Vessels will be monitoring VHF-FM channels 07 and 12/16 \n\nThe purpose of the Port Everglades Sand Bypass project is to create infrastructure on the north side of the Port Everglades Inlet in Broward County, Florida. Work to be completed under this contract consists of dredging a sand trap and a portion of the rubble spoil shoal and disposal of the dredge material in the Port Everglades Harbor Ocean Dredged Material Disposal Site (ODMDS). Dredging operations are anticipated to commence on October 22, 2025, and will take place 24 hours a day, 7 days a week. With an estimated completion date of July 18, 2027. The DREDGE 54, along with DREDGE NEW YORK which will start on or about December 18, 2025, are planned to collectively dredge more than 400,000 CY of material from the north side of the Port Everglades entrance channel, immediately seaward of the north jetty and beach north of the inlet. The dredges would appreciate slow bell passing.\n\nWhile approaching the jetty dredging work area location. The material will be placed into scows and towed to the Port Everglades Harbor ODMDS, which is located approximately 3.1 nautical miles northeast of the entrance to Port Everglades Channel, outside of State Waters. \n\nThere is a project tow route between Red Buoy 2 and the ODMDS CenterPoint. Fishermen and trawlers should be aware of limited mobility for tug and scow transits. Small-Vessel Captains should take caution to avoid passing between the scow and towing tug while under transit. While not always visible at a distance, there is a large steel-tow cable that passes between the bow of the scow and the stern of the towing tug. The survey vessel, Pearl River, will conduct survey operations of the ODMDS disposal area and work area corridors (during daylight hours/7 days per week). A crew transfer vessel, the Cooper River, will transfer crew between the shoreside boarding location at Bahia Mar Yachting Center and the dredging equipment. \n\nDisposal Location: \n26.1315693N / 080.0333404W\n26.1315700N / 080.0305700W\n26.1211186N / 080.0305709W\n26.1211207N / 080.0333410W\n\nDredging Location:\n26.0942747N / 080.1060199W\n26.0945457N / 080.1057116W\n26.0947778N / 080.1053881W\n26.0947770N / 080.1049664W\n26.0948133N / 080.1046524W\n26.0948637N / 080.1045246W\n26.0949547N / 080.1044314W\n26.0952883N / 080.1040902W\n26.0954573N / 080.1040690W\n26.0969380N / 080.1038831W\n26.0969390N / 080.1040363W\n26.0977375N/ 080.1039367W\n26.0977215N / 080.1013560W\n26.0961361N / 080.1013842W\n26.0961403N / 080.1020684W\n26.0958314N / 080.1022291W\n26.0953104N / 080.1022933W\n26.0949923N / 080.1025778W\n26.0949941N / 080.1028349W\n26.0943524N / 080.1027938W\n26.0942799N / 080.1052630W","COORDINATES_JSON":"{\"type\":\"Polygon\",\"coordinates\":[[[-80.02404,26.13687],[-80.03079,26.1367],[-80.03081,26.12263],[-80.10443,26.09771],[-80.10486,26.09498],[-80.10536,26.09489],[-80.10574,26.09391],[-80.09832,26.09397],[-80.03015,26.12023],[-80.02377,26.1201],[-80.02404,26.13687]]]}","COORDINATES_TYPE":"Polygon","DECIMAL_LONGITUDE":null,"DECIMAL_LATITUDE":null}},{"type":"Feature","id":29324,"geometry":{"type":"Polygon","coordinates":[[[-97.05985999999996,27.847210000000075],[-97.06170999999995,27.844990000000053],[-97.07182999999998,27.843110000000024],[-97.07107999999994,27.839770000000044],[-97.06112999999999,27.841950000000054],[-97.05680999999998,27.841990000000067],[-97.05431999999996,27.839900000000057],[-97.05114999999995,27.838220000000035],[-97.04195999999996,27.833340000000078],[-97.03017999999997,27.827890000000025],[-97.01093999999995,27.817270000000065],[-96.98891999999995,27.80573000000004],[-96.98738999999995,27.807750000000055],[-97.05020999999994,27.841500000000053],[-97.05119999999994,27.843920000000026],[-97.05430999999999,27.846490000000074],[-97.05985999999996,27.847210000000075]]]},"properties":{"ESRI_OID":29324,"MSI_UID":29324,"ATU":8,"TITLE":"Aransas Pass To Baffin Bay - Aransas Pass/General/Marine Construction (Excluding Bridges)/Dredging","STATUS":"Approved","MSI_GROUP":"General","SUB_CATEGORY":"Marine Construction (Excluding Bridges)","TYPE":"Dredging","WTRW_UID":100116385156,"MRN":"urn:mrn:iala:wwy:us:navIV:dis8:seccorchrexcecozon:seccorchrtersea:seccorchrsublanact:arapastobafbay:arapas","WATERWAY_NAME":"Aransas Pass","CREATE_DATE":1759168688000,"MODIFIED_DATE":1779884498000,"BEGIN_DATE":1759104000000,"END_DATE":1784678399000,"DESCRIPTION":"Aransas Pass - Corpus Christi Channel - Dredge Operation --- From: 2025-10-12 To: 2026-07-20 --- The Dredge STUYVESANT will conduct dredging in the Aransas Pass Channel and Corpus Christi Channel, from east of Aransas Pass Lighted Buoy 3 (LLNR-28140) to the Port Aransas Ferry Terminal.

The USCG has established a Safety Zone, 33 CFR 165.T01-0336 Safety Zone; Hudson River, Manhattan, NY. Mariners transiting west of the safety zone should proceed at a speed to minimize potential wake or surge damage to the vessels working the construction area. There are two distinct jobsites within the construction area. The first jobsite, which is operated by Weeks Marine, is west of Pier 66. Within this jobsite, Weeks Marine is conducting soil mixing within a 110’ wide x 600’ long cofferdam for the Hudson River Ground Stabilization (HRGS) Project. Work hours are approximately 7AM – 7PM, Monday through Saturday. The cofferdam is marked with FL W 4s lights at each corner and at 30 ft intervals, and with white retro-reflective tape 6” high and at least 4’ long is installed above the MHHW mark every 50 feet on the cofferdam. The Weeks 263 barge (AIS- WEEKS 263) and material barges will be on the southern side outside of the cofferdam to support drilling operations within the cofferdam. The Weeks 263 barge monitors VHF-FM channels 13 / 16 / 67. The Weeks 61 barge (AIS - WEEKS 61 Barge) will move between the south and north sides of the cofferdam to excavate spoils from within the cofferdam. Two dump scows and a deck barge will also be on site. The Weeks 61 barge monitors VHF-FM Channel 13 / 16 / 82.  Starting on or about June 15th, 2026, the Weeks 526 barge (AIS- WEEKS 526) and material barges will be on the northern side outside of the cofferdam to advance the cofferdam east. The 526 will remove piles from the west end, lay them down on barges, shift east, and reinstall them. The Weeks 526 barge monitors VHF-FM channels 13 / 16 / 66.\n The second jobsite, which is north of Pier 66 in close proximity to the Manhattan bulkhead and near position 40-45-15.270N, 074-0-28.007W, is operated by Frontier-Kemper Tutor Perini JV. Within this jobsite, Posillico Civil has constructed a 200 ft x150 ft temporary marine structure to facilitate grouting and freezing operations to stabilize the ground beneath the Manhattan bulkhead in preparation for tunnel boring. All barges require tug assistance for a movement and a minimum notice of 24 hours via VHF radio is required for any barge relocation. All moored barges display fixed white lights in accordance with the Inland Navigation Rules. From June 8, 2026 to June 12, 2026, Aqua Survey, Inc. will be on site conducting sediment sampling operations. As part of this operation, R/V Prattis or R/V Tesla will be on scene from 7AM to 5PM monitoring VHF-FM Channels 13 / 16. Additionally, Normandeau Associates, Inc., will be conducting benthic macroinvertebrate ponar grabs and bottom fish samples via trawl. Privateer 2 (P2) will be on site from 7AM to 5PM monitoring VHF-FM Channels 13 / 16. Four seasonal white lighted buoys have been reset. Two (LLNR 37663, 37663.1) are upriver of the construction area, and two (LLNR 37663.2, 37663.3) are downriver.

This safer harbor location is between Burnt Porcupine Island and Long Porcupine Island, east of Rum Key. Vessels may leave this safe harbor location on a heading of 210° back into the work zone. The above described safe harbor locations may be reached in the opposite direction if chosen. The Crane Barge will not be sitting in the federally marked navigation channel while repairing the breakwater. Should any construction vessels need to leave the work zone for safe harbor they shall exit the work zone and travel across the navigation channel to a designated safe harbor point that is located west of Burnt Porcupine Island. An alternate designated safe harbor point is located between Burnt Porcupine Island and Long Porcupine Island, east of Rum Key. The crew will be working Monday through Friday during daylight hours. The Crane and attendant plant will both monitor marine VHF Channel 16. Mariners are urged to use extreme caution and transit the area at a safe speed.
