RPS 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 25GW of offshore wind by 2045, and multiple Floating Offshore Wind Farms (FOWF) must be built to meet this goal.
As a follow-up to the report by RPS 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.
The Bureau of Ocean Energy Management's (BOEM) mission is to manage lease areas for offshore wind in an environmentally and economically responsible way. In a previous study by RPS for BOEM, titled "Potential earthquake, landslide, tsunami and geo-hazards for the U.S. Offshore Pacific Wind Farms", we assessed the potential threats to wind energy development, including the effects of geo-hazards on mooring and anchorage systems and buried transmission lines.
This report titled "Geohazard analysis and suitability updates for California Floating Windfarms” 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.
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 GIS Portal - OceansMap 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.
