FLORIDA – JACKSONVILLE – ST JOHNS RIVER – MAYPORT: Dredge Operations
Cashman Dredging and Marine Contracting Company, LLC will begin dredging operations on or about February 2, 2017, in Jacksonville Harbor, Duval County, Florida. Dredging operations will be conducted within the Federal Navigation Channel encompassing the St. Johns River from Bar Cut-3 to Bar Cut-9. The project will involve the Trailing Suction Hopper Dredge “ATCHAFALAYA” removing shoaled material from the Federal Channel and then transiting to a mooring barge adjacent to the Buck Island Dredged Material Management Area. The mooring barge will be positioned along the south side of St. Johns River, outside of the Federal channel and secured with spuds and have proper lighting for nighttime operations. Approximately 300 linear feet of floating pipeline will be placed in line with the mooring barge to the shoreline. The floating pipeline will be marked with lighted buoys, for local traffic. The dredge will be supported by the survey vessel “SURVEY 2” and various other support vessels. All vessels will monitor VHF channels 16, 13, 12, and use 74 as the working channel. Mariners are urged to transit at their slowest safe speed to minimize wake and proceed with caution after passing arrangements have been made. The dredge will operate 7 days a week, 24 hours a day.
The work is scheduled to be completed on or about April 8, 2017. Chart 11491 LNM 04/17
