Offshore Wind Research and the Department of Marine Resource's Role

This page was updated January, 2025

Overview

°Õ³ó±ðÌýState of fb88 launched the in 2019 to explore the development of offshore wind (OSW) energy in the Gulf of fb88 that balances the needs of the state’s maritime industries and the health of the environment.

More information about fb88's OSW initiative and the Offshore Wind Roadmap can be foundÌý

In fb88, plans are taking shape for a research lease that strives to answer critical questions about the impacts of OSW on fishing and the environment prior to commercial development.Ìý

The Ìý(BOEM) is responsible for all renewable energy development in federal waters, including commercial and research offshore wind leases.Ìý On August 19, 2024, the State of fb88 and Bureau of Ocean Energy Management (BOEM) reached an agreement on a floating offshore wind research lease, a significant milestone in the development of offshore wind energy for fb88.

The goal of fb88's offshore wind research lease is to better understand the impacts of OSW on the ecosystem and fisheries in the area. To learn more about how the specific site was chosen for this research lease, goals of the project, or the State’s efforts around offshore wind planning, additional information can be found on the state’s project website.

The State of fb88 through the Governor's Energy Office is the lease applicant for the project, and its development partner,Ìý, will construct and operate the array.

Going Beyond BOEM Requirements for Surveys and Monitoring

For every OSW lease, BOEM requires studies that evaluate the impact of proposed activities on physical, biological, and socioeconomic resources and assess the seafloor and sub-seafloor conditions that could be affected by the construction, installation, and operation of towers, buoys, cables, wind turbines, and supporting structures.

As the lease applicant, theÌýState of fb88Ìýis responsible for submitting to BOEM a plan to conduct the studies and the information gained through the studies.ÌýDiamond Offshore Wind will develop the required plans and studies for BOEM on behalf of the state.

Consistent withÌýrecommendations in the fb88 Offshore Wind Roadmap, the State of fb88 will also go beyond these requirements by conducting additional surveys that produce a more comprehensive evaluation of the research lease area.Ìý

The Department of Marine Resources (DMR) will take the lead on many of the additional surveys on behalf of the state. ÌýSurveys planned by DMR will expand the spatial footprint, duration, frequency, and intensity of studies required by BOEM.

DMR will submit plans and studies to BOEM that are guided by recommendations from the Fisheries Working Group for the fb88 Offshore Wind Roadmap. The Roadmap describes how fb88 can develop offshore wind energy with minimal impacts to the marine ecosystem, coastal communities, and ocean users.

Pre-construction surveys will gather baseline data on local oceanographic conditions, resource abundance and distribution, and relationships between resources and ocean conditions. This information can then be compared to the data collected throughout the construction and operation phases of the research array to understand if/how conditions, abundances, distributions, and/or relationships change due to these construction and operation.Ìý

Surveys will include: Oceanographic monitoring; plankton and larval lobster survey; lobster trap survey; seafloor mapping and characterization; bottom trawl survey; active acoustic survey; highly migratory species monitoring; passive acoustic monitoring; visual wildlife survey; ecosystem modeling; and socio-economic and local historical knowledge survey. Ìý

Below is an illustration and table of each survey DMR will be conducting, indicating the type of survey, goal for each survey, and organizations partnering with DMR on the survey work.Ìý
