In May, Orion Marine Construction completed a maintenance dredging project along the Intracoastal Water- way channel to -10 feet MLLW in a 4.5-mile section from the Port of Palm Beach to the Town of Palm Beach docks in Palm Beach County, Florida. This photo shows work near the end of active dredging. Orion works to offload maintenance material onto the northern end of Palm Beach County's Tarpon Cove Restoration Area. The offloading machine is a Komatusu PC1250 with a 5-cubic-yard hydraulic bucket for mechanical offloading. The hopper barge (260 feet x 52 feet x 12 feet) transported the material from the dredging location to the Tarpon Cove restoration project, located about one mile south of the southern project limit. When filled to capacity the hopper barges could hold 3,900 tons of material; however, shallow depths in the offloading area restricted barges to a maximum of 1,850 tons. The second barge is a 120-foot material barge used to support the dredg- ing and offloading operations throughout the project. Orion's tugboat, the 2508, is working on-site, and on the island, a rental tracked excavator is doing final grading and cleanup operations.
