Client: City of New Bedford
Project: City of New Bedford Top of CAD 2 Cell Dredging
Date: Jun 2008- July 2008

The New Bedford Harbor CAD cell clean up job consisted of removing the contaminated material from the top of CAD 2 and placing it in CAD 1. The “top” material varied greatly in consistency and as such, the amount of dredge face changed constantly throughout the site. Similarly, the different materials had different hold over requirements for “settling” before they could be disposed of in CAD1. This required the use of all of our 1,500 cubic yard scows to maintain constant production. Disposal in the CAD required full fore and aft DGPS/WINOPS guidance of scow & push boat combinations, as CAD1 was nearly at capacity and bottom elevations were critical. All debris found on-site had to be washed in filter fabric lined containers prior to disposal. The SAMSON III, pushboat MANTIS, 1,500 cy scows 103 & 104, as well as the dump scow MUDCAT were all critical pieces of the job.
