablo Canyon call areas, potential cable landing areas near the mainland, and a five-nautical mile radius extending seaward, to include possible anchorage and mooring locations.

New geological and geophysical data inputs

The data gaps identified in the Phase 1 report were filled with recently acquired geological and geophysical data inputs. The data augmented three components of site selection, seismicity, geology, and slope stability by providing additional and updated information on bathymetry and seafloor geology from regional mapping and near-surface seabed soil characterization.

What's next

As new data is collected by floating offshore wind farm developers, it could be integrated to improve the knowledge base created in this study.

Developers will still require site-specific seabed investigations for license blocks and cable burial or landing locations. However, this report and the provide developers with a headstart for screening sites, a critical first step in building the floating offshore windfarms California so desperately needs to meet their ambitious targets of 25 GW of clean, renewable offshore wind energy by 2045.
