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 Friday, and 7AM – 3PM, 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 61 barge (AIS - WEEKS 61 Barge) will move between the south and north sides of the cofferdam to excavate spoils within the cofferdam.  The Weeks 61 barge monitors VHF-FM channels 13 / 16 / 82.  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 526 will be on the northern side of the cofferdam and will be advancing the cofferdam east. Weeks 526 barge 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.  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 x 150 ft temporary marine structure to facilitate grouting and freezing operations to stabilize the ground beneath the Manhattan bulkhead in preparation for tunnel boring.  The 150 ft x 50 ft Joseph D barge with a 184 ft crane on deck will be moored along the west face of the temporary marine structure.  The 150 ft x 150 ft scow Angela will be moored on west side of the Joseph D barge.  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. 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. All four lighted buoys exhibit FL W 2.5s characteristics.

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 Dredge CHARLESTON can be contacted via VHF radio channels 13 and 5 or via phone at (757) 508-2326.\n       Vessels desiring to anchor within Marcus Hook Anchorage must be at least 650 feet in overall length and obtain permission from the COTP at least 24 hours in advance, at (833) 453-1007.  The COTP will permit, at maximum, two vessels at a time on a “first come, first served” basis in the anchorage for a period of 12 hours. Vessels under 650 feet in overall length may request to anchor in Marcus Hook Anchorage and may be approved on a case-by-case basis. \n\tAll mariners are requested to stay clear of the dredge, booster, floating (pontoon) and submerged pipelines, barges, derricks and operating wires about the dredge.  Operators of vessels of all types should be aware that the dredge and floating pipelines are held in place by cables, attached to anchors some distance away from the equipment.  Buoys are attached to the anchors so that the anchors may be moved as the dredge advances and the location of the submerged pipelines are marked by buoys on each side of the channel.  Mariners are cautioned to strictly comply with the Inland Rules of the Road when approaching, passing and leaving the area of operations, and remain a safe distance away from the dredge, booster, buoys, cables, pipelines, barges, derricks, wires and related equipment. \n\tOwners and lessees of fishnets, crabpots and other structures that may be in the vicinity and that may hinder the free navigation of attending vessels and equipment must remove these from the area where tugs, tenderboats and other attendant equipment will be navigating.  Since the project will be conducted twenty –four (24) hours per day seven (7) days a week, all fishnets, crabpots and structures in the general area must be removed prior to the commencement of the work.
