November 8, 2024: The Office of Navigation Systems (CG-NAV), in coordination with the Bureau of Safety and Environmental Enforcement, Bureau of Ocean Energy Management and NOAA's National Marine Fisheries Service, is sponsoring a study by the National Academies of Sciences, Engineering, and Medicine (NASEM) to examine the impacts of offshore renewable energy activities on the West Coast. This study will specifically assess the effects on U.S. Coast Guard (USCG) missions, shipping routes (both current and future), as well as on commercial and tribal fisheries. To conduct this study, NASEM will assemble a committee of subject matter experts to carry out the research and produce a report that will be useful to the USCG and the Department of the Interior in informing their decision-making processes. Nominees should be subject matter experts in one or more of the below categories:

  • Coast Guard operations: specifically, navigation, shipping, safety at sea, search and rescue (including HF radar);
  • Fisheries science: stock distribution, Pacific Fishery Management Council ecosystem plan, and response to climate and other environmental change;
  • Fisheries management: Tribal, state, and federal commercial and recreational fisheries regulations and policy, including Pacific groundfish, coastal pelagics, Pacific salmon, and highly migratory species;
  • Marine geotechnical, engineering, and logistics: offshore energy facility siting (including assessment of geohazards), installation, and operation (including consideration of onshore requirements for installation and operation related to energy distribution systems);
  • Marine navigation: shipping lanes, aids to navigation including radar; or
  • Marine and maritime policy: Tribal concerns, spatial planning, stakeholder engagement.

If you have any questions or concerns about the process, please contact Mr. Brian Mottel at David.B.Mottel2@uscg.mil.

National Academies staff will be using the suggestions for experts (see nomination form link below) to build a committee of approximately 12-14 volunteer experts in addition to collecting information for potential speakers, participants, and peer reviewers for any publications resulting from the activity. Suggestions are due by November 20, 2024.

Nomination Form: https://survey.alchemer.com/s3/8064864/Impacts-on-Shipping-and-Commercial-Tribal-and-Recreational-Fisheries-from-Development-of-Renewable-Energy-on-the-West-Coast-Call-for-Experts

September 11, 2024: The U.S. Coast Guard Navigation Center (NAVCEN) announced upcoming changes to the Local Notice to Mariners (LNM) and the Light List, as part of their efforts to modernize and improve the accessibility, accuracy and overall user experience for mariners and other stakeholders.

Upcoming changes will 1) Transition from Paper Charts, 2) change the way that LNMs and Light Lists are accessed, 3) update LNM and Light List data refresh rates and 4) eliminate weekly LNMs, weekly Light List correction files, daily discrepancy files and the Summary of Light List Changes. The modernization of this information delivery is designed to improve the U.S. Coast Guard’s aid-to-navigation data management and dissemination capabilities. Frequent updates, geospatial visualization, and digital access are intended to enhance maritime safety, improve accessibility and increase efficiency.

Please review NAVCEN's LNM and Light List Change Notice for detailed information.


August 16, 2024: Please see our new page on Maritime Communications. This page is intended to provide information and resources related to communications equipment and requirements in the maritime sector.

April 22, 2024: The Coast Guard announced Change 1 to NVIC 02-23, Guidance on the Coast Guard's Roles and Responsibilities for Offshore Renewable Energy Installations (OREI) on the Outer Continental Shelf (OCS), dated 27Mar2023 via Maritime Commons blog post. The purpose of this NVIC is to provide guidance to Coast Guard Program Offices, Unit Commanders, and OREI developers on the Coast Guard’s roles and responsibilities throughout the Department of Interior’s development of offshore renewable energy on the OCS. This NVIC identifies information the Coast Guard will use to evaluate and mitigate the potential impacts of OREI leasing, construction, and operations on the Marine Transportation System (MTS); navigation safety; vessel traffic; traditional uses of waterways; and Coast Guard missions. This guidance will assist the Coast Guard in streamlining intra- and inter-governmental information sharing. It also provides relationship expectations to provide Coast Guard input to the Bureau of Ocean Energy Management (BOEM) and the Bureau of Environmental Enforcement (BSEE) in the execution of authorities under 30 CFR Part 585 and Part 285, such as the review of OREI project plans and associated environmental reviews. Additionally, this Circular provides guidance to members of industry, port safety and security stakeholders, and the public on the Coast Guard’s role and responsibilities in the OREI leasing and plan review process.

The historic letters of promulgation have been inserted into the linked copy. This NVIC was initially published on 05Oct2023. Enclosure (6) to the NVIC was updated on 11Dec2023. CH-1 incorporates numerous changes, with the majority centered around Enclosures (1) through (6) and clarifies details necessary to provide Navigation Safety Risk Assessments for review as part of the Construction and Operations Plan for OREI.


April 1, 2024: BSEE Director Kevin Sligh, BOEM Deputy Director Walter Cruickshank (on behalf of BOEM Director Elizabeth Klein) and U.S. Coast Guard Deputy Commandant for Operations (CG-DCO), Vice Admiral Peter Gautier, signed a new Memorandum of Understanding (MOU) regarding non-mineral energy installations and vessels. This MOU between the Bureau of Safety and Environmental Enforcement, the Bureau of Ocean Energy Management and the U.S. Coast Guard supersedes BOEMRE/USCG MOA OCS-06 dated July 27, 2011. Enclosure (1) provides agency contacts and Enclosure (2) provides a list of Memoranda of Agreement that will be covered by the MOU (to be populated at a future date). The non-mineral energy MOU is available on the BSEE/BOEM tab of our MOUs and MOAs page. As a reminder, the updated mineral-based MOU between BSEE and USCG was signed on December 13, 2023 (see the "Recent News" tab).

See the group picture of BSEE, BOEM and CG personnel present for the signing ceremony.


November 16, 2023: NVIC 03-23, Guidance on Guidance on Navigational Safety in and around Offshore Renewable Energy Installations (OREI) was published.

This NVIC highlights considerations when planning and undertaking voyages in the vicinity of OREIs in U.S. waters. Mariners should review and consider the contents of the NVIC prior to navigating within or in the vicinity of an OREI. In this NVIC, the term "mariner" includes masters, officers, crew, skippers and recreational users on all types of vessels and personal watercraft. The NVIC assists mariners making informed risk assessments for their intended voyage. The information provided in this NVIC should be considered together with the guidance on voyage planning and safe navigation found in the references. OREI structures are a new development on the U.S. Outer Continental Shelf (OCS).
