  • LNM: Temporary Research Area Established, off St. Andrew Bay


    This research area is southeast of the St. Andrew Bay inlet and c. 1 mile offshore of Lands End.

    FL – ST. ANDREW BAY – Temporary Buoys
    The University of Washington Applied Physics Laboratory will establish four (04) temporary lighted mooring buoys marking a mooring area for the anchored research vessel HUGH R. SHARP, near St. Andrew Bay in the Gulf of Mexico. READ MORE!

    The (04) temporary lighted mooring buoys will be temporarily established in the following 4 approximate locations: 30-03-39.0N 085-40-55.0W; 30-03-39.0N 085-40-48.0W; 30-03-33.0N 085-40-55.0W and 30-03-33.0N 085-40-48.0W. These (04) temporary lighted mooring buoys may only be deployed from July 1, 2017 until July 30, 2017.
    Mariners should exercise extreme caution and avoid navigating within 500 yards of these locations. The research vessel HUGH R. SHARP will be monitoring VHF-FM Channel 16, while on station. Any questions or comments regarding the (04) temporary lighted mooring buoys or the R/V HUGH R. SHARP should be directed to: Eric Boget, Applied Physics Lab – University of Washington, 1013 NE 40th Street, Seattle, WA 98105, (206) 685-1971, email: boget@apl.washington.edu or for other related marine safety matters you may contact the USCG Sector Mobile, Bldg

  • LNM: Update on Repairs, DuPont Bridge, East Bay, GIWW 295.5


    With a fixed vertical clearance of 50ft, the DuPont Bridge crosses the Gulf Waterway at Mile 295.5.

    03/29/2017: FL – GIWW – ST. ANDREWS BAY – Dupont Bridge – Rehabilitations – UPDATE Read More

    The repair work continues at the Dupont Bridge crossing the GIWW, mile 295.5, EHL, east side of the St. Andrew Bay, Bay County, Florida. Phase 1 spa ll work will resume on Span 13, moving in a northerly direction. Phase 2 has begun by working on the 4 dolphins first, then removing and replacing vertical timber work within the channel on one side at a time. The main navigation channel is located in Span 16. The fender system on the southeast quadrant was damaged on March 30, 2017, at 3:30 a.m. The channel is 150 feet horizontally, which may be affected by 55 feet
    from the barge measuring 150 feet by 45 feet, which will be spudded inside and outside of the channel at different times. The vertical clearance impact will only be within the work area during repairs. In an emergency, the equipment can be removed with one-hour notice. Assisting will be marine equipment of a 150-foot by 45-foot spud deck barge with supplies and materials. The M/V LLOYD W will be monitoring VHF-FM Channel 16. The project will continue until July 2017. Contractors will work 5 days a week, Monday through Friday, during daylight hours only. In an emergency, contact (850) 874-1500. Mariners should be alert for equipment in the waterway at all times, exercising extreme caution when passing and maintain slowest safe speed to minimize wake. The fender damage has been temporarily repaired until new facing is placed. Charts 11389, 11390, 11393 LNM 02/17

    FL – GULF OF MEXICO – U.S. Navy Testing READ MORE!


    Commencing February 28, 2017 and continuing until approximately December 31, 2017, the U.S. Navy will be conducting inert underwater mine and Airborne Mine Neutralization System (AMNS) destructor testing in the Gulf of Mexico, in an area approximately 39 nautical miles southwest of the Panama City Pass. The inert mine destructors are silver and orange, 3 feet long, 6 inches in diameter and weighs approximately 2 pounds in water, while weighing 35 pounds in air. Inert mine bottom shapes and inert miner destructors will be deployed, operated and tested in the below
    test areas during this period. AMNS testing will consist of surface ship operations to include the following: R/V SEWEE or R/V PATRIOT and Project Support Crafts (PSC) 02, 03, 05 or PSC 11; however, additional R/Vs may be added in the future. It is requested that all vessels maintain a one nautical mile CPA of all vessels while operations are in progress. All U.S. Navy / U.S. Navy contracted AMNS support vessels will monitor VHF-FM Channel 16. For up-to-date information, mariners can contact Mr. Robertson at (850) 230-7698.
