HONOLULU — The Coast Guard began temporarily moving aids to navigation in Hilo Harbor, Hawai’i, Sunday, to assist the U.S. Army Corps of Engineers with planned dredging operations.
As previously released, the U.S. Army Corps of Engineers’ hopper dredge Essayons will conduct maintenance dredging in March and April starting in Nawiliwili last week, and then at Kalaeloa (Barbers Point), Hilo, Kahului, and Honolulu harbors. Mariners should NOT rely on the aids to navigation that are relocated.
Mariners entering or departing Hilo Harbor during this time period are encouraged to contact the Essayons to determine the location of dredging operations and coordinate passing arrangements. Mariners should transit at their slowest safe speed to minimize wake when in the vicinity of the dredge and proceed with caution after passing arrangements have been made.
All waterway users should transit with caution when in the vicinity of the dredging vessel and operate at a safe speed when the potential for hazards such as dredging components are present. During operations near Barbers Point no aids will need to be moved but mariners should exercise caution around dredging operations.
The following buoys will be temporarily relocated starting March 27, 2016 through April 11, 2016. These dates may vary due to unforeseen on-site conditions, weather and other factors. See attached graphic.
Hilo Harbor Buoy 6 (LLNR 28080) relocated in approximate position 19-43-51.80N/ 155- 03-51.00W in 12ft of water.
Hilo Harbor Buoy 7 (LLNR 28085) relocated in approximate position 19-44-06.62N/ 155- 03-40.04W in 12ft of water.
Hilo Harbor Lighted Buoy 9 (LLNR 28105) relocated in approximate position 19-44- 05.10N/ 155-03-28.00W in 12ft of water.
Hilo Harbor Lighted Buoy 10 (LLNR 28110) relocated in approximate position 19-43- 44.95N/ 155-03-29.77W in 10ft of water.
Again, the relocated buoys may be in shoal water and should NOT be used for navigation.
General safety information regarding operating in the vicinity of dredging vessels can be found in Coast Guard Marine Safety Alert 14-15. This safety alert and other information about the 2016 Maintenance Dredge Project can be found on the Sector Honolulu homeport website http://ift.tt/1Ragb4X
Hawaii is a maritime state over 2,400 miles from the mainland and far more dependent on its harbors than most of the United States. The Hawaii state DOT claims that over 80 percent of all consumer goods – food, clothing, autos, building supplies, machinery, paper, and allied products, medical supplies, and agricultural materials – are imported into the state. Of that 80 percent, approximately 98 percent enters Hawaii though commercial harbors on the major islands.
To ensure that these vital goods continue to arrive safely in Hawaii, the Essayons crew will dredge approximately 290,000 cubic yards from the five key harbors. The dredge-material will be safely disposed of at EPA-designated ocean disposal sites.
