New Bedford Marine Commerce Terminal
|Client:||Massachusetts Clean Energy Center|
|Project Date:||March 2013 - December 2014|
CASHMAN and our joint venture partner Weeks NB were contracted to perform dredging and marine construction to provide a multi-purpose facility designed to support the construction, assembly, and deployment of offshore wind projects, as well as handle bulk, break-bulk, container shipping and large specialty marine cargo. The first of its kind in North America, the Terminal was engineered to sustain mobile crane and storage loads that rival the highest load-bearing ports in the nation (loads of 4,000 pounds per square inch). Located in the heart of New England on the Atlantic Coast of the United States, the Terminal has easy access to open water and is in a prime position to take advantage of both domestic and international shipping opportunities. The terminal offers 1,200 linear feet of bulkhead, including 800 feet of deep-draft berthing and 400 feet of barge berthing space, 29-foot controlling depth in the New Bedford Harbor (MLLW), and 26 acres of terminal storage.
- The CASHMAN JV provided 910,000 cubic yards of dredging, including clean-up of 250,000 cubic yards of PCB-contaminated sediment.
- Constructed a Confined Aquatic Disposal (CAD) Cell requiring 350,000 cubic yards of dredging.
- Dredged to -32 feet into rock in front of new bulkhead.
- Mined 250,000 cubic yards to deepen the berth for reuse within the new constructed containment wall.
- Conducted drilling & blasting for 25,000 cubic yards of rock.
- Installed 13 major cofferdam bulkhead sheet pile cells with 60-ft diameters.
- As part of the state’s Fish Deterrent Plan, CASHMAN placed a series of engineered barriers to lessen detrimental effects to fish by excluding them from a proposed work area. Barriers included a fish weir, silt curtain, and bubble barrier.
- Managed installation of 1,000 feet of linear bulkhead and wharf, covered by 6,000 cubic yards of cast-in-place concrete.
