Tampa Harbor Maintenance Dredging 2017

Cashman was contracted by USACE, Jacksonville District to perform maintenance dredging along the length of the Tampa Bay Federal Navigation Channel with the goal of removing shoaled material.

PROJECT HIGHLIGHTS

• Dredged along the length of the Tampa Bay Federal Navigation Channel encompassing Hillsborough Bay Cuts A, C & D with a minor project extension into East Bay.
• Over 600,000 cubic yards (CY) of material was removed.
• Dredged material was hydraulically pumped into DMMA Site 3-D; ~2,000 linear feet of floating and submerged pipeline was placed in line with the Kraken offloader to the shoreline.  
• The offloader acted as a booster pump for the Atchafalaya, providing additional pumping power. It also transferred material from the Dale Pyatt’s scows via a customized excavator/platform and drag flow pump.
• Work included turbidity monitoring, sea turtle trawl sweeping and relocation, endangered species observers, and operation and maintenance of DMMA Site 3-D at the direction of the Contracting Officer.
