The almost 100-year old firm has many specialties, including the ability to construct innovative, complicated tonnage for its own purposes. The slowdown in barge construction in some sectors hasn’t dampened the need for specialty barges in other areas. In many cases, these mission requirements can involve the repurposing of existing tonnage using sometimes innovative and unusual design parameters. Such was the case when Cranford, NJ-based Weeks Marine (WMI) completed the conversion of an existing ABS deck barge into a loadline compliant, semi-submersible, all self-contained unit.

Photo: Magnolia Dredge

When maritime stakeholders think about dredging, they typically first conjure up visions of harbor deepening projects to accommodate those giant, post-Panamax boxships. Conversely, inland players hope for maintenance dredging in the heartland to keep the nation’s 31,000 cargo barges afloat as they head for the coast. But, there is much more to it than that. In Louisiana, dredging, of course, keeps Louisiana's waterways open for navigation, provides material for coastal restoration and helps industrial plants with drainage. The biggest projects are sponsored by the U.S.
