Brownsville Channel
Brazos Santiago Pass - Brownsville Channel - Dredge Operation --- From: 2024-08-28 To: 2026-03-26 --- Dredging is taking place in the Brownsville Channel and Brazos Santiago Pass Entrance Channel for the Brazos Island Harbor Channel Improvement and Rio Grande LNG Dredge Project. Operations will be conducted 24-hours a day, 7-days a week. The Cutter Suction Dredges OHIO and CAROLINA are currently working in the Brownsville Channel and pumping dredge spoils from the channel to the Upland Placement Areas located adjacent and south of the channel. The Dredge DODGE ISLAND will be working in the Brazos Santiago Pass Entrance Channel, alongside the Trawlers MR. TOMMY and JESSICA MARIE. Dredged material will be pumped through varying lengths of floating hose, submerged pipeline, pontoon pipeline and shore pipeline. Submerged pipeline has been installed along the south side of the ship channel between Laguna Madre Channel Light 15 (LLNR-29575) and Brownsville Channel Light 41 (LLNR-29940). Additional project equipment along the channel includes a subline crossing near Brownsville Channel A Range Rear Light (LLNR-42995), the BOOSTER 9 located west of Brownsville Channel Light 37 (LLNR-29915), and a spud barge with a floating dock along the green side of the channel, across from Laguna Madre Channel Light 28 (LLNR-29605). Additional support vessels/equipment include the Boosters JESSIE and CAPT. BARNEY, auxiliary equipment, pipe rafts, barges and towing vessels. Staging areas will be located throughout the project area, along the Brownsville Channel and Port Isabel Channel. Mariners should transit the project area with extreme caution and coordinate passing arrangements in advance. VHF-FM Channels: 10, 12 and 16, POC: (252) 342-4971 or (630) 207-3593

Location:
Dredging and Pipeline will be marked by pilings, with flashing 6sec AMBER lights attached. Pilings will be in place from July 2025 to October 2025
Continuing through December 2025, approximately 17,970 feet of new pipeline will be installed beneath the bottom of the James River by marine trenching operations from the south side of the federal shipping channel and federally maintained anchorage area to the Suffolk shoreline along a non-linear path, between latitudes/longitudes 36.948626°N, 076.419579°W and 36.904509°N, 076.431395°W. Pipe installations will be conducted using a “train”, consisting of four (4) individual barges in succession and moving in unison, including: two (2) trench excavation barges; one (1) pipe laying barge; and, one (1) trench restoration barge. Under normal conditions, it is expected the “train” will progress at the average rate of approximately 100 feet per day, with marine trenching, pipe installation and backfill efforts taking approximately 210 days to complete, including allowances for adverse weather conditions. Additional barges will be required for the delivery and storage of pipe and other construction materials. Each individual barge associated with these operations are expected to be approximately 60 feet in width and 180 feet in length and will be individually equipped with four (4) 360-degree visible white warning lights, one (1) light at each corner. Mariners are advised to avoid crossing, and use caution while transiting in proximity to, the “train”. At no time will this construction project affect, interfere with, obstruct, nor otherwise adversely impact marine traffic in the federal navigation channel or federally maintained anchorage area. Tug, barge and other vessel operations associated with these construction activities will monitor VHFFM channels 13 and 16 when work is in progress, or when vessels are operating in the project area.
